An RPA must approach the rate calculation process carefully, so as to gain a good understanding of the business issues and monetary risks inherent in providing goods and services for a fee. This is especially important if the RPA will serve federally funded activities where most agreements are for the reimbursement of costs only, and charges are subject to audit and disallowance by both federal and state auditors.
In building rates for goods or services, departments should follow generally acceptable accounting principles and reasonable cost accounting practices.
