Azure Functions offer serverless computing capabilities, allowing you to run code without the need to manage infrastructure. While this provides scalability and cost-efficiency, it’s essential to understand the associated costs. The Azure Function Cost Calculator helps you estimate your expenses by considering the number of function executions, average execution time, and memory usage.
Formula
To calculate the cost of using Azure Functions, we use the following formula:
Cost = (Cost per Execution * Number of Function Executions) + (Cost per GB-second * (Memory Used in GBs) * (Execution Time in seconds))
Where:
- Cost per Execution is the cost of each function execution.
- Number of Function Executions is the total number of times your function is executed.
- Cost per GB-second is the cost of memory usage per second.
- Memory Used in GBs is the amount of memory your function uses in gigabytes.
- Execution Time in seconds is the average execution time of your function in seconds.
How to Use
- Fill in the Number of Function Executions, Average Execution Time, and Memory Used in the calculator above.
- Click the “Calculate” button.
- The estimated cost of using Azure Functions will be displayed below the form.
Example
Let’s consider an example: You have 10,000 function executions with an average execution time of 100 milliseconds and a memory usage of 128 MB.
- Number of Function Executions: 10,000
- Average Execution Time: 100 ms (0.1 seconds)
- Memory Used: 128 MB
After entering these values and clicking “Calculate,” the estimated cost will be displayed.
