Billing

The following formula is used to calculate the fees for upgrading host specifications:

Upgrade fees = Total fees of the new specifications for the remaining subscription period - Total fees of the original specifications for the remaining subscription period. Total fees of the new specifications for the remaining subscription period = Monthly fees of the new specifications/30/24 × Unused hours. Total fees of the original specifications for the remaining subscription period = Monthly fees of the original specifications/30/24 × Unused hours.

For example, assume that the monthly fees of the new specifications are USD 14,400, the monthly fees of the original specifications are USD 7,200, and the host is to expire after 50 days. In this case, the following formula is used to calculate the upgrade fees: (14400/30/24 × 50 × 24) - (7200/30/24 × 50 × 24) = 12000.
