What is the Break-Even Calculator?
Before a launch or a new product, you should know how many sales it takes to cover your costs. Everything after the break-even point is profit.
Enter your fixed costs, price and variable cost per sale to get your break-even units and revenue, and your contribution margin.
How to use the Break-Even Calculator
- Enter fixed costs for the month or the launch — tools, hosting, design, committed ad budget.
- Enter the price per unit.
- Enter the variable cost per unit — payment fees, fulfilment, affiliate commission.
Understanding your results
- Break-even sales
- Fixed costs ÷ (price − variable cost), rounded up.
- Contribution margin
- What each sale contributes towards fixed costs and profit.

Yes — they are paid per sale.
