With IT budgets being carefully scrutinized, IT chargeback is an alluring notion. But many IT organizations struggle with how to implement an IT chargeback system that is fair and practical.
The idea is to charge business units for the IT resources they use, shifting the burden of IT budget justification to the consumers of the resources and making IT less of a cost center. Expenditures are driven by the business units, who suddenly become much more cost-conscious, and decisions are based on a truer cost of obtaining new business. Therein lies the real value of an IT chargeback system - allowing people to make better business decisions by including IT costs in the mix.
For many data centers undergoing server consolidation, IT chargeback gets more complicated than the one application per server policy. But without consolidation, servers are often underutilized, wasting significant resources.

To enable correct charging, it is necessary to have adequate measurements of resource consumption. The kind of measurement to use depends on the type of resource in focus. CPU utilization is most likely the best measurement for an application server, whereas chargeback for a file server probably should be based on the relative amount of disk space occupied. If you include a database server, you might need a combination of the two. A cost model and charging policy needs to be designed individually for each organization.
