About this calculator
The break-even point is the sales volume at which total revenue equals total costs, so profit is zero. This calculator divides your fixed costs by the contribution margin (price minus variable cost per unit) to give the break-even quantity and the revenue it brings in — a core tool for pricing and business planning.
Frequently asked questions
What is the break-even formula?
Break-even units = fixed costs ÷ (price − variable cost per unit). The denominator is the contribution margin — the profit each unit adds toward covering fixed costs.
What if price is below variable cost?
Then every sale loses money and you can never break even at that price — the contribution margin is zero or negative. You must raise the price or cut the variable cost per unit first.
