Break-Even Calculator
Enter your fixed costs, unit price, and variable cost per unit to find exactly how many units and how much revenue you need to break even.
Know your number before you commit
Break-even analysis answers a simple but decisive question: how much do I have to sell before this makes money? It's the first check on any new product, price change, or launch. Enter your fixed costs (rent, salaries, tooling), the price you charge per unit, and the variable cost to produce each one, and this calculator returns the exact unit count and revenue where you cross from loss into profit.
The key driver is the contribution margin — the slice of each sale left over after variable costs. A higher price or a lower variable cost lowers your break-even point sharply. If the price is at or below the variable cost, no volume will ever break even, and the calculator flags it.
How it's calculated
Contribution margin = price − variable cost. Break-even units = fixed costs ÷ contribution margin. Break-even revenue = break-even units × price. All computed live in your browser.
Frequently Asked Questions
What is the break-even point?
It is the number of units you must sell for total revenue to equal total costs — the point where you stop losing money and start making a profit. Below it you run a loss; above it, each sale adds profit.
How do I calculate break-even units?
Divide fixed costs by the contribution margin per unit (price minus variable cost per unit). If fixed costs are $10,000 and each unit contributes $25, you break even at 400 units.
What is contribution margin?
Contribution margin is the price of a unit minus its variable cost. It is the amount each sale contributes toward covering your fixed costs and, after break-even, toward profit.
Is this calculator free and private?
