NRR Waterfall
One number, four levers. NRR headlines the metrics slide, but the waterfall underneath — expansion, contraction, churn — is where the operating story lives. Nothing leaves your browser.
Definitions used
NRR = (starting ARR + expansion − contraction − churn) ÷ starting ARR, measured on the same customer cohort — new logos are excluded by construction. GRR = (starting ARR − contraction − churn) ÷ starting ARR, capped at 100%, and it can't be flattered by one big upsell. When NRR is healthy but GRR is weak, expansion from a few accounts is papering over a leaky base — the first thing a diligence team recomputes from the raw cohort data.
