ARR calculator

Convert between ARR and MRR, or calculate ARR from customers and ARPU.

What this calculator covers

Use this ARR calculator to move between annual recurring revenue and monthly recurring revenue without losing the paired run-rate view.

When customer count and ARPU are available, the calculator can also build the same ARR estimate from the operating inputs instead of a precomputed revenue metric.

Frequently asked questions

What is the difference between ARR and MRR?
ARR (annual recurring revenue) and MRR (monthly recurring revenue) express the same recurring-revenue run rate on different time scales. ARR is simply MRR multiplied by 12, so the two figures always move together.
Does ARR include one-time fees or professional services?
By convention, ARR counts only recurring contract or subscription revenue. One-time setup fees, professional services, and usage-based charges above a committed minimum are typically excluded, though practices vary by company.
Why might the displayed MRR not multiply exactly to the entered ARR?
When you enter an ARR directly, the calculator divides by 12 and rounds the displayed MRR to cents. Multiplying that rounded figure by 12 can miss the original ARR by a few cents due to cent rounding, which is expected behavior.
What does ARPU mean in the customers-and-ARPU mode?
ARPU stands for average revenue per user (or customer). The calculator multiplies customer count by monthly ARPU to produce MRR, then annualizes that figure to ARR.

Walkthrough

Visual walkthrough

ARR and MRR are the same recurring-revenue run rate expressed on different time scales, so the conversion is a straight factor of 12.

  1. 01

    Choose the starting revenue input

    $6,200.00

    The calculator can start from monthly revenue, annual revenue, or customers and ARPU and then back into the paired metric.

  2. 02

    Convert between monthly and annual run rate

    $6,200.00 × 12 = $74,400.00

    ARR is the monthly recurring revenue run rate annualized over 12 months.
