Profitability Formulas
Profitability formulas answer different questions. Use a consistent revenue period and cost definition before comparing results across products, teams or time periods.
Profit MarginCalculate gross profit, gross margin, and markup from sales revenue and direct cost.Operating MarginCalculate operating profit and operating margin after direct costs and operating expenses.Net Profit MarginCalculate net profit and net margin after direct costs, operating expenses, interest, and taxes.MarkupFind a selling price and gross profit from product cost and a chosen markup percentage.Break-EvenCalculate the unit sales and revenue needed to cover fixed and variable costs.
Use these formulas consistently
Separate margin from markup
Margin divides profit by revenue, while markup divides price increase by cost. The percentages are not interchangeable.
Keep cost boundaries consistent
Gross, operating and net profit include different expense layers. Label each input so a period-to-period comparison uses the same boundary.
Test more than one scenario
Volume, price and cost can move together. Compare a base, downside and upside case rather than relying on one estimate.
