Net revenue retention (NRR): how to calculate it and what a good rate is

Net revenue retention, defined

This page is part of SaaS metrics. Net revenue retention, usually shortened to NRR, measures the percentage of recurring revenue kept from a group of customers over time, after expansion, contraction and churn⁵. It is the one retention number that includes upgrades. A customer who cancels pulls it down. A customer who buys more pushes it up.

The metric travels under other names. Net dollar retention (NDR) and net MRR retention are common synonyms⁵, and public companies often write “dollar-based net retention rate”³. In an investor update, treat any of them as the same idea with a company-specific recipe attached.

Retention can be measured over any time period, but 12 months is the common choice, because that window works for both annual and monthly subscriptions⁵. Everything below uses 12 months unless it says otherwise.

How analysts rate NRR in your industry

Analysts rate a net retention rate against an industry benchmark, and it is only worth quoting next to one with the same recipe and the same kind of company. Snowflake monitors a dollar-based net revenue retention rate to measure the growth of existing customers², and benchmarking against public SaaS companies is of limited use for private ones because of the difference in scale⁴. That is why industry surveys group private companies by contract size⁴.

How to calculate net revenue retention

NRR is a cohort measure. The cohort is every customer you had at the start of the period³. You then ask what that same group pays at the end. Customers who joined during the period are left out of the end figure³.

1. Fix the start date. Pick the day a year ago and list every paying customer on it, with each one's recurring revenue³.
2. Total the starting revenue. This is the denominator, often called Prior Period ARR in filings³.
3. Total today's revenue from that same list. Include expansion, subtract contraction and cancellations, and exclude any customer who joined later³.
4. Divide. The current total divided by the starting total gives the point-in-time rate³.

The same arithmetic can be written from the movements instead of from two snapshots. Start with the opening revenue, add expansion, subtract contraction and churn, then divide by the opening revenue⁶. Tools that track every change usually work this way, because rebuilding a year-old cohort from scratch is harder than summing the movements in between⁵. One edge case is worth knowing: a customer who churns and then reactivates inside the window appears as two separate events, not as a net zero⁵.

Stripe’s version of the formula takes the beginning recurring revenue, subtracts revenue lost to churn and downgrades, adds revenue from upgrades, and divides by the beginning figure⁶. The period is your choice: NRR can be calculated on a monthly, quarterly, or annual basis⁶. Keep the interval the same from one report to the next, or the numbers cannot be compared⁵.

What counts as revenue

Use recurring revenue only. In the SaaS Capital survey, NRR is December MRR from customers who were also customers the December before, divided by total MRR in that earlier December⁴. The result can be anything from 0% to well above 100%, because it includes upsells, new product cross-sells, and price increases⁴. The method should follow a cohort over time for consistency⁴.

SaaS NRR calculation example

Two published examples show the arithmetic. The first is monthly. A company starts January with $100,000 in recurring revenue from existing customers⁶. During the month it loses $5,000 to churn, loses $2,000 to downgrades and gains $8,000 from upgrades⁶. The formula is NRR = [($100,000 - $5,000 - $2,000 + $8,000) / ($100,000)] x 100⁶. That is $101,000 over $100,000, or 101%⁶.

The second is annual. A company had four paying customers a year ago, with a total MRR of 770⁵. Some churned, contracted or expanded, and the same group now pays 800⁵. To find NRR, divide 800 by 770, which is 103.9%⁵.

Both results sit above 100%, and both follow one cohort. A customer who arrived after the start date would not change either figure^{3, 5}.

NRR vs GRR: expansion is the difference

Gross revenue retention (GRR) is the same formula with the upside removed: it excludes upsells, cross-sells and price increases, it can never exceed 100%, and 95% gross retention equals 5% churn⁴.

Net retention adds the positive effect of upsells to gross retention, so it is always higher than gross retention⁴. Because expansion only ever adds, NRR is never below GRR⁵. The two answer different questions. NRR asks whether revenue from existing customers is growing overall. GRR asks how much revenue would be kept with zero expansion⁵.

Stripe, a payments vendor, calls GRR the most honest indicator of long-term sustainability. That is a vendor’s view and not a standard, but the reason holds up: NRR can mask a retention problem if efforts to grow revenue among existing customers are especially successful⁶. A company can report a healthy NRR while it loses customers, so read the two together.

NRR vs MRR vs ARR: a ratio against run-rates

MRR and ARR record how much recurring revenue exists at a point in time. NRR records what happens to it over a period.

MRR is the predictable revenue a company expects every month from its active subscriptions⁵. ARR is the annual run-rate revenue of subscription agreements from all customers at a point in time, calculated by multiplying MRR by 12. Both are operating metrics, to be viewed independently of revenue and not as replacements or forecasts of it³.

So MRR and ARR are stocks, like a bank balance. NRR is a ratio of two such balances, taken from the same customers a year apart³. A company can have rising ARR and falling NRR when new customers are covering for losses in the old ones.

NRR is not revenue: where ASC 606 comes in

Revenue is defined by an accounting standard, not by a dashboard. Under ASC 606, the core principle is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration it expects to be entitled to⁷. Revenue is recognized when, or as, the entity satisfies a performance obligation by transferring a promised good or service to a customer⁷.

