This topic describes the refund rules of Alibaba Cloud E-MapReduce (EMR) clusters.

The following table describes the refund rules for each billing method.

Billing method Description
Subscription Subscription clusters are paid in advance based on the subscription period. If you no longer need a subscription cluster, you can submit a ticket to apply for a refund.
Pay-as-you-go Pay-as-you-go clusters are billed only after they are used. Therefore, refunds are not supported.

If you no longer need a pay-as-you-go cluster, you can release the cluster at any time based on your business requirements. After you release the cluster, you are no longer charged for the cluster.
