Cost Breakdown
How to Estimate Your AWS Serverless Costs
This free calculator helps you estimate monthly AWS costs for a typical serverless architecture. Enter your expected usage for each service and toggle the AWS Free Tier to see how it affects your bill during the first 12 months.
Lambda pricing is based on the number of requests and GB-seconds of compute time. A GB-second is calculated as (memory in GB) x (duration in seconds). The free tier includes 1 million requests and 400,000 GB-seconds per month.
API Gateway charges $3.50 per million REST API calls. S3 charges $0.023 per GB of storage plus per-request fees. CloudFront charges $0.085/GB for the first 10 TB of data transfer plus $0.01 per 10,000 HTTPS requests.
DynamoDB on-demand pricing is $1.25 per million write request units and $0.25 per million read request units, plus $0.25/GB for storage. SQS costs $0.40 per million requests after the free tier, and SNS costs $0.50 per million publishes after the first million.
