Subscription Economics Calculator
The three numbers that decide whether a subscription business works: MRR, how long subscribers stay, and what each one is worth.

- Monthly churn
- Gross margin
How to use this calculator
- Enter active subscribers, price per month, monthly churn, and gross margin.
