A practical South African guide to understanding turnover, gross profit, expenses, cash flow and what is really left after R100,000 in monthly sales
Seeing R100,000 in sales for the first time can feel like a major milestone.
For a small-business owner who started with a few customers, a WhatsApp catalogue, a spare room full of stock or a service they initially provided after hours, reaching six figures in monthly sales can make it feel as though the business has finally arrived.
Then the month ends.
The supplier wants R38,000.
Advertising consumed R12,000.
Couriers took another R7,000.
Software subscriptions, banking charges and payment-processing fees have gone off.
There are wages to pay.
Stock needs to be reordered.
Some money needs to remain available for tax.
And the R100,000 that looked enormous when you checked your sales dashboard suddenly feels considerably smaller.
Perhaps only R15,000 is genuinely left.
Or R30,000.
Or, despite R100,000 in sales, you may actually have made a loss.
That isn’t unusual mathematics. It is simply the difference between turnover and profit.
Statistics South Africa defines turnover broadly as money generated from sales of goods or services and certain other business activities. Historical Stats SA data also illustrates the enormous role of smaller firms: small businesses generated about R2.3 trillion, or 22%, of formal-sector business turnover in 2019. (Statistics South Africa)
But turnover answers only one question:
How much did the business sell?
It does not answer:
How much did the business keep?
That second question is the focus of this guide.
The R100,000 Question
Suppose three South African businesses each report exactly:
R100,000 in monthly sales.
Business A is an independent consultant.
Business B sells products online.
Business C operates a small physical retail business.
Would all three owners make the same amount?
Not even close.
Here’s a simplified example:
| Consultant | Online Store | Retail Business | |
|---|---|---|---|
| Monthly sales | R100,000 | R100,000 | R100,000 |
| Direct costs | R8,000 | R42,000 | R55,000 |
| Operating expenses | R27,000 | R33,000 | R31,000 |
| Illustrative operating profit* | R65,000 | R25,000 | R14,000 |
| Operating margin | 65% | 25% | 14% |
*Simplified examples before applicable tax, owner remuneration/distributions and other adjustments.
Same sales.
Completely different businesses.
This is why saying:
“My business makes R100,000 per month”
doesn’t tell us very much.
A better question is:
“Out of every R100 my customers pay me, how much is actually left after delivering the product or service and running the business?”
That is where things become interesting.
Turnover, Revenue, Gross Profit and Net Profit Are Not the Same Thing
Business terminology can sound unnecessarily complicated.
The underlying ideas are actually straightforward.
Revenue or turnover
For our purposes, this is the money generated from selling your products or services before deducting the associated business costs.
If you sell:
200 items × R500
your sales revenue is:
R100,000
You have not necessarily made R100,000.
You have sold R100,000.
Cost of Sales
Next comes the cost directly associated with what you sold.
Suppose those 200 products cost you R260 each to purchase or manufacture.
200 × R260 = R52,000
Your calculation becomes:
R100,000 sales
− R52,000 cost of goods sold
= R48,000 gross profit
That R48,000 still isn’t necessarily yours.
You haven’t paid the other costs of operating the business.
Gross Profit
Gross profit tells you what remains after deducting the direct cost of producing or acquiring what you sold.
The formula is:
Revenue − Cost of Sales = Gross Profit
In our example:
R100,000 − R52,000 = R48,000
Your gross profit margin is:
R48,000 ÷ R100,000 × 100
= 48%
This number is extremely useful.
It tells you that for every R100 of sales, approximately R48 remains after direct product costs, before your other operating expenses.
Operating Expenses
Now come the costs required to keep the business running.
Depending on the business, these might include:
- salaries and wages;
- rent;
- electricity;
- internet;
- advertising;
- accounting;
- software;
- insurance;
- telephone costs;
- bank charges;
- payment-processing fees;
- courier expenses;
- vehicle expenses;
- security;
- website hosting;
- professional services.
Suppose these total R30,000.
Your R48,000 gross profit becomes:
R48,000
− R30,000
= R18,000
Now we are much closer to understanding what the business actually generated.
Profit Margin: The Number Every Business Owner Should Know
If the simplified operating profit is R18,000 from R100,000 sales:
R18,000 ÷ R100,000 × 100
= 18% operating margin
Put differently:
For every R100 coming through the till, approximately:
R82 goes back out through costs.
