How to Price Your Products: A Profit Margin Guide for African Sellers

To learn how to price products for profit, add up every cost of getting one item to the customer, decide the profit you need on each sale, and set a price that covers both with some room for discounts and currency changes. The most common reason small sellers lose money is not slow sales. It is a price that ignores some costs. This guide explains cost price and selling price, the difference between profit margin and markup, a simple pricing formula for sellers, and how to set separate prices for wholesale and retail. All numbers in the examples are illustrative round figures, not real market prices.

Start with your true cost price

Your cost price (the starting point for any cost price and selling price calculation) is not just what you paid your supplier. It is everything you spend to have one unit ready to hand over. Include:

The purchase price per unit.
Transport from the supplier to you, shared across the units in the load.
Import duties, clearing and handling fees if you import.
Packaging: bags, boxes, tape, labels, bubble wrap.
Payment charges, such as bank or card fees.
Delivery you pay for, if you offer free delivery.
A share of fixed costs: shop rent, phone data, electricity, staff pay, social media tools.
An allowance for items that break, expire or are returned.

Many sellers forget the last two groups. If you buy 100 units and 5 spoil, the other 95 must pay for all 100. Divide your total spending by the units you can actually sell, not by the units you bought.

Profit margin vs markup: do not mix them up

These two terms sound similar, yet they give different results, and confusing them is a classic pricing error.

Markup is profit as a percentage of your cost. If an item costs ₦1,000 and you sell for ₦1,300, your markup is 30% (₦300 divided by ₦1,000).
Profit margin is profit as a percentage of your selling price. On the same sale, your margin is about 23% (₦300 divided by ₦1,300).

So a 30% markup is not a 30% margin. If you want a 30% margin and you only add a 30% markup, you will earn less than you planned. Decide which one you use, and use it consistently, especially when you talk to partners or lenders. A simple rule is to track margin, because it tells you how much of each naira you receive stays with you.

A pricing formula for sellers that you can use today

Here are two formulas. Pick one and stick to it.

Using markup

Selling price = total cost per unit multiplied by (1 + markup percentage). Example: cost ₦2,000, markup 40%. Selling price = ₦2,000 x 1.40 = ₦2,800.

Using target margin

Selling price = total cost per unit divided by (1 minus target margin). Example: cost ₦2,000, target margin 30%. Selling price = ₦2,000 / 0.70, which is about ₦2,857.

Notice that the margin formula gives a slightly higher price for a similar-looking percentage. That is why the two are different.

A worked example (illustrative)

Imagine a seller buys 50 pieces of a small kitchen item. These are made-up numbers.

Purchase: 50 x ₦1,500 = ₦75,000
Transport: ₦5,000
Packaging: 50 x ₦100 = ₦5,000
Payment charges and data: ₦2,500
Total spent: ₦87,500
Expected losses: 2 pieces may be damaged, so sellable units = 48
True cost per sellable unit: ₦87,500 / 48, about ₦1,823

If the seller had used only the supplier price of ₦1,500 and sold at ₦1,800, they would believe they earned ₦300 profit per item. In reality they lose a little on each sale. With a 30% target margin, the price would be ₦1,823 / 0.70, roughly ₦2,604. That is a very different number from ₦1,800. Always run the full calculation before you list a price.

Check what the market will accept

Your cost sets the lowest sensible price. The market sets the highest. Look at similar items on marketplaces, in shops and on social media. Compare quality, brand, warranty and delivery. The Comilmart price guide can help you see how products are commonly presented. If your calculated price is far above the market, you can improve your cost (buy in larger lots, find a better supplier, reduce packaging waste), offer something extra (fast replies, a better box, a short care card), or choose a different product. Do not simply cut your price below cost to win a sale.

Set prices for wholesale and retail

Setting a price for wholesale and retail separately keeps both groups of buyers fair and your profit protected.

Selling a single item to a household and selling a carton to a shop are different jobs, so they need different prices. Wholesale buyers purchase in bulk and expect a lower unit price because you spend less time, packaging and delivery per unit. Retail buyers pay more per unit because you carry the storage and handling.

A simple structure many sellers use:

Retail: your full price, one or a few units.
Small wholesale: a modest discount for a set minimum quantity, such as a dozen.
Large wholesale: a larger discount for a bigger minimum quantity.

Before you offer any discount, check that your margin on the lowest tier is still above zero after all costs. If you plan to sell in volume as a producer, our article on tiered wholesale pricing strategy for manufacturers goes deeper into minimum order quantities and tier design. State your minimum order quantity clearly in every listing so buyers know which price applies.

Handle discounts and promotions carefully

A discount is not free marketing. It comes straight out of your profit. Use this check before any promotion: new price minus total cost equals what you earn per unit; then multiply by the number of extra units you expect to sell. If the discounted price leaves you only a few naira per item, you may need a large jump in sales just to break even. Better ideas include bundles (two items for a small saving), free small gifts that cost you little, early-bird offers with a clear end date, and clearing slow stock at a planned price rather than panic selling.

Plan for exchange rate and cost changes

If you import goods or sell items made with imported materials, your costs can change when the exchange rate or fuel prices move. A price that was safe last month may cause a loss this month. Practical habits:

Recalculate your cost each time you restock, not once a year.
Add a small buffer for currency movement on imported items.
Keep price lists short-dated, such as valid for seven days or until stock changes.
Avoid promising a fixed price on goods you have not yet bought.

If you sell to buyers abroad or price in foreign currency, read our guide on currency risk and pricing for African exporters and manufacturers.

How to avoid selling at a loss

Keep a cost sheet for every product, updated whenever your supplier price changes.
Set a minimum price below which you never go, even when a buyer bargains hard.
Count delivery and payment fees on every order, especially small ones.
Review your numbers weekly: total sales, total costs, money left.
Remove products that sell but earn almost nothing, or raise their price.

Frequently asked questions

What is a good profit margin for a small seller? There is no single right number. It varies by product, competition and how much work each sale needs. Work out your own costs and the margin you need to stay in business, then check it against what the market accepts.

Should I match my competitor's price? Not automatically. They may have lower costs, different quality or be willing to lose money. Know your own floor price first.

Should I include delivery in the price? You can either charge delivery separately or build an average delivery cost into the price. Whichever you choose, make it clear before payment so there are no surprises.

How often should I change prices? Review them whenever your cost changes, and at least monthly. Tell regular customers politely when a price must rise.

Is it better to have a higher price or higher sales volume? Both can work. Compare total profit, not just sales count. A higher price with fewer sales can earn more than a low price with many sales, once you include time and packaging.

Do I need accounting software? Not at the start. A notebook or spreadsheet with cost, price, quantity sold and expenses is enough for most small sellers. This is general information, not financial advice.
