2.2. Relevant Costs for Replacement Analysis

So, this is all about your defender that is the current equipment. Now let us discuss about the challenger, that is a proposed equipment. The challenger's annual operating and maintenance cost is 90,000. So, you can see that it is lesser than your old equipment, so lesser than your defender. So, the defender operating and maintenance cost is 1,35,000 but your challenger operating cost is 90,000, so it is lesser.

In a replacement analysis, you need to compare your existing equipment (defender) with the proposed new equipment (challenger). In this case, the challenger has a lower annual operating and maintenance cost compared to the defender, making it seem more favorable at first glance. Specifically, the defender costs 135,000 in maintenance while the challenger only costs 90,000. This cost difference is significant when considering which equipment to keep.

Imagine a family deciding between keeping an old car that costs them $1,350 a year in maintenance or switching to a newer car that only costs$900 a year. The family will likely choose to buy the new car because it saves them money each year.

For the replacement analysis, as I told you your initial estimates should be ignored or neglected, they are not relevant. Your initial purchase price 35,00,000 it should not be considered in the replacement analysis. And similarly your initial estimate of salvage value 7,00,000 is should not be considered.

When conducting a replacement analysis, certain costs that are historical or incurred in the past are irrelevant. This includes the initial purchase price of the current equipment and its estimated salvage value. The decision should be based on future cash flows rather than past expenditures since these do not affect the cost of maintaining or replacing the equipment going forward.

Think of it like choosing between two smartphones. If you initially paid $1,000 for your old phone, that cost doesn’t affect your choice of whether to keep it or switch to a new phone priced at$800. What matters are the future costs, like how much each phone will cost to run or maintain.

Also, as I told you your sunk cost, so what is the sunk cost? So, it is a estimated book value of the machine, this is the estimated book value of the machine using depreciation accounting method it is currently 3,80,000. But your current trading value is only 22,50,000 this difference cannot be recovered, this difference is called as the sunk cost.

Sunk costs are expenses that have already been incurred and cannot be recovered. In this context, the current estimated book value of the old equipment represents the amount spent that is now considered a sunk cost, as it won't influence future decisions about whether or not to keep or replace the equipment. Instead, the focus should be on current valuation and future costs.

Consider someone who bought concert tickets for $100. If they can’t attend the concert, that$100 is a sunk cost. Whether or not they should try to get new tickets to a different concert shouldn’t depend on the money they've already spent on the first tickets.

From the above calculations you confine that the equivalent uniform annual cost of the defender is 630270. So, it is more than that of the equivalent annual cost of challenger which is 6,18,890. Hence it is advisable to replace your defender with a challenger.

After performing all necessary calculations, you compare the equivalent annual costs of both options. In this case, the defender's cost is higher than the challenger's. Thus, the rational decision is to replace the defender with the challenger, as this approach minimizes costs.

Just like a family reviewing their monthly expenses and realizing that switching to a more economical internet provider would save them more money, here you're analyzing the costs of different machines to find the most cost-effective option.
