Net Revenue Retention (NRR) is the single most important number for SaaS valuation — it tells you whether your business grows even if you stop acquiring new customers. NRR >100% means existing customers expand faster than they churn; below 100% means you're running on a treadmill. This calculator shows NRR and GRR (Gross Revenue Retention) side by side with cited 2024 benchmarks from SaaS Capital, OpenView, KeyBanc, and Bessemer, plus a 5-year compounded projection so you can see the long-tail impact.
Churn alone tells you what you're losing. NRR tells you the net economic motion of your customer base. SaaS Capital 2024: median public SaaS NRR is 110%, top quartile 125%+. At 125% NRR, your existing customer base alone doubles every 3 years without any new acquisition. At 90% NRR, you need to replace 10% of revenue annually just to stay flat. NRR drives valuation multiples directly — every 10 points of NRR is worth roughly 0.5-1× revenue multiple at exit.
GRR (Gross Revenue Retention) excludes expansion — it tells you what you keep before any upsell. NRR includes expansion. The gap (NRR - GRR) is your expansion contribution. A healthy gap is 10-20 points (e.g., GRR 90%, NRR 110% means 20pts of expansion offset 10pts of churn). Small gap (<5 points) indicates expansion problem; large gap (>30 points) indicates extreme product-led expansion (Snowflake, Datadog territory).
SaaS Capital 2024 medians: SMB 105%, mid-market 110%, enterprise 115%, vertical SaaS 120%. Top quartile in any segment is 125%+. Below 100% NRR is challenging at any scale. Above 130% is exceptional and usually requires product-led expansion (consumption pricing, usage-based, or strong upsell motion).
Same thing — NRR and NDR are interchangeable terms. SaaS Capital and OpenView use NRR; some Bessemer materials use NDR. Both measure: (starting MRR + expansion + reactivation - contraction - churn) ÷ starting MRR. Always ×100% to get the percentage.
Because NRR compounds. At 120% NRR, $1M of starting ARR becomes $2.49M after 5 years through pure expansion (1.20^5 = 2.49). At 90% NRR, the same $1M shrinks to $590K (0.90^5 = 0.59). The non-linearity is why NRR moves valuation multiples so much — high NRR is a growth flywheel that runs without ad spend.
Yes — by reducing churn first. NRR floor = GRR. Cut churn from 10% to 5% and NRR moves up 5 points before any expansion work. Expansion features (usage-based pricing, multiple seats, add-on modules) add the second leg. Most NRR work in SMB SaaS is actually GRR work — fewer customers leaving.
High NRR (>120%) commands premium multiples because revenue compounds without reacquisition. KeyBanc 2024: every 10pts of NRR above 100% adds roughly 0.5-1× ARR multiple at exit. Public SaaS comps: companies above 125% NRR (Snowflake, Datadog, Cloudflare) trade at 15-25× ARR; below 100% trade at <5× ARR.
