About this calculator

Gross revenue retention (GRR) measures how much recurring revenue a SaaS company keeps from its existing customer base over a period, using only starting revenue minus contraction (downgrades) and churn (cancellations), divided by starting revenue — critically, it excludes any upsell or expansion revenue, capping the metric at 100%. Its counterpart, net revenue retention, adds expansion back in and can exceed 100%.

SaaS finance teams and investors watch GRR as a cleaner signal of product stickiness and churn risk, precisely because it can’t be inflated by strong upselling the way net retention can. This calculator takes your starting MRR, contraction, and churn and returns the gross revenue retention percentage.
