Subscription MRR Calculator
Calculate Subscription MRR metrics for ecommerce, SaaS, marketing, and operations.
This MRR (Monthly Recurring Revenue) calculator totals the predictable monthly revenue from all active subscriptions, normalizing annual and other billing periods into a monthly figure - the core metric SaaS and subscription businesses use to track growth.
Enter your subscription counts and prices at each billing tier, and the calculator returns your total MRR.
Worked Calculation Examples
| Scenario | Result | Calculation Step |
|---|---|---|
| 50 monthly customers at $29/mo + 10 annual customers at $588/yr | MRR = $1,940 | Monthly tier: 50 × $29 = $1,450. Annual tier normalized: 10 × ($588 ÷ 12) = 10 × $49 = $490. Total MRR = $1,450 + $490 = $1,940. |
| 100 customers, all on $49/mo plan | MRR = $4,900 | MRR = 100 × $49 = $4,900. |
Normalizing Different Billing Periods
Annual subscriptions must be divided by 12 to find their monthly-equivalent contribution to MRR - a $1,200 annual plan contributes $100 to MRR, the same as a $100/month plan, since MRR measures normalized monthly recurring value regardless of how often a customer is actually billed.
MRR Components: New, Expansion, Contraction, and Churn
MRR changes each month from new customer MRR (new subscriptions), expansion MRR (upgrades or add-ons from existing customers), contraction MRR (downgrades), and churned MRR (canceled subscriptions) - breaking MRR growth into these components reveals whether growth is coming from new sales or from existing customer retention and expansion.

Frequently Asked Questions
How do you calculate MRR?
Sum the monthly-equivalent revenue from every active subscription, converting non-monthly billing periods (like annual plans) into their monthly value by dividing by the appropriate number of months.
How do you convert an annual subscription into MRR?
Divide the annual subscription price by 12 to find its monthly-equivalent contribution to MRR.
What is the difference between MRR and ARR?
MRR is monthly recurring revenue, while ARR (annual recurring revenue) is simply MRR multiplied by 12 - the same underlying revenue, expressed on different time scales.

What does the Subscription MRR Calculator calculate?
Calculate Subscription MRR metrics for ecommerce, SaaS, marketing, and operations. It is designed for fast browser-based calculations without sign-up, downloads, or manual spreadsheet setup.
What formula does this subscription mrr use?
The formula is: MRR = Σ (Monthly-Normalized Revenue of Every Active Subscription). MRR emerged as the defining metric of the SaaS (Software as a Service) business model that rose to prominence in the 2000s, as software shifted from one-time perpetual licenses to recurring subscriptions - venture capital investors popularized MRR and its growth rate as the primary lens for evaluating early-stage SaaS company health, since it isolates predictable, repeatable revenue distinct from one-time sales.
