Table 120 Aug 2026From “Net revenue retention is a cohort definition”

How should NRR be calculated and compared across cohorts?

Table 1How should NRR be calculated and compared across cohorts?

Route	Declare	Safe reading
Formula and calculation	Starting recurring revenue, cohort eligibility, churn, contraction, expansion, exclusions, currency, and period	The result describes the starting cohort under that contract
NRR versus GRR	Whether expansion, price change, usage, reactivation, and cross-sell are included	The two rates answer different questions and are not interchangeable
Strategy and interpretation	Segment mix, account distribution, movement bridge, comparison, and next action	A high or falling aggregate is a review signal, not a complete account diagnosis
Dashboard and data requirements	Stable customer key, cohort date, product scope, revenue fields, movement event, definition version, and as-of date	A dashboard cannot repair an untraceable cohort or changed revenue basis
Cohort, segment, and B2B	Account or contract grain, buying relationship, product scope, implementation state, and maturity	A contextual NRR cut is not a universal B2B target or a company result
Checklist and review	Owner, threshold as local control, source, uncertainty, comparison, cost fields, and review date	The checklist makes the metric governable; it does not create a causal retention effect
