How to Know My Business Profit in Nigeria, Kenya and Ghana

How to calculate net profit for your shop

To know your business profit, subtract your total operating expenses from your total revenue over a specific period. You must ensure you are only counting money earned from sales and subtracting the actual costs of running the business, including stock replacement and overheads.

Step 1: Track all daily sales

Every single transaction must be recorded. Whether you are running a kiosk in Nairobi, a market stall in Accra, or a supermarket in Lagos, you need a daily record of every Naira, Cedi, or Shilling that enters your till. Do not rely on your memory. If you sell a bag of rice or a crate of soft drinks, write it down immediately.

Step 2: Calculate your Cost of Goods Sold (COGS)

Your profit is not just the cash in your drawer at the end of the day. You first have to pay for the stock you sold. Calculate your COGS by adding your starting inventory to your purchases, then subtracting your ending inventory. If you bought 100 cartons of soap for 100,000 NGN and sold 80 of them, your COGS is the value of those 80 cartons.

Step 3: List all your operating expenses

Operating expenses are the costs required to keep your doors open. In Africa, these often include shop rent, electricity or generator fuel costs, staff salaries, transport to the wholesale market, and mobile money or POS transaction fees. Create a monthly list of these items to see what is draining your cash.

Step 4: Subtract expenses from gross profit

Once you have your total sales and your COGS, subtract the COGS from the total sales to get your Gross Profit. After that, subtract your operating expenses from the Gross Profit to arrive at your Net Profit. This is the true measure of whether your business is making money or just moving cash around.

For example: Calculating monthly profit

Imagine you own a small provisions store. In one month, you sold goods worth 500,000 KES. You paid 350,000 KES to your suppliers for the stock you sold (COGS). This leaves you with a Gross Profit of 150,000 KES. Now, you deduct your operating costs: 30,000 KES for rent, 10,000 KES for electricity, and 20,000 KES for a shop assistant. Your total expenses are 60,000 KES. Subtracting 60,000 KES from your 150,000 KES Gross Profit leaves you with a Net Profit of 90,000 KES.

What are the common mistakes when tracking profit?

Many shop owners in Nigeria, Kenya, and Ghana fall into traps that make their business look more profitable than it actually is. Avoiding these will save you from future financial stress.

Mixing personal and business money: If you take cash from the till to pay for family school fees or household food, you are losing track of your actual profit. Always pay yourself a fixed, separate salary.
Ignoring stock spoilage: If food items go bad or goods get damaged, they represent lost money. You must account for this as an expense, or your profit figures will be wrong.
Forgetting small expenses: Small daily costs like buying data, paying for transport to the market, or buying cleaning supplies add up. If you do not record them, you will wonder where your profit went at the end of the month.
Using revenue as profit: Assuming all the cash you collect is profit is the fastest way to bankrupt a shop. Always remember that a large portion of that cash belongs to your suppliers.

How to spot profit problems early

If you find that your bank account or cash box is shrinking despite having steady sales, you have a leak. Start by reviewing your inventory logs against your sales records. If the stock is missing but no cash was recorded, you have an issue with internal theft or recording errors. Secondly, compare your monthly electricity and fuel costs; if they are rising without a corresponding rise in sales, investigate your energy consumption patterns. Lastly, review your supplier prices. If your COGS is increasing but you haven't raised your shelf prices, your profit margin will slowly disappear.

Use tools to simplify the process

Keeping manual records in notebooks is common, but it leaves room for calculation errors and lost pages. Using a digital system can help you stay organized.

What is the next step I should take?

Your immediate next step is to perform a "stock take" today. Count every item currently on your shelves and compare it to the records of what you have bought and what you have sold. If the numbers do not match, identify why. Once you have a clear picture of your actual stock, commit to recording every single sale and every single expense in a dedicated ledger or digital tool starting tomorrow morning.
