**Churn Rate Formula**setting. Accounts opened prior to this date that had selected the Shopify formula can continue to configure this setting. All other accounts, including new accounts opened on or after August 15, 2022 use the standard formula.

ChartMogul offers two churn rate formulas depending on your business model: B2B or B2C.

Our **Standard Formula** generally works best for B2B subscription businesses. This is because the formula calculates how a given metric (e.g., number of customers, subscriptions, or MRR) has increased (or decreased) between the start and end of a period.

For B2C subscription businesses, we recommend the **Shopify Formula**. This formula calculates how a given metric (e.g., number of customers, subscriptions, MRR) has increased (or decreased) between the start and end of a period by calculating and summing together the increase (or decrease) for each day in the period.

The **Shopify Formula** is better suited for businesses that add a high volume of new customers each month — usually with little expansion or contraction MRR — and mainly offer monthly subscriptions customers can cancel at any time.
