Billable items
The following table describes the billable items of MNS.
Billable item | Description | Billing method | Billing cycle |
API requests to topics | You are charged based on the number of API requests initiated by clients to topics. | Pay-as-you-go | Fees for MNS are calculated on an hourly basis and bills are issued every 24 hours. The fees are automatically deducted from your account balance. Each day, Alibaba Cloud calculates your resource usage of the previous day, issues a bill, and deducts the fees from your Alibaba Cloud account balance. |
API requests to queues | You are charged based on the number of API requests initiated by clients to queues. | ||
Message size | The message body in each API request has a size limit of 64 KB. If you want to send a message whose size is larger than 64 KB, you must call multiple API requests to send the message. For example, if you want to publish or subscribe to a message of 256 KB, four API requests are called to publish or subscribe to the message. The number of API requests is calculated by using the following formula: 256/64 = 4. | ||

Queues are billed on a daily basis and the bills are billed to the Alibaba Cloud account.
If you no longer need a queue, delete the queue at the earliest opportunity to prevent unnecessary costs.
Before June 8, 2019, Alibaba Cloud charged users for no more than 10 queues in each region for all queues created in MNS. This provides users with sufficient time to familiarize themselves with MNS and optimize usage. Starting from June 8, 2019, Alibaba Cloud charges users for all queues created in MNS. We recommend that you delete the queues that you no longer need to prevent unnecessary costs.

Date | Number of queues created | Number of queues billed | Unit price (USD per queue-day) | Fee (USD) |

The number of API requests is calculated on an hourly basis, measured in millions, and accurate to two decimal places.
The message body in each API request has a size limit of 64 KB. If you want to send a message whose size is larger than 64 KB, you must call multiple API requests to send the message. For example, if you want to publish or subscribe to a message of 256 KB, four API requests are called to publish or subscribe to the message. The number of API requests is calculated by using the following formula: 256/64 = 4.
After you delete a topic, stop sending API requests to the topic at the earliest opportunity. Otherwise, you are still charged for the API requests that are sent to the topic.
You are charged for API requests to topics over the Internet and the internal network.
Billing example
For example, you create topics in the China (Hangzhou) region. The unit price for API requests to the topics is USD 0.32 per million requests. You are provided with a free quota of 20 million requests and charged for the excess requests. In this example, 22 million requests are sent to the topics, which exceeds the free quota by 2 million. In this case, the fee for API requests to topics is 2 x 0.32 = 0.64 USD.
