- In a factory where there are three shifts: The machine overhead cost is found to be £8.20 / hr, the labour overhead cost is found to be £30.20/hr, and the premises overhead cost is found to be £3.50/hr. Using the principle of overhead costing: If a single component takes 23 minutes to manufacture on the milling machine. What is the cost / part? You should include machine costs, labour costs and premises costs in your answer, but you can neglect material and energy costs.
