What does this calculator estimate?
Price increase calculator: model how a price rise affects demand, volume, and contribution profit so you can see the real impact before you raise. Free, private.
How this calculator works
Formula
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 to verify
- 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.
Frequently asked 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.
