What is the formula for Net Revenue Retention (NRR)?

NRR = ((Starting ARR + Expansion ARR - Contraction ARR - Churned ARR) / Starting ARR) × 100%. An NRR above 100% indicates that expansion revenue from existing accounts exceeds revenue lost to downgrades and cancellations.

How does Gross Revenue Retention (GRR) differ from NRR?

GRR = ((Starting ARR - Contraction ARR - Churned ARR) / Starting ARR) × 100%. GRR strictly excludes expansion revenue and is capped at 100%. It reveals the true durability of your core customer base without upsell distortion.

What are good NRR benchmarks for SaaS companies?

For Enterprise SaaS (ACV >$50k), median NRR is 115-120%, with top-quartile exceeding 130%. For Mid-Market B2B SaaS (ACV $5k-$50k), healthy NRR is 100-110%. For B2C or high-volume SMB SaaS, NRR typically ranges between 80-95%.

What is the 'expansion hiding churn' trap?

When a company exhibits high NRR (>110%) alongside poor GRR (<80%), a few rapidly growing accounts are subsidizing heavy underlying customer attrition. If those expanding anchor accounts plateau or depart, revenue growth collapses abruptly.

Is financial or subscription data uploaded to external servers?

No. All calculations and cohort waterfall simulations execute locally within your browser's JavaScript environment. Zero financial metrics or customer numbers are transmitted.
