Method & formula

Starting customers are multiplied by monthly churn rate. Churned customers are multiplied by ARPU to estimate MRR lost, then annualised by multiplying the monthly run-rate impact by twelve.

  • Churned customers = starting customers x monthly churn rate
  • Monthly MRR lost = churned customers x ARPU
Example

1,000 customers at 3% monthly churn and 50 ARPU implies 30 churned customers and 1,500 MRR lost for that month.

FAQ

Does the annualised figure compound churn?

No. It annualises the current monthly run-rate loss by twelve. It is not a cohort or compounding forecast.

Is this a forecast?

No. It is deterministic planning arithmetic based on the assumptions you enter. Actual commercial performance can differ.
