Isn’t that exactly what the person you replied to said? You’re showing what you’ve been charged for previously. That part works, at a certain level of detail.

If you set up your infrastructure with CloudFormation (as you should), you can get a cost estimation of how much your solution would cost. https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGui...
A lot of people use Terraform (my shop does) and I've found a good terraform setup way better than CF templates. You can do tags in Terraform too. You should be forced to use their already bad tooling just to get correct cost estimates.
