The Core Difference in One Line
Markup = Profit ÷ Cost × 100
The key insight: margin uses the selling price as its base; markup uses the cost as its base. For the same product, markup will always produce a higher percentage than margin when profit is positive.
Worked Example in Naira
A Lagos trader buys a bag of rice for ₦45,000 and sells it for ₦60,000.
- Profit = ₦60,000 − ₦45,000 = ₦15,000
- Profit Margin = ₦15,000 ÷ ₦60,000 × 100 = 25%
- Markup = ₦15,000 ÷ ₦45,000 × 100 = 33.3%
Same transaction. Same naira profit. Two very different percentages: 25% margin vs. 33.3% markup.
Which Should You Use?
| Use Margin When… | Use Markup When… |
|---|---|
| Reporting financial performance to investors or accountants | Setting the selling price from a known cost |
| Comparing profitability across product categories | Standardising how a distributor or retailer adds value |
| Benchmarking against industry profit margin averages | Pricing goods consistently across a catalogue |
| Monitoring gross margin trends over time | Communicating how much is added to wholesale cost |
Converting Between Margin and Markup
You can convert between the two using these formulas:
Margin from Markup: Margin% = Markup% ÷ (1 + Markup%)
Example: If your margin is 25%:
Markup = 0.25 ÷ (1 − 0.25) = 0.25 ÷ 0.75 = 33.3% ✓
Gross Margin vs. Net Margin
In accounting, "profit margin" may refer to different levels of profit:
- Gross Margin: (Revenue − Cost of Goods Sold) ÷ Revenue. Does not include operating expenses like rent, salaries, marketing.
- Operating Margin: Also deducts operating expenses (OPEX). Shows the business's efficiency.
- Net Margin: Deducts everything including taxes and interest. The bottom-line percentage.
When business owners say "my margin is 30%," they are usually referring to gross margin - the percentage after subtracting the direct cost of the product, but before overhead.
Typical Nigerian Sector Benchmarks
- Food retail / supermarkets: Gross margin 10–25%
- Fashion / clothing: Gross margin 40–60%
- Electronics trading: Gross margin 8–18%
- Restaurant / food service: Gross margin 60–70% (food cost is low, overhead is high)
- Building materials: Gross margin 15–30%
- Pharmaceutical retail: Gross margin 20–35%
Common Pricing Mistakes
- Quoting margin% when the buyer expects markup%: A supplier who quotes "30% margin" and a buyer who hears "30% markup" will calculate completely different selling prices.
- Using gross margin to claim net profit: If your gross margin is 40% but overhead costs 35% of revenue, your net margin is only 5%.
- Setting price on cost + flat % without checking the market: A 100% markup on a product the market only accepts at 60% above cost will leave goods unsold.
- Ignoring VAT in your margin calculation: If you are VAT-registered in Nigeria, the 7.5% VAT collected is not revenue - it belongs to FIRS. Always strip it out before calculating margin.
