MRR (Monthly Recurring Revenue)

The total predictable revenue your subscription business earns every month — the heartbeat metric that tells you how big, and how fast-growing, the recurring side of the business really is.

In plain English

MRR is the sum of all the recurring subscription fees you can count on collecting in a given month. If a customer pays you €120 every month, they contribute €120 of MRR; if another prepays for a year, you spread their annual fee across twelve months. The point of MRR is to strip out the noise — one-off setup fees, consulting, refunds — and leave only the steady, repeatable revenue that lets you forecast and plan. It's the number most SaaS founders watch every single morning, because a clean MRR figure tells you instantly whether the business is growing, flat, or shrinking.

The formula

MRR = Active customers × ARPA (avg revenue per account / month)

Always exclude one-time fees — setup charges, professional services, and non-recurring overages don't belong in MRR because they won't reliably repeat next month.

A worked example

Say you have 400 active customers, and each pays an average of €120 per month (your ARPA). Multiply the two together.

MRR = 400 customers × €120 = €48,000

So you're booking €48,000 of recurring revenue every month. If twenty new customers join next month at the same ARPA, you'd add €2,400 of new MRR and climb to €50,400 — and that delta, not the absolute number, is what really moves the needle.

What's a good MRR?

There's no single "good" MRR value — a €48,000 figure could be excellent for a young startup or worrying for a scaled company. What actually matters is how fast MRR is growing month over month, so benchmark the growth rate instead:

Monthly MRR growthVerdictTypical context
15–20%+ExcellentEarly-stage, strong product-market fit
10–15%HealthyCommon early-stage target
5–10%SolidScaling past €1M ARR
< 5%SlowingWatch for plateau or churn drag

As you scale, sustaining high percentage growth gets harder simply because the base is bigger — so a "good" growth rate naturally moderates over time. Pair the growth number with churn to see whether growth is coming from new wins or just outrunning losses.

Frequently asked questions

What counts toward MRR?
Only recurring subscription revenue, normalised to a monthly figure. Include monthly fees and the monthly equivalent of annual plans. Exclude one-time charges like setup fees, professional services, and usage overages that don't recur predictably.
Is there a good MRR number to hit?
No single MRR figure is good or bad on its own — it depends entirely on your stage and costs. What investors and operators watch is the month-over-month growth rate. Early-stage SaaS aiming for 10 to 20 percent monthly growth is considered healthy.
What's the difference between MRR and ARR?
They measure the same recurring revenue over different windows. MRR is the monthly figure; ARR is the annual figure, equal to MRR multiplied by 12. Monthly-billed businesses usually lead with MRR, while annual-contract businesses lead with ARR.
