Quantity Churn Rate charts the rate at which your customers cancel subscriptions or reduce their number of seats or licenses over time.
TL;DR
Quantity Churn Rate charts the loss of subscriptions (rather than customers or revenue) over time.
For companies that sell individual licenses or seats, Quantity Churn Rate tracks the loss of these licenses or seats. For companies that don’t, Quantity Churn Rate tracks the loss of whole subscriptions.
Subscriptions vs. Subscription Quantity
If your company sells individual licenses or seats, it’s important to understand the difference between Subscriptions and Subscription Quantity.
Subscriptions are specific instances of plans your customers have subscribed to, whereas Subscription Quantity is the number of these subscriptions.
For example, Syncalytics subscribes to four Gold plans and five Silver plans. They have two subscriptions (1 × Gold + 1 × Silver) with a subscription quantity of nine (4 × Gold + 5 × Silver).
If your company doesn’t sell licenses or seats (or your billing system doesn’t support subscription quantities), then Quantity Churn Rate will represent the rate at which you lose whole subscriptions.

Calculation
Standard Formula (B2B)
Formula
Example
At the start of the month, your customers have ten active subscriptions. During the month, you lose two subscriptions: one from an existing customer and one from a new customer who purchased the subscription that month. Your quantity churn rate is 10%: 1 ÷ 10.
Shopify Formula (B2C)
Formula
Example
At the start of Monday, you have 100 active subscriptions. That day, you lose five subscriptions. The next day, you gain another ten but lose five, leaving you with 100 subscriptions at the end of Tuesday.
The quantity churn rate for this period is the sum of each day’s quantity churn rate:
- Monday’s quantity churn rate: (100 − 95) ÷ 100 = 5%
- Tuesday’s quantity churn rate: (95 − 100) ÷ 95 = −5.26%
The quantity churn rate for Monday – Tuesday is −0.26%. A negative quantity churn rate indicates you’re gaining new subscriptions faster than losing them.
