Now, moving on to equivalent annual cost – can anyone explain why we calculate this?
It helps us figure out the annual cost of each piece of equipment over its lifespan.
Right! We do this to compare options effectively. For the defender with a present value of 22,50,000, what would be the next step?
We would use the uniform series capital recovery factor to find EAC.
Good! This leads us to an EAC of approximately 5,93,550 for the defender.

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 two types of equipment under consideration: the 'defender' (current equipment) and the 'challenger' (the proposed new equipment). The annual operating and maintenance costs of both pieces of equipment are compared, with the challenger being less expensive at 90,000 compared to 1,35,000 for the defender. This cost difference is crucial as it forms the basis for the decision-making process in the replacement analysis.
Examples & Analogies
Imagine you have an old car (the defender) that costs you $1,350 a year for maintenance, while a new car (the challenger) only costs you $900. Considering costs alone, the new car is more economical and could save you money in the long run.

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, we learn about the salvage value, which refers to the estimated resale value of the challenger at the end of its useful life, given as 12,00,000 after 5 years. This segment also establishes the analysis period, indicating that we're considering a 5-year life cycle for the challenger. This is key in calculating the equipment's equivalent annual cost as it affects both the depreciation and the expected cash inflows from the salvage value.
Examples & Analogies
Think of it like buying a smartphone for $1,200 that you plan to sell for $600 after 5 years. The salvage value is what you expect to get back after using it, which helps you understand how much the phone will really cost you over time.

Now we are supposed to compare the challenger and the defender, find out whether the defender should be retained or replaced with the challenger using time value or annual worth method.
Detailed Explanation
This part emphasizes the need for a thorough replacement analysis to determine if the existing defender should be replaced with the challenger. It mentions using the time value of money or the annual worth method for this analysis, indicating that future costs and savings will be adjusted to reflect their present value. This is crucial to making an informed economic choice.
Examples & Analogies
Imagine upgrading your home appliances. You assess if the new refrigerator with lower electricity bills is worth the investment compared to keeping the old one. You would evaluate the long-term savings and weigh them against the purchase price based on their present value.
Sunk Cost Considerations

Chapter Content
All old estimates should be neglected in the replacement analysis. And also, as I told you your sunk cost... this cost which is spent and it is lost, it cannot be recovered.
Detailed Explanation
This chunk discusses the concept of sunk costs, which are costs that have already been incurred and cannot be recovered regardless of future actions. It explains that for a meaningful replacement analysis, one must disregard these old costs because they do not impact future financial decisions. Only current costs and values matter.
Examples & Analogies
If you've spent $300 fixing an old car, that money is gone — it's a sunk cost. If you then consider whether to repair the car again or buy a new one, that $300 shouldn't factor into your decision, as it won't change regardless of what you choose.

So, for the existing equipment that is defender... Now, let us draw the cash flow diagram and do the analysis.
Detailed Explanation
In this part, the cash flow diagram is introduced as a visual tool to represent financials over the equipment's lifespan. The defender’s cash flows, including the initial cost, operating costs, and salvage value at the end of its lifespan, are outlined to facilitate the equivalent annual cost (EAC) calculation. This is essential for comparing the costs between the defender and challenger using a standardized approach.
Examples & Analogies
Consider budgeting for a new car—calculating its total cost includes the purchase price, yearly maintenance, and what you can get back when selling it later. Visualizing these cash flows helps you decide which option costs less in the long run.
