How this calculator works

The Break-Even Calculator helps founders, freelancers, and operators estimate how many units they must sell before a product or service stops losing money. Enter fixed cost, price per unit, and variable cost to estimate contribution margin, break-even units, and break-even revenue. The calculator updates instantly and adds a comparison table plus chart so you can test the sensitivity of the result before you use it in a decision.

Inputs

Recurring or upfront fixed cost that must be covered first.
Average selling price collected for one unit sold.
Direct variable cost required to produce or deliver one unit.

Outputs

Amount left from each unit sale to cover fixed costs and profit.
Number of units needed to cover the full fixed-cost base.
Total revenue needed to reach break-even.

Assumptions

Unit price and variable cost stay constant across the scenario.
The model ignores taxes, financing, and step changes in overhead.

Tips

If your margin is thin, test several prices and variable costs.
Break-even is not a profit target; it only covers fixed costs.

Formula guide

Use these formulas to audit the output or explain it to someone else.

2 formulas

Contribution Margin = Price per Unit - Variable Cost per Unit

Break-Even Units = Fixed Cost ÷ Contribution Margin

Usage examples

Review a ready-made scenario, copy it, then tweak inputs to match your case.

Product launch check

Inputs

Example input Fixed cost: $40,000.00
Example input Price per unit: $60.00
Example input Variable cost: $22.00

Outputs

Example result Contribution margin: $38.00
Example result Break-even units: 1,052.63
Example result Break-even revenue: $63,157.89

Contribution margin is the key lever; if it drops, the required sales volume rises very quickly.

Break-even units by price

Price per unit	Contribution margin	Break-even units
$35.00	$17.00	1,470.59
$40.00	$22.00	1,136.36
$45.00	$27.00	925.93
$50.00	$32.00	781.25
$55.00	$37.00	675.68

Small price changes can move break-even fast when variable cost stays fixed, so test realistic price points.
