BREAK-EVEN CALCULATOR
Calculate break-even sales units, revenue and contribution per unit from your fixed costs, variable costs and selling price. Include a target profit.

A LITTLE CONTEXT GOES A LONG WAY
Fixed costs are costs that stay constant within the range you are planning, such as monthly rent or subscriptions. Variable cost per unit changes with each sale. Choose a unit that makes sense: a product, a billable hour or a standard service package. Keep all fixed costs and target profit in the same period.
Contribution per unit = selling price − variable cost. Break-even units = fixed costs ÷ contribution, rounded up to a whole unit. With fixed costs of 2,000, a price of 100 and variable cost of 60, each sale contributes 40 and 50 sales cover the fixed costs.
Units for a target profit = (fixed costs + target profit) ÷ contribution. This model assumes a constant selling price and unit cost. Discounts, changing costs, capacity limits or a mix of different products can change the outcome. The break-even revenue shown is whole-unit sales × price.

GOOD TO KNOW
Each additional unit would lose money before fixed costs. The tool asks you to change the inputs because selling more units will not reach break-even under those assumptions.
Yes. Treat a repeatable service or billable hour as the unit. Include the variable costs associated with delivering one unit and use a consistent period for your fixed costs.
