Estimate recurring revenue from active customers

Monthly recurring revenue is a simple estimate based on active paying customers and average monthly revenue per customer. Annual recurring revenue is MRR multiplied by twelve.

Simple MRR

This first version uses customers multiplied by average monthly revenue.

ARR view

ARR is the monthly recurring revenue annualized by multiplying by twelve.

Zero is safe

Zero customers or zero average revenue produces zero recurring revenue.

No churn model

The calculator does not add churn, expansion, or new-customer assumptions.

What MRR means

MRR is a recurring-revenue planning measure for subscription or other repeatable monthly charges. It is not the same as every form of monthly revenue, especially one-time sales.

MRR and ARR

ARR in this calculator is a straightforward annualized view of MRR. It does not forecast seasonality, cancellations, price changes, or collections timing.

Keep the scope clear

Use active paying customers and a consistent average monthly revenue definition. Exclude one-time fees if you want the result to reflect recurring revenue only.

Example: $6,000 MRR

Active customers: 120 Average monthly revenue: $50 MRR: 120 × $50 = $6,000 ARR: $6,000 × 12 = $72,000