R18 remains before applicable taxes, owner remuneration/distributions and other adjustments.
That is a very different mental picture from:
“I made R100,000.”
Visual Graph: What Happened to the R100,000?
This would work extremely well as your first large horizontal graphic.
Example: Product Business
R100,000 SALES
↓
R52,000 — Product costs
↓
R48,000 — Gross profit
↓
R30,000 — Operating expenses
↓
R18,000 — Operating profit
A horizontal visual could show the R100,000 bar progressively shrinking.
The important message underneath:
Sales measure how much money came through the business. Profit measures how much survived the journey.
Why R100,000 in Your Bank Account Isn’t Necessarily Profit Either
This is another common trap.
Imagine checking your business banking app on Friday.
Balance:
R107,500
Fantastic.
But Monday is supplier-payment day.
R38,000 is due.
Staff:
R18,000.
Rent and utilities:
R11,000.
Advertising debit order:
R8,000.
Courier account:
R6,500.
Software and subscriptions:
R2,000.
Your real picture looks like this:
| Current bank balance | R107,500 |
|---|---|
| Supplier commitments | -R38,000 |
| Staff | -R18,000 |
| Rent/utilities | -R11,000 |
| Advertising | -R8,000 |
| Couriers | -R6,500 |
| Software | -R2,000 |
| Cash after listed commitments | R24,000 |
And even that R24,000 may not all be freely spendable.
You could still have tax obligations, upcoming stock purchases, debt repayments or other costs.
Your bank balance is a snapshot.
It is not a profit-and-loss statement.
Case Study 1: Lerato’s Online Clothing Store
The case studies in this guide are illustrative composites designed to demonstrate realistic business calculations. They do not describe identifiable individuals.
Lerato runs an online clothing business.
After months of growing her Instagram, TikTok and WhatsApp customer base, she finally reaches:
Monthly sales: R100,000
She is ecstatic.
Her friends see the orders going out every day and assume the business is making serious money.
Let’s open the books.
Step 1: Stock
The products sold during the month cost:
R41,000
Gross profit:
R100,000 − R41,000
= R59,000
Gross margin:
59%
Still looking excellent.
But now the operating costs arrive.
Step 2: Advertising
Meta and TikTok advertising:
R13,000
Remaining:
R46,000.
Step 3: Delivery and packaging
Courier costs not recovered from customers:
R5,500
Packaging:
R1,500
Total:
R7,000
Remaining:
R39,000.
Step 4: Payment costs
Payment gateway, banking and related transaction costs:
R2,500
Remaining:
R36,500.
Step 5: Website and software
Hosting, ecommerce tools, email, design software and other subscriptions:
R2,500
Remaining:
R34,000.
Step 6: Assistance
Part-time packing/customer-service help:
R6,000
Remaining:
R28,000.
Step 7: Miscellaneous legitimate business costs
Returns, damaged packaging, telephone expenses and other operating costs:
R3,000
Illustrative operating profit: R25,000
Her R100,000 sales month produced roughly:
R25,000 before applicable tax and owner compensation/distributions.
Lerato’s R100,000 Breakdown
| Item | Amount | % of Sales |
|---|---|---|
| Sales | R100,000 | 100% |
| Stock | R41,000 | 41% |
| Advertising | R13,000 | 13% |
| Delivery/packaging | R7,000 | 7% |
| Payment/banking costs | R2,500 | 2.5% |
| Website/software | R2,500 | 2.5% |
| Assistance | R6,000 | 6% |
| Miscellaneous | R3,000 | 3% |
| Illustrative operating profit | R25,000 | 25% |
That’s not a bad business.
Quite the opposite.
But the owner isn’t personally earning R100,000.
Then Lerato Makes a Dangerous Mistake
Lerato sees R25,000 left and transfers all R25,000 to herself.
Next month she needs to buy additional stock.
Her supplier requires a large deposit.
Advertising also needs to start before the next batch of customer orders arrives.
Suddenly:
The business is profitable but short of cash.
This is where profit and cash flow separate.
Profit Does Not Automatically Mean Cash
Consider a service business.
You complete a R50,000 project in September.
The customer receives an invoice.
