MRR and ARR formulas
Starting MRR
Starting customers × average MRR per customer
Net new MRR
New MRR + expansion MRR − contraction MRR − churned MRR
Ending MRR
Starting MRR + net new MRR
ARR
Ending MRR × 12
Normalize contract periods
Divide annual contract value by 12 and quarterly contract value by 3 before combining subscriptions. Keep usage or services revenue out unless it is contractually recurring.
ARR is a run rate
ARR annualizes today’s MRR. It does not predict future bookings, renewals, churn, expansion, or revenue recognition.
Model subscriptions in detail
Forecast customer cohorts, churn, expansion, billing, and cash flow in a full SaaS operating model.
SaaS MRR & ARR ModelFrequently asked
Monthly recurring revenue is the normalized recurring subscription revenue expected in one month. Exclude setup fees, services, and other one-time charges.
Multiply MRR by 12. This is a run-rate measure, not a revenue forecast, and assumes the current recurring base remains unchanged.
Net new MRR equals new-customer MRR plus expansion MRR, less contraction MRR and churned MRR.
Yes. Normalize the recurring contract value to a monthly amount. For example, a $12,000 annual subscription contributes $1,000 of MRR.
