What this means

You need to sell about 500 units to cover your fixed costs. Each unit contributes $20.00 toward those costs. Every sale beyond the break-even point is profit.

About the Break-Even Calculator

The ByteTools Break-Even Calculator tells you how many units you must sell to cover your costs. Enter your total fixed costs, the selling price per unit and the variable cost per unit, and it returns the break-even quantity, the revenue at that point and the contribution margin per unit.

It is a core tool for startups, small businesses and product managers testing a price or a new product idea. Selling above the break-even quantity produces profit; below it, you make a loss.

The tool guards against an impossible setup where price is not above variable cost. Everything is computed in your browser with nothing uploaded, and the results are planning estimates, not financial advice.

Frequently asked questions

How do you calculate the break-even point?

Divide total fixed costs by the contribution margin per unit, which is the selling price minus the variable cost per unit. The result is the number of units you must sell to cover all costs. Multiply by the price to get break-even revenue.

What is contribution margin?

Contribution margin is the selling price of a unit minus its variable cost. It is the amount each sale contributes toward covering fixed costs, and after break-even, toward profit. A higher contribution margin means you reach break-even with fewer sales.

What if the price is lower than the variable cost?

Then every sale loses money and there is no break-even point, no matter how many units you sell. The calculator detects this and shows a warning, prompting you to raise the price or cut the variable cost.

Why are break-even units rounded up?

You cannot sell a fraction of a unit and still fully cover costs, so the tool rounds up to the next whole unit. Selling that many units or more ensures your total revenue meets or exceeds total costs.

Is my business data private?

Yes. The calculation runs entirely in your browser and nothing is uploaded or saved, so your cost and pricing figures stay confidential.
