Understanding Depreciation
Unlock Audio Lesson
Today, we will begin by discussing how to calculate depreciation. Can anyone tell me what depreciation represents for a machine?
Isn't it the reduction in value over time?
Exactly! We’ll use a formula for our loaders: Depreciation D is calculated as 0.4 times the book value. Can someone apply this to calculate for the first year if the book value is 28 lakh?
So, D = 0.4 times 28,00,000, which equals 11,20,000 rupees!
Great! Now, how do we find the book value at the end of the first year?
Subtract the depreciation from the initial cost, which is 28 lakh minus 11.2 lakh, giving us 16.8 lakh.
Perfect! Remember, the book value helps us understand how much the machine is worth at any time.
To wrap up, depreciation helps assess a loader's value over time, ensuring we understand the financial implications better.
Calculating Annual Costs
Unlock Audio Lesson
Moving on, let's talk about total annual costs, incorporating operating and maintenance costs. How do we calculate this?
We just add the annual depreciation to the maintenance costs, right?
Exactly! For the first year, if maintenance is 12 lakh, we would do 11.2 lakh plus 12 lakh. What does that give us?
That’s 23.2 lakh as the annual cost for the first year!
Correct! And how about the second year where depreciation went down to 6.72 lakh and maintenance increased to 12.6 lakh?
The annual cost for the second year would be 19.32 lakh then.
Well done! Understanding these costs helps manage our budget efficiently.
Evaluating Replacement Decisions
Unlock Audio Lesson
Now, let's evaluate when to replace our loader. What factors should we consider?
We should look at the annual costs and how they compare to new loaders.
Exactly right! According to Dr. James Douglas, when the estimated cost for the current loader exceeds the average annual cumulative cost of the proposed, that's our signal. Can you work out a scenario?
If our current loader's cost for the next year is 19.04 lakh, how does that compare to the proposed average cost of 17.47 lakh?
Excellent example! Since 19.04 lakh exceeds 17.47 lakh, it indicates a need for replacement.
So, the main takeaway is a consistent review of costs will lead to better financial decisions over time.
Comparing Economic Lifetimes
Unlock Audio Lesson
Now let's delve into economic life of our loaders. What does this term mean?
It refers to the time period where the loader is most cost-effective, right?
Yes, exactly! For the proposed loader, we found it was 9 years based on our cumulative costs. Can anyone share what we found for the old loader?
The old loader's economic life is 8 years.
Correct! Comparing these two, what does it suggest about replacing the old loader?
It seems that the proposed loader provides better value beyond 8 years!
Exactly! Economic life is crucial and informs when it's financially sensible to upgrade equipment.

So, depreciation for the first year is nothing but 0.4 into book value. D = 0.4 × 28,00,000 = 11,20,000 rupees
Detailed Explanation
Depreciation refers to the reduction in value of an asset over time as it is used. In this case, the first year's depreciation is calculated by multiplying the book value of the loader by 0.4 (or 40%). The book value at the start is 28,00,000 rupees. Thus, the depreciation for the first year is 11,20,000 rupees.
Examples & Analogies
Think of a new car that you buy for 28,00,000 rupees. As you drive it each year, it loses value. The first year's depreciation represents how much value it loses during that year, which in this case is similar to the loader. This helps you understand that assets lose value just like a car does after being driven.
Calculating Book Value After Year One

So, now you calculate the book value at the end of first year, so what is the book value at the beginning of year that is nothing but your purchase price of the machine 28 lakh minus the depreciation for the first year. That is nothing but 11,20,000, that gives you the book value at the end of the first year as 16,80,000...
Detailed Explanation
To find the book value at the end of the first year, we start with the initial purchase price of 28,00,000 rupees and subtract the depreciation calculated for that year (11,20,000 rupees). This results in a new book value of 16,80,000 rupees at the end of the first year.
Examples & Analogies
Using the earlier example of buying a car for 28,00,000 rupees, if you realize that the car has lost value over the first year, you subtract the depreciation (how much value it has lost) from the original price to know how much it is worth now. That concept is the same for the loader.
Recurring Depreciation and Book Value Calculation

So, for the second year the depreciation is nothing but D2 is 0.4 into book value the end of first year. D = 0.4 × 16,80,000 = 6,72,000 rupees...
Detailed Explanation
For the second year, the calculation of depreciation follows the same method. We take 40% of the book value at the end of the first year, which is now 16,80,000 rupees, resulting in a second year's depreciation of 6,72,000 rupees. This depreciation again reduces the book value, calculated by subtracting this depreciation from the book value at the end of the first year.
Examples & Analogies
Imagine you buy a tech gadget that loses value each year. In the second year, you would similarly calculate how much value is lost based on its new worth, just like the loader’s book value decreases after each year’s depreciation calculation.
Annual Cost Calculation

So, what is the annual cost for the first year? Your operating in the maintenance cost for the first year is 12 lakh and your depreciation for the first year is 11,20,000, so your annual cost will be Annual cost of first year = 11,20,000+12,00,000 = 23,20,000 rupees...
Detailed Explanation
The annual cost of running the loader includes both operational and maintenance costs plus the yearly depreciation. For the first year, we calculate the total by adding operational costs (12,00,000 rupees) and depreciation (11,20,000 rupees), which totals to 23,20,000 rupees. This total cost is essential for understanding how economically viable the machine is.
Examples & Analogies
Just like budgeting for running a car involves considering gas, insurance, and how much value it loses each year, calculating the loader’s annual costs involves summing its depreciation and service costs. This helps in determining whether owning it is financially sensible.

So, now let us compare the average annual cumulative cost of the proposed loader and the old loader... the minimum average annual cumulative costs is 17,99,541.
Detailed Explanation
After calculating the annual costs for each year, cumulative costs can be evaluated to find average annual costs. It is important to compare these average costs between the new (proposed) loader and the old loader. Cumulative costs reflect the total investment over time, helping to determine the economic longevity or viability of the loader.
Examples & Analogies
Think of keeping track of expenses for a new car versus an old car over the years to see which one costs more to maintain and run. Similarly, understanding the cumulative costs allows for comparing overall expenses against economic value when deciding whether to keep or replace a machine.

So, Dr. James Douglas has given a guideline for this minimum cost approach to decide when to replace the old machine with the new machine...
Detailed Explanation
Dr. James Douglas outlines a guideline for deciding when a loader (or any machine) should be replaced. The replacement decision is justified when the future estimated annual cost of the current machine exceeds the minimum average annual cumulative cost of a new machine. The goal is to minimize total costs by making timely replacement decisions.
Examples & Analogies
Just like a homeowner might decide to replace an old heating system when the repair costs start exceeding the cost of a new, more efficient system, this guideline helps businesses know the right time to invest in new equipment versus pouring more money into old machinery.
