Common questions about the free online break even calculator.

Divide your fixed costs by the contribution margin, which is the selling price per unit minus the variable cost per unit.

Fixed costs do not change with output, such as rent, insurance and salaries. They are paid whether you sell anything or not.

It is what each sale leaves after variable costs, and that amount goes towards covering fixed costs before any profit is made.

It is the money you must take in to cover all of your costs. The tool multiplies the break even units by the selling price.

Then every sale loses money and no sales volume can break even. The tool reports this instead of showing a negative number of units.

You cannot sell part of a unit, so the practical break even quantity is the next whole unit above the calculated figure.

No. At the break even point total revenue equals total costs, so profit is exactly zero and every extra sale adds profit.

Yes. Treat the average fee as the price and the direct cost of delivering the service, such as materials, as the variable cost.
