Estimating the Cost of Your AWS CloudFormation Stack
There is no additional charge for AWS CloudFormation. You pay for AWS resources (e.g. Amazon EC2 instances, Elastic Load Balancing load balancers and so on) created using AWS CloudFormation as if you created them by hand.
We recommend that you use the Amazon Web Services Simple Monthly Calculator at http://calculator.s3.amazonaws.com/calc5.html to estimate the cost of your stacks beforehand. You can also estimate the cost of your stacks while creating or updating a stack from the AWS CloudFormation console.
To estimate the cost of your stack
On the Review page of the Create Stack or Update Stack dialog, click the Cost link.
This link opens the AWS Simple Monthly Calculator in a new browser page (or tab, depending on how your browser is set up).
Note
Because you launched the calculator from the AWS CloudFormation console, it is pre-populated with your template configuration and parameter values. There are many additional configurable values that can provide you with a better estimate if you have an idea of how much data transfer you expect to your Amazon EC2 instance. For more information about what factors contribute to the total cost of your AWS resources, see the AWS Pricing Overview whitepaper, which can also be accessed by clicking the help link at the top of the calculator page.
Click the Estimate of your Monthly Bill tab for a monthly estimate of running your stack, along with a categorized display of what factors contributed to the estimate.
