MRR = Active customers × Average monthly recurring revenue per customer
Use paying customers and a normalized monthly price. Convert annual contracts to a monthly equivalent before you multiply.
Monthly recurring revenue (MRR) is the normalized monthly value of active subscription revenue from paying customers. Founders and finance teams use it to track subscription run rate without mixing in one-time fees.
Count active paying subscriptions, convert each plan to a monthly amount, sum or use an average monthly price, then multiply customers × monthly price. The calculator above does the simple version when you already have those two numbers.
Ending MRR = Starting MRR + New MRR + Expansion MRR − Contraction MRR − Churned MRR
New MRR — revenue from new paying customers in the period.
Expansion MRR — upgrades and add-ons that increase recurring revenue.
Contraction MRR — downgrades that reduce recurring revenue without a full cancel.
Churned MRR — recurring revenue lost from cancellations.
Monthly recurring value = Annual contract value ÷ 12
Apply the same rule for multi-year prepay when your team reports MRR on a monthly run-rate basis.
MRR is the monthly run rate; ARR is usually MRR × 12. Use MRR for month-to-month operations and compare MRR and ARR when you annualize for planning or investor updates.
Example 1: 100 customers × US$50 per month = US$5,000 MRR.
Example 2 (movement): Starting MRR US$20,000 + New MRR US$2,500 + Expansion MRR US$1,000 − Contraction MRR US$500 − Churned MRR US$1,500 = Ending MRR US$21,500.
Use this MRR calculator to calculate monthly recurring revenue from paying customers and subscription price. Founders, SaaS operators, and finance teams use it for quick run-rate checks. Enter paying customer count and average monthly price; the result is estimated MRR. Convert annual plans to monthly equivalents first, and compare with ARR, ARPU, Churn, or LTV:CAC calculators when you need retention or acquisition context.
Active paying customers × average monthly subscription price in matching currency.
Using the default example values from the JSON seed for this tool:
Result: $20,580.00 (Monthly recurring revenue)
Snapshot MRR from paying customers × average monthly recurring price.
Convert annual deals to monthly equivalents before multiplying if you want pure MRR.
Spikes from one-time fees should not masquerade as recurring.
If annual contracts sit in ARPU unchanged, decide whether they belong converted to monthly for your definition of MRR.
Churn, ARPU/NRR tools, then CAC or payback calculators usually finish the SaaS triangle.
