Monthly Recurring Revenue (MRR)

Monthly recurring revenue (MRR) is the normalised monthly value of recurring subscriptions from active customers.

MRR is a business metric used by SaaS, membership and subscription businesses. It turns subscriptions with different billing periods into one comparable monthly amount, helping a business see the size and movement of its repeatable revenue base.

MRR is not the same as cash received, invoices issued or accounting revenue recognised for the month. It is a non-IFRS operating metric, so the business needs a clear, consistent calculation policy.

Where Monthly Recurring Revenue Appears

You may see MRR in:

MRR is especially useful when a business bills some customers monthly and others quarterly or annually, because each recurring contract is converted to a monthly value.

How To Calculate MRR

The basic formula is:

MRR = Sum of each active subscription’s monthly recurring value

For example, an annual subscription worth $1,200 contributes $100 to MRR when normalised over 12 months. A monthly subscription worth $80 contributes $80.

MRR normally includes recurring subscription charges and recurring upgrades. It normally excludes one-off setup work, implementation fees, hardware, professional services, free trials and other non-recurring sales. The business should document how it treats discounts, credits, refunds, paused accounts, overdue subscriptions, usage charges and foreign currencies.

The SaaS Metrics Standards Board’s recurring-revenue guidance explains the related annualised measure and the common relationship:

ARR = MRR × 12

That shortcut works only when MRR and ARR use the same scope and policy.

Simple Example

A software business has:

  • 40 customers paying $50 per month
  • 10 customers paying $100 per month

Its MRR is:

(40 × $50) + (10 × $100) = $3,000

If the business also earns a one-off $2,000 implementation fee, that fee can be real accounting revenue without being MRR. Keeping it out of MRR preserves the metric’s focus on recurring subscriptions.

How MRR Changes

A useful monthly bridge is:

Opening MRR + New MRR + Expansion MRR − Contraction MRR − Churned MRR = Closing MRR

  • New MRR comes from new customers.
  • Expansion MRR comes from upgrades or added seats.
  • Contraction MRR comes from downgrades.
  • Churned MRR is lost when subscriptions end.

Tracking those movements explains why MRR changed instead of showing only the closing total.

MRR Versus Accounting Revenue And Cash

A customer may pay $12,000 upfront for a one-year service. The contract may contribute $1,000 to MRR, while the $12,000 cash arrives immediately. In the accounts, deferred revenue and revenue recognition determine when the amount becomes revenue.

IFRS 15 focuses on recognising revenue as promised goods or services transfer to the customer. MRR does not replace that accounting treatment.

Why Monthly Recurring Revenue Matters

MRR gives subscription businesses a short-cycle view of recurring growth. It can support pricing, hiring, sales planning, retention work and forecasts.

It can also mislead if the policy changes or one-off revenue is included. Use the same definitions each month and reconcile the metric to subscription records, invoices and accounting revenue.

How Gimbla Can Help

Gimbla can keep the accounting side of subscription activity clear through invoices, payments, bank reconciliation, tax settings and financial reports. MRR can then remain a separate operating metric while the books show what was billed, collected, deferred and recognised.

In Short

MRR is the normalised monthly value of recurring subscriptions. It is useful for managing a subscription business, but it remains distinct from cash, billings, deferred revenue and recognised accounting revenue.
