How do you calculate a break-even point?

Divide fixed costs by the contribution margin (price per unit minus variable cost per unit). The result is the number of units you need to sell before revenue covers every fixed and variable cost. Sell fewer units and you are operating at a loss; sell more and each additional unit is pure profit at the contribution margin rate.
