Break-Even Calculator
Calculate break-even sales volume, revenue, and contribution margin with the WealthCalcLab break-even calculator.
Updated April 5, 2026
What this calculator does
This break-even calculator shows how many units or how much revenue you need before a product, service, or business line covers its fixed costs.
Break-even analysis is useful because it connects pricing, variable cost, and fixed overhead in one simple framework.
It is not a full business model, but it is one of the fastest ways to check whether a unit economics story is realistic.
How to use it
Enter total fixed costs, price per unit, and variable cost per unit.
Use break-even units when you manage operational volume. Use break-even revenue when you communicate targets to finance or sales.
Check the contribution margin carefully because it is the engine that covers fixed cost.
Formula
Break-even units = Fixed costs ÷ (Price per unit - Variable cost per unit)If price does not exceed variable cost, break-even is not possible because each unit fails to contribute toward fixed costs.
Methodology
Contribution margin per unit equals selling price minus variable cost per unit.
Break-even units equal fixed costs divided by contribution margin per unit.
Break-even revenue equals break-even units multiplied by price per unit.
Worked example
If a product sells for 60 and costs 25 in variable cost, each sale contributes 35 toward fixed costs.
With 5,000 in fixed cost, you need enough unit sales for those 35 contributions to fully cover that fixed amount.
How to interpret the results
Break-even is the minimum sustainable output level before profit starts to emerge.
A strong contribution margin ratio means each sale converts more revenue into fixed-cost coverage and profit potential.
Common mistakes
- Using average cost per unit instead of variable cost per unit.
- Ignoring price discounts or commissions that reduce true contribution margin.
- Treating break-even as a target margin of safety rather than the minimum line of viability.
Key terms
Quick definitions for the finance terms that matter on this page.
Fixed costs
Costs that do not change directly with each additional unit sold in the short term.
Contribution margin
The amount each unit contributes toward fixed costs and then profit after variable cost is covered.
Frequently asked questions
Clear answers on assumptions, interpretation, and the limits of each estimate.
What happens if price equals variable cost?
There is no contribution margin, so break-even cannot be reached.
Should salaries be treated as fixed costs?
Often yes for planning, unless they scale directly with unit volume in the short term.
Can break-even revenue replace a full forecast?
No. It is a threshold metric, not a substitute for a full demand or cash-flow forecast.
Why is break-even useful?
Because it quickly shows whether current pricing and cost structure can realistically support the business.
