How to Read Your Results
Contribution margin is the currency amount left after variable costs, not final profit.
The contribution margin ratio shows the share of each sales dollar that can cover fixed costs and profit.
Positive estimated operating income means contribution margin exceeds the fixed costs entered.
Break-even revenue is a planning estimate based on the current contribution margin ratio.
Compare scenarios using consistent annual revenue and cost classifications.
Assumptions & Important Notes
- All figures are annual and use the same currency.
- Variable cost behavior remains consistent as revenue changes.
- Fixed costs do not change within each example's revenue range.

Frequently Asked Questions
What does a 50% contribution margin ratio mean?
It means an estimated $0.50 of each $1 of revenue remains after variable costs to cover fixed costs and profit.
Why does a retail business often have a lower contribution margin ratio?
Product costs, fulfillment, and transaction costs may represent a larger share of each sale, though results vary by business.
Does break-even revenue guarantee a profit at that sales level?
No. It estimates the point where contribution margin equals the fixed costs entered, before items excluded from the calculation.
Can I use a loss-making example in the calculator?
Yes. A negative estimated operating income can help show the gap between contribution margin and fixed costs.
