NRR is the waterline. Above 100%, your base grows while you sleep. Below it, your sales team's first job every quarter is bailing. Net revenue retention, or NRR, measures how much recurring revenue you keep from your existing customer base over a period, after accounting for expansion, contraction, and churn, but before adding any new customers. It is expressed as a percentage of where that cohort started. NRR of exactly 100% means the existing base neither grew nor shrank on its own. Above 100%, existing customers expanded more than they churned, so revenue grows with zero new acquisition. Below 100%, the base is leaking, and new sales has to cover the leak before it produces any growth. This guide defines NRR precisely, lays out the 2026 benchmarks (which sources disagree on), and explains why which side of the 100% line you sit on changes what your sales team's job actually is.
Net revenue retention (NRR) is the percentage of recurring revenue retained from an existing set of customers over a period, including expansion revenue (upsells, seat growth, price increases) and subtracting contraction and churn, but excluding revenue from newly acquired customers. NRR above 100% means the existing base grew on its own; below 100% means it shrank.
Take the recurring revenue from a defined cohort of customers at the start of a period. At the end of the period, measure what that same cohort is now worth, including any expansion (they bought more seats, upgraded tiers, or absorbed a price increase) and any contraction or churn (they downgraded or left). Divide the ending value by the starting value.
Formula: NRR = (starting recurring revenue + expansion - contraction - churn) / starting recurring revenue, times 100. Note the denominator is only the starting cohort. New customers acquired during the period are excluded entirely, which is the whole point: NRR isolates how the existing base behaves on its own.
Gross revenue retention (GRR) is the same calculation without the expansion term. It only counts losses: GRR = (starting revenue - contraction - churn) / starting revenue. GRR is capped at 100%, since it cannot exceed what you started with.
NRR can exceed 100% because expansion is included. The gap between a company's GRR and NRR tells you how much of its retention story is expansion versus pure holding. A company with 85% GRR and 110% NRR is losing a meaningful chunk of its base but expanding the rest enough to more than compensate, which is a different risk profile than a company with 98% GRR and 102% NRR. This mirrors the logo churn versus revenue churn distinction.
Sources disagree on the median, which is worth disclosing rather than picking one figure. Commonly cited 2026 B2B SaaS figures:
| Source view | Median NRR | Notes |
|---|---|---|
| Frequently cited industry average | ~101% to 106% | Median private B2B SaaS around 101% in a 2024 dataset |
| By segment (one dataset) | Enterprise ~118%, mid-market ~108%, SMB ~97% | Larger customers expand more reliably |
| A lower-reported dataset | ~82% | Broader or lower-end population |
| Bessemer's widely used scale | 100% good, 110% better, 120%+ best | A qualitative benchmark, not a measured median |
| Top-quartile-valued companies | ~113% | Grow 13% a year with no new business |
The clear pattern across sources: enterprise-focused companies post higher NRR than SMB-focused ones, because larger customers have more room to expand and churn less. Benchmark within your segment, and when you cite an "industry NRR," name the source and dataset, since the range across them is wide.
At NRR above 100%, every dollar of new sales is additive: the existing base is already growing, so new customers stack on top of an expanding foundation. The sales team's job is pure growth contribution.
At NRR below 100%, the first job of every new dollar is compensatory: before new sales adds any growth, it has to backfill the revenue the existing base lost. A company at 90% NRR and a $10,000,000 base loses $1,000,000 a year from that base alone, and the sales team has to sell that much just to stay flat. This is why NRR is often described as the single most important SaaS metric: it determines whether your acquisition engine is building on a rising floor or a sinking one, and a low NRR quietly makes every sales target harder without anyone changing the sales plan.
The 100% Waterline: NRR of exactly 100% means your existing customer base neither grows nor shrinks on its own. Below 100%, you are bailing water: new sales must first cover the leak before adding any growth. Above 100%, the existing base grows without any new acquisition. Which side of that line you sit on determines whether new sales is additive or merely compensatory.
The practical implication for planning: before setting a new-sales target, check your NRR. If it is below 100%, the target has a hidden component, the amount needed just to offset base decline, that should be stated explicitly rather than buried in a single growth number. If it is above 100%, the sales team's contribution is cleaner to measure, since it stacks on top of a base that is growing on its own.
"NRR is the waterline. Above 100%, your base grows while you sleep. Below it, your sales team's first job every quarter is bailing."
Report NRR alongside every new-sales target, and when NRR is below 100%, separate the target into its compensatory component and its true growth component so the sales plan reflects what is actually being asked.
NRR starts at acquisition: customers acquired outside your real ICP churn faster and expand less, dragging NRR down before customer success ever gets involved.

Net revenue retention measures how much recurring revenue you keep from an existing customer cohort, including expansion and subtracting churn, but excluding new customers. NRR above 100% means the base grows on its own; below 100% means it leaks. Which side of that line you sit on changes what your sales team's job is: additive growth above the line, compensatory backfill below it. Benchmark within your segment and name your source, since reported medians range widely from around 82% to 106%. Improve NRR with an expansion motion, better onboarding, and better-fit acquisition.

Net revenue retention is the percentage of recurring revenue retained from an existing set of customers over a period, including expansion revenue and subtracting contraction and churn, but excluding revenue from newly acquired customers. Above 100% means the existing base grew on its own; below 100% means it shrank.
Take the recurring revenue from a defined customer cohort at the start of a period. At the end, measure what that same cohort is worth, adding expansion and subtracting contraction and churn. Divide the ending value by the starting value. New customers acquired during the period are excluded from the denominator.
Gross revenue retention (GRR) is the same calculation without the expansion term, so it only counts losses and is capped at 100%. NRR includes expansion and can exceed 100%. The gap between a company's GRR and NRR shows how much of its retention story is expansion versus pure holding.
Sources vary. Frequently cited industry medians land around 101% to 106%, though one dataset reports around 82%. By segment, enterprise-focused companies post higher NRR (around 118% in one dataset) than SMB-focused ones (around 97%). Bessemer's qualitative scale puts 100% at good, 110% at better, and 120%-plus at best.
Above 100% NRR, every dollar of new sales is additive growth on top of an already-expanding base. Below 100%, new sales first has to backfill the revenue the existing base lost before producing any growth. A company at 90% NRR and a $10M base must sell $1M a year just to stay flat.
Build a deliberate expansion motion for existing accounts, improve onboarding so customers reach value fast, make the product stickier in the customer's workflow, adopt usage- or seat-based pricing that grows automatically with the customer, and target better-fit customers at acquisition so they churn less and expand more.
