3.1. Profit Calculation for Loaders

So, depreciation for the first year is nothing but 0.4 into book value. D = 0.4 × 28,00,000 = 11,20,000 rupees.

In this chunk, we calculate the depreciation for the first year of a loader. Depreciation is an accounting method that allocates the cost of a tangible asset over its useful life. Here, the depreciation rate is given as 40% (0.4), and it is multiplied by the initial book value of the loader, which is 2,800,000 rupees. Therefore, the depreciation for the first year amounts to 1,120,000 rupees.

Imagine you bought a new car for 28 lakh rupees, and its value is expected to decrease by 40% in the first year. Just like how the car's value decreases due to use and age, the 1.12 lakh rupees represents how much less the loader is worth after one year.

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.

To find the book value at the end of the first year, you subtract the first-year depreciation (1,120,000 rupees) from the initial purchase price (2,800,000 rupees). The calculation results in a book value of 1,680,000 rupees at the end of the year. This value represents what the loader is worth after one year of usage.

Think of it as having a smartphone that you bought for 28,000 rupees. If its value decreases due to wear and tear and is estimated to be worth 16,800 rupees after a year, that's its book value at the end of that 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.

The second year depreciation is calculated again at the rate of 40% on the new book value, which is now reduced to 1,680,000 rupees. This results in a new depreciation of 672,000 rupees for the second year. This demonstrates how the depreciation changes based on the book value, which decreases each year.

If you apply the same depreciation method to your smartphone, after a year, it might be worth 16,800 rupees. If it's again depreciated by 40%, you would subtract 6,720 rupees from its current value to find out how much less it’s worth this 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.

After determining the second year’s depreciation, we find the new book value by subtracting this year's depreciation (672,000 rupees) from the book value at the end of the first year (1,680,000 rupees). This leads to a new book value of 1,080,000 rupees at the end of the second year, further reflecting the reduced value of the loader over time.

Using our smartphone example, after depreciating it down to 16,800 rupees, if it loses an additional 6,720 rupees in value this year, its new worth would be 10,800 rupees at the end of the year.

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.

The annual cost of operating the loader consists of the depreciation and any additional operating and maintenance expenses. By summing these values for each year, you arrive at the total annual cost, which is crucial for financial planning and analysis.

Think of your car expenses. Each year, you not only consider how much your car lost in value but also how much you spend on fuel, insurance, and repairs. Adding all these costs gives you the total cost of owning that car.

So, how will you calculate the average annual cumulative cost? It is nothing but your the cumulative cost divided by the cumulative usage of the machine.

The average annual cumulative cost is a measure that helps determine the overall financial impact of using the loader over time. This is calculated by dividing the total cumulative cost by the total amount of usage (measured in years, hours, or operations). This allows for a fair comparison between different machines and their costs.

If you keep track of your car expenses over a few years, you can see how much you've spent in total and divide that by how many years you've had the car. This gives you a clearer picture of how economical your car has been for you.

Now you can compare the average annual cumulative cost of the proposed loader and the old loader. You can see the average annual cumulative costs minimum is 17,99,541.

By comparing the average annual cumulative costs, decision-makers can evaluate which loader is more cost-effective over time. A lower average annual cumulative cost suggests it may be financially wise to replace the older loader with the proposed one, which has shown to have lower costs associated with it.

When shopping for new appliances, you often compare their long-term costs, like energy bills, against the older model you currently own. If you find a newer model that shows it will save you money annually, it's a good reason to consider replacing the old one.

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.

In decision-making for replacements, one should analyze the estimated annual costs of maintaining the current equipment versus the average costs associated with a new machine. When the costs of keeping the current machine become higher than those of the new proposed machine, it justifies the need for replacement.

If your car requires constant repairs each year and its maintenance costs exceed the monthly payments on a new car that would be more reliable, it’s an obvious sign to consider buying a new car.
