Finance Tool

Know the exact unit volume you need to stop losing money.

Plug in your fixed costs, variable cost per unit, and selling price. The calculator shows your break-even point, contribution margin, target-profit volume, and a simple visual mix of where each sales dollar goes.

Inputs

Use your real monthly or per-project numbers. All values update live.

Fixed costs Rent, salaries, software

Variable cost per unit Materials or delivery

Selling price per unit Revenue from one sale

Target profit Optional stretch goal

Formula: break-even units = fixed costs ÷ (selling price - variable cost per unit)

Break-even units 0 Sell 0 units to cover all fixed costs.

Break-even revenue $0 This is the top-line revenue needed to hit zero profit.

Contribution margin $0 Each unit contributes $0 toward fixed costs and profit.

Target-profit units 0 Units needed to cover fixed costs and profit goal.

Contribution margin ratio

This shows how much of each sales dollar is left after variable costs.

0.0% contribution margin ratio The remaining share of every sales dollar can absorb fixed costs, then become profit.

Per-unit breakdown

A quick visual split between variable cost and profit contribution for one unit at your current price.

Variable cost share $0

Fixed-cost recovery and profit share $0

What to watch If your contribution margin gets too thin, small pricing or cost shifts will dramatically increase your break-even volume.
