Calculate your baseline first
ARR = ending MRR × 12. This is an annualized recurring revenue run-rate based on the monthly recurring revenue after new, expansion, contraction and churn movements.
Net revenue retention compares retained and expanded revenue from the starting customer base against starting MRR. In this calculator, NRR = (starting MRR + expansion MRR − contraction MRR − churned MRR) / starting MRR × 100.
No. New-customer MRR contributes to ending MRR and ARR, but NRR focuses on revenue retained from the existing customer base. That separation helps you see whether growth is coming from acquisition or retention/expansion.
Results are estimates generated locally in your browser from the values you enter. ARR is an annualized run-rate and may differ from GAAP revenue, bookings, billings, deferred revenue or cash collections.
