Annual Recurring Revenue Calculator

Annualize a current monthly recurring revenue run rate without assuming future growth or retention changes.

Use this to convert an established MRR snapshot to an annual run rate. Use MRR first if you only have customers and monthly pricing.

Your inputs

Use consistent units and a matching period throughout. Enter decimals with a dot or comma, without thousands separators.

Normalized recurring monthly revenue at one snapshot date, excluding nonrecurring charges.

Your result

Result for the default inputs

147,000.00

Calculations run in this browser. Inputs are not sent to a server or added to a share link.

What the result means

ARR expresses the current recurring monthly base over twelve months. It is a run-rate metric, not booked annual contract value, historical annual revenue, or a forecast of the next year.

The formula

Monthly recurring revenue * 12

Results are displayed to at most two decimal places. Calculations use the unrounded inputs.

A worked example

Put the formula to work

Current monthly recurring revenue (currency per month)
12,250

ARR (input currency per year, run rate): 147,000.00

MRR of 12,250 annualizes to an ARR run rate of 147,000.

How to use this calculator

  1. Confirm the source MRR uses a recurring-only revenue policy.
  2. Take the MRR total at a clearly stated snapshot date.
  3. Multiply by twelve and label the result as an annualized run rate.

Why this number matters

Annualizing the recurring base provides a common scale for subscription businesses without confusing different billing frequencies.
