Degree of Operating Leverage Calculator
Divide total contribution margin by operating profit. With 200,000,000 of contribution against 150,000,000 of fixed costs, profit is 50,000,000 and the degree is 4.0. Sales up 10% lifts operating profit 40%; sales down 10% takes 40% off. Heavier fixed costs raise the multiple, because near break-even the denominator thins out and the ratio runs away to infinity.

Formula
Degree of operating leverage = Total contribution ÷ (Total contribution − Fixed costs)
The multiple works in both directions — four times the gain in a good year is four times the loss in a bad one. The contribution you enter is the period total (revenue less variable costs), not the per-unit figure; enter per-unit and the multiple comes out absurdly small. Below break-even the denominator is negative and the ratio cannot be read, so this shows zero.

Frequently asked questions
Q. How is Degree of Operating Leverage Calculator calculated?
Degree of operating leverage = Total contribution ÷ (Total contribution − Fixed costs) — Divide total contribution margin by operating profit. With 200,000,000 of contribution against 150,000,000 of fixed costs, profit is 50,000,000 and the degree is 4.0. Sales up 10% lifts operating profit 40%; sales down 10% takes 40% off. Heavier fixed costs raise the multiple, because near break-even the denominator thins out and the ratio runs away to infinity.
Q. Can you walk through an example?
With Total contribution 200,000,000, Fixed costs 150,000,000, Change in sales 10%, the answer is Degree of operating leverage 4×.
Q. What do I need to enter?
Enter Total contribution, Fixed costs, Change in sales. The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only Total contribution moves the answer to Total contribution 100,000,000 → Degree of operating leverage (×) 0 and Total contribution 400,000,000 → Degree of operating leverage (×) 1.6. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
Q. Anything to watch out for?
The multiple works in both directions — four times the gain in a good year is four times the loss in a bad one. The contribution you enter is the period total (revenue less variable costs), not the per-unit figure; enter per-unit and the multiple comes out absurdly small. Below break-even the denominator is negative and the ratio cannot be read, so this shows zero.