ARR and MRR work differently: they are run-rate figures that do not represent revenue under GAAP on a monthly or annualized basis³. NRR is a ratio built from them, so it inherits the gap. An upgrade signed in March raises March ARR and lifts NRR immediately, while the revenue from it is recognized as the service is delivered. That is why NRR will not reconcile to the revenue line in the income statement, and why it should sit in your reporting as an operating metric with its own definition, next to recognized revenue and never in place of it^{3, 7}.

How public companies define it

There is no single required formula. The SEC’s 2020 guidance on key performance indicators asks that when a company discloses a metric like this, it should provide a clear definition of the metric and how it is calculated¹. It should also state why the metric provides useful information to investors, and how management uses it to monitor the performance of the business¹. If the method changes, the company should consider whether it is necessary to recast prior metrics¹. That guidance took effect on February 25, 2020¹.

The result is that two large software companies can print a number called “net retention” that is built differently.

Snowflake uses a two-year window. It takes customers under capacity contracts that used the platform in the first month of the first year, and divides their product revenue in the second year by their product revenue in the first year². A customer that stopped using the platform stays in the calculation and contributes zero revenue in the second year². Its filing reports 125% and 126% as of January 31, 2026 and 2025, respectively². Snowflake also expects the rate to decrease over the long term, as long-tenured customers become a larger share of the base².

Datadog uses a trailing average. It starts with ARR from all customers as of 12 months earlier, then measures ARR from the same customers today, including expansion and net of contraction or attrition³. It excludes new customers³. It then averages the trailing 12-month point-in-time rates³. As of December 31, 2025 the rate was about 120%³, and the filing attributes the rise to increased usage growth from existing customers³.

Snowflake itself warns that the calculation of its key metrics may differ from similarly titled metrics at other companies, analysts or investors². Before you compare your NRR with a public company’s, compare the recipe.

What counts as a good net revenue retention rate

A rate of 100% or more means a business is growing revenue from existing customers even after accounting for churn⁵. A rate above 100% generally indicates healthy levels of customer retention and revenue growth⁶. An NRR over 100% means a business can grow significantly even if it never signs a single new customer⁶.

Beyond 100%, “good” depends on who you are measured against. SaaS Capital’s advice is to benchmark by average contract value (ACV): companies that share a similar selling price have the most in common⁴. Higher net retention correlates with higher ACVs⁴.

Net revenue retention benchmarks

The published medians below come from different samples and should not be mixed.

The gap between 102% and 82% is not a contradiction. The SaaS Capital figure covers one ACV band in a survey of private companies, while the ChartMogul figure covers a wide set of subscription businesses that use its software^{4, 5}. SaaS Capital also notes that benchmarking against public SaaS companies is of limited usefulness for private ones⁴. Pick the benchmark whose price point matches yours, and say which one you used.

Why NRR is important to the business: retention compounds

Retention compounds. SaaS Capital calls revenue retention one of the most important metrics for medium- to long-term business health because of its compounding effect on growth, and the higher it is, the easier growth gets: a company does not have to refill the bucket before it adds to it⁴.

The data supports the link. In SaaS Capital’s sample of companies with more than $1 million in ARR, the median growth rate was 24%⁴. Groups with NRR of at least 110% grew faster than that median, and companies with NRR below 100% grew slower⁴. ChartMogul found that low-retention companies are three times as likely to be shrinking as they are to be growing quickly⁵.

For a board or an investor, NRR also shows where growth comes from. A high figure means a large share of next year’s revenue is already inside the customer base. A low one means new sales must replace losses before they add anything. Investors meet the figure in fundraising conversations as well as in board packages.

What can distort NRR

A single percentage hides several mechanisms, and some of them flatter it. Price increases are the quietest: NRR includes upsells, new product cross-sells and price increases, so a rise in the rate may come from pricing and not from customers using more⁴. Expansion can also hide churn. A high NRR can coexist with customers leaving, if a few large accounts grow enough to cover the losses⁶.

Age works the other way. Snowflake expects its rate to fall as long-tenured customers become a larger part of the base², and a young cohort has more room to grow than an old one. Definitions matter as much as age. Window length, the treatment of resellers and averaging all change the result: Snowflake includes end-customers under reseller arrangements in its cohorts², while Datadog takes a weighted average of the trailing 12-month point-in-time rates³. And when a company changes its method, prior periods may need to be recast so the series stays comparable¹.

How to improve net revenue retention

Our suggested order is churn first, then expansion, then ownership. Reducing churn is a key way to improve net revenue retention⁵, and some churn is a mistake and not a decision: customers should not churn through expired cards or anything else that contributes to declined payments⁵.

Expansion comes next. Upsells and cross-sells are what lift NRR above GRR, and price increases count too, so report the two separately⁴. Someone also has to own the number. NRR is usually owned by the customer success leader, though any team that touches product, sales or customer support should be involved⁵.

Treat each tactic as a hypothesis and compare the cohorts before and after any change you make. If you can fix only one thing this quarter, fix the churn you can still see in the payment data.

Where NRR sits in a board package

An investor or director usually sees NRR next to growth and burn. Keep the definition in a footnote and keep it stable. The SEC’s guidance for public companies is a useful model for private ones: a clear definition, the reason the metric is useful, and how management uses it¹. If you change the recipe, show the old and new method side by side for at least one period, as recasting prior periods does for a public company¹. The funding side of that conversation is covered in how venture rounds work.
