There is no additional charge for Amazon Elastic Beanstalk. You pay for Amazon Web Services resources (e.g. EC2 instances or S3 buckets) you create to store and run your application. You only pay for what you use, as you use it; there are no minimum fees and no upfront commitments.
The costs of running a web site using Elastic Beanstalk can vary based on several factors such as the number of Amazon EC2 instances needed to handle your web site traffic, the bandwidth consumed by your application, and which database or storage options your application uses. The principal costs for a web application will typically be for the Amazon EC2 instance(s) and for the Elastic Load Balancing that distributes traffic between the instances running your application.
