Today, we’re diving into the Challenger's Equivalent Annual Cost. Can anyone tell me what we mean by 'Equivalent Annual Cost'?

Student 1
Student 1

Is it the total cost of owning an equipment annually?

Teacher
Teacher

Exactly! It reflects the annualized costs associated with using an asset, including purchase price, operating costs, and salvage value. Now, we see that the Challenger's operating cost is ₹90,000, which is important. Why do you think it's necessary to compare this with the Defender?

Student 2
Student 2

To see which one is cheaper to operate over time?

Teacher
Teacher

Right! This helps us make a financial decision regarding replacement. Remember, we have to consider future cash flows and salvage values too.

Student 3
Student 3

What’s the Challenger's salvage value?

Teacher
Teacher

Good question! The Challenger's salvage value after five years is ₹12,00,000. We will use this in our calculations.

Teacher
Teacher

To remember: EAC involves costs to keep, cash flows to expect, and values at the end. Let's keep this structure in mind as we proceed further.

Now, let’s talk about which costs we should focus on for the Defender and Challenger analysis. What costs should we ignore?

Student 4
Student 4

Sunk costs?

Teacher
Teacher

Correct! Sunk costs, as they can't be recovered. We should focus only on current market value and relevant operating costs.

Student 2
Student 2

What is the current market value for the Defender?

Teacher
Teacher

It's ₹22,50,000! And its salvage value is now projected to be ₹6,00,000 over five years. We’ll use these numbers to calculate EAC.

Student 1
Student 1

I remember you mentioned ignoring book value too. Why?

Teacher
Teacher

That's right! The book value doesn't reflect the real decision-making since we only care about the current trading value.

Teacher
Teacher

Key takeaway: Focus on present values and expected future cash flows. Let’s keep this clear in our analysis.

Next, let’s calculate the Equivalent Annual Costs. Who remembers the formula for converting present value to EAC?

Student 3
Student 3

It involves the uniform series capital recovery factor?

Teacher
Teacher

Correct! For the Defender, what do we calculate first?

Student 4
Student 4

The initial cost, which is ₹22,50,000.

Teacher
Teacher

Exactly! We multiply that by the factor we derived. Can anyone recall what that factor was?

Student 1
Student 1

It was 0.2638 for the 10% interest rate over five years, right?

Teacher
Teacher

Exactly! And when you multiply, what do you get?

Student 1
Student 1

About ₹5,93,550!

Teacher
Teacher

Now, add the operating cost of ₹1,35,000 and subtract the equivalent annual cost of the salvage value. What’s the final outcome for the Defender?

Student 4
Student 4

I think it rounds out to ₹6,30,270.

Let’s compare our EACs now. What did we find for the Challenger's equivalent annual cost?

Student 2
Student 2

It was around ₹6,18,890 after calculating everything!

Teacher
Teacher

Correct! So, who remembers which machine has the lower EAC?

Student 3
Student 3

The Challenger is less!

Teacher
Teacher

Exactly right! Our analysis indicates we should replace the Defender with the Challenger due to lower costs.

Student 1
Student 1

So, does this mean we simply always choose the lower EAC?

Teacher
Teacher

Generally, yes, but also keep in mind other practical factors, like reliability and downtime. So we focus on EAC but pay attention to the bigger picture too.

Teacher
Teacher

Remember, key elements are cost, cash flows, and equipment life! That's how we make informed decisions.

This section provides a comprehensive analysis of the Challenger's Equivalent Annual Cost, comparing it to the Defender's costs, and using various financial factors like operating costs, salvage value, and interest rates to inform a replacement decision.

Detailed

Summary of Challenger's Equivalent Annual Cost

In this section, we explore the concept of Equivalent Annual Cost (EAC) focusing on a proposed equipment, referred to as the 'Challenger', in comparison with the existing equipment known as the 'Defender'. The main objective is to determine whether the Defender should be retained or replaced based on financial metrics, specifically EAC.

Key Points Covered:

  1. Cost Comparison: The Challenger's operating and maintenance cost is significantly lower at ₹90,000 compared to the Defender's ₹1,35,000.
  2. Salvage Value and Investment: The Challenger has a salvage value of ₹12,00,000 after five years and an assumed investment cost of 10% per year.
  3. Sunk Costs: The analysis emphasizes the irrelevance of sunk costs and old estimates, focusing solely on current values and market trading prices for decision-making.
  4. Financial Analysis: Through cash flow diagrams and calculations, the Equivalent Annual Cost for both machines is derived, taking into account initial costs, operating costs, and salvage values over time.
  5. Decision Making: Ultimately, the process leads to a recommendation on whether to retain the Defender or transition to the Challenger, solidified through EAC metrics assessment.

