Break-Even
Worldwide — arithmetic, no local rules
Classic cost-volume-profit analysis: contribution margin, break-even units and revenue, margin of safety if you supply current volume, and the leverage a price change has on all of it.
The numbers
- Break-even units / month
- 741
- Break-even revenue / month
- 33,333
- Contribution margin
- 27.00 (60%)
- per unit, after variable costs
The operator’s read
Worth knowing
Price leverage: a 10% price increase cuts break-even from 741 to 635 units (−14%). Small price moves shift break-even far more than equal cost cuts.
Methodology
Contribution margin = price − variable cost per unit. Break-even units = fixed costs ÷ contribution margin; break-even revenue = break-even units × price.
Margin of safety = (current units − break-even units) ÷ current units — the demand cushion before losses begin.
Assumes linear costs and a single price point. Mixed products need a weighted-average contribution margin; step-fixed costs (e.g. a second shift) break the linearity at scale.
