# SaaS MRR and ARR calculator

Enter your plan mix and the month's MRR movements to get MRR, ARR run rate, a new-to-churned bridge, and quick ratio with CSV workings.

Paste a plan mix and press Compute MRR.

MRR is the normalized monthly value of your recurring plans; ARR is a run rate at twelve times MRR, not a forecast, and an annual prepay is cash in the bank this month, not this month's revenue. One-time fees ride beside the totals on purpose. The quick ratio divides gains (new, expansion, reactivation) by losses (contraction, churned); above 1 the base grows, below 1 it shrinks, and a month with no losses has no finite ratio, so the tool reports none. Caps: 200,000 characters of plan text, 2,000 plans. Everything is computed in this tab; nothing is uploaded.
