A NAT service plan consists of bandwidth resources and one or more public IP addresses. When you use a NAT service plan, you are charged a rental fee for the public IP addresses and a data transfer fee.

Billing methods

NAT service plans support the pay-as-you-go billing method. You are charged and billed on an hourly basis. If the usage duration is less than 1 hour within a billing cycle, the usage duration is rounded up to 1 hour.

Billable item

When you use a NAT service plan, you are charged a rental fee for the public IP addresses and a data transfer fee. The fees are calculated based on the following formulas:
  • Rental fee = Unit price × Number of public IP addresses × Duration

  • Data transfer fee = Unit price × Amount of outbound data transfer

    • You are charged only for outbound data transfer (from Alibaba Cloud to the Internet). You are not charged for inbound data transfer.

    • The unit price for outbound data transfer is fixed and does not vary with the maximum bandwidth of the NAT service plan. We recommend that you set the maximum bandwidth based on your business requirements. This helps you prevent unnecessary costs that may be caused by malicious requests or service malfunction.
