What this calculator does

The Churn Reduction Impact calculator measures the financial effect of reducing customer churn: revenue retained, customer lifetime extended, and replacement acquisition spend avoided. You enter your customer base, revenue per customer, and current churn; the model shows what each point of improvement is worth.

It pairs naturally with the Customer Retention ROI calculator — churn reduction models stopping the leak; retention models the compounding value of the customers you keep.

How it works

Answer a short set of questions — volumes, time, and costs you already track. The calculator runs a pure, versioned formula and presents conservative, moderate, and optimistic scenarios, a receipt-style ledger tracing every figure back to an input, and a multi-year NPV/IRR view. Each report lists its assumptions so reviewers can challenge them line by line. See the methodology for how the models work, or view a complete sample report.

Benchmarks you can defend

Every constant used in-product is cited — the full source list, with caveats, is on the methodology page.

Frequently asked questions

Is the famous "5% retention → 95% profit" claim safe to put in a board deck?

Not as usually quoted. It mashes together three separate Bain/Reichheld publications from 1990–2001 covering different industries and eras. If you need a headline citation, the peer-reviewed Gupta et al. elasticity (1% retention improvement → 3–7% firm value) is far more defensible, and it is what this calculator cites.

Monthly or annual churn — which does the calculator want?

Enter the rate you actually track, in the period the calculator asks for. Be careful not to mix the two: monthly benchmark figures (e.g. B2B SaaS ~3.5%) are an order of magnitude smaller than annual industry figures, and mixing them is the most common churn-model error we see.

Is the Churn Reduction Impact calculator free?

Your first calculator is free forever, with unlimited re-runs and one saved report — no card required. You enter your email to view and save results, and upgrading to Pro unlocks all 13 calculators, unlimited reports, exports, and share links.

Can I change the assumptions?

Yes — every assumption is editable before you calculate, and the report records exactly what you used. Industry constants are cited on the methodology page, and the receipt-style ledger traces each figure in the result back to an input.
