How do I see last month's (RDS) cost per instance in AWS?

Question

For some reason, I am finding it hard to understand where to access this information.

In last month's bill, I see that my RDS has 14000 hours, which is weird since a month only has 730 hours, and I only have 1 RDS.

So my question, what is the most straight forward way to list the cost per RDS instance of a specific month in AWS?

A step by step guide would be extremely helpful, as AWS billing and cost reports can be a jungle to navigate.

Thanks!

Answer 1

You can use the Cost Explorer.

1. Go to Cost Management console.
2. Select Cost Explorer in the menu.
3. Set filter: Service=Relational Database Service

You can then group by usage type or instance type as necessary.
