Calculating First Year Depreciation
Unlock Audio Lesson
Today, we are learning about how to calculate the first-year depreciation for our machine. The formula we'll use is pretty straightforward – we multiply the book value by the depreciation rate of 40%. So, who can tell me what the book value is at the beginning?
Isn't it the purchase price of the machine, which is 28 lakh?
Exactly right! Now using that, we calculate depreciation for the first year as D1 = 0.4 times 28,00,000. What does that give us?
That would be 11,20,000 rupees.
Great! Now, if we take the initial price and subtract this depreciation, what is our book value at the end of the first year?
It would be 16,80,000 rupees.
Perfect! Remember that by subtracting depreciation from the initial amount we get the end-of-year book value.
Calculating Second Year Depreciation
Unlock Audio Lesson
Now let’s move on to the second year. We need to recalculate depreciation using the new book value. What’s the new book value?
It’s 16,80,000 rupees.
Right again! So how do we calculate the depreciation for the second year?
We do D2 = 0.4 times 16,80,000, which equals 6,72,000 rupees.
Excellent! Now, how do we find the book value at the end of the second year?
By subtracting the second year's depreciation from the first year's end value, which is 10,80,000 rupees.
Correct! That's important to remember: book value changes every year based on the depreciation.
Calculating Annual Costs
Unlock Audio Lesson
Now, let's calculate the annual costs. Who remembers how to calculate the first year's annual cost?
We need to add the depreciation to the operating costs.
Correct! For Year 1, it’s 11,20,000 plus 12,00,000. What does that come to?
That gives us 23,20,000 rupees.
Perfect! Now, for Year 2, what would it be?
It would be 6,72,000 plus 12,60,000, which gives us 19,32,000 rupees.
Well done! The annual cost becomes crucial for evaluating the machine’s efficiency over time.
Cumulative Costs and Replacement Decisions
Unlock Audio Lesson
Lastly, let's look at cumulative costs. Why do you think they’re important when deciding on replacing a machine?
Because they help us understand if continuing to use the current machine is economically viable.
Exactly! When does Dr. Douglas suggest we should think about replacing the old machine?
When the estimated annual costs exceed that of a proposed new machine, right?
Correct again! Always keep an eye on those costs. It’s what fuels the decision to invest in new equipment.

Book Value Calculation for Second Year
This section focuses on calculating the depreciation and book value of a machine over its first and second operational years. Starting with the first year's depreciation, given a rate of 40%, the depreciation is computed as:
Depreciation for Year 1 (D1):
$$
D_1 = 0.4 × 28,00,000 = 11,20,000 ext{ Rupees}
$$
Next, the book value at the end of the first year can be calculated by subtracting this depreciation from the initial purchase price:
Book Value End of Year 1:
$$
ext{Book Value at End of Year 1} = 28,00,000 - D_1 = 28,00,000 - 11,20,000 = 16,80,000 ext{ Rupees}
$$
For the second year, the depreciation is recalculated using the new book value:
Depreciation for Year 2 (D2):
$$
D_2 = 0.4 × 16,80,000 = 6,72,000 ext{ Rupees}
$$
Once again, subtract this depreciation from the book value at the end of year one to find the book value at the end of year two:
Book Value End of Year 2:
$$
ext{Book Value at End of Year 2} = 16,80,000 - D_2 = 16,80,000 - 6,72,000 = 10,80,000 ext{ Rupees}
$$
Additionally, the section introduces the concept of annual costs, combining depreciation and other operational costs. The summaries of the annual costs for each year are computed as follows:
-
Annual Cost for Year 1:
$$
ext{Annual Cost}_1 = D_1 + ext{Operating Cost}_1 = 11,20,000 + 12,00,000 = 23,20,000 ext{ Rupees}
$$ -
Annual Cost for Year 2:
$$
ext{Annual Cost}_2 = D_2 + ext{Operating Cost}_2 = 6,72,000 + 12,60,000 = 19,32,000 ext{ Rupees}
$$
The section concludes with guidance on calculating cumulative costs and evaluating the economic life of the machine, emphasizing the methods for assessing when to replace existing equipment based on cost-effectiveness. This insight is framed by Dr. James Douglas' guideline, which recommends replacement when the estimated annual cost of an aging machine exceeds that of a proposed new machine.

