Understanding Relevant Costs
Unlock Audio Lesson
Today, we will be discussing relevant costs in equipment replacement. What do you think plays a role in determining these costs?
I think we should consider the operating costs and perhaps the salvage value?
Exactly! We focus on factors like current operating costs and future salvage values, but what should we ignore?
We shouldn't consider the initial purchase price or the previous salvage values, right?
Correct! Sunk costs and past estimates have no impact on our decision now. Remember the acronym R-E-S: Relevant, Excluded, Sunk.
That's a handy way to remember!
Great! Let's recap that relevant costs are those that impact future cash flows while sunk costs do not affect our future decisions.
Calculating Equivalent Annual Costs
Unlock Audio Lesson
Next, let's dive into the calculation of the Equivalent Annual Cost or EAC. Why do you think it’s important to convert costs to an annual basis?
It helps in comparing costs of different machines on a similar time scale.
Exactly! Now, when calculating EAC, what formula might we use?
We can use the Uniform Series Capital Recovery Factor for the initial cost!
Right! And for salvage values? What can we use?
The Uniform Series Sinking Fund Factor?
Yes! Remember it with the acronym SINK, for Sinking Fund Factor. Overall, we find EAC by combining these calculations.
Final Decision Making
Unlock Audio Lesson
Finally, once we have the EAC for both the defender and challenger, how do we proceed?
We compare the two EACs to determine which one is cheaper to operate over time!
Correct! So, let’s say the defender's EAC is 6,30,270 and the challenger's is 6,18,890. Which machine should we keep?
We should replace the defender since the challenger has a lower EAC!
Excellent! Always replace the machine with the higher EAC when a lower one is available.
This analysis makes decision-making much clearer!
Introduction & Overview

Quick Overview
Standard
It covers the financial assessment of retaining an existing machine (defender) versus replacing it with a new machine (challenger). The analysis emphasizes the consideration of various costs such as annual operating costs, salvage values, and how to calculate their equivalent annual costs (EAC) using specific formulas.
Detailed
Salvage Value Conversion to EAC
This section focuses on the analysis of replacing current equipment (defender) with new equipment (challenger). The challenger incurs lower annual operating costs of 90,000 compared to the defender's costs of 1,35,000, and offers a salvage value of 12,00,000 after five years. The significance lies in determining the financial implications of keeping the defender or replacing it with the challenger.
Key Points Covered:
- Operating Costs: Analysis shows that the defender's operating cost is higher than that of the challenger, highlighting the need for a detailed financial comparison.
- Relevant Cost Factors: Initial costs, sunk costs, salvage value, and remaining life estimates for the defender are discussed with emphasis on omitting irrelevant historical data during analysis.
- Calculation of Equivalent Annual Costs (EAC): Detailed steps illustrate the conversion of total costs into equivalent annual costs using time value methods to make an informed replacement decision.
- Final Comparison: EAC calculations for both machines highlight that the challenger is financially more viable, guiding the decision to replace the defender.
This analysis encapsulates critical decision-making in machinery procurement and costs in engineering finance.

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.
Detailed Explanation
This chunk introduces the comparison between two pieces of equipment: the defender and the challenger. The defender represents the current equipment with an operating and maintenance cost of 135,000, while the challenger, the proposed new equipment, has a lower annual operating cost of 90,000. This cost difference is a crucial factor when deciding whether to replace the old equipment.
Examples & Analogies
Imagine you have an old car that costs you $1,350 a year for maintenance. If you find a newer model that only costs $900 per year to keep running, the significant savings might make you consider replacing your old car.
Salvage Value Estimation

And the salvage value for the challenger is 12,00,000 after 5 years. So, the life of the challenger we are considering is for 5 years, investment cost is 10% per year.
Detailed Explanation
Here, the salvage value of the proposed challenger equipment after 5 years is estimated to be 1,200,000. This is important for evaluating the overall cost-effectiveness of the challenger, as this value can be subtracted from the total costs incurred over its lifespan. Additionally, an investment cost of 10% per year can affect the calculation of future worth or net present value.
Examples & Analogies
Think of buying a smartphone. If you expect to sell it for $1200 after five years, knowing this future value helps you determine how much you're willing to spend upfront by comparing with ongoing expenses.
Replacement Analysis Relevance

