# How is MRR calculated from Stripe, Polar and Lemon Squeezy?

> ShowMRR counts only active subscriptions in live mode, converts each price to a monthly amount after the discounts and coupons that apply (a yearly price is divided by 12), and adds them up. Usage-based prices, one-off payments, refunds and taxes are left out. Several providers are added only when they bill in the same currency.

Source: https://showmrr.com/solutions/how-mrr-is-calculated-from-stripe-polar-lemon-squeezy (updated 2026-11-13). ShowMRR does not audit businesses and gives no financial advice.

## The rules

- Only **active subscriptions** count; test-mode data is ignored.
- Each price becomes a monthly amount: yearly divided by 12, weekly multiplied by 52/12, after discounts and coupons.
- **Metered (usage-based) prices are skipped**, because the price alone does not say what a customer pays this month. A usage-based product shows less than its total billing.
- Customers are distinct paying customers with an active subscription.
- Several connections are summed only in the same currency. ShowMRR stores no exchange rates, so mixed currencies are refused rather than guessed.
- One-off payments, refunds and taxes are not MRR. Lifetime deals and one-time sales read as $0.

These rules are the ones on the [methodology page](https://showmrr.com/methodology). To calculate your own, use the free [MRR calculator](https://showmrr.com/tools/mrr-calculator).

ShowMRR applies the same rules to Stripe, Polar and Lemon Squeezy: active subscriptions, monthly, after discounts.

About hourly for connected providers.
