Frequently asked questions

How do you calculate break-even?+

Break-even units = fixed costs ÷ (price − variable cost per unit). The bit in brackets is the contribution margin — what each sale adds toward covering your fixed costs.

What is the contribution margin?+

The price of one unit minus its variable cost. It's how much each sale contributes to fixed costs and, after break-even, to profit.

Why is there no break-even?+

If the price is at or below the variable cost per unit, every sale loses money, so you never break even. Raise the price or cut the variable cost.
