Break-Even Calculator

1. 01Enter your fixed costsType the costs that do not change with volume, such as rent, salaries, or software.
2. 02Enter price and variable cost per unitType the selling price of one unit and what each unit costs to make or deliver.
3. 03Read the break-even pointThe break-even units, revenue, and contribution margin update as you type.

• Test a priceSee how many sales a price needs to cover your costs.
• Plan a product launchCheck whether the expected volume can reach break-even.
• Weigh a cost changeSee how a lower variable cost or higher fixed cost moves the break-even point.

• A simple caseFixed costs of 1,000, a price of 10, and a variable cost of 4 give a contribution of 6 per unit and a break-even of about 167 units, or 1,667 in revenue.
• Higher priceRaising the price lifts the contribution margin, so fewer units are needed to break even.
• No break-evenIf the price is not above the variable cost, each sale loses money and there is no break-even point.

Each unit contributes its price minus its variable cost toward fixed costs; that is the contribution margin. Break-even units = fixed costs / contribution margin, and break-even revenue = break-even units x price. The price must exceed the variable cost for a break-even point to exist.

You enter fixed costs, price per unit, and variable cost per unit in the same currency. The tool returns the break-even units, the break-even revenue, and the contribution margin per unit. It assumes a single product with a constant price and variable cost.

Change any input to test scenarios: a higher price, a lower variable cost, or added fixed costs. Fractional units are shown, so round up to the next whole unit in practice.

A common mistake is putting a per-unit cost in the fixed costs box, or a total cost in the per-unit box. This is a single-product model; it does not handle a product mix, volume discounts, or stepped fixed costs. This is an educational estimate to help you plan and price, not financial, accounting, or tax advice. Check the figures against your own records or a qualified professional before a real decision.

What is the contribution margin?

It is the selling price minus the variable cost per unit, the amount each sale contributes toward fixed costs and then profit.

Why is there no result sometimes?

If the price is not higher than the variable cost, each unit loses money, so there is no break-even point.

Should I round the units up?

Yes. You cannot sell a fraction of a unit, so round the break-even units up to the next whole number.

Does it handle several products?

No. It models a single product. For a mix, estimate a blended price and variable cost.

Is my data saved?

No. Everything runs in your browser and nothing you enter is stored.
