This topic describes the pay-as-you-go billing method of elastic IP addresses (EIPs). Pay-as-you-go EIPs are billed based on data transfer or bandwidth usage.
Overview
- You can release a pay-as-you-go EIP at any time. After an EIP is released, the bill of the current hour or day is generated the next hour or day, and then fees are deducted from your account.
- When you associate an EIP with an Elastic Compute Service (ECS) instance, you are not charged a configuration fee. However, you are charged a configuration fee when you associate an EIP with a NAT gateway, a Server Load Balancer (SLB) instance, a secondary Elastic Network Interface (ENI) instance, or a high-availability virtual IP address (HAVIP).

The maximum bandwidth indicates the upper limit of the bandwidth and is for reference only. The peak bandwidth is not guaranteed. In scenarios where demands exceed resources, the peak bandwidth may be limited. | The maximum bandwidth equals the peak bandwidth. In scenarios where demands exceed resources, the peak bandwidth can reach the maximum bandwidth. |
The sum of the peak bandwidth of all pay-by-data-transfer EIPs in each region cannot exceed 5 Gbit/s. If your business requires a guaranteed bandwidth or larger bandwidth, you can purchase pay-by-bandwidth EIPs. | The sum of the maximum bandwidth of all pay-by-bandwidth EIPs in each region cannot exceed 50 Gbit/s. You can contact your product manager to increase the quota. |
Pay-by-data-transfer
Total fee = Configuration fee + Data transfer fee. The billing cycle is one hour. Fees are calculated and bills generated on an hourly basis. If you use an EIP for less than one hour, the usage duration is rounded up to one hour.
- Configuration fee = Instance unit price (USD/hour) × Usage duration (hours)
Usage duration refers to the time period from when an EIP is created to when it is released.
- Data transfer fee = Unit price of data transfer (USD/GB) × Amount of data transfer
(GB)
Data transfer refers to the cumulative outbound traffic of an EIP. Inbound traffic is not charged. Outbound traffic refers to the traffic that is transmitted from the data center of Alibaba Cloud to the Internet.

Pay-by-bandwidth
Total fee = Configuration fee + Bandwidth fee. The configuration fee and bandwidth usage fee are billed on an hourly basis. If you use the service for less than one hour, the usage duration is rounded up to one hour. The billing cycle is one day. Fees are calculated and bills are generated on a daily basis.
- Configuration fee = Instance unit price (USD/day) × [Usage duration (hours)/24] (days)
Usage duration refers to the time period from when an EIP is created to when it is released.
- Bandwidth usage fee
- 1 Mbit/s ≤ Maximum bandwidth ≤ 5 Mbit/s: Bandwidth usage fee = Bandwidth unit price (USD/day for every Mbit/s) × [Usage duration (hours)/24] (days) × Maximum bandwidth
- Maximum bandwidth > 5 Mbit/s: Bandwidth usage fee = Unit price of bandwidth from 1
to 5 Mbit/s (USD/day for every Mbit/s) × [Usage duration (hours)/24] (days) × 5 +
Unit price of bandwidth higher than 5 Mbit/s (USD/day for every Mbit/s) × [Usage duration
(hours)/24] (days) × (n-5).
In the preceding formula, n represents the maximum bandwidth value.
The bandwidth usage fee is calculated based on a tiered pricing model with 5 Mbit/s as the standard bandwidth value.
You can modify the maximum bandwidth at any time. If you increase or decrease the maximum bandwidth, the bandwidth usage fee is calculated based on the highest value on that day.

Example
- At 17:00:00 (UTC+8), you change the maximum bandwidth from 10 Mbit/s to 20 Mbit/s.
- At 23:00:00 (UTC+8), you change the maximum bandwidth from 20 Mbit/s to 15 Mbit/s.

The following table describes how fees are calculated based on the billing method that you select.
Billing method | Configuration fee | Data transfer fee or bandwidth usage fee | Total fee |
---|---|---|---|
Pay-by-data-transfer EIPs | The configuration fee is:
|
The data transfer fee is:
|
Total fee = Configuration fee (USD) + Data transfer fee (USD) = USD 0.045 + USD 7.38 = USD 7.425. |
Pay-by-bandwidth EIPs | The configuration fee is:
|
The bandwidth usage fee is:
|
Total fee = Configuration fee + Bandwidth usage fee = USD 0.04625 + USD 5.125 = USD 5.17125. |
