Enter your fixed costs, selling price per unit and variable cost per unit. The calculator shows the break-even quantity and the revenue needed to reach it.
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.
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.
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.
