Find how many units you need to sell to cover all costs.
Before launching a product or service, one of the most important numbers to know is your break-even point: exactly how many units you need to sell before you stop losing money and start turning a profit. This calculator takes your fixed costs, variable cost per unit, and selling price, and works out both the break-even unit count and the revenue needed to get there.
It also shows a quick table of estimated profit at different sales volumes relative to your break-even point, so you can see how profit scales once you're past that threshold.
What's the difference between fixed and variable costs?
Fixed costs stay the same regardless of how much you sell — rent and salaries are typical examples. Variable costs scale directly with each unit sold, like raw materials or packaging.
What is contribution margin?
It's your selling price minus your variable cost per unit — essentially how much each sale contributes toward covering your fixed costs before you start making profit.
What if my selling price is lower than my variable cost?
In that case you lose money on every unit sold, no matter how many you sell — there's no break-even point to reach. The calculator will flag this so you can adjust your pricing or costs.
