## How it works

Current and new revenue equal price × units. Contribution equals (price − variable cost) × units. Maximum demand loss preserving current contribution equals 1 − current unit contribution ÷ new unit contribution.

## Worked example

Moving from $50 to $60 with $30 variable cost and a 10% volume decline increases contribution from $20,000 to $27,000 on 1,000 current units.

## Assumptions

- Variable cost per unit remains constant.
- The entered volume change represents the complete demand response.
- Discounts, mix, churn, taxes, competitor reactions, and capacity changes are excluded.

## Common questions

### What does allowable demand loss mean?

It is the volume decline that leaves modeled contribution unchanged, not a predicted customer response.

### Why compare contribution?

Revenue alone ignores variable costs and can make a price change look better or worse than its unit economics.

### Is demand response linear?

Not necessarily; this calculator uses only the single volume-change assumption you enter.
