Today, we will learn about depreciation, which is a way to allocate the cost of a tangible asset over its useful life. For example, if we have machinery that costs 28 lakh rupees, and we apply a depreciation rate of 40%, how would we calculate the first year's depreciation?
We would multiply the purchase price by the depreciation rate, right?
Exactly! So, 28,00,000 multiplied by 0.4 gives us what amount?
That would be 11,20,000 rupees for the first year.
Correct! Now, what would be the book value at the end of the first year?
It's the initial cost minus the depreciation, so 28 lakh minus 11 lakh 20 thousand.
That would leave us with 16 lakh 80 thousand rupees.
Great work! Always remember, the formula for depreciation is vital to calculating book value each year.
Now that we have our book values, let's calculate the annual costs. How would we find this for the first year?
We need to add the depreciation and the operating cost, which for the first year are 12 lakh.
Exactly! So, what would be the annual cost for the first year?
It would be 23 lakh 20 thousand, right? That's 11 lakh 20 thousand for depreciation plus 12 lakh for operating costs.
Right! And for the second year, what needs to change?
We calculate the new depreciation using the book value at the end of the first year, which was 16 lakh 80 thousand.
And then we add the updated operating costs to find the annual cost for the second year.
Correct! Keeping track of these values helps in planning for replacement.
As we calculate annual costs over the years, we eventually determine the economic life of the machine. What does this refer to?
It's the time period where the average cost is minimized and where we may want to consider replacement.
Correct! What factors do we consider when deciding to replace a machine?
We compare the estimated annual costs of the current machine with the minimum average annual cumulative costs of a potential replacement.
Exactly! If our current machine's costs begin to exceed the new one, we should think about replacement. Can anyone recall the economic life for the proposed loader versus the old loader, as mentioned?
For the proposed loader, the economic life is 9 years, and for the old loader, it’s 8 years.
Fantastic! That's very important for making projections and decisions for the future.
The method to determine how value decreases over time.
The amount an asset is worth after depreciation.
All costs associated with operating and maintaining machinery each year.
The period in which a machine provides economic benefit.
If a machine is purchased for 28,00,000 rupees with a 40% depreciation rate, the first-year depreciation amounts to 11,20,000 rupees.
By incorporating both operating costs and depreciation, if the annual operating cost is 12 lakh, the total annual cost for the first year comes to 23,20,000 rupees.
When machines do depreciate, their value starts to wait, accounting keeps us straight on expenses we calculate.
Imagine a car purchased for 1000 coins. Every year it loses 400 coins in value. By the end of the first year, it's worth only 600 coins. This shows how depreciation works in real life.
Remember ADOC: Annual costs = Depreciation + Operating costs.
PEACE: P = Purchase price, E = Estimate depreciation, A = Annual costs, C = Cumulative costs, E = Economic life.

The reduction in the value of an asset over time, in this case, machinery, calculated as a percentage of its book value.
The value of an asset as reported on the balance sheet, calculated as the original cost minus accumulated depreciation.
The total costs associated with owning a piece of machinery each year, including operating, maintenance, and depreciation costs.
The period over which an asset is expected to remain useful and economically viable for the owner.
This section covers how to calculate depreciation, book value, and annual costs of machinery over its lifespan, essential for equipment replacement decisions.
It details the process of calculating depreciation and book value for machinery over multiple years, using specific examples. The section also discusses how to derive the annual costs by adding operating and maintenance costs to depreciation, and outlines methods for comparing costs for decision-making on equipment replacement.
In this section, we explore the financial implications of machinery over its lifespan through annual cost calculations. The first step involves determining the depreciation of the machinery which is calculated as a percentage of the book value. For example, with a book value of 28,00,000 rupees and a depreciation rate of 0.4, the first-year depreciation is calculated as:
The book value at the end of the first year is then found by subtracting this depreciation from the initial value, resulting in:
The same procedure is followed for subsequent years, using the book values calculated previously to find depreciation and adjust for annual costs. Annual costs comprise both operating/maintenance expenses and depreciation. For instance:
Cumulative costs and average annual cumulative costs can also be calculated, leading to insights on the economic life of the machine, notably that the economic life of the machine could be around 9 years. The decision to replace equipment is based on whether future annual costs exceed the average cumulative costs of new options. Furthermore, alternative approaches such as the payback period and profit maximization offer different perspectives on when machinery should be replaced.
