Enter your numbers, then calculate.
How it's calculated
Break-even units = Fixed costs ÷ (Price per unit − Variable cost per unit). The denominator is your contribution margin per unit — how much of each sale is left over after variable costs to pay down fixed costs.
Worked example
Fixed costs 10,000, price 50 per unit, variable cost 30 per unit: 10,000 ÷ (50 − 30) = 500 units, or 25,000 in revenue.
Frequently asked
What counts as a fixed cost versus a variable cost?
Fixed costs stay the same regardless of how many units you sell, like rent or salaries. Variable costs scale with each unit sold, like materials or per-unit shipping. Get this split right, or the break-even point will be wrong.
