How to Work Out Your Real Profit per Product in a Nigerian Shop

You stand behind your counter, busy from morning till night. Customers are buying, money is coming in. You feel good. But do you *really* know how much profit each item is bringing into your pocket? Many traders in Nigeria just look at the selling price minus the buying price and say, "Okay, this is my profit." But that’s like looking at the rain and saying the sky is wet. It’s true, but it’s not the whole story.

Your true profit is what’s left after you pay for everything that helped you sell that item. This means not just the cost of buying the goods, but also the cost of getting them to your shop, the rent for your stall, the electricity bill, maybe the salary for that assistant you hired, and even the small amounts you spend on recharge cards for your business phone. If you don't count all these things, you might be selling some items that look popular but are actually costing you money.

How to Know What Each Item Truly Costs You

To find your real profit per product, you must first know the total cost of selling that product. Think of it like this: if you sell 10 bags of rice, the cost of getting those 10 bags to your shop is part of the cost of selling each bag. The same for your stall rent for the month – you can divide that rent by the number of items you expect to sell to find out how much each item carries. This is where many traders get it wrong. They only look at the direct cost of the goods.

Here’s how to break it down:

• Direct Cost: This is the price you paid to buy the product from your supplier. If you sell recharge cards, this is the amount you paid to buy the airtime. If you sell fabrics, it’s the cost per yard you bought it at.
• Indirect Costs (Overheads): These are the costs of running your business that are not tied to one specific product but are necessary for sales to happen. This includes:
  • Rent: Your shop or stall rent.
  • Utilities: NEPA bills, generator fuel, water.
  • Transportation: Cost to go buy goods, cost to bring goods to your shop.
  • Salaries: If you have staff.
  • Marketing: Money spent on adverts or promoting your business.
  • Supplies: Bags, receipts, stationery, phone credit for business calls.
  • Bank Charges/Transaction Fees: Fees from POS transactions or transfers.

To find the true cost of a product, you need to add a portion of these indirect costs to the direct cost of each item. For example, if your total indirect costs for a month are ₦50,000, and you expect to sell 1,000 items in that month, then each item carries ₦50 of your overhead costs (50,000 / 1,000). If you bought that item for ₦200, its total cost to you is actually ₦250 (200 + 50).

How to Calculate Profit Per Product

Once you know your total cost per product (direct cost + allocated indirect cost), calculating profit is simple:

Profit Per Product = Selling Price - Total Cost Per Product

Let’s use an example. Amina sells Ankara fabrics in Balogun Market. She buys a Ankara fabric roll for ₦15,000. She cuts it into 10 smaller pieces to sell. So, the direct cost per piece is ₦1,500 (15,000 / 10).

Her monthly expenses (rent, transport, electricity, etc.) add up to ₦40,000. In a month, she usually sells about 50 Ankara fabric rolls. This means each roll carries about ₦800 in overhead costs (40,000 / 50). So, the total cost for one piece of fabric is ₦1,500 (direct cost) + ₦800 (overhead) = ₦2,300.

Amina sells each piece of fabric for ₦3,500. Her profit per piece is ₦3,500 (selling price) - ₦2,300 (total cost) = ₦1,200.

If Amina was just looking at direct cost, she would think her profit is ₦3,500 - ₦1,500 = ₦2,000. But by including her overheads, she sees her real profit is ₦1,200. This is crucial because if her rent suddenly doubles, or if she sells fewer rolls, her overhead per piece will increase, and her actual profit will drop, even if she sells at the same price.

This is why keeping good records is so important. If you are recording your sales accurately, and also your expenses, you can easily calculate this. Tools like the free daily takings and debt calculator can help you start tracking, but for a full picture, you need something more.

Why Knowing Profit Per Item Matters More Than You Think

Understanding your profit per product helps you make smarter business decisions:

• Pricing Strategy: You can see which products have the highest profit margin and adjust your prices accordingly. Maybe you can slightly lower the price of a very high-margin item to sell more, or increase the price of an item with a slim margin if demand is high.
• Stock Management: Focus your capital on products that give you the best return. If you see that product X gives you ₦500 profit while product Y gives you only ₦100 profit, and they sell at similar rates, you should consider stocking more of product X. This is the heart of smart stock and inventory management.
• Identifying Loss Leaders: Sometimes, a business might sell one item at a very low profit or even a loss (a loss leader) to attract customers who then buy other, more profitable items. Knowing your profit per item helps you identify if you are doing this intentionally and if it's working, or if you are just losing money on popular items without getting enough compensating sales elsewhere.
• Business Performance: You can tell which parts of your business are truly making money and which are draining your resources. This is key to understanding why your shop feels busy but the drawer is empty.

The Challenge of Manual Record Keeping

For most traders, calculating profit per item means writing down every single purchase, every expense, and every sale. This is difficult and time-consuming, especially when you are busy serving customers. Who has the time to divide their ₦60,000 monthly rent by the 2,000 sachets of sugar they sold last month while a customer is waiting to pay?

And if you sell many different products, trying to track the specific cost and profit for each one manually can be a nightmare. You might get it wrong, or you might just skip it altogether. This is why many traders don't really know their profit per item, or even their overall profit. They rely on their gut feeling, which can be misleading.

This is where tools that simplify record-keeping come in. Imagine if collecting payment automatically recorded the sale and started tracking your costs. That's the idea behind TrustAm's WhatsApp Business Assistant. When you receive a payment, the sale is recorded. When you record an expense by voice note or taking a photo of a receipt, it gets logged. At the end of the day, you get a summary. This makes it much easier to know your numbers and calculate profit per product without the headache.

With TrustAm, you can get a daily summary of your sales and expenses, and over time, it builds up a picture of your business performance. You can see how much money came in, how much went out, and importantly, what profit you made. This allows you to track things like sales and expenses more effectively, which is a core part of good business record keeping.
