Margin vs markup — what's the difference? Margin is profit as a share of your selling price. Markup is profit as a share of your cost. A ₦500 profit on a ₦1,000 sale is a 50% margin but a 100% markup — same money, two different numbers. Lenders and accountants usually mean margin.

How to calculate profit margin

Profit margin tells you how much of every naira you keep as profit. The formula is simple:

Profit = Selling Price − Cost Price
Margin % = (Profit ÷ Selling Price) × 100

For example, if you buy an item for ₦700 and sell it for ₦1,000, your profit is ₦300 and your margin is 30%. This calculator does it for you instantly — and can also work backwards to tell you what to charge for a target margin.

Margin vs markup — don't confuse them

Many business owners mix these up and underprice by accident. Markup is your profit measured against what the item cost you. Margin is your profit measured against what you sold it for. A 100% markup is only a 50% margin. Always know which one you mean when you set prices.

What is a good profit margin for a Nigerian business?

It depends on your trade. Fast-moving groceries and provisions often run on thin margins (5–15%) but high volume, while fashion, electronics accessories, and cosmetics can carry higher margins (30–60%). The key is knowing your real margin on each product so you never sell at a loss — and adjusting prices as your costs change.
