Formula
Break-Even Revenue = Fixed Costs / (Contribution Margin % / 100)
Break-even revenue estimates how much revenue is required to cover fixed costs once contribution margin is taken into account. It is a practical planning metric because it turns cost structure into a concrete sales threshold rather than a vague profitability target.
How to use this calculator
- 1Enter total fixed costs for the period or scenario.
- 2Enter contribution margin as a percentage, not as a decimal.
- 3The calculator divides fixed costs by contribution margin in decimal form to estimate break-even revenue.
What this metric tells you
A higher break-even revenue means the business needs more top-line sales before it begins to cover fixed costs.
If contribution margin improves, break-even revenue falls because each revenue dollar contributes more toward fixed costs.
This metric is especially useful when paired with pricing, margin, and ROAS planning to understand how structural economics affect growth targets.
Common use cases
- Estimating how much revenue is needed before a campaign, product line, or business breaks even.
- Comparing how fixed-cost changes alter required revenue thresholds.
- Testing whether improved contribution margin materially lowers the revenue needed to stay viable.

Worked example
Example: calculating break-even revenue from fixed costs and contribution margin
If fixed costs are $15,000 and contribution margin is 40%, break-even revenue is $37,500. That means the business needs about thirty-seven thousand five hundred dollars in revenue before fixed costs are fully covered under this margin structure.
FAQ
What does break-even revenue tell you?+
It tells you the revenue threshold needed to cover fixed costs based on the contribution margin you are working with.
Why use contribution margin instead of gross margin?+
Contribution margin is often the stronger planning input because it reflects the portion of revenue available to cover fixed costs after variable costs are removed.
Can break-even revenue fall without fixed costs changing?+
Yes. If contribution margin improves through pricing, lower variable costs, or product mix, the revenue needed to break even will fall.
Is this the same as a sales forecast?+
No. It is a threshold calculation, not a forecast. It shows the revenue level needed to cover fixed costs under the assumptions you entered.
