The MRR formula
MRR = monthly plans + quarterly plans ÷ 3 + annual plans ÷ 12. ARR = MRR × 12.
Leave out one-time purchases, setup fees, lifetime deals, trials and refunded payments. They are revenue, but not recurring revenue.
Example
A SaaS bills $2,400 a month on monthly plans and sold $6,000 of annual plans: MRR = $2,400 + $6,000 ÷ 12 = $2,900, ARR = $34,800.
Why MRR sets the price of a SaaS
Small SaaS are priced as a multiple of annual recurring revenue. In October 2026 the median verified-revenue listing on TrustMRR asked 3.3x its annual revenue. Read the full explanation in What is MRR?, the data in our valuation multiples report, or browse SaaS for sale with $1K+ MRR.
Frequently asked questions
How is MRR calculated?
MRR is the monthly value of all active subscriptions: monthly plans count in full, quarterly plans are divided by 3 and annual plans by 12. One-off payments, setup fees, lifetime deals and refunds are excluded.
How do you convert MRR to ARR?
ARR = MRR × 12. $2,900 of MRR is $34,800 of ARR. ARR is a run-rate, not a forecast of what you will collect this year.
Should annual plans be counted in the month they are paid?
No. A $1,200 annual plan adds $100 to MRR every month of the year, even though the cash arrives at once.
What is a good MRR growth rate?
For small SaaS, any steady positive growth is above the market: only 42% of the verified-revenue listings on TrustMRR grew their revenue over the last 30 days in October 2026.