This analysis not only methodically dissects the financial implications of equipment replacement but also provides a structured approach to evaluating future investments and operational costs.

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 defender and challenger equipment, emphasizing that the challenger is a proposed new equipment and has a lower annual operating and maintenance cost (90,000) compared to the defender (135,000). It's important to analyze these costs to determine whether to replace the defender with the challenger based on financial benefits.

Examples & Analogies

Imagine you are considering buying a new car (challenger) because it offers better fuel efficiency and lower maintenance costs compared to your current car (defender). By comparing these costs, you can decide if upgrading is a smart financial move.

Understanding Sunk Costs

And 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, this is a cost which is spent and it is lost, it cannot be recovered.

Detailed Explanation

Sunk costs refer to costs that have already been incurred and cannot be recovered. In this case, the estimated book value of the defender is 3,80,000, while the trading value is 22,50,000. The difference represents money spent in the past that should not influence current decision-making about replacing the asset.

Examples & Analogies

Think of it like the money you spent on a non-refundable concert ticket. Even if you're sick on the day of the concert and can't go, the money spent is gone and shouldn't affect your decision to buy a completely new ticket for another event.

Now the first cost of the defender is the current, this is nothing but your current trading value of your machine, that is nothing but 22,50,000. Every year the operating cost is going to be same and it is found to be 1,35,000, so the remaining life of the machine estimated is 5 years, you can see 5 years. At the end of 5th year, when you sell it you are going to get a cash inflow of 6,00,000.

Detailed Explanation

The chunk discusses calculating the equivalent annual cost by considering the initial/current trading value of the defender, which is 22,50,000, and the ongoing operating costs of 1,35,000 over a projected remaining life of 5 years. The anticipated salvage value at the end of year 5 is 6,00,000. This information helps in determining the total outflow against the inflows over time to assess the financial viability of the defender.

Examples & Analogies

Imagine you're planning to sell your house. You calculate the cost of staying in the house (mortgage, maintenance costs) over the next five years, while also predicting how much you'll sell it for after that time. The goal is to gauge whether keeping or selling is the better financial choice.

Final Comparison of Costs

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, and they are equal, they are already annualized cost, so you need not convert them. Now let us see how it is done?

Detailed Explanation

In this section, the equivalent annual cost (EAC) of the defender has been calculated and is defined. The operating and maintenance costs were treated as annualized costs, eliminating the need for conversion. This segment emphasizes the importance of understanding all costs associated effectively and summarizing their totals to clearly evaluate the decision between keeping or replacing equipment.

Examples & Analogies

Consider it like a monthly budget for living expenses. You already know your living costs (rent, food) annually without needing to convert them into a different format. Next, you sum it up with your other financial liabilities to make the best budgetary decision.

So, for the new equipment challenger, the initial cost is given as 27,50,000... Similar manner, you can find it.

Detailed Explanation

Here, the equivalent annual cost for the new equipment (challenger) is outlined, starting with the initial cost of 27,50,000 followed by operating costs of 90,000. The process for evaluating these expenses is similar to the defender's, connecting back to the prior analysis to ensure both options are assessed consistently.

Examples & Analogies

It's like weighing the financial implications of a new smartphone against your old one. You factor in the purchase price, ongoing service costs, and potential resale value—all using similar methods as you did with your first device to determine the best choice.

Now let us compare, from the above calculations you confine that the equivalent uniform annual cost of the defender is 630270... hence it is advisable to replace your defender with a challenger.

Detailed Explanation

The final analysis directly compares the calculated equivalent annual costs of the defender and challenger, concluding that the challenger presents a lower annual cost (6,18,890 vs. 6,30,270). This comparison leads to the recommendation for replacing the current equipment with the more cost-effective option.

Examples & Analogies

Think of it like analyzing two different subscription plans for a streaming service. If one plan has lower annual costs and better features, it makes financial sense to switch from the more expensive plan to the more economical one. This careful comparison is exactly what allows you to make the best decision about subscriptions—or in this case, equipment.
