How many sales until you're in profit?
Enter your fixed costs, price, cost per unit and fees to see how many units cover your costs, the units for the profit you want, and a chart of profit against sales.

The starting numbers are only an example. Fixed costs are what you pay whatever you sell, such as software, rent, salaries and a product launch budget. Use the same period, such as a month, for every number. Currency changes the symbol only.

How it’s calculated
Fees per unit = price × fee %Contribution margin = price − variable cost − fees per unit. It’s what each sale puts toward fixed costs and then profit.Contribution margin ratio = contribution margin ÷ priceBreak-even units = fixed costs ÷ contribution margin, rounded up to a whole unit.Break-even revenue = fixed costs ÷ contribution margin ratioUnits for a profit target = (fixed costs + target) ÷ contribution margin, rounded up.Profit = units × contribution margin − fixed costs, which is the line on the chart.Margin of safety = (expected units − break-even units) ÷ expected units: how far sales can fall before you lose money.
Example: 3,000 fixed, a 40 price, 15 variable cost and 10% fees give 4 in fees and a contribution margin of 21. 3,000 ÷ 21 = 142.86, so you break even at 143 units.
