A company planning a migration to AWS needs a monthly estimated total cost for future Amazon EC2 instances and related storage. Which tool should they use?

The AWS Pricing Calculator provides estimated costs for AWS services, including Amazon EC2 instances and storage, based on user-defined configurations. This allows companies to forecast expenses before migrating or deploying resources. AWS Compute Optimizer recommends optimal AWS resources for workloads to reduce costs and improve performance, but it doesn't provide a total estimated cost for new infrastructure. AWS Trusted Advisor offers recommendations to optimize costs, security, and performance of existing AWS resources, not future ones. AWS Application Migration Service (AWS MGN) helps automate the rehosting of applications to AWS, but it's a migration tool, not a cost estimation tool.
