What this calculator does
This break-even calculator is built for the moment you need a defensible number — quoting a client, comparing options, or checking someone else's math — not a generic estimate.
Break-even analysis tells you the sales volume needed to cover all fixed and variable costs.
How to use the Break-even Calculator
- Start by entering **Fixed Costs** — this anchors every downstream number in the break-even calculator.
- Fill in **Price per Unit** to reflect your specific situation.
- Set **Variable Cost per Unit**; the result and chart recalculate the moment you finish typing.
- Review the breakdown card for the components that make up the headline number.
- Use Copy, Share, or Print to save the exact scenario — or star it to keep it in your favorites.
The formula
Break-even units = Fixed Costs / (Price − Variable Cost)
Worked example
$20k fixed, $50 price, $20 variable = 667 units.
Common mistakes
- Ignoring mixed cost structures
- Not stress-testing volume assumptions
- Missing indirect costs
When to use it
Use for pricing decisions, product launches, and profitability analysis.
