NRR and GRR calculator

Enter one period's numbers to get net revenue retention, gross revenue retention, revenue churn and, if you add customer counts, logo churn. Use the same period and currency for every field. It runs entirely in your browser.

Enter at least starting revenue, then press Calculate.

The formulas

GRR = (start - churn - downgrades) / start
NRR = (start - churn - downgrades + expansion) / start
Revenue churn = (churn + downgrades) / start
Logo churn = customers lost / customers at start
