How the formula works
Profit = revenue minus variable costs minus fixed costs. Revenue is price times units sold. Variable costs move with each unit; fixed costs such as rent and salaries do not. Margin is profit divided by revenue, which is the cleanest single indicator of pricing health.
Worked example
A bakery sells 120 loaves at Rs. 150. Flour and energy cost Rs. 60 per loaf, rent and staff cost Rs. 6,000 per month. Revenue is Rs. 18,000, variable costs are Rs. 7,200, fixed costs are Rs. 6,000, so profit is Rs. 4,800 and margin is about 26.7 percent.
What affects the result
Profitability depends on three levers: price, volume, and the split between variable and fixed costs. Raising price lifts margin on every unit but can cut demand; cutting variable costs improves margin with no volume risk; volume spreads fixed costs over more units. A healthy business usually shows stable gross margin with operating and net margins that improve as it scales.
Common mistakes
- Counting your own salary as profit instead of as a fixed cost.
- Using best-month sales as the normal month when estimating volume.
- Forgetting payment processing fees, which are variable costs on every sale.
- Comparing margin percentages across businesses with very different capital needs.
Frequently asked questions
Is margin or profit more important?
Profit pays bills; margin shows efficiency. A low-margin business can earn a lot at scale but has little room for error, so track both.
What counts as a variable cost?
Anything that rises or falls directly with each unit sold: materials, packaging, delivery, payment fees, commissions.
Should taxes be included here?
This calculator shows pre-tax operating profit. Use the tax calculator for an after-tax estimate.
How can I estimate how much a company is making?
Start on a per-unit basis: price times estimated volume gives revenue, then subtract variable and fixed costs to reach profit. For a company you cannot inspect directly, triangulate across pricing, public benchmarks, employee counts and unit economics. See the guide on estimating a company's revenue for the full method.
