Bill estimates
Bill estimates allows you to estimate pre-tax costs of your usage and commitments across your consolidated bill family. This type of estimate automatically includes your last month's consolidated billing usage. It also includes your existing purchase commitments like Savings Plans and Reserved Instances. You can model new usage changes as well as add new commitments and modify your existing commitments.
To generate a bill estimate you must create a bill scenario. Bill scenario allows you to model commitments in addition to usage. After you complete modeling usage and commitments in a scenario, you can run a bill estimate.
