Starting today, AWS Billing Conductor (ABC) customers can analyze the margins (realized savings) for each AWS service their accounts are using. ABC calculates margin by evaluating the difference between the proforma “charged amount” calculated by the service, and the invoiced costs for accounts in billing groups. Margin values can be positive or negative. For example, customers purchasing Compute Savings Plans within their management account can evaluate the savings rate of those purchases for each covered service relative to their AWS invoiced amount. This analysis will simplify customers’ chargeback method and drive deeper understanding of where they are achieving savings.
