Subscription Revenue (MRR) Calculator

Project your subscription business revenue over time. Enter subscriber count, monthly price, growth, and churn rate to model monthly recurring revenue (MRR) and see how retention changes compound month over month.

What is MRR?

Monthly recurring revenue (MRR) is the predictable revenue a subscription business earns each month: active subscribers multiplied by average monthly price. Tracking MRR alongside churn shows whether a subscription business is growing or shrinking.

Why churn matters

Churn is the percentage of subscribers who cancel each month. Even small churn compounds: at 5% monthly churn, a business loses nearly half its customers within a year without new signups. This calculator makes that compounding visible.

Frequently Asked Questions

How is MRR calculated?

Active subscribers × average monthly subscription price. The calculator also projects MRR forward using your growth and churn assumptions.

Can I model different churn rates?

Yes. Adjust churn and growth rates to compare retention scenarios side by side.
