Pricing
For more information, see Pricing.
Pay-as-you-go instances
The minimum charging period for a pay-as-you-go instance is one hour. After the configuration of an instance is changed, you are charged the price of the new configuration.
Subscription instances
| Configuration change | Description |
|---|---|
| Upgrade immediately |
Payment = Total fees of the new configuration for the remaining subscription period (Monthly price of the new configuration/30/24 × Unused hours) - Total fees of the original configuration for the remaining subscription period (Monthly price of the original configuration/30/24 × Unused hours). Example: The monthly price of the new configuration is USD 14,400. The monthly price of the original configuration is USD 7,200. The remaining subscription period is 50 days. The payment is calculated as follows: (14,400/30/24 × 50 × 24) - (7,200/30/24 × 50 × 24) = USD 12,000. |

Refund = Total fees of the original configuration for the remaining subscription period (Monthly price of the original configuration/30/24 × Unused hours) - Total fees of the new configuration for the remaining subscription period (Monthly price of the new configuration/30/24 × Unused hours). Example: You subscribed to a cluster for three months, during which the original configuration charged USD 3,500. You paid USD 3,000 after using coupons. After two months, the total fees of the original configuration for the remaining month are USD 1,000. The total fees of the new configuration for a month are USD 800. The refund is calculated as follows: 1000 - 800 = USD 200. Note You can be refunded for downgrading the configuration of a subscription instance,
but cannot be refunded for the entire instance. If you need to be refunded for the
entire instance, submit a ticket to make an application.

If you upgrade the configuration of an instance and then downgrade the configuration, you may get fewer refunds in the following two scenarios:
- You used discounts in the upgrade order. For example, you subscribed to the cluster for a year at a 15% discount, which means you only need to pay USD 850 to enjoy USD 1,000 worth of service. Then, a refund for downgrading the configuration is calculated based on USD 850.
- You used coupons in the upgrade order. When you downgrade the configuration of the instance, the refund of the original configuration is calculated based on the cash you paid, excluding the amount deducted by coupons. However, when you upgrade the configuration of the instance, the fees of the original configuration are calculated based on the unit price of the original configuration, including the amount deducted by coupons.
