List Cost Analysis

CloudCheckr’s List Cost algorithm performs many customizable changes to your cost data, from simple ones such as charging AWS’ actual list price for a service that might have received bulk pricing, to complex ones such as “unsharing” Reserved Instances costs so that when you invoice your payees they will not receive the RI discounts that should only be enjoyed by RI owner.

This report shows you each billing line from your DBR that was modified when your List Cost was created. This will help you validate any changes you see in your List Cost, and help you explain any changes to your customers in the event they have any questions.

 

Example 1:

In this example, you are seeing Amortization charges added to specific EC2 instance usages. This means that the Payer has used CloudCheckr’s EC2 RI Amortization functionality to add in the cost of the instance’s upfront fees to the daily usage, therefore giving an accurate indication of true cost and accurately billing the payee for the cost of the instance

Example 2:

In this example, you can see the effect of a Custom Charge that was created for List Cost. A 100% discount was given—the effect is that the original charge of $2.59 was reversed out to $0.00.

Example 3:

In this example, RI Unsharing has occurred. An account’s EC2 instance took advantage of another account’s RI for a total discounted cost of $0.86. Under List Cost, this was reversed and the proper On-Demand rate was applied, resulting in a total cost of $2.17.

TIP:

For any rows showing “Unknown” for Service (as displayed above), you will need to reload the month(s) in question before the service will appear. Also, the Description field indicates that this is an EC2 billing item, which is another helpful data point.
