profit margin: calculation and interpretation

Profit Margin: Calculation & Interpretation
📊 The profit margin tells you how much of every dollar of sales a company keeps as profit. Think of it like a pizza: if you sell a pizza for $10 and keep $2 after paying for ingredients, your profit margin is 20 %.
Formula
Profit margin is calculated with the following formula:
$Profit\ Margin = \frac{Net\ Profit}{Revenue} \times 100\%$
Step‑by‑Step Example
Company X – 2023 Financials
| Item | Amount (£) |
|---|---|
| Revenue | 1,200,000 |
| Net Profit | 180,000 |
| Profit Margin | $\frac{180,000}{1,200,000} \times 100\% = 15\%$ |
Interpretation
📈 A 15 % profit margin means that for every £1 sold, the company keeps £0.15 as profit. Higher margins usually indicate better cost control or a premium product. However, compare with industry peers – a 15 % margin in a low‑margin sector (e.g., supermarkets) is great, but in a high‑margin sector (e.g., software) it might be low.
Key Points to Remember
- Profit margin = Net profit ÷ Revenue.
- Expressed as a percentage.

- Compare across time and competitors.
- Watch for changes in cost structure that affect the margin.
