Pay-as-you-go

Billing

A pay-as-you-go EIP is billed for two components: a data transfer fee and a configuration fee (public IP address retention fee).

• Internet data transfer fee: Charged for data transferred over the internet through an EIP. Depending on the metering method, this is either a data transfer fee or a bandwidth fee.

  • Data transfer fee: Billed per GB of actual outbound data transfer (pay-by-data-transfer method).

  • Bandwidth fee: Billed per Mbps of specified peak bandwidth, regardless of actual data transfer (pay-by-bandwidth method).

• EIP configuration fee (public IP address retention fee): The fee for retaining a public IP address.

Pay-by-data-transfer

Pay-by-data-transfer EIPs are billed hourly for outbound internet traffic. You can release the EIP at any time.

Data transfer fee per billing cycle = Data transfer unit price (CNY/GB) × Data transfer (GB)

EIP configuration fee (public IP address retention fee) = Public IP unit price (CNY/hour/IP) × Billing duration (hours) × Number of EIPs

Pay-by-bandwidth

Pay-by-bandwidth EIPs are billed based on peak bandwidth and duration. You can release the EIP at any time.

Bandwidth fee = Bandwidth unit price (CNY/Mbps/day) × [Billing duration (hours)/24] (days) × peak bandwidth (Mbps)

EIP configuration fee (public IP address retention fee) = Public IP address unit price (CNY/day/IP) × Billing duration (days) × Number of EIPs

Modify configuration

You can modify the peak bandwidth and metering method of a pay-as-you-go EIP at any time.

• Go to the EIP console. In the Bandwidth column of the target EIP, click Modify Configuration. Set a new Maximum Bandwidth, or switch the billing method by modifying Data Transfer.

• Limitation: If you change the billing method, you cannot modify the peak bandwidth again until the change takes effect.

• When the changes take effect:

  • Changes to the peak bandwidth take effect immediately.

  • Changes to the billing method take effect at 00:00 the next day (UTC+8).

• Billing: After the changes take effect, you will be billed based on the new configuration.

Change billing method

• You can switch between the pay-by-traffic and pay-by-bandwidth billing methods. The change takes effect at 00:00:00 (UTC+8) on the next day.

• Switch from pay-as-you-go to subscription:

  • You can switch a pay-as-you-go (pay-by-bandwidth) EIP to a subscription. The change takes effect immediately.

    You cannot switch EIPs protected by Anti-DDoS Origin Enterprise to the subscription billing method.

    • Procedure: In the Actions column for the target EIP, choose > Modify Instance > Switch to Subscription.

    • Billing impact: You must pay the subscription bandwidth fee for the selected subscription duration.

    • Effective time: The change takes effect immediately upon payment.

  • You cannot directly switch a pay-as-you-go (pay-by-traffic) EIP to a subscription. You must first switch the EIP to the pay-by-bandwidth method, and then switch it to a subscription.

    While a billing method change is pending, you cannot submit another request to modify the bandwidth limit.

    • Procedure: In the Actions column for the target EIP, choose > Modify Instance > Modify, and change Metering Method to Pay-By-Bandwidth. Then, in the Actions column for the same EIP, choose > Modify Instance > Switch to Subscription.

    • Effective time: The switch from pay-as-you-go (pay-by-traffic) to pay-as-you-go (pay-by-bandwidth) takes effect at 00:00:00 (UTC+8) on the next day.

• To cancel a pending billing method change for a pay-as-you-go EIP, in the Actions column for the EIP, choose > Modify Instance > Cancel Pending Order. You cannot cancel effective orders. This action cannot be undone. Proceed with caution.

Bills and usage

• Log in to the Expenses and Costs console to view the spending summary.

• To view bills for this product, go to the Bill Details page. In the product filter, select Elastic IP Address. Select a time range to view the details for your EIPs.

• To view usage, go to the EIP console, click the target EIP, and select the Monitoring and O&M tab to see its real-time bandwidth and traffic. For more detailed monitoring data, go to CloudMonitor.

• Request an invoice after paying for an order or settling a bill. Invoicing entities and tax rates.

Stop billing

A pay-as-you-go EIP still incurs a public IP retention fee when not associated with any resource. If you no longer need the EIP, release the EIP to stop billing.

• You cannot release an EIP that is locked for security reasons.

• After you release an EIP, billing stops. However, you may still receive a bill for the EIP.

  This can happen for the following reasons:

  • An EIP that uses the pay-by-data-transfer billing method is billed hourly.

    For example, if you release an EIP at 10:30:00, you will receive a bill after 11:00:00 for the data transfer fees incurred from 10:00:00 to 11:00:00.

  • An EIP that uses the pay-by-bandwidth billing method is billed daily.

    For example, if you release an EIP on January 1, 2025, you will receive a bill after 00:00:00 on January 2, 2025 for the bandwidth fees incurred on January 1, 2025.
