Hardware devices of Tencent Cloud instances can be adjusted quickly and flexibly, an important feature that makes cloud-based virtual servers easier to use than physical servers.
When your business workload expands or contracts, and you need to upgrade or downgrade the configuration of the cloud server instance, you can adjust the configuration via the console. After the fees are settled, the cloud server will immediately run according to the new configuration.
Monthly Instance Configuration Upgrade
Billing rules
The instance upgrade follows a daily differential pricing policy, upgrade cost = monthly upgrade difference × upgrade months × applicable discount. Monthly price difference for the upgrade: Unit price difference between the new and old configurations.
The upgrade cost is calculated daily:
Number of days for upgrade = resource expiration time - current time
Number of months for upgrade = number of days for upgrade / (365/12)
Applicable discount: The applicable discount is matched based on the number of months for upgrade as effective at the International Site.
Configuration upgrade does not affect the resource expiration time.
You can pay configuration upgrade fees by using your vouchers and complimentary balance (complimentary credits).
Note:
The promotional upgrade policy is consistent with the upgrade rules of the monthly instance configuration, i.e., upgrade cost = monthly upgrade difference × upgrade months × applicable discount. The applicable discount is the current effective discount. Billing examples

The prices below are examples and are not the actual prices at the International Site. For the unit price of instances, see Pricing | Cloud Virtual Machine. Background
On December 31, 2022, purchased a 2-core cloud server with 2 GB memory. The unit price for monthly subscription was 16.8 USD/month.
Example 1
On May 1, 2023, the configuration of a 2-core cloud server with 2 GB memory was elevated to a 4-core one with 8 GB memory. The unit price for this configuration is 44.8 USD/month.
The monthly upgrade price difference = 44.8 - 16.8 = 28 USD/month
Days of upgrade = 31 × 4 + 30 × 3 + 30 = 244 days
Where, 4 stands for the 4 months: July, August, October, and December, and 3 stands for 3 months: June, September, and November; and 30 stands for the 1 day subtracted from the 31 days in May.
Applicable Discount: According to the monthly subscription, you can enjoy an 88% discount if the duration of the subscription is between 6 to 11 months.
Upgrade Cost = (44.8 - 16.8) × (244 / (365/12)) × 0.88 = 197.66 USD
Monthly configuration downgrade
Billing rules
Refund amount for instance downgrade = Refund for the instance - Cost of the new specification
If the refund fees > 0, execute the configuration downgrade, and the fees will be refunded to your Tencent Cloud account through the original payment method.
If the refund fee <= 0, implement the configuration downgrade, but no refund will be provided.
If you use a discount or voucher for purchase, the discount amount and voucher will not be refunded.
The detailed logic for the instance refund is as follows:
Refund for the instance = Fees of current valid orders + Fees of future orders - Fees of consumed resources
Fees of current valid orders: The fees paid for current valid orders, excluding discounts and vouchers.
Fees of future orders: The amount paid for future orders, excluding vouchers.
Fees of consumed resources are calculated based on the following policies:
Used portion = Fees of consumed host + Fees for consumed network
Fees of consumed host: On the day the user initiates the refund, if the CVM has been used for a full month, the cost of the used months will be deducted according to the prices and discounts that are listed at the International Site for the corresponding monthly subscription; for usage less than a month, the deduction will be calculated according to the duration of the pay-as-you-go billing mode.
Used network fees: It is required to be calculated based on the billing type of the network. If the network billing type is pay-as-you-go, then the used network fee is 0; if the network billing type is bandwidth-based, then the used network fees = hourly bandwidth cost of the pay-as-you-go host × usage duration.
The usage is accurate down to the second.

Standard Type S5, a 2-core instance with 2 GB memory and a 20 GB local hard disk in Guangzhou Zone 6, excluding bandwidth, 6.02 USD/month, used a 10-USD coupon, purchased for 1 year, and enjoyed a 17% discount for monthly subscription. Discount amount is 6.02 × 12 × 0.83 = 59.96 (USD) Payment amount is 59.96 - 10 = 49.96 (USD).
The customer purchased S5 and used it for 48 hours within 5 days; then renewed it for 1 year with an 83% discount for the monthly subscription, and the actual renewal payment was 59.96 USD. Refund fees in cash = 49.96 (fees of current valid orders) + 59.96 (Fees of future orders) - 0.01 (instance price for pay-as-you-go billing mode) × 48 (hours) = 109.44 (USD).
