Chapter 7. Relevant Cost concept for decision making. Calculate the five year costs and identify the least cost option Step 1: identify the relevant costs. Step 2: determine if the cost is 1 time or recurs for each of the 5 years. If it is one time, multiply x 1, if it is a 5 year cost then multiply by 5 Step 3: Add up all of the costs for each model and determine which machine has the LOWEST 5 year cost to the company. You are planning to purchase a range and have to make a choice among the following three models of the same type of equipment: Model IModel 2 Model 3 Cash cost Estimate life Trade-in value at end of life Cash from sale of old machine Installation of new machine Initial training cost in Year I Annual maintenance contract Annual cost of supplies Annual wage costs of employees S 5,000 5,500 5,300 years 5 years 5 1,000 1,200 S 200 200 S 80 120 S 350 300 S 275 300 S 175225 32,000 $32,000 800 200 100 325 250 200 $32,000 CHAPTER 7 COST MANAGEMENT Using the concept of relevant costs over the five-year period, which model would be the best investment?
