The AWS Pricing Calculator now offers a redesigned user interface that allows you to generate price estimates for Amazon Elastic Compute Cloud (Amazon EC2) instances in the shared tenancy model, the dedicated tenancy model, and Amazon EC2 dedicated hosts. The calculator makes it easier for you to switch among the three tenancy options with a single click, by providing a common user interface to enter input parameters for cost estimation. The calculator will also pre-populate costs across the available pricing models (e.g. Savings Plans, Reserved Instances), removing the need to view costs for each price model separately and allowing you to do quick cost comparison.
