Churn calculator
A free churn rate calculator: type in your MRR and monthly churn rate, see what it's costing you this month, this year, and — because churn compounds — what it actually does to your revenue over the next 12 months if nothing changes.

How the calculation works
As a churn rate calculator, the math above starts simple:
MRR × monthly churn rate. If you're
running $20,000 MRR and losing 4% of it a month, that's $800 gone every
month, or roughly $9,600 over a flat year.
But "flat year" is the wrong model, because churn compounds. You don't lose 4% of your starting MRR every month for 12 months — you lose 4% of whatever's left. Month one costs you $800. Month two, your base is $19,200, so 4% of that is $768. Total dollars lost across the year actually comes in under the flat estimate, because each month's 4% is taken from an already-shrunk base — but that's the misleading part, not the reassuring part. The number that matters is where you end up: by month twelve your MRR itself has fallen by more than a third, and it keeps compounding downward from there if nothing changes. The table above runs the actual month-by-month numbers for your inputs.
What counts as a "good" churn rate
This varies a lot by segment, but as a rough guide: self-serve SMB SaaS typically runs 3–5% monthly churn, with anything under 2% considered strong. Mid-market and enterprise products, with longer contracts and higher switching costs, should be well under 1% — some best-in-class teams hit 0.3–0.5%. If your number is meaningfully above your segment's range, the fix usually isn't a pricing change — it's understanding why people are leaving, which a churn number alone can't tell you.
The number this calculator can't give you
This tool answers "how much is churn costing me" — a real, useful number for a board slide or a prioritization argument. It can't answer the more important question: why those specific customers left. That answer usually isn't in your analytics dashboard either — a funnel chart shows you the drop-off, not the moment a user hit a broken flow, gave up on an unclear onboarding step, or rage-clicked a button that didn't work.
Session replay shows you that moment directly — the actual session, as video and as a transcript your agent can read. Watching the last few sessions before a handful of churned accounts cancelled is often faster than any amount of dashboard-staring, and it's the difference between "churn is 4%" and "churn is 4% because step 3 of onboarding silently fails on Safari."
