Churn recovery calculator
Most CRMs log a churn reason about as well as they log a lost reason. One line, often generic, sometimes blank. This shows how much revenue left with no real explanation, and what a conservative recovery could be worth.
Under two minutes. No email. Nothing you enter leaves your browser.
Your result
Unexplained churned revenue
Revenue lost in the last 12 months where the reason field tells you nothing.
Total value lost to churn
Churned accounts with no real reason
Your gross retention rate
All figures are in the currency you entered.
What a conservative recovery could be worth
Not every churned account comes back. Set your own view of how much of that unexplained value was genuinely winnable. The default range of 5 to 15 per cent is deliberately cautious, reflecting how little reliable public data exists on B2B win-back rates.
Move the percentages to whatever you believe. This is an estimate you control, not a forecast and not a promise of recovered revenue.
Your retention against the benchmark
You've found real unexplained churned revenue.
The diagnostic finds out what's driving it, and builds the plan to fix it.

The formula
- Unexplained churned accounts. Customers lost or not renewed, multiplied by the share with no real reason logged. We round to the nearest whole account.
- Unexplained churned value. Unexplained churned accounts, multiplied by your average annual account value. This is the headline figure.
- Recoverable range. Unexplained churned value, multiplied by the low and high percentages you set. The defaults of 5 and 15 per cent are deliberately cautious, and the range is an editable estimate, not a projection.
- Gross retention rate does not change any calculation. It is context only, used for the benchmark comparison.
A check you can do on paper
40 churned accounts at an average value of 25,000, with 70 per cent unexplained, gives 28 unexplained accounts, 700,000 of unexplained churned value, and a default recoverable range of 35,000 to 105,000.
Benchmark sources
- Gross retention rate for B2B SaaS, roughly 88 to 95 per cent, with the top quartile above 95 per cent. SaaS Capital and Benchmarkit, 2025 benchmarking data.
- Overall B2B retention, roughly 72.5 per cent, with wide variation by sector. CustomerGauge.
- Win-back and reactivation rates are not used as a benchmark here. Most published figures come from e-commerce and email marketing, not B2B account recovery, so the recoverable range above is left unbenchmarked and fully editable instead.
