Engineering Assumptions
- Selling price and variable cost per unit are constant across the analysis range.
- Fixed costs do not change with volume within the same range.
- All percentages and inputs are user-defined; the calculation is purely arithmetic and assumes no particular code or specification.
Formula Summary
- Contribution per unit = selling price − variable cost
- Break-even units = fixed costs ÷ contribution
- Break-even revenue = break-even units × selling price

Engineering Insight
Contribution is the real driver of break-even: a small drop in selling price sharply raises the required volume because the denominator shrinks. Passing break-even is where profit begins, not where it ends.
Recommended Action
Test price-reduction and variable-cost-increase scenarios before committing to a production volume or a long-term contract.
