This document outlines the components of cost in a cost sheet, including prime cost, factory/works cost, office and administration cost, and total cost. It defines prime cost as direct materials, direct wages, and direct expenses. Office and administration cost includes expenses related to operating and maintaining the business. Total cost is the cost of production plus selling and distribution expenses. The document also compares cost accounts to cost sheets, noting that cost sheets are not based on double entry accounting and are useful for making comparisons and ascertaining per unit costs to help with cost control and guidance.
