How to use it

Using the mrr calculator

  1. 01

    Count active subscribers

    Use paid, currently-active accounts; exclude trials and churned-but-unbilled customers.

  2. 02

    Enter the average monthly price

    Weight across plans: total MRR from each plan divided by total subscribers.

  3. 03

    Read MRR and ARR

    Track the monthly figure operationally and the annual one for planning and fundraising conversations.

Good to know

What belongs in MRR; and what does not

Recurring subscription value only. One-time onboarding fees, hardware sales, ad hoc consulting and usage spikes distort the metric’s purpose, which is to measure predictable income. Most SaaS operators track new, expansion, contraction and churned MRR separately so the headline number stays explainable.

MRR growth quality beats quantity

  • New MRR comes from brand-new customers.
  • Expansion MRR (upgrades) is cheaper to win and signals product-market fit.
  • Net new MRR = new + expansion − contraction − churned.

A company adding $10k of new MRR while losing $8k to churn is treading water despite impressive gross sales; which is why pairs like this calculator and the churn calculator belong together.

How it's calculated

The math behind this calculator

MRR = Subscribers × Average monthly price ARR = MRR × 12

Monthly recurring revenue is the normalized monthly value of all active subscriptions. With a single plan it is subscribers times price; with several plans, weight each plan’s price by its subscriber count to get the average, then multiply. ARR simply scales MRR to a yearly view, which investors use to compare companies of different billing cadences.

Assumptions & limitations

  • All subscriptions are normalized to their monthly equivalent (annual plans ÷ 12).
  • One-time setup fees, usage overages and services are excluded from MRR.
  • Counts reflect currently active subscribers.

Worked example

400 subscribers at an average of $49 per month produce $19,600 in MRR; an ARR of $235,200.

FAQ

Frequently asked questions

How do I handle annual plans?
Divide the annual contract value by twelve and count it as monthly MRR; that normalization is the whole point of the metric.
Do free users count?
No. MRR measures paid recurring revenue; freemium users contribute $0 until they convert.
Is ARR always MRR × 12?
For smooth reporting, yes. Contract-heavy businesses sometimes quote signed ARR instead, which includes future committed contracts; a different, more optimistic number.
