The calculation

Revenue retention calculator

GRR = (starting revenue − churn − contraction) ÷ starting revenue × 100. NRR adds expansion to that numerator.

How to read it

Keep the context.

Use net movements for the same starting cohort and period. Exclude new-customer revenue and reactivations. NRR may exceed 100%; GRR excludes expansion.

These calculations do not use Churnor’s customer risk model and do not predict whether an individual customer will cancel.