Your accounting may recognise the transaction according to the accounting method applicable to your business.
But the customer has 30-day payment terms.
You still need to pay:
staff;
internet;
rent;
fuel;
software;
suppliers.
A profitable invoice cannot pay those bills until cash is actually available.
This is why cash-flow management matters so much.
The Cash-Flow Gap
Imagine this timeline:
1 September
You spend R20,000 delivering a customer project.
20 September
Project completed.
Invoice issued:
R50,000
30 September
Staff and operating costs:
R15,000
20 October
Customer finally pays R50,000.
The project may have been profitable.
But you had to finance the business for weeks before receiving the money.
The larger your business grows, the bigger these timing gaps can become.
Growth itself can consume cash.
Case Study 2: Thabo’s Consulting Business
Thabo provides digital, technical and business services.
He doesn’t carry physical stock.
That immediately changes his economics.
Monthly sales:
R100,000
Contract freelancers:
R12,000
Software:
R4,000
Advertising/networking:
R5,000
Internet/telephone:
R2,000
Coworking/office:
R6,000
Accounting/admin:
R3,000
Travel:
R3,000
Other operating costs:
R5,000
Total operating costs:
R40,000
Simplified operating profit:
R60,000
Operating margin:
60%
Compare that with Lerato.
Both made R100,000 in sales.
Lerato’s simplified operating profit:
R25,000
Thabo’s:
R60,000
Difference:
R35,000.
Same turnover.
Very different economics.
But Don’t Immediately Assume Thabo Has the Better Business
Margins matter, but they aren’t everything.
Lerato may have a business that can eventually sell thousands of products without requiring her personally to perform every transaction.
Thabo may generate excellent margins because his expertise is the product.
But if Thabo stops working, perhaps revenue falls dramatically.
So when comparing businesses, consider:
- profit margin;
- owner dependence;
- scalability;
- recurring revenue;
- customer concentration;
- working-capital needs;
- business assets;
- debt;
- cash flow;
- growth potential.
A 60% margin doesn’t automatically make one business superior to another.
Visual Graph: Same R100,000 Sales, Different Results
This is an excellent place for your second visual graph.

Case Study 3: Ayesha’s Small Retail Business
Ayesha operates a small speciality shop.
Monthly sales:
R100,000
Her business has a different cost structure.
Inventory sold:
R50,000
Gross profit:
R50,000
Then:
Rent: R10,000
Employee wages: R10,000
Electricity/utilities: R3,500
Card/banking costs: R2,000
Security/insurance: R2,500
Advertising: R3,000
Internet/software: R1,500
Transport: R1,500
Miscellaneous: R1,000
Total operating expenses:
R35,000
Simplified operating profit:
R15,000
Margin:
15%
Again:
R100,000 came through the business.
Only R15,000 remains in this simplified example before tax and owner compensation/distributions.
Compare All Three Businesses
| Thabo: Consultant | Lerato: Online Store | Ayesha: Retail | |
|---|---|---|---|
| Sales | R100,000 | R100,000 | R100,000 |
| Direct/product costs | R12,000* | R41,000 | R50,000 |
| Other operating expenses | R28,000 | R34,000 | R35,000 |
| Operating profit | R60,000 | R25,000 | R15,000 |
| Margin | 60% | 25% | 15% |
*Freelancer costs are treated as direct costs for this simplified comparison.
This table demonstrates why turnover comparisons between businesses can be misleading.
The R100 Test
One of the easiest ways to understand your business is to reduce everything to R100 of sales.
For Ayesha:
Every R100 sale roughly becomes:
R50 → stock
R10 → rent
R10 → wages
R3.50 → utilities
R2 → banking/payment costs
R2.50 → security/insurance
R3 → advertising
R1.50 → software/internet
R1.50 → transport
R1 → miscellaneous
Leaving:
R15.
Now ask:
Would I still think of the R100 sale as R100 of my money?
Probably not.
Your Break-Even Point Matters More Than a Flashy Sales Number
Break-even is approximately the point where revenue covers your costs without producing meaningful profit or loss.
Suppose your business has:
Fixed monthly expenses:
R30,000
Gross margin:
40%
For every R1 in sales, approximately R0.40 contributes toward fixed costs and eventual profit.
