The formula
break-even units = fixed costs ÷ (price − variable cost) margin of safety = (expected − break-even) ÷ expected
Each unit contributes its margin towards fixed costs. Once those are covered, the rest is profit.
What to watch out for
A small price rise often moves break-even more than a similar cut in costs.
Frequently Asked Questions
How do I calculate break-even?
Fixed costs divided by contribution per unit. 20,000 ÷ (50 − 30) is 1,000 units.
