Educational estimate only. Not business, tax, or pricing advice. Assumes constant price, fixed costs, and variable cost per unit with no inventory or capacity limits.
Compare prices
Same fixed and variable costs| Price | Margin | Break-even units | Break-even revenue |

Key takeaways
- Sample only: $10,000 fixed · $50 price · $30 variable → about 500 units ($25,000.00 revenue); margin $20.00 per unit.
- Higher price or lower variable cost raises margin and usually lowers break-even units.
- Not a plan: Real businesses face capacity, taxes, and demand changes. This is transparent cost math for learning.
- How the break-even calculator works
How it works
Contribution margin is price minus variable cost per unit. Break-even units equal fixed costs divided by that margin. Details: how we calculate.

How does this break-even calculator work?
It uses contribution margin (price − variable cost) and break-even units = fixed costs ÷ margin. Sample: $10,000 fixed, $50 price, $30 variable → about 500 units and $25,000.00 revenue. Educational only.
What if price is less than variable cost?
Contribution margin is zero or negative, so the model reports that break-even is never reached under those constant assumptions.
