Gross Revenue Retention Calculator

Use one entity, currency, reporting interval, recurring-revenue definition, customer identity rule, and acquisition policy across every input. The customer cohort and recurring-revenue perimeter remain fixed. Expansion and new-customer revenue are excluded. Reconcile each value to the same operating records. A mathematically correct result can still be misleading when cohorts, periods, contract types, expense boundaries, or foreign-exchange conventions differ.

GRR describes downside retention before expansion; it does not show upsell, new business, profitability, or the reasons customers reduced spend. Track the metric across consistently prepared periods and explain material definition changes. Pricing, acquisitions, contract timing, annual prepayments, currency, customer consolidation, consumption revenue, one-time services, and accounting presentation can move a result without representing the same operating change.

No. This educational calculator applies disclosed arithmetic to supplied values; it is not GAAP revenue, an audit, forecast, valuation, fundraising recommendation, or investment decision. Different churn, downgrade, renewal, acquired-customer, and currency conventions can make reported GRR incomparable. Keep the source records and metric definition, reconcile changes, test alternative conventions, and obtain qualified review before using the result in a material decision.