Simplified break-even revenue:
R30,000 ÷ 0.40
= R75,000
That means:
R50,000 sales → likely below break-even.
R75,000 → approximately break-even.
R100,000 → approximately R10,000 contribution above the fixed-cost break-even point in this simplified model.
Understanding this number can be more useful than chasing an arbitrary turnover target.
Why More Sales Can Sometimes Make Your Cash Problem Worse
This sounds impossible until you’ve experienced it.
Imagine selling a product for:
R1,000
It costs you:
R600.
Your gross profit is:
R400.
You normally sell 50:
Sales = R50,000
Stock cost = R30,000.
Then a marketing campaign works brilliantly.
You receive demand for 200 products.
Fantastic.
Potential sales:
R200,000
But you now need:
R120,000 worth of stock.
Your supplier wants payment before shipping.
Customers may not all pay immediately.
Your business suddenly needs substantially more working capital precisely because sales are growing.
Growth can therefore create a cash requirement before it creates usable cash.
The Difference Between Markup and Margin
These terms are regularly confused.
Suppose a product costs:
R500
You sell it for:
R750
Profit before other expenses:
R250.
Markup:
R250 ÷ R500 × 100
= 50%
But margin is:
R250 ÷ R750 × 100
= 33.3%
A 50% markup does not mean a 50% gross margin.
That distinction can dramatically affect pricing decisions.
Why Small Expenses Matter at R100,000 Turnover
A business owner might say:
“It’s only R500.”
But recurring costs accumulate.
Consider:
Software A: R500
Software B: R800
Phone: R700
Bank charges: R900
Cloud storage: R250
Design tool: R350
Email system: R450
Miscellaneous subscription: R300
Total:
R4,250 per month
Annualised:
R4,250 × 12
= R51,000 per year
That’s why reviewing recurring expenses matters.
The point isn’t to cancel every useful tool.
A R2,000 tool that generates R20,000 of additional profit could be excellent value.
The goal is to eliminate expenses that no longer justify their cost.
Advertising: Expense or Investment?
Advertising is an expense in your accounts, but from a management perspective it should ideally produce an economic return.
Suppose you spend:
R10,000
and generate:
R40,000 sales.
It may look brilliant.
4× revenue relative to advertising spend.
But suppose the products sold cost R24,000.
Sales:
R40,000
Product cost:
−R24,000
Advertising:
−R10,000
Remaining before other operating expenses:
R6,000
That campaign’s economics look very different.
Never evaluate advertising using revenue alone.
Ask what happened to contribution and profit after advertising and fulfilment costs.
Discounts Can Destroy Margin Faster Than You Think
Suppose:
Normal price:
R1,000
Product cost:
R600
Gross profit:
R400
Gross margin:
40%.
You run a 20% discount.
New selling price:
R800
Product cost remains:
R600
Gross profit:
R200.
Your selling price fell only 20%.
But gross profit per unit fell from R400 to R200.
That’s a 50% reduction in gross profit per unit.
You would need to sell significantly more units just to generate the same gross profit.
This is why constant promotions can create impressive turnover while weakening profitability.
Revenue Vanity vs Profit Reality
There is nothing wrong with celebrating turnover milestones.
They represent genuine progress.
But turnover can become a vanity metric when it is disconnected from profitability.
Imagine:
Business A
Revenue: R50,000
Profit: R20,000
Business B
Revenue: R100,000
Profit: R10,000
Business C
Revenue: R200,000
Loss: R5,000
Which business is “winning”?
You cannot answer from turnover alone.
Graph: Revenue Can Rise While Profit Falls
Another excellent visual for SAWise:
| Month | Revenue | Operating Profit |
|---|---|---|
| January | R50,000 | R12,000 |
| February | R65,000 | R14,000 |
| March | R80,000 | R15,000 |
| April | R100,000 | R14,000 |
| May | R120,000 | R11,000 |
| June | R150,000 | R8,000 |
Sales triple:
R50,000 → R150,000.
Profit falls:
R12,000 → R8,000.
Why?
Perhaps the business:
- discounted heavily;
- spent too much acquiring customers;
- hired too quickly;
- experienced rising fulfilment costs;
- sold lower-margin products;
- suffered returns or wastage.
