Profitability & pricing

Price increase impact calculator

Most owners overestimate how much volume a price rise costs them. This tool gives the hard number: the percentage of customers you could lose and still finish ahead.

  • Expected churn sits below break-even loss, so the increase should improve profit.

How to use this calculator

  1. 1Enter current price, variable cost per unit and current volume.
  2. 2Enter the price increase you are considering.
  3. 3Compare break-even volume loss with the churn you realistically expect.

The break-even volume rule

Break-even volume loss = price increase / (contribution margin ratio + price increase). At a 40% contribution margin, a 10% price rise can survive a 20% loss of unit volume before profit falls.

The lower your margin, the more powerful a price rise is: a 5% increase on a 20% margin business lifts contribution by a quarter.

Applying the increase without churning customers

Segment first. Raise prices on new customers and low-negotiating-power segments before touching your largest accounts, and give notice with a reason tied to input costs or service scope.

Track units, not just revenue, for two periods afterwards. If unit loss lands well under the break-even figure here, the increase was overdue.

Frequently asked questions

Should I raise prices across the board?

Rarely. Cohort or segment increases usually deliver most of the profit with a fraction of the churn risk.

What if my costs rose more than my price?

Enter the higher variable cost together with the proposed price. The tool shows whether the increase restores your original contribution per unit.

How does a price rise affect business value?

Sustainable price increases flow straight to EBITDA, so at a 4x multiple every extra unit of annual profit adds roughly four to enterprise value.
