This document describes the instance adjustment fees of TencentDB for SQL Server.
Billing Mode for Upgraded Instances
For yearly/monthly subscription instances, when a user self-upgrades a database instance, the system calculates the price difference between specifications and deducts it from the user's account. If the account balance is insufficient, you need to recharge first. The upgrade will be billed according to the new specifications.
When a pay-as-you-go instance is upgraded, it will be billed according to the new specifications in the next billing cycle.
Billing Mode for Downgraded Instances
Explanation of Downgrade Fees
For yearly/monthly subscription instances, when a user self-downgrades a database instance, the system calculates the price difference according to the following formula:
Refund amount = Remaining value of the original configuration - Purchase value of the new configuration
The explanation of the monetary value is as follows:
Remaining value of the original configuration: The effective order amount of the original configuration minus the used value of the original configuration.
The effective order amount of the original configuration: The amount paid for orders that are in effect, excluding discounts and vouchers.
The consumed amount for the original configuration: Calculated based on the following rules:
For the used part, if the usage has lasted for a full month or longer as of the day when downgrading is initiated, charges will be deducted by the month. If not, charges will be deducted on a pay-as-you-go basis.
The usage is precise down to the second.
Purchase value of the new configuration: The current official price of the new configuration multiplied by the remaining usage duration.
Note:
Deductions or vouchers will not be refunded.
The refund will be returned to your Tencent Cloud account proportionally based on the ratio of cash and bonus funds used for the purchase.
If the refund amount is ≤ 0, it will be calculated as 0, meaning the refund amount is 0.
Pay-as-You-Go
For pay-as-you-go instances, when a user downgrades a database instance, the system recalculates the billing based on the new configuration.
Downgrade Fees Calculation Example
Note:
The prices used in the examples below are only for demonstration purposes and do not correspond to the actual prices on the official website. The actual unit prices shall prevail, which may vary by region, campaign, or policy.
Background
The dual-server high-availability edition instance with the specs of 1 core, 4 GB memory, 10 GB storage space in Beijing Zone 5 will be billed at the rate of 0.26256 USD/Hour.
The instance has been used for 24 hours, and you want to downgrade it to the specs of 1 core, 2 GB memory, and 10 GB storage space.
Billing
Pay-as-you-go fee per hour = memory specification fee + storage fee.
The first 24 hours will be billed at the rate of original specification. Fee per hour = 4*0.0651 USD/GB/Hour + 10*0.000216 USD/GB/Hour = 0.26256 USD/Hour.
For the instance downgraded to the specs of 1 core, 2 GB memory, and 10 GB storage after 24 hours, it will be billed according to the new specifications in the next billing cycle.
New specs fee per hour = 20.0651 USD/GB/Hour + 10*0.000216 USD/GB/Hour =0.13236 USD/Hour.