And similarly your initial estimate of salvage value 7,00,000 should not be considered. And the estimated current book value using your depreciation accounting method 23,80,000 is also not relevant in the analysis.
Detailed Explanation
In the context of replacement analysis, outdated or initial estimates such as salvage value and the current book value based on depreciation do not influence the decision-making process. This underscores the principle that replacement decisions should focus on relevant current values rather than historical costs.
Examples & Analogies
Imagine planning a home renovation. If you focus on how much your current furniture is worth rather than how well it will serve your needs moving forward, you might miss out on better options. This chunk emphasizes that similar old estimates should not cloud the judgement for the new equipment.
Ignoring Sunk Costs

So, what is the sunk cost? So, it is an 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.
Detailed Explanation
Sunk costs refer to expenses that are incurred and cannot be recovered, such as the depreciation of the defender equipment. Here, the estimated book value and market value illustrate how past investment should not influence current decisions. Ignoring these sunk costs can help make clearer financial choices.
Examples & Analogies
Imagine you've spent $300 on a concert ticket but have fallen ill. Choosing to go based on the money spent, rather than the enjoyment you’d receive, is a sunk cost fallacy. Knowing when to let go of non-recoverable costs aids in better decisions.
Equivalent Annual Cost Calculation

Now for the existing equipment that is defender what are all relevant in the replacement analysis or what are all to be considered in the replacement analysis, let us see that. Current market value is 22,50,000, this is your initial cost of your the first cost of your defender, this is what we are going to consider.
Detailed Explanation
In assessing the defender for replacement analysis, its current market value (2,250,000) is identified as relevant. The analysis requires this current trading value to evaluate if the defender should continue to be used or if it should be replaced by the challenger based on cost-effectiveness over time.
Examples & Analogies
Consider evaluating your house for sale—what you initially paid for it is less relevant than what it can currently fetch in the market. Making renovations based on current value can ensure you get the best return on your investment.

So, based upon this you are supposed to calculate the equivalent annual cost of the defender. We are going to estimate the equivalent annual cost of the defender. So, for that you need to draw the cash flow diagram.
Detailed Explanation
To derive the equivalent annual cost (EAC) of the defender, a cash flow diagram is necessary. This diagram helps visualize all costs and expected cash inflows over time, simplifying the process of calculating the EAC based on these values, effectively detailing how much the current equipment costs on an annual basis.
Examples & Analogies
Think of budgeting for a monthly subscription: charting out what you earn and what you spend each month can give you a clearer picture of your financial health. Similarly, the cash flow diagram provides a roadmap for understanding the defender's costs over time.
Final EAC Calculation

So, this is the equivalent annual cost of your initial cost of defender, so we have estimated it. Already the operating and the maintenance cost already annualized cost, so you need not convert them.
Detailed Explanation
In concluding the calculation for the EAC of the defender, the previously calculated values combined with the annual operating cost showcase the total annual costs involved in maintaining the defender. By summing these, one deduces the annual financial liability of retaining the equipment.
Examples & Analogies
If you have a monthly car expense tally (fuel, maintenance, insurance), calculating the total cost helps you decide if the car is worth keeping versus selling it for something more efficient.

So, in this case, the challenger cost liability is minimum, so it is preferable to replace a defender with the challenger.
Detailed Explanation
Ultimately, the comparison between the EAC of the defender and that of the challenger reveals that the challenger holds a lower annual cost liability. Thus, this financial analysis guides the decision to replace the defender, as the challenger is financially advantageous.
Examples & Analogies
Just like comparing two pairs of shoes, where one pair is cheaper and more comfortable—identifying which one costs less over time leads to a better purchase decision. Similarly, it’s crucial to choose the machine that offers better financial longevity.
