How This Calculator Works

Use this subscription revenue tool for quick estimation, comparison, and planning intent while keeping formula assumptions visible.

Use the subscription revenue calculator to estimate MRR, ARR, lost revenue from churn, and projected next-month revenue after growth.

MRR is active customers multiplied by monthly revenue per customer. Next month adjusts customers for churn and new customers.

Formula

MRR = customers x ARPU. Next customers = current customers - churned customers + new customers.

Example Calculation

850 customers at $39 ARPU creates $33,150 MRR and $397,800 ARR.
