What this planner helps you decide

Best for

Owners stress-testing a proposed increase against explicit volume-loss assumptions.

Outputs

Tolerable volume loss, elasticity scenario profit and ordered sensitivity results.

Start here

Enter the current and proposed ex-tax prices, then test a bounded demand-response assumption.

Use a different tool when: Do not use this to design volume tiers; use Tiered Pricing Profit Planner for that decision. Use this tool to test a price increase.

Read the full methodology

Data used here

  • The estimate uses your inputs and the general business formula documented in the methodology.

Decision checks

Act on the result

Set a maximum acceptable volume-loss boundary before approving the increase.

Stress-test the decision

Retest demand response across a bounded range rather than relying on one elasticity assumption.

When this estimate can be misleading

  • Results depend on the accuracy and consistent basis of your inputs.
  • The planner does not predict demand, competitor behaviour or supplier terms.
  • Use the result as educational business decision support, not accounting, tax or legal advice.
  • The scenario result compares the proposed price gain with the explicit demand response entered by the user.

Educational estimate, not advice. See all assumptions & limitations โ†’

Frequently asked questions

How do I test a price increase?

Set a maximum acceptable volume-loss boundary before approving the increase.

Which planning assumptions should I stress-test?

Compare a plausible alternative scenario and verify the decision-critical assumption that changes the plan most.
