Calculating Depreciation
Unlock Audio Lesson
To begin with, let's touch upon how we calculate the yearly depreciation of a machine. Can anyone tell me what depreciation is?
Isn’t it the reduction in value of the machine over time?
Exactly! If we look at our example, we have a machine worth 28 lakh and a depreciation rate of 40%. What would the depreciation for the first year be?
It's 0.4 times 28 lakh, right? So, that’s 11,20,000 rupees!
Perfect! This means after the first year, the book value is 16,80,000. Can anyone explain why knowing the book value is important?
It helps us assess how much the machine is worth for accounting purposes and when deciding to sell or replace it.
Exactly! The depreciation helps in understanding the machine’s financial impact.
Annual Costs
Unlock Audio Lesson
Now that we’ve calculated depreciation, let’s talk about annual costs. What do you think should be added to calculate the total annual cost of a machine?
We should add the depreciation to the operating and maintenance costs, right?
Right! For the first year, if operating costs are 12 lakh, what would be the total annual cost?
That’s 11,20,000 plus 12,00,000, so it’s 23,20,000 rupees!
Excellent! And in the second year, if the maintenance cost increases, how does that affect our decision to replace the machine?
We might need to analyze if the total costs are still justifiable compared to a new machine.
Correct! Keeping track of these costs helps to evaluate when it’s financially sensible to replace the equipment.
Replacement Timing
Unlock Audio Lesson
Let's explore how we determine when to replace machinery. Dr. James Douglas suggested comparing estimated costs, what do you think that means?
It means if the costs to maintain the old machine exceed the average costs of a new one, we should replace it?
Exactly! That’s the minimum cost approach. Now, what about the maximum profit method?
We would replace the machine when its estimated profits are lower than those of the new machine!
Great job! Each method allows us to analyze from different perspectives. Why is it crucial to consider both?
Because one focuses on costs while the other emphasizes profits, giving a fuller picture of financial health.
Precisely! By understanding these methods, businesses can optimize their machinery investments.

Detailed Summary
This section presents methods to calculate depreciation on machinery, analyze annual costs, and provide strategies for replacing older equipment with newer models. The calculation of depreciation is crucial to determine the book value of machinery over time, which is calculated using a fixed percentage of the book value at the end of the previous year. The annual costs for operating and maintaining the machinery are added to annual depreciation to arrive at the total annual cost for each year.
Furthermore, cumulative costs and their averages over usage periods help to identify the machine's economic life. Two primary methods discussed are the minimum cost and maximum profit methods for evaluating replacements. The minimum cost approach advocates replacing machinery when the estimated annual cost of the old machine exceeds the average annual cumulative cost of the proposed replacement. In contrast, the maximum profit method suggests replacing equipment when the profit from the current machine falls below the average profit of the new machine. Moreover, the section briefly mentions the payback period method to compare how long it takes for the machinery to generate enough profit to recover the initial investment. The discussions underscore the significance of timely and informed decision-making regarding machinery investment to enhance business profitability.

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 the first year, to calculate the depreciation of an asset, you multiply the depreciation rate by the book value of the asset. Here, the book value of the machine is ₹28,00,000, and the depreciation rate is 40% or 0.4. By performing the calculation 0.4 multiplied by ₹28,00,000, you get a depreciation amount of ₹11,20,000. This reduction reflects the wear and tear or decrease in value of the machine over the year.
Examples & Analogies
Imagine you buy a new smartphone for ₹28,000. If it depreciates by 40% in the first year, it would mean that over the year, your phone loses ₹11,200 in value due to factors like wear, outdated technology, or market trends. At the end of the year, it is worth ₹16,800.
Book Value at the End of the First Year

So, now you calculate the book value at the end of the first year, so what is the book value at the beginning of the 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 determine the book value at the end of the first year, you take the initial purchase price of the machine, which is ₹28,00,000, and subtract the depreciation calculated for the first year, ₹11,20,000. This calculation shows how much value the machine retains after one year of use, resulting in a book value of ₹16,80,000.
Examples & Analogies
Consider the smartphone again, which started at ₹28,000 and lost ₹11,200 in value. Now, after one year, the book value of your phone is ₹16,800, signifying how much you would get if you sold it today.
Depreciation Calculation for the Second Year

