Break-Even Calculator
The number every business owner needs: how many units — and how much revenue — it takes just to cover your costs before you make a dime of profit.
The break-even formula
Break-even units = Fixed costs ÷ Contribution margin
For a target profit: (Fixed costs + Target) ÷ Contribution margin
Fixed $10,000, price $50, variable $30:
Contribution margin = $20/unit → break-even = 10,000 ÷ 20 = 500 units = $25,000 in revenue.
Want $6,000 profit? (10,000 + 6,000) ÷ 20 = 800 units.
Using break-even to make decisions
Break-even turns pricing and cost questions into concrete unit targets. A price increase from $50 to $55 lifts the contribution margin to $25 and drops break-even to 400 units — a 20% reduction from a 10% price bump, because fixed costs spread over a bigger margin. That leverage is why cutting variable cost or nudging price often beats chasing volume. Pair this with the margin calculator for pricing and the markup calculator for cost-plus targets; for a solo operation, factor self-employment tax into the profit you actually keep.
Frequently asked questions
How do I calculate the break-even point?
Fixed costs ÷ (price − variable cost). $10,000 ÷ ($50 − $30) = 500 units.
What is contribution margin?
Price minus variable cost per unit — what each sale contributes to fixed costs, then profit.
How do I reach break-even faster?
Raise price, cut variable cost, or lower fixed costs — each shrinks the units needed.
