Net revenue retention %
Ending ARR ÷ starting ARR × 100 when you define expansion and churn in dollars—mirrors RevOps exports without cohort SQL.
Example scenario
A SaaS customer-success review starts from $428,000 in beginning MRR and tracks $92,000 in expansion and upsell dollars against $38,000 in churn plus contraction over the same measurement window. Ending recurring revenue nets to $482,000, producing net revenue retention of approximately 112.62% when measured as ending divided by starting on the installed base. Teams use this ratio to judge whether existing customers are expanding faster than revenue leakage across downsells and cancellations.

How to use the net revenue retention %
- Input starting MRR or ARR ($) for the qualifying installed-base cohort at period open, aligned to your RevOps segment definition.
- Enter expansion and upsell ($) booked from existing customers in the window, excluding brand-new logo acquisition unless your policy routes it here.
- Add churn and contraction ($) for cancellations, downsells, and seat reductions tied to the same cohort logic.
- Read net revenue retention (%) alongside ending recurring revenue to compare scenarios for save plays, pricing tests, and adoption initiatives.
Net revenue retention benchmarking context
- Above-100% NRR interpretation
- Net revenue retention above 100% indicates that expansion within the retained installed base outpaced revenue lost to churn and contraction in the modeled window.
- Cohort definition discipline
- Comparable NRR reporting requires consistent rules for which accounts qualify as starting cohort revenue and how expansion from cross-sell products is attributed.
- NRR versus GRR distinction
- Net retention incorporates expansion and contraction, while gross retention focuses on logo and revenue retention without expansion uplift, making each metric answer different planning questions.
Best use cases
- Forecasting and scenario planning
- Client education and pre-qualification
- Budget and performance decision support
Frequently asked questions
Should starting MRR be ARR or MRR in this calculator?
Use one recurring-revenue basis consistently. If you input ARR as the starting point, keep expansion and churn dollars on an annualized basis too so the ratio is dimensionally consistent.
Does net revenue retention include new customer acquisition revenue?
Standard NRR definitions focus on the existing customer base. New logo bookings are typically excluded so expansion quality from current customers is visible.
How is this different from gross revenue retention (GRR)?
NRR includes expansion and upsell in the numerator path. GRR measures how much starting revenue you retain after churn without giving credit for expansion, so it usually sits at or below 100%.
Why might my BI tool’s NRR differ slightly from this output?
Timing of recognized revenue, FX translation, credits, and cohort eligibility rules can shift dollars versus a simplified bridge. Align inputs to the same export your finance team certifies.
