Profit sensitivity to sales changes. The Operating Leverage Calculator takes revenue, variable costs, fixed costs and returns degree of operating leverage plus contribution margin, operating profit, profit change for a 10% rise in sales. Results update as you type, and the formula is shown under the result so you can repeat it in your own spreadsheet.
Financial ratios are only useful in comparison: against last year, against a competitor, or against the benchmark for your industry. Take the figures from the same set of accounts, note whether they are yearly or monthly, and read each ratio alongside the others in its family. Use the worked example below to check the maths against your own figures.
How the Operating Leverage Calculator works
Operating leverage tells you how much operating profit moves for a given change in sales. A DOL of 2.5 means a 10% rise in sales lifts profit 25%, and a 10% fall cuts it 25%: high fixed costs make profit volatile.
Worked example
With the example values (revenue of $1,000,000, variable costs of $600,000, fixed costs of $250,000), the degree of operating leverage is 2.67x; contribution margin $400,000.00, operating profit $150,000.00, profit change for a 10% rise in sales 26.67%. Change any figure above and the result updates immediately; use Copy results to paste the summary into a note or email.

Frequently Asked Questions
How is degree of operating leverage calculated?
degree of operating leverage = contribution margin ÷ operating profit.
Which figures do I need?
Revenue, variable costs, fixed costs. Take them from the same period and the same set of accounts or reports so the ratio is consistent, and check the example values as a guide to the units expected.
What is a good value for this ratio?
Benchmarks differ by industry, size and business model, so compare with companies like yours and with your own history. A ratio moving in the wrong direction for several periods matters more than any single number.
