About this tool
Break-even is fixed costs divided by contribution margin per unit. It answers the only question that matters before launch: how many do we need to sell before this stops losing money.
Contribution margin
Price minus variable cost. If it is negative, no volume will save you — every sale increases the loss.
Adding a profit target
Add the desired profit to fixed costs before dividing to get the volume needed to hit a specific goal.

Best practices
- Use consistent time periods and definitions — mixing monthly and annual inputs silently breaks every downstream number.
- Model a pessimistic and an optimistic case, not just the number you hope for.
- Use gross margin rather than revenue whenever a decision involves cash.
- Re-run the model quarterly with fresh inputs; stale assumptions age badly.
Why Break-Even Calculator matters
The difference between a healthy business and a leaking one is usually a couple of percentage points that nobody modelled.
Running the numbers before a pricing, hiring or spend decision turns an argument into an answer.
