Why NRR above 100% matters so much
Net revenue retention above 100% means your existing customers grow their spending faster than you lose revenue to churn and downgrades. The business grows even if you do not sign a single new customer. That compounding is why investors look at NRR so closely, and why public SaaS companies with high NRR have historically traded at higher revenue multiples than peers with low NRR.
How NRR and GRR are calculated
- NRR = (starting MRR + expansion - contraction - churn) / starting MRR.
- GRR = (starting MRR - contraction - churn) / starting MRR.
Only count revenue from customers who were in the cohort at the start of the period. Revenue from new customers belongs in your new MRR, not in retention.
Frequently asked questions
What is the difference between NRR and GRR?
Gross revenue retention ignores expansion, so it can never go above 100%. Net revenue retention includes expansion and can exceed 100% when upgrades outpace churn and contraction.
Should I measure NRR monthly or yearly?
Annual NRR is the standard figure for benchmarks and investor updates. Monthly NRR is useful for spotting changes early, but it is noisier.
