Match this to how your data is measured: monthly MRR, a quarterly figure, or a full-year total.

Starting MRR (Existing Customers)

Expansion MRR (Upgrades & Add-ons)

Contraction MRR (Downgrades)

Churned MRR (Cancellations)

All inputs should reflect the same time period and include only existing customers, so exclude new customer revenue.

Key Takeaways

Net revenue retention measures what an existing group of customers is worth a year later, after upgrades, downgrades and cancellations, excluding anyone acquired in between.
The widely repeated 120% bar is not what the disclosures show: across public software companies the median is 109% (Meritech SaaS Comps, 2026), and private B2B SaaS sits at 102% (Benchmarkit SaaS and AI-Native Metrics, 2026).
NRR targets should move with who you sell to. Good NDR runs 100% for prosumer and SMB buyers against 110% for midmarket and enterprise, and great runs 107% to 125% across the same span (OpenView SaaS Benchmarks, 2022).
Retention and growth travel together. SaaS businesses above 100% NRR grew 49.5% over the year to March 2023, against 9.2% for those in the 60-80% band (ChartMogul SaaS Benchmarks, 2023).

What Is Net Revenue Retention (NRR)?

Net revenue retention is the percentage of recurring revenue you keep from an existing group of customers over a period, after upgrades, downgrades and cancellations. Revenue from customers acquired during that period is excluded, so the measurement follows one cohort forward rather than mixing in new business.

Above the break-even point the existing base grows without any new sales at all, which is why the metric appears in nearly every diligence pack alongside the growth rate. Companies define the cohort, the window and the denominator differently, so two published NRR figures are rarely measuring quite the same thing.

How to Calculate NRR

Start with the recurring revenue from a group of customers at the start of the period. Add expansion, then subtract contraction and cancellations from that same group, and divide by where you started. Revenue from customers won during the period is excluded.

For example, a cohort worth $100,000 MRR that adds $12,000 in upgrades, loses $4,000 to downgrades and $5,000 to cancellations ends at $103,000, giving 103,000 ÷ 100,000 × 100 = 103% NRR, which stated as churn is net revenue churn of −3%.

NRR Benchmarks and What Good Looks Like

On the scale above, Best-in-Class runs 120-126%: the top tier starts at 120% (Bessemer State of the Cloud, 2023), and 126% is the strongest figure any of these companies discloses (Meritech SaaS Comps, 2026). Across public software companies reporting the metric the median is 109% (Meritech SaaS Comps, 2026), well below the 120% bar that circulates as the standard, and the filings line up with the lower number: Snowflake at 126%, MongoDB 121%, Cloudflare 120% and CrowdStrike 115%, each from its own 10-K or 10-Q. Private companies sit lower still, at 102% for private B2B SaaS (Benchmarkit SaaS and AI-Native Metrics, 2026).

Who you sell to moves the target more than most teams expect. Good NDR is 100% for both prosumer and SMB buyers, rising to 110% for midmarket and enterprise; great NDR runs 107% for prosumer, 116% for SMB, 124% for midmarket and 125% for enterprise (OpenView SaaS Benchmarks, 2022). Price point tells the same story from another angle: median NRR runs 54% under $25 average revenue per account and 100% above $1,000, while top-decile runs 82% to 126% across those same bands (ChartMogul SaaS Benchmarks, 2023). For example, a 105% NRR is strong for a prosumer product and unremarkable for an enterprise one.

How to Improve Net Revenue Retention

NRR has two levers and they aren't equally accessible. Reducing churn and contraction protects what you already have, while expansion adds to it, and most businesses find expansion the faster of the two because it works on customers who have already chosen them.

In practice that usually means two things. The first is pricing that grows with usage or seats, so a customer's bill rises as they get more value without anyone renegotiating. The second is noticing which accounts are approaching a plan limit before they hit it. Expansion built on a weak base is fragile, though, so it's worth reading NRR next to gross retention rather than on its own.

Net Revenue Retention Calculator FAQ

GRR counts only what you lost and cannot exceed the revenue you started with; NRR adds expansion back and can. The gap between them is your expansion revenue. Read together they separate two questions: GRR asks how well you hold on to what you sold, NRR asks whether the base grows by itself. A wide gap with weak GRR means expansion is masking a retention problem.

Yes, and for healthy B2B SaaS it usually is. Above the break-even point, expansion from existing customers more than replaces everything lost to downgrades and cancellations, so the cohort is worth more a year later than it was at the start. It is much rarer at low price points: 3% of companies under $25 average revenue per account achieve negative net churn, against 47% above $1,000 (ChartMogul SaaS Benchmarks, 2023).

No. Including them measures growth rather than retention, and it will flatter any period with strong new sales. NRR follows one fixed cohort forward, which is what makes it comparable between periods and between companies. It is also the definition most published benchmarks use, so including new customers makes your figure incomparable to them.

It compounds, which is why small differences matter more than they look. For example, a cohort held at 110% NRR is worth 1.1 times its starting value after a year and about 1.61 times after five, while one at 90% falls to roughly 0.59 over the same span. The calculator above annualizes whatever period you enter so the two are comparable.

It depends on who you sell to. Good NDR is 100% for prosumer and SMB buyers and 110% for midmarket and enterprise (OpenView SaaS Benchmarks, 2022), and private B2B SaaS sits at 102% overall (Benchmarkit SaaS and AI-Native Metrics, 2026). Anything above the break-even point means the base grows without new sales, which is the threshold that actually changes how the business behaves.
