Understanding Depreciation
Unlock Audio Lesson
Today we will discuss how to calculate depreciation for the first year. Recall that depreciation is the reduction in the value of an asset over time. For our machine, the first-year depreciation can be calculated as 0.4 times the initial book value. What do you think the initial book value is?
Is it 2.8 million rupees?
Exactly! So, we compute the depreciation as 0.4 times 2.8 million, which gives us 1.12 million rupees. This amount is the depreciation for the first year.
What happens to the book value after that?
Great question! The book value at the end of the first year is calculated by subtracting the depreciation from the initial book value. So, it would be 2.8 million minus 1.12 million, leaving us with 1.68 million rupees.
Why do we need to compute the book value?
The book value is essential as it helps us understand the remaining worth of the asset and is crucial for determining future depreciation.
Can we apply this calculation for the second year?
Absolutely! For the second year, we use the new book value, which is 1.68 million rupees, and calculate the depreciation again. Keep in mind that each year's depreciation may change based on the book value.
To summarize, depreciation helps us understand the loss of value of our machinery over time, and we calculated the first year's depreciation as 1.12 million rupees.
Annual Cost Calculation

Now, let's move on to how we calculate the annual costs, which include both depreciation and operational costs. Can anyone tell me what the operational costs for the first year were?
I remember it was 1.2 million rupees.
That's correct! So, to find the total annual cost for the first year, we add the depreciation of 1.12 million to the operating cost of 1.2 million. Can anyone calculate that for me?
That would be 2.32 million rupees.
Excellent! Now, this gives us the total cost for the first year. Knowing the annual costs helps businesses in budgeting and financial analysis.
What about the second year? How do we handle that?
For the second year, we'll first compute the new depreciation from the end of the first year book value, and also you will have to consider any changes in operational costs.
What do we do with these cumulative costs they mentioned?
Cumulative costs give us an overall view of the expenses over multiple years which aids in understanding the machinery's economic life.
Remember, the first year’s annual cost was 2.32 million rupees, and it’s essential to keep track of these figures to enable effective financial planning.
Economic Life Consideration
Unlock Audio Lesson
Today, we will also discuss the concept of economic life of the machinery. Why do you think knowing the economic life is important?
Is it to know when we should replace the machine?
Exactly! The economic life tells us how long the machine remains cost-effective. We assess it by comparing cumulative costs over time. Can someone tell me about the minimum average cumulative cost we talked about?
I believe it’s around 17.99 million for the proposed loader?
Correct! So, if the estimated annual cost of our current machine exceeds this minimum, what should we do?
We should consider replacing it!
Yes! Replacement decisions also consider expected profits. Ultimately, decisions depend on minimizing costs and maximizing profits.
Does this imply that keeping machinery longer is always bad?
Not necessarily, but once a machine starts costing more than it's worth, that's a signal to replace it. This essential analysis helps in managing resources efficiently.
Introduction & Overview
Read a summary of the section's main ideas. Choose from Basic, Medium, or Detailed.
Quick Overview
Standard
It covers the computation of first-year depreciation, the adjustments to the book value at the end of each year, annual costs including depreciation and operating expenses, and how to assess economic life based on average cumulative costs.
Detailed
In this section, we examine the method of calculating the depreciation and book value of equipment, specifically focusing on the first year. Depreciation for the first year is calculated as 0.4 times the book value at the start, and this value is subtracted from the initial purchase price to determine the book value at year-end. The annual costs encompass both depreciation and operating expenses. We also explore methods for comparing costs and benefits to determine the economic life of the machinery. Furthermore, Dr. James Douglas’s approach to replacement analytics is introduced, which addresses when to replace machinery based on cost and profit optimization.

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
In this chunk, we calculate the depreciation for the first year of a machine using a specific rate applied to its initial book value, which is the purchase price. The formula is simple: multiply the initial book value of the machine by the depreciation rate, which is 0.4 in this case. Thus, if the machine's initial value is 28,00,000 rupees, the depreciation for the first year is calculated as 0.4 × 28,00,000 = 11,20,000 rupees.
Examples & Analogies
Imagine you bought a new car for 28 lakh rupees, and the dealer told you that the car will depreciate at a rate of 40% each year. This means that after the first year, your car’s value decreases significantly, just like how we calculated that 11,20,000 rupees is lost in value for the machine.
Calculating the Book Value at the End of the First Year

So, now you calculate the book value at the end of the first year. That is nothing but your purchase price of the machine 28 lakh minus the depreciation for the first year. That gives you the book value at the end of the first year as 16,80,000.
Detailed Explanation
After determining the depreciation for the first year, we can calculate the book value at the end of the first year. The book value is essentially the original cost of the asset minus the amount it has depreciated. In this case, the initial cost is 28 lakh rupees, and we subtract the depreciation (11,20,000 rupees) to get the book value of 16,80,000 rupees at the end of the first year.
Examples & Analogies
Think of it like a smartphone you bought for 28,00,000 rupees, which loses some value every year. If it loses 11,20,000 rupees in value after a year, its worth is now 16,80,000 rupees. This is how depreciation works to affect its value.
Depreciation and Book Value for the Second Year

So, for the second year, the depreciation is nothing but D2 is 0.4 into book value at the end of first year, D = 0.4 × 16,80,000 = 6,72,000 rupees.
Detailed Explanation
Similar to the first year, we calculate the depreciation for the second year using the book value at the end of the first year. Applying the same depreciation rate of 40% to the updated book value of 16,80,000 rupees gives us a depreciation amount of 6,72,000 rupees for the second year.
Examples & Analogies
If we go back to our car example, just like your car's value would continue to decrease every year, after the first year, you would determine how much less it's worth and then calculate how much more it will lose in value in the second year, which in our case, is a loss of 6,72,000 rupees.
Calculating Book Value at the End of the Second Year

Now calculate the book value at the end of the second year, it is nothing but book value at the end of the first year minus the depreciation for the second year: 16,80,000 minus 6,72,000 gives us the book value at the end of second year as 10,08,000.
Detailed Explanation
To find the book value at the end of the second year, we take the book value at the end of the first year and subtract the second year's depreciation. The resulting value reflects the new worth of the machine after two years of depreciation: 16,80,000 minus 6,72,000 results in a book value of 10,08,000 rupees for the end of the second year.
Examples & Analogies
If your smartphone is now worth 16,80,000 rupees after one year, you apply the same principle and realize after the second year, its worth drops further to 10,08,000 rupees. This continuous calculation shows how assets depreciate over time.
Calculating Annual Costs

Annual cost for the first year is 12 lakh and your depreciation for the first year is 11,20,000, so annual cost will be: Annual cost of first year = 11,20,000 + 12,00,000 = 23,20,000 rupees.
Detailed Explanation
In this section, we combine both the operating costs and the depreciation to determine the annual cost for the machine. The total annual cost for the first year is calculated by adding the depreciation amount (11,20,000 rupees) to the operating and maintenance costs (12,00,000 rupees), resulting in a total of 23,20,000 rupees.
Examples & Analogies
Using the car analogy once again, consider how much you'll spend on maintaining the car plus the loss in value (depreciation). For instance, if you don't just consider how much the car loses value but also the yearly service costs, you find out total expenses for the year.
