With AWS Lambda, you pay only for what you use. You are charged based on the number of requests for your functions and the duration, the time it takes for your code to execute.
Lambda pricing details
Lambda counts a request each time it starts executing in response to an event notification or invoke call, including test invokes from the console. You are charged for the total number of requests across all your functions.
Duration is calculated from the time your code begins executing until it returns or otherwise terminates, rounded up to the nearest 100ms. The price depends on the amount of memory you allocate to your function.
The Lambda free tier includes 1M free requests per month and 400,000 GB-seconds of compute time per month.
The Lambda free tier includes 1M free requests per month and 400,000 GB-seconds of compute time per month. The memory size you choose for your Lambda functions determines how long they can run in the free tier. The Lambda free tier does not automatically expire at the end of your 12 month AWS Free Tier term, but is available to both existing and new AWS customers indefinitely.
The table below shows the free tier seconds and the approximate price per 100ms associated for different memory sizes.
|Memory (MB)||Free tier seconds per month||Price per 100ms ($)|
You may incur additional charges if your Lambda function utilizes other AWS services or transfers data. For example, if your Lambda function reads and writes data to or from Amazon S3, you will be billed for the read/write requests and the data stored in Amazon S3.

Lambda pricing examples
Lambda@Edge pricing details
There is no free tier for Lambda@Edge at this time.
You are charged for the total number of requests across all your functions. Lambda@Edge counts a request each time it starts executing in response to a CloudFront event globally.
Request pricing is $0.60 per 1 million requests ($0.0000006 per request).
Duration is calculated from the time your code begins executing until it returns or otherwise terminates. You are charged $0.00005001 for every GB-second used. For instance, if you allocate 128MB of memory available per execution with your Lambda@Edge function, then your duration charge will be $0.00000625125 for every 128MB-second used. Note that Lambda@Edge functions are metered at a granularity of 50ms.
