Break Even Calculator

Estimate break-even units, break-even revenue, contribution margin, total profit, and margin of safety based on selling price, variable cost, fixed costs, and expected sales volume.

Calculate Break Even

Break-even units = (fixed costs + additional costs − additional revenue) ÷ (selling price − variable cost). Break-even revenue = break-even units × selling price.

How the break even calculator works

Contribution margin per unit:
The calculator subtracts variable cost per unit from selling price per unit.

Break-even units:
Fixed costs are divided by unit contribution margin to estimate the number of units needed to break even.

Break-even revenue:
The break-even unit result is converted into a revenue target using the selling price.

Projected profit:
The expected unit sales entered are used to estimate whether your current plan is below, at, or above break even.

Why break-even estimates matter

Break-even estimates help businesses understand minimum sales targets, compare pricing choices, and evaluate whether a product or service is likely to become profitable.

This tool is especially useful for launch planning, pricing strategy, and small business forecasting.

What your result means

Your result shows break-even units, break-even revenue, contribution margin, expected revenue, expected profit, and margin of safety based on the values entered.

Break-even calculator tips

Frequently asked questions

What is break even?

Break even is the point where total revenue equals total cost, so profit is zero.

What is contribution margin?

Contribution margin is the amount left from each unit sold after variable cost is subtracted. It helps cover fixed costs and profit.

What is margin of safety?

Margin of safety shows how much your expected sales exceed the break-even point.

Why can break even be impossible?

If selling price is less than or equal to variable cost per unit, each sale does not contribute enough to cover fixed costs.
