Net revenue retention, or NRR, is the percentage of recurring revenue you keep from a cohort of customers over a 12 month window, including expansion, after accounting for downgrades and churn.
It is one of the most watched metrics in B2B SaaS because it tells you whether your existing customer base is growing on its own.
This post defines NRR, walks through the formula with a worked example, explains why it matters for valuation, shares benchmark ranges, and clears up the most common confusion (NRR vs gross retention).
NRR meaning in one sentence
Net revenue retention measures how much recurring revenue a cohort of customers contributes today compared to what they contributed 12 months ago.
Above 100 percent means the cohort is growing without any new logos. Below 100 percent means the cohort is shrinking and new logos have to make up the gap.
NRR is sometimes called net dollar retention, or NDR. The two terms are interchangeable in most usage.
The NRR formula
NRR = (Starting ARR + Expansion - Downgrades - Churn) / Starting ARR
Each term means a specific thing.
Starting ARR. The annualized recurring revenue from a fixed set of customers at the start of the measurement period. Usually 12 months ago.
Expansion. New ARR added by those same customers through upsell, cross sell, additional seats, or price increases.
Downgrades. ARR lost from those same customers who reduced their spend (fewer seats, lower tier).
Churn. ARR lost from customers in that cohort who fully cancelled.
The cohort is fixed. New customers acquired during the period are not in the numerator or the denominator. That is what separates NRR from a pure growth metric.
A worked NRR example
Suppose 12 months ago you had 100 customers contributing $10M in ARR.
Over the year:
- 8 customers churned, taking $500K of ARR with them
- 12 customers downgraded, reducing ARR by $300K
- 30 customers expanded, adding $1.8M in new ARR
- You also signed 25 new logos worth $2.4M (this is not in NRR)
NRR = ($10M + $1.8M - $300K - $500K) / $10M = $11M / $10M = 110%
The cohort grew 10 percent on its own. The 25 new logos worth $2.4M sit on top of that for total revenue growth, but they do not factor into NRR.
If we had recognized only churn ($500K) and ignored expansion, the metric would be gross revenue retention (GRR) = 95%. More on that below.
Why NRR matters for SaaS valuation
Public market investors and growth equity firms care about NRR more than almost any other operating metric.
A SaaS company with 120 percent NRR can grow 20 percent a year without acquiring a single new customer. The cost of that growth is far lower than acquiring net new logos. The unit economics are stronger. The business is more durable.
In valuation multiples, the gap between a 100 percent NRR company and a 120 percent NRR company is often two or three turns of revenue. Same growth rate, very different multiples, because the growth quality is different.
Boards and investors ask about NRR in every quarterly review because it is the cleanest signal of product market fit and customer success motion working together.
NRR benchmarks for B2B SaaS
These ranges are directional and vary by segment.
SMB SaaS. 90 to 105 percent is common. Higher churn rates make it harder to clear 100 percent.
Mid market SaaS. 100 to 115 percent is healthy.
Enterprise SaaS. 110 to 130 percent is the bar for top performers. Long contracts, expansion seats, and multi product motions push the number up.
Top tier benchmark. Public SaaS companies that consistently report NRR above 130 percent (Snowflake at peak, Datadog, Crowdstrike in certain windows) command premium valuations.
A drop below 100 percent in any segment is a flag. It means the existing base is contracting and the entire growth engine depends on new logos.
NRR vs gross revenue retention
The two metrics use the same cohort but tell different stories.
Gross revenue retention (GRR). Measures only churn and downgrades. Cannot exceed 100 percent.
GRR = (Starting ARR - Downgrades - Churn) / Starting ARR
Net revenue retention (NRR). Includes expansion. Can exceed 100 percent.
Why both matter. NRR can hide churn. A customer base losing 20 percent of customers but expanding the remaining 80 percent by 40 percent will still post 112 percent NRR. The number looks great. The retention motion is broken.
Looking at NRR and GRR together gives a fuller picture:
- GRR = 95%, NRR = 115%. Healthy. Some churn, strong expansion.
- GRR = 80%, NRR = 110%. Churn problem masked by expansion. Fix retention.
- GRR = 95%, NRR = 100%. Stable but no expansion motion. Build one.
- GRR = 80%, NRR = 90%. The base is shrinking. Urgent.
If you only report one number externally, report NRR. If you only watch one number internally, watch both.
Common confusion about NRR
Is new logo revenue counted? No. NRR uses a fixed cohort. New customers acquired during the measurement period do not appear in the numerator or denominator.
Are pricing increases counted as expansion? Usually yes. Most companies include like for like price increases on existing contracts as expansion ARR. Be consistent.
Is professional services revenue counted? Usually no. NRR is typically a recurring revenue metric. One time services, implementation fees, and overages are excluded.
Is the time window always 12 months? Most SaaS companies use trailing 12 months. Some use a calendar year. Public companies disclose their methodology.
Why can NRR be over 100 percent if it is called retention? Because expansion is folded in. NRR is really a "net change in cohort revenue" metric, not pure retention. The name is a little misleading. NDR is more accurate.
How NRR is actually moved
Three levers, in order of impact.
Reduce churn. Cancellations are the heaviest pull on the metric. Customer success programs, health scoring, and proactive interventions reduce churn before it shows up in renewals.
Reduce downgrades. Smaller than churn but harder to spot. Customers who drop a seat or downgrade a tier rarely tell you in advance. Adoption tracking and quarterly business reviews catch this early.
Increase expansion. Whitespace mapping, multi product motions, multi team selling, and price escalators all contribute. The biggest expansion wins come from accounts where the seller has mapped the buying committee in adjacent business units, not from upsells inside the original account boundary.
A 100 percent to 120 percent NRR jump is rarely one motion. It is typically 5 percent from churn reduction, 5 percent from downgrade prevention, and 10 percent from new expansion plays.
Why NRR depends on account intelligence
NRR sits at the intersection of customer success and account expansion. Both depend on knowing the account well enough to act early.
That means a current map of stakeholders, including the new ones who joined since the deal closed. It means visibility into whitespace across business units and geographies. It means a customer success plan that ties usage and outcomes to the next renewal conversation.
Companies that lead in NRR almost always have account intelligence systems that surface this information without anyone having to dig for it. Those with weaker NRR usually have data, but it lives in slides and shared drives where nobody finds it in time.

Bring this into Salesforce with CRUSH
NRR is the output of a hundred small account decisions made every quarter. Our CRUSH platform sits inside Salesforce and keeps relationship maps, whitespace, and account plans live so customer success and account managers can see expansion opportunities and renewal risks in the same place they already work.
When the account intelligence is in the CRM, the renewal and expansion motion gets easier. The data feeding QBRs, health scores, and forecasts is the same data, updated by the same people, visible to everyone.
