This topic describes how to change the billing method of an ApsaraDB RDS for MySQL instance from subscription to pay-as-you-go.
Prerequisites
Your RDS instance uses the subscription billing method. For more information about billing methods, see Billable items.
The RDS instance is in the Running state.
NoteIf a subscription RDS instance is locked due to expiration, you must first renew the RDS instance. For more information, see Manually renew an ApsaraDB RDS for MySQL instance.
Your RDS instance does not use a phased-out instance type. For more information, see Primary ApsaraDB RDS instance types. If your RDS instance uses a phased-out instance type, you must change the instance type before you change the billing method of your RDS instance to pay-as-you-go.
Billing rules
After you change the billing method of your RDS instance to pay-as-you-go, a refund is returned based on the original payment method.
Refund = Fee actually paid - Fee for consumed resources
The fee actually paid is the money that you paid and does not include the amount that is covered by coupons or vouchers.
The fee for consumed resources is calculated based on the following formula: Fee for consumed resources = Daily fee × Consumed subscription duration × Discount for the consumed subscription duration. The daily fee is equal to the order-specific fee divided by 30.
NoteThe consumed subscription duration is accurate to days. The part that is less than one day is counted as one day.
Impacts
When you change the billing method of your RDS instance to pay-as-you-go, the workloads on your RDS instance run as normal.
The subscription billing method is more cost-effective than the pay-as-you-go billing method, and you are offered higher discounts for longer subscription durations. For long-term use, we recommend that you select the subscription billing method.
Procedure
Log on to the ApsaraDB RDS console. In the left-side navigation pane, click Instances. In the top navigation bar, select the region in which the RDS instance resides.
Find the RDS instance and use one of the following methods to go to the Switch to Pay-as-you-go Billing page:
Click Switch to Pay-as-you-go Billing in the Billing Method column.
Click the instance ID. In the Status section of the page that appears, click Convert to Pay as you go to the right of Billing Method.
Confirm the configuration of your RDS instance, read and select Terms of Service, click Pay Now, and then complete the payment.

FAQ
What do I do if a price inquiry failure occurs when I change the billing method from subscription to pay-as-you-go?
The following list describes the common causes of the failure to change the billing method:
The RDS instance resides in the classic network that is no longer available. In this case, you must change the network type of the RDS instance from classic network to virtual private cloud (VPC) and then change the billing method.
If you receive an error message indicating that your RDS instance uses a phased-out instance type and you must change the instance type before you change the billing method of your RDS instance, you must change the instance type of the RDS instance to an available instance type and then change the billing method. For more information, see Primary ApsaraDB RDS instance types.
