Is NRR the same as Dollar Retention?

Yes — Net Dollar Retention (NDR) and Net Revenue Retention (NRR) are used interchangeably. Some public filings prefer NDR; the calculation is identical.

Should NRR include one-time revenue?

No. NRR is a recurring revenue metric. Professional services, one-time implementation fees, and non-recurring add-ons should be excluded to keep the number comparable across periods and companies.

How often should NRR be reported?

Monthly for internal management review, quarterly for board reporting, annually for investor updates. Trailing-12-month NRR is the standard for board decks — it smooths seasonality and matches how investors benchmark.

Net Revenue Retention (NRR): Benchmarks, Formula

Net Revenue Retention (NRR) measures the recurring revenue retained from your existing customer base over a period, including expansion.

Net Revenue Retention: The One SaaS Metric Investors Weight Above All Others

Net Revenue Retention (NRR) is the single most-cited SaaS metric in late-stage funding conversations. It answers one question: if you stopped acquiring new customers today, would your revenue grow, hold, or shrink? NRR above 100% means the existing base grows on its own. NRR above 120% — the bar for best-in-class public SaaS — means expansion is dramatically outpacing churn, and every dollar of CAC compounds. NRR below 90% is a warning sign that no amount of new logo acquisition will fix.

The formula

NRR = (Starting ARR + Expansion ARR − Contraction ARR − Churned ARR) / Starting ARR, measured over a defined cohort period (typically trailing 12 months). Expansion includes upsells, cross-sells, and seat/usage growth. Contraction includes downgrades and seat reductions. Churn is fully lost accounts. Critically, new logos acquired in the period are excluded — NRR isolates the behavior of the existing base.

Benchmarks that matter

SMB SaaS: 90-100% is normal, 105%+ is strong. Mid-market: 105-115% is normal, 120%+ is strong. Enterprise: 115-125% is normal, 130%+ is best-in-class. Companies like Snowflake, Datadog, and Twilio have historically posted NRR of 130-170% by combining low churn with consumption-based expansion. Public SaaS median has drifted from ~115% (2021) to ~108% (2024) as expansion budgets tightened.

The three levers

(1) Reduce churn — customer success motion, product stickiness, contract length. (2) Reduce contraction — proactive engagement before renewal, right-sizing conversations that reset expectations rather than surprise downgrades. (3) Grow expansion — seat expansion in existing accounts, cross-sell to adjacent products, usage-based pricing that ties revenue to customer growth. Expansion is where the highest NRR companies win — often expansion alone contributes 20-40 percentage points.

Segmenting NRR

Reporting a single company-wide NRR hides diagnostic signal. Segment by cohort year (are recent cohorts retaining better or worse than older ones?), by customer size band (SMB NRR often masks strong enterprise NRR), by product line, and by acquisition channel. When NRR trends down, the segmentation reveals whether it's a churn problem, a contraction problem, a product problem, or an ICP problem.

Gross vs Net retention

Report both. Gross Revenue Retention (GRR) excludes expansion — it's the floor of your business, showing how much revenue you keep before any upsell activity. GRR of 90%+ is table stakes for enterprise SaaS; 85%+ for mid-market; 75%+ for SMB. NRR without GRR context can hide serious churn masked by aggressive expansion — a company with 130% NRR and 75% GRR has a leaky bucket the expansion team is refilling faster than it drains.
