How it works
Each unit you sell contributes its price minus its variable cost. Divide your fixed monthly costs by that contribution margin and you get the number of units needed to break even.
Formula
Contribution margin = Price − Variable costBreak-even units = Fixed costs ÷ Contribution marginBreak-even revenue = Break-even units × Price
Frequently asked questions
Do investors care about break-even at seed stage?
They care less about the date and more about unit economics. A healthy contribution margin shows that growth will eventually pay for itself.
What if my variable cost is higher than my price?
Then every sale loses money and you can never break even by selling more. Fix pricing or cost per unit first.
What counts as a fixed cost?
Costs that do not change with volume in the short term: salaries, rent, software subscriptions. Payment fees, hosting per customer and shipping are usually variable.
