Yearly/Monthly to Pay-per-Use

After creating a yearly/monthly DB instance, you can change it to pay-per-use billing to reclaim some costs and use it more flexibly.

Suppose you bought a yearly/monthly DB instance at 15:29:16 on April 18, 2023 and changed it to pay-per-use billing at 16:30:00 on May 18, 2023. On the Billing Center > Billing page, bills information is generated as follows:

Yearly/Monthly billing: 15:29:16 on April 18, 2023 to 23:59:59 on May 18, 2023
Pay-per-use billing: 00:00:00 on May 19, 2023 - End time of pay-per-use billing. A bill was generated every hour.

The pay-per-use billing mode will be applied only after the yearly/monthly billed duration ends and auto-renew will be not in effect.

Constraints

Resources such as EIPs that are used by DB instances may not support the change with this instance. For details about their billing mode change rules and handling methods, see Table 1.

**Table 1** EIP billing mode change rules
Change	Change Description
From yearly/monthly to pay-per-use upon expiration (billed by bandwidth)	Directly change it on the console. For details, see From Yearly/Monthly to Pay-Per-Use upon Expiration (Billed by Bandwidth).
From yearly/monthly to pay-per-use upon expiration (billed by bandwidth)	Perform two steps to change it on the console: Change the EIP to pay-per-use billed by bandwidth. Change the EIP billed by traffic.

Pay-per-use billing will be applied only after the yearly/monthly billing ends.
