The formula
Break-even units = fixed costs ÷ contribution per unit, where contribution = price − variable cost. Add a target to cover it on top: (fixed + target) ÷ contribution. Fixed costs typically include rent, software and salaries; variable costs scale with each unit sold.
Frequently asked questions
How many units must I sell to break even?
Divide total fixed costs by the profit left on each unit after variable cost. With $1,000 fixed cost and $15 contribution, you need 67 units (~67).
What's contribution margin?
Price minus variable cost. It's the dollars each sale contributes toward covering fixed costs and, beyond break-even, profit.