Growth without margin discipline can produce a larger but weaker business.
Taxes: Don’t Treat the Remaining Money as Automatically Spendable
Tax treatment depends on the business structure and tax regime.
For ordinary companies, South Africa’s corporate income-tax rate is currently 27% for years of assessment ending from 1 April 2026 through 31 March 2027. (South African Revenue Service)
But that does not mean you should simply take the operating profit in our examples and subtract 27%.
Why?
Because accounting operating profit in a simplified article is not necessarily the same as taxable income.
Deductibility, allowances, adjustments, business structure, assessed losses and other factors can affect taxable income.
Sole proprietors are also different: profits or losses from business or trade form part of the individual’s income-tax position. (South African Revenue Service)
So use the examples in this article to understand business economics, not to calculate your final SARS bill.
Small Business Corporation Tax Can Be Different
A qualifying Small Business Corporation may be taxed according to progressive rates rather than simply paying 27% from the first rand.
For years of assessment ending from 1 April 2026 to 31 March 2027, SARS lists:
| Taxable income | SBC rate |
|---|---|
| R1–R99,000 | 0% |
| R99,001–R365,000 | 7% above R99,000 |
| R365,001–R550,000 | R18,620 + 21% above R365,000 |
| Above R550,000 | R57,470 + 27% above R550,000 |
But qualifying conditions apply. SARS notes requirements including limits relating to gross income, shareholders and the nature of the business. (South African Revenue Service)
Don’t assume that because your company is “small”, SARS automatically regards it as an SBC for tax purposes.
Turnover Tax Is Another Important Distinction
South Africa also offers a simplified turnover-tax regime for qualifying micro businesses.
From the 2027 tax year, qualifying micro businesses can fall within this system where annual turnover does not exceed R2.3 million, subject to the eligibility rules. (South African Revenue Service)
Current taxable-turnover bands include:
| Taxable turnover | Rate |
|---|---|
| R0–R600,000 | 0% |
| R600,001–R950,000 | 1% above R600,000 |
| R950,001–R1.4 million | R3,500 + 2% above R950,000 |
| R1.4 million–R2.3 million | R12,500 + 3% above R1.4 million |
(South African Revenue Service)
Notice something important.
It’s called turnover tax for a reason.
The calculation is based on taxable turnover under that system, rather than conventional taxable profit.
This reinforces why business owners need to know which tax regime actually applies to them.
The VAT Threshold Changed in 2026
This is particularly relevant to an article built around turnover.
From 1 April 2026, South Africa’s compulsory VAT-registration threshold increased from R1 million to R2.3 million. The voluntary-registration threshold also increased from R50,000 to R120,000, subject to the applicable rules. (South African Revenue Service)
Why does this matter?
Because R100,000 monthly sales annualised equals:
R100,000 × 12
= R1.2 million annually.
Under the previous R1 million compulsory threshold, that level could have created an obvious VAT-registration issue if the relevant taxable-supply requirements were met.
Under the threshold effective from April 2026, R1.2 million is below the new R2.3 million compulsory threshold.
That doesn’t mean VAT is irrelevant—voluntary registration and other circumstances can still matter—but it demonstrates why using outdated financial articles can be dangerous.
Tax thresholds change.
Always verify current SARS rules.
Your Business Needs a Reserve Too
Suppose you finally calculate that your business genuinely produced R25,000 after its ordinary operating expenses.
Should you withdraw all R25,000?
Not necessarily.
What happens when:
the laptop breaks?
your vehicle needs repairs?
a large customer pays 30 days late?
a supplier increases prices?
sales suddenly fall?
you need to replace equipment?
your advertising account stops performing?
The business needs financial resilience just like a household does.
A Simple Business Reserve Calculation
Suppose essential monthly operating expenses are:
R40,000
One month of essential costs:
R40,000.
Two months:
R80,000.
Three months:
R120,000.
Six months:
R240,000.
There is no universal rule saying every business must hold exactly three or six months.
A low-overhead freelancer with recurring clients has different risks from a restaurant employing 15 people.
But operating with zero buffer leaves very little room for mistakes.
The Owner’s Drawings Can Quietly Destroy Profit
Suppose your business generates:
R100,000 sales.
After genuine operating costs:
R30,000 remains.
