Conventional services as well as web services are explored and discovered by descriptions of their properties. Such properties are either functional or non-functional. Amongst the non-functional properties is the price for service consumption. Evaluating the price of a service is difficult due to a huge variety of existing pricing models and conditions. But still, it is important to a service consumer to evaluate arising costs, esp. in scenarios of long-term usage and if combining several services. In theory and practice so far there exists no method that sufficiently guides the decision of selecting specific services regarding the non-functional property price. This paper strives to promote research-in-progress for such a method, which is based on the TCO concept and on insights from capital budgeting in investment theory. The method is indented to support service consumers in selecting a specific service, in comparing several functionally similar services, and finally in evaluating complete service orchestrations.
