 Contracted Cost represents the cost calculated by multiplying [*contracted unit price*](#glossary:contracted-unit-price) and the corresponding [Pricing Quantity](#pricingquantity). Contracted Cost is denominated in the [Billing Currency](#billingcurrency) and is commonly used for calculating savings based on negotiation activities, by comparing it with [List Cost](#listcost). If [*negotiated discounts*](#glossary:negotiated-discount) are not applicable, the Contracted Cost defaults to the List Cost.
