About Break-Even Calculator
The Break-Even Calculator answers one of the first questions any business owner asks: how much do I need to sell before I start making money? Enter your total fixed costs — rent, salaries, software, insurance and anything else that stays the same regardless of volume — together with the price you charge per unit and the variable cost of producing or delivering each one.
The tool instantly works out the contribution margin (price minus variable cost), the contribution margin ratio, the number of units you must sell to cover every fixed cost, and the revenue those sales represent.
Understanding your break-even point turns a fuzzy gut feeling into a concrete target.
If the number of units looks unreachable for your market, you know the price is too low, the variable cost is too high, or the fixed-cost base is bloated — and you can model each lever by changing a single field.
The contribution margin tells you exactly how much profit every extra sale adds once you are past break-even.

FAQ
What is the contribution margin?
It is the price per unit minus the variable cost per unit — the amount each sale contributes toward covering your fixed costs and, after break-even, toward profit.
Why does it say I can never break even?
If your price is less than or equal to the variable cost per unit, every sale loses money on the variable side, so no volume can cover fixed costs. Raise the price or cut the variable cost.
Are units rounded?
Yes. Break-even units are rounded up to the next whole unit, because you cannot sell a fraction of a product to reach break-even.
