How to calculate your real business profit: a simple daily method for Nigerian traders
· 5 min read
Ask most traders how the business is doing and you will hear a number from the cash box: "I made ₦60,000 today." But that number mixes together money that belongs to your suppliers, money customers have not paid yet, and money you will spend tomorrow on transport and restocking. It feels like profit. Usually it is not.
Knowing your real profit is what tells you whether to raise prices, which products to stock more of, whether you can afford a shop assistant, and whether the business can repay a loan. The good news: you do not need to be an accountant. You need three numbers and ten minutes a day.
The three numbers that matter
1. Sales (revenue) — everything you sold, whether the customer paid in cash, by transfer, by POS, or took the goods on credit.
2. Gross profit — sales minus what those goods cost you to buy. If you sold a bag of rice for ₦78,000 that you bought for ₦70,000, your gross profit on that bag is ₦8,000.
3. Net profit — gross profit minus the costs of running the business: transport, shop rent, market levies, POS and transfer charges, data, electricity or fuel, staff pay, and anything that spoiled or went missing.
Net profit is the money the business actually earned. It is the only number that tells you whether you are growing or slowly eating your capital.
A worked example
Here is a day in an illustrative provisions shop (the figures are an example, not data from a real business):
| Amount | |
|---|---|
| Sales — cash, transfer and POS | ₦71,000 |
| Sales — goods taken on credit | ₦14,000 |
| Total sales | ₦85,000 |
| Cost of the goods sold | ₦62,000 |
| Gross profit | ₦23,000 |
| Transport to market | ₦3,500 |
| Shop assistant's daily pay | ₦2,000 |
| POS and transfer charges | ₦600 |
| Market levy | ₦500 |
| Net profit | ₦16,400 |
Notice two things. First, the cash box would have shown ₦71,000 — more than four times the real profit. Second, ₦14,000 of the "sales" has not been paid yet. Until it is, that money is a promise, not cash you can spend.
Five mistakes that hide your true profit
1. Counting cash instead of recording sales
Cash counts miss transfers and POS payments, and they include money that is not from sales at all — a loan from a friend, change you started the day with. Record each sale when it happens, with how it was paid.
2. Restocking with sales money and forgetting the cost
If you sell ₦85,000 and spend ₦62,000 restocking the next morning, it is easy to feel you are always short of money. You are not short — most of that money was never profit. Track the cost of what you sell so you know your margin on each item.
3. Mixing personal and business money
School fees, family support and food from the shop's stock all come out of the same drawer in many businesses. That makes profit impossible to see. Pay yourself a fixed amount each week or month, and treat anything else you take as a withdrawal — not a business expense.
4. Treating credit sales as money in hand
Selling on credit is normal in Nigerian trade, and it keeps good customers loyal. But every naira on credit is money you cannot use to restock. Write down who owes you, how much and since when, and follow up before the debt gets old. Debt that is never collected was never profit.
5. Ignoring the small leaks
₦100 here in transfer charges, ₦500 there on data or a levy, a few tomatoes that spoiled. Small costs, repeated every day, can add up to a large share of a month's profit. Record every expense, however small.
A ten-minute daily routine
You can do this in a notebook, a spreadsheet or an app — what matters is doing it every day.
- Record every sale as it happens — item, quantity, price, and how the customer paid (cash, transfer, POS or credit).
- Record every expense as it happens — what it was for and how much.
- Note credit given and credit repaid — customer name and amount.
- At closing time, total the day — sales, cost of goods, expenses, and the profit that is left.
- Once a week, count your stock — so you can see what is selling, what is not moving, and whether anything is missing.
At the end of the month, add up the weeks. Now you can compare one month with the next, see which products earn the most per item, and make decisions from numbers instead of feelings.
When the notebook stops working
A notebook is fine when you run one stall alone. It starts to break down when you have staff serving customers, more than one branch, many customers buying on credit, or when a bank asks you for six months of records. That is usually the moment to move your records onto your phone.
How KudiAI Track helps
KudiAI Track, our money-management app for traders and small businesses, is built around exactly this routine:
- Sales and expenses recorded in seconds, so profit is a number, not a guess.
- Debt tracking for customers who buy on credit, with repayments logged and statements you can share.
- Inventory that shows what is running low and what is not moving.
- Financial reports — profit and loss, cash flow and period summaries you can export.
- A voice assistant that lets you record transactions and ask questions about your business by speaking.
