Calculate your recurring revenue
Monthly and annual recurring revenue are the headline metrics of a subscription business. This calculator computes MRR and ARR from your subscription price and billing cadence, so you can state your recurring revenue consistently.
Why normalising to MRR matters
Subscriptions bill on different cadences, monthly, annually, and comparing or summing them requires a common measure, which is MRR, monthly recurring revenue. An annual plan is normalised to its monthly equivalent so all subscriptions can be added together and tracked over time. ARR is simply MRR times twelve, the annual view. These metrics matter because recurring revenue is predictable and valued highly, and stating it consistently, all normalised to the same cadence, is what makes growth trackable and comparable. Mixing cadences without normalising gives a misleading total.
A planning estimate
This is an estimate for planning from the figures you enter, not financial or business advice. Real outcomes depend on factors beyond any single calculation, so treat the result as a guide. The calculation runs entirely in your browser, so your figures are never uploaded and stay on your own machine, which matters for business numbers you would not want to share.

Frequently Asked Questions
What are MRR and ARR?
Monthly and annual recurring revenue: the normalised recurring revenue of a subscription business. ARR is MRR times twelve.
Why normalise to MRR?
Because subscriptions bill on different cadences, so an annual plan is converted to its monthly equivalent to add all subscriptions together consistently.
How is an annual plan counted in MRR?
As its monthly equivalent, the annual price divided by twelve, so it can be summed with monthly plans on a common basis.
Why does recurring revenue matter?
Because it is predictable and valued highly. Stating it consistently as MRR or ARR makes growth trackable and comparable over time.
