ARR formula: convert monthly recurring revenue to ARR
Turn MRR into an annual recurring run rate, with a worked example and checks for one-time revenue.

How is ARR calculated from MRR?
This tool annualizes monthly recurring revenue: ARR = MRR × 12. The result assumes the entered recurring base represents a sustained monthly run rate. It is not a promise that the business will collect that amount in the next year.
A straightforward ARR example
An illustrative subscription business has $42,000 MRR. Multiplying by twelve gives $504,000 ARR. If $6,000 of the monthly figure was actually non-recurring implementation work, eligible MRR is $36,000 and the corresponding annual run rate is $432,000.
The $72,000 difference comes entirely from input classification. Before entering the amount, reconcile the recurring base to plan prices, recurring add-ons, and the reporting policy used by your team. Keep one-time consulting, setup fees, and hardware sales outside this particular calculation.
Use a consistent snapshot
Suppose MRR rises from $36,000 in January to $42,000 in June. The June snapshot annualizes to $504,000. It does not retroactively turn every earlier month into a $42,000 month.
Record the snapshot date with the result. Comparing January ARR with June ARR is a comparison of recurring-revenue states. Comparing either snapshot with actual year-to-date revenue is a different analysis requiring the individual monthly figures.
ARR questions
What is the difference between ARR and annual revenue?
Annual revenue describes revenue over a period under your accounting policy. This calculator multiplies one recurring monthly amount by twelve. Non-recurring sales, changing subscription levels, and recognition timing can make those numbers differ.
Can I divide ARR by twelve to get MRR?
Yes, for an ARR value built using this same simple annualization. $504,000 ÷ 12 gives $42,000. Do not assume a differently defined contracted-revenue metric can be converted without checking its definition.
Does the tool include future churn?
No. Update the entered recurring base or build a monthly schedule if you want to examine cancellations, new customers, or expansion. The multiplication itself does not forecast any of them.
Use the arr calculator to reproduce the scenario with your own inputs.
