MRR Calculator
Add up your Monthly Recurring Revenue across every plan — monthly, annual or anything in between — with each billing cycle normalised to a single monthly number.
This free MRR calculator turns a messy mix of plans and billing cycles into a single monthly recurring revenue number. Enter each plan's price, how many customers are on it, and its billing period — monthly, quarterly or annual — and the calculator normalises everything to one comparable monthly figure.
MRR (monthly recurring revenue) is the predictable subscription revenue your business earns every month. It is the metric SaaS founders live by: it reacts immediately to new business, upgrades and churn, and it rolls up into ARR, growth rate and almost every other number investors ask about.
How to calculate MRR
To calculate MRR, work plan by plan. For each plan, normalise its price to a single month and multiply by the number of customers on it, then add every plan together. Annual and quarterly contracts are divided by their length in months so they contribute their true monthly share — a $1,200 annual plan is $100 of MRR, not $1,200.
Only count predictable subscription revenue. Leave out one-off setup fees, professional services and usage overages: they inflate MRR without being reliably repeatable, and they make your growth look healthier than it is.
MRR = Σ ((plan price ÷ term length in months) × customers on that plan)
Say 90 customers pay $22/month and 10 customers are on a $1,200/year plan. The monthly plan contributes 90 × $22 = $1,980. The annual plan contributes 10 × ($1,200 ÷ 12) = $1,000. Total MRR = $2,980, which is $35,760 in ARR.
