FAQ

Frequently asked questions

How the calculation works and where its limits are.

What is Net Revenue Retention (NRR) and why is it the gold standard SaaS metric?

Net Revenue Retention (NRR) measures the percentage of recurring revenue retained from existing customers over a period, accounting for upgrades (expansion), downgrades (contraction), and cancellations (churn). An NRR >100% means the business grows organically even with zero new customer acquisition.

What is the difference between NRR and Gross Revenue Retention (GRR)?

Gross Revenue Retention (GRR) measures revenue retained without counting expansion or upsells (maximum value is 100%). It isolates product satisfaction and baseline retention. NRR includes upsells and expansion, reflecting full customer account growth.

What NRR benchmarks do venture capital and private equity investors expect?

Enterprise SaaS leaders (e.g. Snowflake, Datadog) typically report 120% to 140%+ NRR. Mid-market SaaS benchmarks average 105% to 115% NRR, while SMB-focused SaaS typically targets 90% to 105% NRR.

Is this NRR calculation official financial advice?

No. All calculations follow standard subscription revenue recognition definitions based on your entered MRR figures. Consult a CPA for ASC 606 revenue compliance.
