Why profit margin matters to a first-time founder
Margin shows how much room the business has to absorb mistakes, invest and survive slower sales. Tracking only revenue can hide a model that loses money as it grows. Comparing margins over time also exposes pricing pressure, rising costs or a product mix that is becoming less sustainable.
Examples of profit margin
A studio earns ₦100 million in revenue and records ₦12 million of net profit after all expenses and tax. Its net profit margin is 12%: ₦12 million divided by ₦100 million. If revenue rises to ₦120 million but profit stays at ₦12 million, the margin falls to 10%.
Common misunderstanding
Profit margin is not the same as markup. Margin divides profit by the selling price or revenue, while markup divides profit by cost. “Profit margin” also needs a qualifier: gross, operating and net margins subtract different costs, so figures are not comparable unless they use the same level.
When to use it
Use the relevant margin when setting prices, forecasting cash needs or comparing similar products and businesses. Review the trend and the calculation behind it, not just one percentage. Ignore broad industry benchmarks when accounting policies, business models or growth stages differ enough to make the comparison misleading.
