Most business owners know they’re supposed to care about profit. What fewer of them know is that there are two very different numbers that both get called “profit” — and confusing them is one of the most common reasons a business owner thinks they’re doing well when they’re actually not.
Let’s sort this out once and for all.
What These Words Actually Mean
Forget the textbook definitions for a moment. Let’s use a corner café.
Thabo runs a café. On a good Saturday, he takes in R10,000 in sales — coffee, sandwiches, slices of cake.
To make those coffees and sandwiches, he spent R3,500 on ingredients, milk, coffee beans, and packaging. That’s it. Just the stuff that went directly into what he sold.
Gross profit = what’s left after paying for what you sold
R10,000 − R3,500 = R6,500 gross profit
That R6,500 looks great. But Thabo still has to pay rent on the café. He has to pay his two staff members. He pays for electricity, his internet, his card machine fees, his accountant, and his insurance. After all of that:
Net profit = what’s left after paying for everything
R6,500 − R5,800 in operating costs = R700 net profit
Thabo made R10,000 in sales. He walked away with R700.
That’s the difference between gross profit and net profit. One tells you how well you’re selling. The other tells you how well you’re actually running a business.
Why This Matters for Your Business
Here’s the mistake we see constantly.
A business owner looks at their gross profit and feels good. The margins on what they sell look healthy. They’re charging the right prices. Life is good.
Then month end arrives and there’s nothing left in the account.
Why? Because gross profit doesn’t account for rent. It doesn’t account for staff. It doesn’t account for the software subscriptions, the fuel, the marketing spend, the accountant’s fees, or the SARS payment that’s due. All of those costs live between gross profit and net profit — and if you’re only watching gross profit, you’re only seeing half the picture.
Gross profit answers: Am I pricing correctly? If your gross profit margin is thin — you’re not charging enough for what you sell, or your direct costs are too high. This is a pricing and product problem.
Net profit answers: Is my business actually sustainable? If your gross profit is healthy but your net profit is tiny or negative, your overheads are eating you alive. This is an expenses and structure problem.
Two very different problems. Two very different solutions. You can’t tell which one you have if you’re only looking at one number.
The South African Reality
Here’s something worth saying plainly.
Many small business owners in South Africa run their businesses from their bank account balance. If there’s money in the account, things are fine. If there isn’t, things are not.
The problem with this approach is that your bank balance doesn’t tell you why. It doesn’t separate the money that came in from sales, the money that went out on direct costs, and the money that went out on overheads. It doesn’t show you whether your pricing is healthy or whether your rent is killing you.
Gross profit and net profit are the two numbers that start to give you that picture. They’re not complicated. They’re just two checkpoints on the journey from “money came in” to “money is actually mine.”
What To Do With This
Find your gross profit
Take your total sales for the month. Subtract only the costs that went directly into making what you sold — stock, materials, direct labour if applicable. That number is your gross profit.
Find your net profit
Take your gross profit. Subtract everything else — rent, salaries, software, marketing, insurance, fuel, professional fees, bank charges. What’s left is your net profit.
Look at both every month
If your gross profit margin is shrinking, look at your pricing and your direct costs. If your net profit is shrinking despite a healthy gross profit, look at your overheads. Each number is pointing at a different part of your business.
Keep It Simple
- Gross profit= sales minus the direct cost of what you sold. Tells you if your pricing is right.
- Net profit= gross profit minus all your other business costs. Tells you if your business is actually making money.
- A healthy gross profit with a weak net profit means your overheads are the problem — not your pricing
- Running your business from your bank balance means you can’t see which problem you actually have
- Ask your accountant to show you both numbers every month — it takes five minutes and changes how you see your business
Knowing the difference between these two numbers won’t make your business profitable on its own. But not knowing the difference makes it almost impossible to fix what’s actually wrong.
