Azure Functions pricing

Azure Functions consumption plan is billed based on per-second resource consumption and executions. Consumption plan pricing includes a monthly free grant of 1 million requests and 400,000 GB-s of resource consumption per month per subscription in pricing across all function apps in that subscription. Customers can also run Functions within their App Service plan at regular App Service plan rates.

*The following prices are tax-inclusive.

*Monthly price estimation is based on a usage of 31 days per month.
Execution Time* ¥ 0.000113/GB-s 400,000 GB-s
Total Executions* ¥ 1.30 per million executions行 1 million executions
* Free grants apply to paid, consumption subscriptions only.

Note - A storage account is created by default with each Functions app. The storage account is not included in the free grant. Standard storage rates and networking rates charged separately as applicable.

Pricing details


Functions are billed based on total number of requested executions each month for all functions. Executions are counted each time a function is executed in response to an event, triggered by a binding. The first million executions are included free each month.

Resource consumption

Functions are billed based on observed resource consumption measured in gigabyte seconds (GB-s). Observed resource consumption is calculated by multiplying average memory size in gigabytes by the time in milliseconds it takes to execute the function. Memory used by a function is measured by rounding up to the nearest 128 MB, up to the maximum memory size of 1,536 MB, with execution time calculated by rounding up to the nearest 1 ms. The minimum execution time and memory for a single function execution is 100 ms and 128 mb respectively. Functions pricing includes a monthly free grant of 400,000 GB-s.

Pricing example

A function with observed memory consumption of 512 MB executes 3,000,000 times during the month and has an execution duration of one second. Monthly billing would be calculated as follows:
