:Change the billing method to pay-as-you-go

Billing

After you change the billing method of a Tair instance to pay-as-you-go, a refund is returned by using the method used to pay for the instance. Coupons and vouchers cannot be refunded.

The refund is calculated by using the following formula: Refund = Fee actually paid - Fee for consumed resources.

• The fee actually paid is the money that you paid and does not include the amount 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.

  Note

  The consumed subscription duration is accurate to the day. The part that is less than one day is counted as one day.

Usage notes

• When you change the billing method of a Tair instance to pay-as-you-go, the workloads on the instance are not interrupted.

  Important

  Each pay-as-you-go Tair instance is billed and paid by hour. To prevent overdue payments that may cause downtime, make sure that your account balance is sufficient.

• 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 periods. For long-term use, we recommend that you select the subscription billing method.

• Billing method switch is not available for instances that use phased out instance types.
