Frequently asked questions

What is the break-even formula?

Break-even units = fixed costs / (price per unit − variable cost per unit). The denominator is the contribution margin each unit adds toward covering fixed costs.

What is contribution margin?

Contribution margin is the selling price minus the variable cost per unit. It is the amount each sale contributes to covering fixed costs and then profit.

What if price is below variable cost?

Then every sale loses money and there is no break-even point. You must raise the price or cut variable cost until the contribution margin is positive.
