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
