Estimated leak over 12 months
$28,992
30.2% of a full year of revenue — $79 a day, at the current rate.
- Customers who leave
- $24,960
- Declines never recovered
- $4,032
An estimate of exposure at the current rate, not a forecast: it assumes a flat baseline (no new customers, no expansion) and that everything else stays constant. Churned revenue is counted for every month it stays missing, which is why it grows faster than the failed-payment line.

About Leakmeter
Two leaks drain a subscription business, and founders fix them in different places. Involuntary churn is a card that declines and is never retried — that revenue was already won, it just never arrives. Voluntary churn is a customer who leaves, and it compounds: someone lost in January is missing for the other eleven months too.
Leakmeter estimates both against a flat baseline — no new customers, no expansion — because that answers the only question worth asking: at the current rate, and assuming other factors stay constant, what does this cost over the next twelve months? It is an estimate of exposure, not a forecast of guaranteed loss.
Questions
- Why is the churn number so much larger than the failed-payment number?
- Because churned revenue keeps costing you. A customer lost in month one is missing for twelve months, month two for eleven, and so on. Declines are counted once each, in the month they happen.
- What counts as a good monthly churn rate?
- There is no single number: acceptable churn varies heavily by SaaS model, price point and customer segment. Lower is generally better, and a rate that keeps a flat baseline shrinking faster than you can replace it is the one worth acting on.
- Do you store what I type?
- No. The whole calculation runs in your browser. There is no request, no account and no email field.
