Refund rules for converting from subscription to pay-as-you-go

Refund rules

1. After you create a subscription cloud product instance, you can switch its billing method to pay-as-you-go. This lets you recover costs and use resources more flexibly. The remaining subscription fee is refunded after the conversion.

2. When you switch the billing method for a subscription Elastic Compute Service (ECS) instance, a monthly quota applies. The quota is based on your historical spending. The specific quota is displayed on the page. If you exceed the monthly quota, you cannot perform another conversion within the same month. The quota is reset on the first day of the next month. For more information about the quota, see Limits.

Refund amount calculation

Refund amount = Amount paid - Amount consumed, where:

• Amount paid, also known as the "cash amount payable for the order", is the amount paid in cash for an order. It does not include deductions from vouchers or coupons.

• The Amount consumed is calculated based on the following rules:

  Type		Calculation rule
  Elastic Compute Service (ECS) (subscription) Cloud Game Cluster Cloud Firewall	Usage duration < 30 days	(Daily unit price × Usage duration × Applicable discount for the usage duration) × 1.5
  	Usage duration ≥ 30 days	Daily unit price × Usage duration × Applicable discount for the usage duration
  Other products		Daily unit price × Usage duration × Applicable discount for the usage duration

  Parameter description

  Parameter	Description
  Usage duration	The actual usage duration of the order. Usage duration = Conversion time - Order start time. The usage duration is measured in days. A period of less than one day is counted as one day. For example: If you purchase an ECS server for one year at 12:00 on January 1, 2023 and convert it to pay-as-you-go at 14:00 on January 10, 2023, the usage duration is 10 days. If you purchase an ECS server for one year at 12:00 on January 1, 2023 and convert it to pay-as-you-go on the same day at 14:00, the usage duration is 1 day.
  Applicable discount for the usage duration	The system recalculates the best applicable discount based on the resource configuration and the actual usage duration of the order at the time of the refund.
  Daily unit price	If the original order was for a new purchase, renewal, or downgrade: Daily unit price = List price of the order / Actual subscription duration of the order If the original order was for an upgrade: Daily unit price = Daily unit price of the configuration difference = (List price of the order / Actual subscription duration of the order) × Price difference ratio of the upgrade Price difference ratio of the upgrade = (Daily unit price of the upgraded configuration - Daily unit price of the pre-upgrade configuration) / Daily unit price of the upgraded configuration. All daily unit prices in this formula are list prices without discounts. Actual subscription duration of the order = Order end time - Order start time. The duration is rounded down to the nearest whole day. For example, if you purchase an ECS server for one month at 12:00 on January 1, 2023, and the order ends at 00:00 on February 2, 2023, the actual subscription duration is 31 days.
