Am I using the AWS cost calculator correctly?

I need 4 instances, 1 m4.large, 2 m4.xlarge, and 1 m4.4xlarge, all with Windows and Std SQL Server. Is the price actually ~$4700 per month to keep the 4 instances up and running 100% of the time? This excludes data transfer costs and elastic IP address costs. This is the calculator in question.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

As configured, that would be correct.  If you are considering spending that amount monthly, it might be in your interest to re-evaluate your database resource requirements and consider using Reserved Instances or Amazon RDS for SQL Server.