You transfer:
R10,000 on the 5th.
R5,000 on the 12th.
R8,000 on the 20th.
R6,000 on the 25th.
R4,000 at month-end.
Total:
R33,000.
You’ve removed more cash than the simplified monthly profit.
If this continues, the business may begin funding your personal lifestyle from:
previous reserves;
supplier credit;
new customer deposits;
debt;
or money needed for tax.
That can work temporarily.
Eventually the gap catches up.
A Better Monthly Money Routine
Instead of asking:
“What’s in the account?”
build a monthly business dashboard.
Track:
Revenue
How much did you sell?
Gross profit
What remained after direct costs?
Gross margin
What percentage of sales survived direct costs?
Operating expenses
What did it cost to run the operation?
Operating profit
What remained after ordinary operating expenses?
Cash position
How much cash is actually available?
Receivables
How much do customers still owe you?
Payables
How much do you owe suppliers?
Tax provisions
What needs to remain available?
Owner withdrawals/remuneration
How much went to you?
Those numbers tell a story.
Your bank balance alone does not.
Your Monthly Business Scorecard
Here’s a useful template:
| Metric | This Month | Previous Month |
|---|---|---|
| Revenue | R100,000 | R92,000 |
| Gross profit | R50,000 | R47,000 |
| Gross margin | 50% | 51.1% |
| Operating expenses | R32,000 | R30,000 |
| Operating profit | R18,000 | R17,000 |
| Operating margin | 18% | 18.5% |
| Cash available | R42,000 | R36,000 |
| Customers owing | R15,000 | R22,000 |
| Supplier amounts due | R19,000 | R17,000 |
Now you can see:
Revenue improved.
Gross profit improved.
But gross margin weakened slightly.
Expenses rose.
Receivables improved.
Cash increased.
That is useful business information.
Don’t Confuse Money Collected With Sales Performance
Suppose an old customer finally pays a R40,000 invoice this month.
Your bank account jumps.
But that doesn’t necessarily mean this month’s new sales increased by R40,000.
Similarly, you might make R100,000 in new sales but collect only R70,000 this month because customers haven’t paid the remaining R30,000.
That’s why you should understand both:
sales performance
and
cash collections.
They are related, but they aren’t identical.
Three Questions to Ask Before Celebrating a Record Month
If your business hits R100,000 for the first time, celebrate it.
Then ask:
1. Did gross profit increase?
If sales increased 40% but gross profit increased only 5%, investigate.
2. Did operating profit increase?
Maybe you spent heavily to generate those sales.
3. Did cash improve?
If profit increased but the bank account deteriorated, working capital may be absorbing the money.
Those three questions reveal far more than the sales figure alone.
What if You Make R100,000 With Almost No Expenses?
Excellent.
Some digital and professional businesses can have relatively low direct costs.
But “almost no expenses” still deserves examination.
What about:
your labour?
software?
equipment depreciation?
internet?
contractors?
marketing?
accounting?
tax?
insurance?
future equipment replacement?
If the owner works 250 hours per month without paying themselves, an apparently extraordinary margin may partly reflect unpaid labour.
Always ask whether the business economics would still make sense if someone else had to perform your work.
Your Time Has a Cost
Imagine:
Sales:
R100,000
Expenses:
R20,000
Profit:
R80,000
Fantastic.
But you personally work:
300 hours per month.
The business depends entirely on you.
If replacing your role would cost R35,000 per month, the economics need to be viewed in that context.
This doesn’t mean the R80,000 isn’t real.
It means understanding whether you own a scalable business or a highly profitable job can affect how you plan growth.
Increasing Prices Can Sometimes Beat Increasing Sales
Suppose you sell:
100 units × R1,000
= R100,000.
Cost per unit:
R700.
Gross profit:
R30,000.
Now suppose you increase the selling price by 10%:
R1,100.
If volume remained 100 units:
Revenue:
R110,000.
Cost:
R70,000.
Gross profit:
R40,000.
Revenue increased:
10%.
Gross profit increased:
33.3%.
Of course, real customers may react to price increases, so demand must be considered.
But this demonstrates why pricing can have a disproportionately large effect on profit.
Cutting Costs Can Have a Similar Effect
Original:
Sales: R100,000
Total costs: R85,000
Profit: R15,000.
