GoodContribution margin supports break-even
Each unit contributes $60.00 toward fixed costs and profit.
Price sensitivity
Compare how the result changes when a key assumption moves.
| Scenario | Price per unit | Contribution margin | Break-even units |
|---|---|---|---|
| Price -10% | $72.00 | $52.00 | 231 |
| Base price | $80.00 | $60.00 | 200 |
| Price +10% | $88.00 | $68.00 | 177 |
Operator context
Use this when
- Use before pricing a product, approving a campaign, opening a location, or committing fixed costs.
- Use to translate cost structure into minimum viable volume.
- Use before sensitivity testing price, variable cost, or demand.
Interpretation rules
Non-viable marginCritical
If variable cost is greater than or equal to price, volume cannot fix the model.
Build a bufferNeutral
Break-even is the floor; operators should plan demand above it for margin of safety.
Operator notes
- Separate fixed and variable costs before trusting the result.
- Compare required volume with actual demand and operational capacity.
Watch for
- Misclassifying fixed and variable costs can make the model falsely optimistic.
- Single-product break-even can mislead when sales mix varies.
