**Introduction:** AWS Lambda is a versatile serverless computing service that allows you to run code without provisioning or managing servers. However, understanding the cost implications of your Lambda functions is crucial for efficient resource allocation. To help you with this, we’ve created the Lambda Cost Calculator for AWS, which simplifies the process of estimating your monthly Lambda costs.

**Formula:** To calculate the monthly cost of your Lambda function, we use the following formula:

Monthly Cost = (Lambda Executions) * (Lambda Duration / 100) * $0.00001667

Where:

- Lambda Executions: The number of times your Lambda function is executed.
- Lambda Duration: The execution duration of your Lambda function in milliseconds.
- $0.00001667: The cost per GB-second for Lambda functions.

**How to Use:**

- Enter the number of Lambda executions in the “Lambda Executions” field.
- Input the Lambda execution duration in milliseconds in the “Lambda Duration” field.
- Click the “Calculate” button to estimate your monthly Lambda cost.

**Example:** Suppose you have 100,000 Lambda executions with an average duration of 200 milliseconds.

Monthly Cost = (100,000) * (200 / 100) * $0.00001667 = $33.34

**FAQs:**

**Q:**How is the Lambda duration calculated?**A:**The Lambda duration is the time it takes for your function to execute, measured in milliseconds.**Q:**Is this calculator accurate for all AWS regions?**A:**Yes, it provides an estimate based on the standard AWS Lambda pricing.**Q:**What if I have variable execution durations?**A:**This calculator assumes an average duration; actual costs may vary.**Q:**Are there any hidden fees not accounted for?**A:**No, this calculator uses the publicly available AWS Lambda pricing.**Q:**Can I use this for Lambda@Edge?**A:**Yes, you can estimate costs for Lambda@Edge functions as well.

**Conclusion:** Our Lambda Cost Calculator for AWS is a valuable tool to quickly estimate your monthly Lambda expenses. By inputting the number of executions and average execution duration, you can gain insights into your AWS Lambda costs, enabling better budgeting and resource management for your serverless applications.