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, you compute the depreciation again using the same rate of 40%. This time, you apply it to the new book value, which is ₹16,80,000. Thus, you multiply ₹16,80,000 by 0.4 to find that the second-year depreciation is ₹6,72,000. This shows that depreciation can vary from year to year based on the asset's current value.
Examples & Analogies
Using the phone example, after one year it’s now worth ₹16,800. If it depreciates again by 40%, it loses another ₹6,720 in value this year, indicating that the loss of value continues as the phone ages.
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.
So, what is the book value at the end of the 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 10,8000.
Detailed Explanation
At the end of the second year, to find the new book value, you subtract the second-year depreciation from the book value at the end of the first year. With the first-year book value at ₹16,80,000, and the depreciation being ₹6,72,000, the calculation results in a final book value of ₹10,80,000 for the end of the second year.
Examples & Analogies
In our smartphone example, after the first year, your phone was worth ₹16,800. By the end of the second year, losing another ₹6,720 means it is now valued at ₹10,080 — illustrating how quickly devices can lose value.
Annual Costs Calculation

So, let us work it for the second year.
So, like this you calculate the depreciation for all the years and the corresponding book values also you have to estimate. Now you can estimate the annual cost by adding the operating and the maintenance cost as the depreciation.
Detailed Explanation
To estimate the annual costs of the machine, one would add the depreciation calculated earlier to both the operating costs and maintenance costs. Doing this for each subsequent year helps keep a clear picture of total expenses associated with operating the machine. This annual cost informs budgetary considerations and guides financial planning.
Examples & Analogies
Think of the running costs of your smartphone, which include maintenance (like screen protectors or cases) and its depreciation. By keeping track of these costs each year, you can understand the total expense of owning the phone over time.
Cumulative Cost and Average Annual Cumulative Cost

Then you can calculate the cumulative cost, then find the average annual cumulative cost. So, like we did for the earlier old loader or the current loader or the defender.
Detailed Explanation
Cumulative costs represent the total costs incurred up to a certain year, including depreciation and operating costs. To find the average annual cumulative cost, you divide the cumulative cost by the cumulative usage or the number of years. This gives a per-year average that helps in analyzing long-term costs against usage.
Examples & Analogies
Similar to budgeting for your monthly expenses, where you aggregate previous months' spending and find an average. If the cumulative total for your phone expenses is ₹60,000 over three years, your average annual cost would be ₹20,000 per year.
Replacement Justification

So, can you see here? So, you can see, here it is 17,99,000, here it is 17,47,000. So, it justifies the replacement of your proposed loader with the old loader because the minimum average annual cumulative cost for the challenger is lesser when compared to the old loader which is higher.
Detailed Explanation
The comparison of average annual cumulative costs between the old loader and the proposed loader indicates that the proposed loader has a lower costs ratio, suggesting financial efficiency. Consequently, it justifies a decision to replace the old loader with the new proposed loader to optimize costs.
Examples & Analogies
Consider replacing an old car with a new model; if the new car’s annual operating costs are substantially lower than the old car’s, it shows you would save money over time, making it a wise financial decision.
Dr. James Douglas's Replacement Guidelines

So, the decision to replace the equipment is made when the estimated annual cost of the current machine for the next year exceeds the minimum average annual cumulative cost of the proposed machine.
Detailed Explanation
Following Dr. James Douglas's guidelines, replacement decisions are made based on cost-effectiveness. If the projected costs of maintaining the existing machine rise above the average costs calculated for the proposed new machine, then it indicates that the old machine should be replaced.
Examples & Analogies
This is akin to deciding whether to continue repairing an aging vehicle. If repair costs surpass what you would pay for a more reliable new vehicle, the sensible decision is to purchase the new one to avoid ongoing high costs.