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
In the second year, we need to calculate how much the asset (machine) depreciates in value again. Depreciation is a method to allocate the cost of an asset over its useful life. Here, the rate of depreciation is 40%. We take the book value at the end of the first year, which is ₹16,80,000, and multiply it by 0.4 (the depreciation rate). This means that the depreciation expense for the second year is ₹6,72,000.
Examples & Analogies
Think of depreciation like a car losing its value each year. If you bought a car for ₹16,80,000 and it loses 40% of its value in the second year, it means you would lose ₹6,72,000 in value. So, if you tried to sell it after two years, you'd get much less than the original price.

Now calculate the book value at the end of second year, it is nothing but book value at the end of the first year minus the depreciation for the second year. So, what is the book value at the end of first year? It is nothing but 16,80,000 minus your depreciation for the second year is 6,72,000 that gives me the book value at the end of second year as 10,80,000.
Detailed Explanation
To find the book value at the end of the second year, we take the book value from the end of the first year (which is ₹16,80,000) and subtract the depreciation amount calculated for the second year (₹6,72,000). This gives us the book value at the end of the second year as ₹10,80,000. This is important as it reflects how much value remains in the machine after accounting for wear and tear.
Examples & Analogies
Imagine continuing with the car analogy: after the first year, your car is worth ₹16,80,000. If in the second year it loses ₹6,72,000, its new value is ₹10,80,000. So, if you decided to sell it at the end of the second year, that's what you'd realistically get for it.
Estimating Annual Costs

So, like this you calculate the depreciation for all the years and the corresponding book values also you have to estimate.
Detailed Explanation
Understanding how to calculate depreciation and book values every year is crucial for estimating the cost of using an asset over time. This helps in making informed financial decisions, such as whether to retain or replace the asset. Each year, you will need to repeat this process to find out the depreciation amount and the book value until the asset is fully depreciated.
Examples & Analogies
It's like keeping track of how much you pay for your car every year. Each year you know how much value it has lost, which helps you understand if you should keep it for another year or consider buying a new one.

Now you can estimate the annual cost by adding the operating and the maintenance cost as the depreciation. When you add column 2 and the column 3 you will get the annual costs for every year. 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
Annual costs comprise both depreciation and other operational costs (like maintenance). For the first year, operational costs are ₹12,00,000 plus the calculated depreciation of ₹11,20,000 gives us a total annual cost of ₹23,20,000. This total cost reflects the financial burden of maintaining the asset in its first year.
Examples & Analogies
Imagine budgeting for running your car. You need to account for fuel, maintenance, and depreciation (which reflects the car's decreasing value). So, if your car costs ₹12,00,000 to operate plus ₹11,20,000 in depreciation, you would budget ₹23,20,000 for the first year.

So, like this you keep calculating for all the years with every year you can calculate the annual cost. Then you can calculate the cumulative cost, then find the average annual cumulative cost.
Detailed Explanation
Each year, you should continue calculating both annual costs and book values to keep an accurate track of your asset's financial performance. Cumulative costs are the total costs incurred up to each year, and the average annual cumulative cost helps in evaluating the cost-effectiveness of the asset over time. This analysis simplifies the decision-making related to asset management or replacement.
Examples & Analogies
Think of this like keeping track of your expenses in a notebook. You want to know how much you’ve spent over time, so you add up all your costs to find the total amount spent. The yearly average helps you budget for future expenses, aiding you in deciding whether it's worth holding onto your car or looking for a better financial option.
