Break-even Point Calculator
Find break-even revenue, quantity and contribution margin from fixed cost, unit price and variable cost.
Enter fixed cost, unit price and variable cost to find the break-even point.
The break-even point (BEP) is where profit is zero. Contribution margin = (price − variable cost) ÷ price; break-even revenue = fixed cost ÷ contribution margin. Quantities are rounded up to the minimum whole units. Use the same period (e.g. monthly) for fixed and variable costs.

What break-even is
The break-even point is where revenue equals total cost — no profit, no loss. Sell more and you profit; sell less and you lose. It is the first figure to check before starting a business.
Using contribution margin
Contribution = price − variable cost; contribution margin = contribution ÷ price. Break-even revenue = fixed cost ÷ contribution margin; break-even quantity = fixed cost ÷ contribution. Use the same period for fixed and variable costs.
Reaching a target profit
To earn a target profit, divide (fixed cost + target profit) by the contribution. Enter a target profit and the tool returns the required quantity.

Frequently asked questions
How is the break-even point calculated?
Break-even revenue = fixed cost ÷ contribution margin; break-even quantity = fixed cost ÷ (price − variable cost).
What is contribution margin?
The share of each sale left after variable cost that goes toward fixed cost. A higher margin means a lower break-even point.
How much must I sell for a target profit?
(Fixed cost + target profit) ÷ contribution. Enter a target profit to get the required quantity.
Are the inputs sent anywhere?
No. Everything is calculated in your browser and nothing is uploaded.
