What this break-even calculator shows you
A break-even calculator finds the sales level where your total revenue equals your total costs — the point where you stop losing money and start making a profit. Enter your fixed costs, price per unit and variable cost per unit, and it returns your break-even units, break-even revenue and contribution margin.
How to calculate the break-even point
Break-even units = Fixed costs ÷ (Price − Variable cost)
The bottom part — price minus variable cost — is your contribution margin, the profit each unit contributes toward fixed costs. With $10,000 in fixed costs, a $50 price and $30 variable cost, your margin is $20, so you break even at 500 units (or $25,000 in revenue).

Break-Even Calculator FAQ
How do I calculate the break-even point?
Divide your fixed costs by your contribution margin (price minus variable cost per unit). With $10,000 fixed costs, a $50 price and $30 variable cost, that's $10,000 ÷ $20 = 500 units.
What is contribution margin?
Contribution margin is the price of a unit minus its variable cost — the amount each sale contributes toward covering fixed costs and then profit. A $50 product with $30 variable cost has a $20 margin.
What's the difference between fixed and variable costs?
Fixed costs stay the same regardless of sales, like rent and salaries. Variable costs rise with each unit sold, like materials, shipping and transaction fees.
How can I lower my break-even point?
Raise your price, reduce variable cost per unit, or cut fixed costs. Each increases your contribution margin or shrinks what you need to cover, so you break even on fewer sales.
What does break-even revenue mean?
It's the total sales dollars at the break-even point — your break-even units multiplied by your price. Above it you make a profit; below it you make a loss.
