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.
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.
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.
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.
This is the reduction in value of the machine calculated using a rate and the initial book value.
Represents the current worth of the asset after the deduction of accumulated depreciation.
Combines operational costs and depreciation to assess the overall cost per year of the asset.
For a machine costing 28 lakh with a 40% depreciation rate in its first year, its depreciation would be 11,20,000 rupees. Thus, the book value at the end of the first year is 16,80,000 rupees.
In the second year, with a book value of 16,80,000 rupees, the depreciation would be 6,72,000 rupees, resulting in a book value at the end of the second year of 10,80,000 rupees.
For buildings and machines, depreciation steps in, A smart investor’s story where values begin.
Once, there was a machine that worked all day. Each year, as it aged, its value would sway. By knowing its worth at the end of each year, The owner would decide if replacing it was near.

The value of an asset after deducting depreciation as per accounting standards.
The reduction in the value of an asset over time, often used for accounting and tax purposes.
The total cost incurred to maintain and operate an asset within a year, including depreciation and operational costs.
This section describes the steps for calculating book value and depreciation for a machine over the first and second years.
In this section, learners are guided through the process of calculating the book value of a machine at the end of its first and second years, including the derivation of depreciation values. The significance of annual costs, cumulative costs, as well as guidelines for equipment replacement are also discussed.
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):
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:
For the second year, the depreciation is recalculated using the new book value:
Depreciation for Year 2 (D2):
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:
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:
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.
