4. 4 Some typical short-term problems in organisations Should a service or product be withdrawn from the market or a segment of an organisation be closed? Is the most profitable sales plan being followed or will alternatives lead to higher profits. Should a component be made (or service provided) by the company or should it be bought in from another supplier? Is the optimum sales and production plan being followed, given a shortage of a key resource such as labour skills, raw materials or machine capacity? © 2008 John Wiley & Sons Ltd. www.wileyeurope.com/college/bowhill

5. 5 Richmond PLC Budgeted Profit and Loss Account for 20X0 £ Revenue 1,581,500 Total costs 1,487,750 Profit 93,750 The total costs include fixed costs of £247,250. Calculation of the fixed overhead per unit i) Budgeted fixed overheads are £247,250 ii) Budgeted output is 21,500 units sold (6,500 units of product X, 8,000 units of product Y, 7,000 units of product Z). iii) To calculate the fixed cost per unit, the fixed overheads of £247,500 are divided by 21,500 units. This gives a fixed cost of £11.50 per unit. © 2008 John Wiley & Sons Ltd. www.wileyeurope.com/college/bowhill

16. 16 Cost terms Incremental costs are those that change as a result of a decision and include identifiable fixed costs. Relevant and irrelevant costs. In decision making, relevant costs are the costs that change because of a decision. Irrelevant costs are general overheads and other costs that do not change. Sunk costs are those that have already been spent or the commitment has been made to spend them. Sunk costs are not relevant to a decision. Opportunity cost is a cost that measures the opportunity that is lost or sacrificed when an opportunity is foregone. © 2008 John Wiley & Sons Ltd. www.wileyeurope.com/college/bowhill
