What is the SaaS MRR Calculator?
A comprehensive MRR (Monthly Recurring Revenue) tracking tool for subscription businesses. Enter your starting MRR, new customer MRR, expansion MRR (upgrades), contraction MRR (downgrades), and churned MRR (cancellations) — we calculate net new MRR, ending MRR, and month-over-month growth rate.
MRR is the lifeblood of any SaaS or subscription business. Understand exactly what's driving your growth (or decline), identify which components need attention, and forecast future revenue with confidence.
Everything you need to track subscription revenue
From new MRR to net growth — complete MRR analytics.
New MRR (Acquisition)
Recurring revenue from new customers acquired during the period. The fuel for growth.
Expansion MRR
Additional revenue from existing customers upgrading plans or adding seats.
Contraction MRR
Revenue lost from existing customers downgrading plans or reducing seats.