You reduce unnecessary expenses by:
R5,000.
New costs:
R80,000.
New profit:
R20,000.
You reduced total costs by only:
5.9%.
But profit increased:
33.3%.
This is why small improvements in margin can dramatically affect the owner’s outcome.
The Dangerous Race for R1 Million Turnover
Many entrepreneurs set goals such as:
“R100k a month.”
“R1 million a year.”
“R10 million turnover.”
There is nothing wrong with those goals.
But imagine:
Business One
Annual revenue: R1 million
Profit margin: 25%
Profit:
R250,000
Business Two
Annual revenue: R2 million
Profit margin: 8%
Profit:
R160,000
Business Two has double the sales.
Yet the simplified profit is R90,000 lower.
Scale matters.
Margin matters too.
Original Comparison: R50k vs R100k vs R200k Sales
Let’s model a growing ecommerce operation.
| R50k Sales | R100k Sales | R200k Sales | |
|---|---|---|---|
| Product costs | R22,000 | R44,000 | R88,000 |
| Advertising | R6,000 | R13,000 | R32,000 |
| Delivery/packaging | R4,000 | R8,000 | R18,000 |
| Staff | R4,000 | R8,000 | R18,000 |
| Software/admin | R3,000 | R4,000 | R6,000 |
| Other | R2,000 | R4,000 | R8,000 |
| Total costs | R41,000 | R81,000 | R170,000 |
| Operating profit | R9,000 | R19,000 | R30,000 |
| Margin | 18% | 19% | 15% |
Revenue quadrupled:
R50,000 → R200,000.
Profit increased:
R9,000 → R30,000.
That’s good.
But profit did not quadruple.
Why?
Advertising, delivery and staffing became more expensive as the business scaled.
At R100,000 sales, the margin was 19%.
At R200,000:
15%.
The business became bigger but slightly less efficient.
That’s exactly the type of information owners miss when they watch turnover alone.
Visual Graph: The Growth Trap
Use this as another large graphic.
Sales
R50k → R100k → R200k
Profit
R9k → R19k → R30k
Margin
18% → 19% → 15%
Headline inside the graphic:
BIGGER SALES ≠BIGGER MARGINS
This is an original calculation based on the hypothetical model above, not an industry benchmark.
What Should You Do With the Profit?
Suppose R25,000 genuinely remains.
You could divide it between:
- owner compensation;
- business reserves;
- debt reduction;
- new equipment;
- marketing;
- expansion;
- stock;
- future tax obligations where applicable.
The right allocation depends on the business.
But simply transferring every remaining rand to your personal account can make growth unnecessarily difficult.
This connects directly with another important principle:
A business should eventually reward its owner without being financially weakened every time it does so.
Five Numbers Worth Knowing Every Month
If you remember nothing else from this guide, know these five.
1. Revenue
What did we sell?
2. Gross profit
What remained after direct costs?
3. Gross margin
How efficiently did products/services generate gross profit?
4. Operating profit
What remained after running the business?
5. Cash
Can we actually pay our obligations?
You don’t need to be an accountant to understand these concepts.
But you do need accurate bookkeeping.
A Simple Monthly Review
Set aside one hour after month-end.
Open your accounts.
Don’t start with the bank balance.
Start with the income statement or your properly maintained records.
Ask:
What did we sell?
Then:
What did those sales cost us?
Then:
What did running the business cost?
Then:
What remained?
Then:
Where is the cash?
If profit exists but cash doesn’t, investigate:
receivables;
stock;
debt repayments;
capital purchases;
owner withdrawals;
supplier payments;
timing differences.
This habit can expose problems long before they become crises.
Frequently Asked Questions
1. If my business makes R100,000 in sales, how much profit should I make?
There is no universal amount.
A professional service business might generate a high margin because it carries little stock, while a retailer could have substantial product, staff and premises costs.
In the three illustrative examples in this guide, businesses with identical R100,000 monthly sales produced operating profits ranging from R15,000 to R60,000.
Those are examples, not benchmarks.
Calculate your own:
Revenue − direct costs − operating expenses = simplified operating profit
Then consider tax, financing, owner remuneration/distributions and other applicable adjustments separately.
