FAQ
What churn rate should I compare against?

Start with your own cohorts by product, plan, acquisition channel, tenure and customer type. External benchmarks are only useful when their period, churn definition and business model match yours.

What is Net Revenue Retention (NRR)?

NRR measures recurring revenue retained from the starting customer cohort after churn and downgrades, plus expansion. It excludes revenue from new customers. A value above 100% means expansion exceeded churn and contraction for that cohort.

How do I reduce churn for African subscribers?

Tag voluntary cancellation, payment failure, downgrade and inactivity separately. Review retention by cohort, test onboarding and value delivery, make supported payment recovery easier, and measure whether each intervention changes retention.

Measurement Checks

Keep the denominator stable

Customer churn uses customers at the start of the period. New customers do not enter that denominator. Reconcile ending customers before accepting a Method A result.

Keep new revenue out of NRR

Use only the starting cohort's churn, contraction and expansion. Revenue from newly acquired customers belongs in total growth, not NRR.

Useful churn reason groups

  • Voluntary cancellation
  • Payment or renewal failure
  • Downgrade or contraction
  • Product inactivity
  • Business closure or duplicate account
