What is net revenue retention?
Also known as: NRR, Net dollar retention, NDR
Net revenue retention (NRR) is the percentage of recurring revenue retained from existing customers over a period, including expansion, contraction, and churn, but excluding new customer revenue. NRR above 100% means existing customers grew enough to more than offset all losses.
Formula
How to calculate net revenue retention
NRR = ((Starting MRR + Expansion − Contraction − Churn) ÷ Starting MRR) × 100- Starting MRR
- Monthly recurring revenue from existing customers at period start
- Expansion
- Additional revenue from upsell, cross-sell, and seat growth
- Contraction
- Revenue lost to downgrades and seat reductions, without full cancellation
- Churn
- Revenue lost to full cancellations
Worked example
Starting MRR is $500,000. Expansion adds $60,000, contraction removes $15,000, churn removes $25,000. NRR = (($500,000 + $60,000 − $15,000 − $25,000) ÷ $500,000) × 100 = 104%.
Benchmarks
Typical net revenue retention ranges
Commonly reported ranges for B2B SaaS. Treat these as orientation — your own segment and contract structure matter more than any cross-industry figure.
| Segment | Typical range |
|---|---|
| Best-in-class enterprise SaaS | 120%+ |
| Healthy B2B SaaS | 105–115% |
| SMB-focused SaaSExpansion is structurally harder with smaller accounts | 90–100% |
| ConcerningGrowth becomes dependent on ever-increasing acquisition spend | Below 90% |
In practice
What you need to know about net revenue retention
Why NRR is the metric investors care most about
NRR compounds. At 120% NRR, a cohort’s revenue grows without acquiring a single new customer, which means growth is not gated on sales spend. At 90%, every dollar of new revenue must first refill a leaking bucket. Two companies with identical top-line growth and different NRR have fundamentally different economics, and valuation multiples reflect that gap.
NRR can hide a retention problem
A handful of large expansions can lift NRR above 100% while the majority of accounts shrink or leave. Always read NRR alongside gross revenue retention and logo retention. If GRR is weak and NRR is strong, your growth rests on a few accounts — a concentration risk, not a retention win.
Choose your cohort definition and hold it
NRR is highly sensitive to how you define the starting cohort and whether you measure monthly-annualized or trailing-twelve-month. Both are defensible; switching between them mid-year is not. Document the definition and keep it stable so the trend stays meaningful.
How to improve it
Improving net revenue retention
Find expansion signals in conversations, not just usage
Seat-limit warnings show up in product data, but a new team wanting access, a new use case, or a budget cycle opening up shows up in meetings and email first. That is where most expansion pipeline is lost.
Attack contraction separately from churn
Downgrades and cancellations have different causes and different fixes. Contraction often signals partial value realization — some teams succeeded, others did not — which is recoverable if caught early.
Align on account expansion ownership
NRR suffers when nobody clearly owns expansion. Whether it sits with CS, sales, or a hybrid, the ambiguity itself costs more than either choice.
FAQ
Net revenue retention questions, answered
What is a good NRR?+
Above 100% is the threshold for durable growth, meaning existing customers more than replace all losses. 105–115% is considered healthy for B2B SaaS, and 120%+ is best-in-class for enterprise. SMB-focused companies commonly sit at 90–100% because smaller accounts offer less room to expand.
What is the difference between NRR and GRR?+
Gross revenue retention excludes expansion, so it can never exceed 100% and measures purely how well you hold onto existing revenue. NRR includes expansion and can exceed 100%. GRR shows the size of the leak; NRR shows whether growth from existing accounts outruns it.
Does NRR include new customers?+
No. NRR measures only revenue from customers who existed at the start of the period. Including new customer revenue would conflate acquisition performance with retention performance and make the metric useless for judging either.
Can NRR be above 100% while the business is unhealthy?+
Yes, and this is a common trap. If a few large accounts expand aggressively while many small accounts churn, NRR can look strong while the customer base erodes. That is why NRR should always be read next to GRR and logo retention.

Gross revenue retention
Gross revenue retention (GRR) is the percentage of recurring revenue retained from existing customers over a period, counting churn and contraction but excluding all expansion. GRR can never exceed 100%.
Churn rate
Churn rate is the percentage of customers who stop paying for a product during a given period. It is calculated by dividing the number of customers lost during the period by the number of customers at the start of that period.
Expansion revenue
Expansion revenue is additional recurring revenue generated from existing customers through upsells, cross-sells, seat additions, or tier upgrades. It is the component of net revenue retention that allows NRR to exceed 100%.
Customer retention rate
Customer retention rate is the percentage of customers you keep over a given period, excluding new customers acquired during that period. It is the complement of customer churn rate.
Monthly recurring revenue
Monthly recurring revenue (MRR) is the predictable revenue a subscription business expects to receive every month, normalized to a monthly figure. It excludes one-time charges such as setup fees, professional services, and overages.
Annual recurring revenue
Annual recurring revenue (ARR) is the value of a subscription business's recurring revenue normalized to a one-year period. It is the standard headline metric for B2B SaaS companies selling annual contracts.