2. Is turnover the same as profit?
No.
Turnover measures sales or business revenue before expenses.
Profit is what remains after relevant costs are deducted.
A company can generate millions of rand in turnover and still make very little profit—or even make a loss.
That’s why turnover should never be used on its own to measure financial health.
3. Does money in my business bank account count as profit?
Not necessarily.
Your bank account may contain customer payments that will soon be needed for stock, suppliers, salaries, tax, rent or other commitments.
Similarly, profit can sometimes exist on the accounts while the related cash has not yet been collected from customers.
Your cash balance and accounting profit measure different things.
Both matter.
4. What is a good profit margin for a South African small business?
There is no single “good” margin that applies to every industry.
A consultant, supermarket, building contractor, ecommerce store and software company have completely different economics.
Instead of chasing an arbitrary percentage, compare your margin with:
your historical performance;
your pricing model;
your direct competitors where reliable data exists;
your operating requirements;
your return on the capital and labour involved.
A sustainable 15% margin in one industry may represent a strong business, while the same margin in another may be disappointing.
5. If my sales increase, should my profit always increase?
Not automatically.
Profit can fall while revenue rises if the business experiences:
higher advertising costs;
discounting;
lower-margin products;
additional staff;
higher delivery costs;
wastage;
returns;
inefficient expansion;
increased overheads.
Monitor both the rand value of profit and the profit margin.
If revenue rises rapidly while margin consistently declines, investigate why.
6. At R100,000 monthly turnover, must I register for VAT?
Not simply because one month reaches R100,000.
From 1 April 2026, South Africa’s compulsory VAT-registration threshold increased to R2.3 million, subject to the relevant taxable-supply and registration rules. The voluntary-registration threshold increased to R120,000. (South African Revenue Service)
R100,000 monthly annualised is R1.2 million, which is below the current R2.3 million compulsory threshold.
However, VAT circumstances can become more complicated than a simple monthly calculation, so businesses approaching relevant thresholds should verify their position directly with SARS or a qualified tax practitioner.
7. Should I withdraw all the profit from my business?
Not automatically.
Your business may need money for:
working capital;
tax;
emergencies;
future stock;
equipment;
growth;
slow-paying customers.
A profitable business with no cash reserve can still become financially vulnerable.
How much you should withdraw also depends on whether you’re operating as a sole proprietor, company or another structure and how the payment is legally and tax-wise classified.
Final Example: Follow One R100,000 Month From Beginning to End
Let’s finish with a complete simplified example.
A small South African online business generates:
R100,000 sales.
Cost of products:
−R40,000
Gross profit:
R60,000.
Advertising:
−R10,000
Delivery:
−R6,000
Staff:
−R8,000
Payment/banking costs:
−R2,000
Software:
−R2,000
Other operating expenses:
−R4,000
Operating profit:
R28,000
Operating margin:
28%
Now the owner considers:
tax provisions;
next month’s stock requirements;
business reserves;
owner compensation.
Perhaps only R15,000–R20,000 is sensible to take personally at that point.
Perhaps more is affordable.
Perhaps less.
The answer depends on cash flow and the business’s obligations.
But one thing is certain:
The owner did not personally make R100,000.
Conclusion: Stop Asking “How Much Did I Sell?”
Reaching R100,000 in monthly sales is worth celebrating.
For many entrepreneurs, it represents months or years of risk, long hours, failed ideas, customer complaints, advertising experiments and persistence.
But don’t stop your analysis at the sales figure.
Ask the next question:
“What did it cost me to generate that R100,000?”
Then:
“What did it cost to run the business?”
Then:
“What profit actually remained?”
And finally:
“How much of that profit became usable cash?”
Those questions transform the way you see your business.
A R100,000 sales month might produce R60,000 of operating profit in one business.
It might produce R15,000 in another.
It might produce nothing in a badly priced operation.
That’s why the entrepreneur chasing profitable sales is playing a different game from the entrepreneur chasing sales alone.
Turnover can make a business look impressive.
Margin shows how well its economics work.
Cash keeps it alive.
And sustainable profit is what eventually allows the business to reward its owner, employ people, survive difficult periods and grow.
So celebrate R100,000 in sales.
Then open the books.
The number that matters most may be the one left at the bottom.
