How it works

  • Monthly churned revenue = MRR x churn %.
  • Annual churned revenue = monthly churned revenue x 12 (simple).
  • For a compounding view, retained revenue is approximately MRR x (1 - churn%)^12.

Modeling tips

  • Use revenue churn, not logo churn, for financial impact.
  • Enter a monthly churn rate, not an annualized percentage.
  • Use a recent cohort or trailing average to avoid seasonality bias.
  • If you track net churn, use it to reflect expansion offsets.
  • Run a low and high churn scenario to understand sensitivity.
  • If churn is segmented by plan, model each plan separately and sum.

Validation checks

  • Monthly churned revenue should equal MRR x churn rate.
  • Annual churned revenue should equal monthly churned revenue x 12.
  • If churn exceeds 20%, confirm you are using the correct period.
  • If churn rate is above 100%, inputs are invalid.

Common mistakes

  • Using logo churn instead of revenue churn for financial impact.
  • Entering annual churn as a monthly percentage.
  • Ignoring cohort differences when churn varies by segment.
  • Assuming this model accounts for expansion or new sales.

Interpretation

  • Use monthly churned revenue to size the immediate leakage problem.
  • Treat the annual churned revenue as a directional estimate, not a forecast.
  • If churn is high, prioritize retention work before pricing changes.
  • Segment churn results by plan to find the biggest leaks.

Use cases

Retention prioritization
Quantify the revenue at risk to justify retention initiatives.
Pricing risk check
Estimate revenue impact if churn rises after a price increase.

Mini walkthroughs

Churn leakage estimate
  1. Enter current MRR and monthly churn rate.
  2. Review monthly churned revenue.
  3. Use annual estimate as directional risk.
Stress test churn
  1. Increase churn by 1-2 percentage points.
  2. Compare annual churned revenue outputs.
  3. Decide if retention work is urgent.

Scenarios

Low churn SaaS
2% monthly churn on 50k MRR to quantify manageable losses.
High churn SaaS
5% monthly churn to highlight annual revenue leakage risk.
Churn sensitivity
Compare 2% vs 4% churn to show how small changes drive large impact.
Pricing change stress test
Increase churn by 1-2 points to estimate downside risk from a price increase.

Edge cases

  • If churn rate is 0, churned revenue will be 0; verify this is realistic.
  • If churn exceeds 100%, input is invalid and should be corrected.
  • If MRR is 0, churned revenue will be 0; confirm you have active revenue.
  • Very high churn rates can make linear annual estimates misleading; consider compounding.

FAQ

Is this logo churn or revenue churn?
This calculator uses revenue churn. Logo churn can be very different depending on customer mix.
Is annual churn just monthly churn x 12?
This tool shows a simple annualized estimate. For higher churn rates, compounding effects can make the true annual impact larger.
What churn rate should I enter?
Use a recent cohort-based revenue churn rate (gross or net). If you only have logo churn, treat this as a directional estimate.
What is the difference between gross and net churn?
Gross churn looks only at lost revenue. Net churn includes expansion and contraction, which can offset churn.
How do I reflect cohort improvements?
Run separate scenarios for older cohorts vs new cohorts to see how churn improvements affect the annual loss.
