Break-Even Sales & Revenue Calculator

Calculate unit sales and gross revenue needed to cover fixed and variable business costs.

Break-even volume is fixed costs divided by unit contribution margin—the selling price remaining after variable unit cost.

  • Key formula: Contribution = price − variable cost. Break-even units = fixed costs ÷ contribution. Target units add the desired profit to fixed costs first.

Inputs and scenario calculations remain local. Results depend on stable price and cost assumptions.

Good questions. Clear answers.

What is the break-even point?

It is the sales volume where total revenue equals total fixed and variable costs, producing neither operating profit nor loss under the model's assumptions.

What is contribution margin?

Unit contribution margin is selling price minus variable cost per unit. It is the amount each unit contributes toward fixed costs and then profit.

Why should break-even units be rounded up?

Businesses normally cannot sell a fraction of a unit, and rounding down would leave part of fixed costs uncovered. The headline unit result therefore rounds up.
