Gross revenue retention, or GRR, measures how much existing recurring revenue remains after churn and contraction, before expansion revenue is added back.
Formula
GRR = (Starting revenue - Churn - Contraction) / Starting revenue
GRR helps reveal whether NRR is supported by a stable customer base or masked by a few expansions. Use it with SaaS net revenue retention benchmarks.
