Billed fees = Total fees of the new configuration for the remaining subscription duration (Monthly price of the new configuration/30 days/24 hours × Remaining subscription duration x 24 hours) - Total fees of the original configurations for the remaining subscription duration (Monthly price of the original specifications/30 days/24 hours × Remaining subscription duration x 24 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 duration is 50 days. The fees for the configuration changes can be calculated by using the following formula: (14,400/30/24 × 50 × 24) - (7,200/30/24 × 50 × 24) = USD 12,000.
