Today, we will understand how to calculate depreciation. Depreciation is essentially the decrease in value of an asset over time. Can anyone tell me how we calculate it?
Isn't it 0.4 times the book value?
Exactly! So if our machine costs 28 lakh, the depreciation for the first year would be calculated as 0.4 times 28 lakh, which is 11,20,000 rupees. Remember, we can use 'D = P × r' for depreciation where 'D' is depreciation, 'P' is price, and 'r' is the rate.
What happens to the book value after that?
Good question! The new book value at the end of the first year becomes the original price minus depreciation. So, it's 28 lakh minus 11,20,000. Who can calculate that?
That would be 16,80,000!
Correct! This new book value is used for the next year's depreciation calculation.
So we keep subtracting depreciation every year?
Right! This cycle continues each year, affecting our financial assessments.
In summary, remember the formula and the book value adjustments. Let's proceed to how we computed the annual costs next.
Calculating Annual Costs

Continuing from our previous session, let’s explore how to derive annual costs. We combine operational costs with depreciation each year. How much did we set for the first year’s operational cost?
12 lakh?
Correct! So the total annual cost for the first year, including depreciation, is 11,20,000 plus 12 lakh. Can anyone calculate that?
That's 23,20,000 rupees!
Right again! Now, why do we care about annual costs?
To see if it’s worth keeping the machine or replacing it?
Exactly! Over time, comparing these costs helps us decide whether it’s economic to keep or replace the equipment based on performance.
Lastly, how do we find cumulative costs to understand our expense trend better?
Adding them up year after year?
Yes, that’s right! It's beneficial for decision-making in terms of financial planning.
Summarizing, we will look into how to evaluate the economic life of machinery next.

Now let’s discuss economic life. How do we define that term?
Is it the period during which the machine is most cost-effective?
Exactly! The goal is to maximize efficiency while minimizing costs. We establish economic life using average annual cumulative costs. How did we find the lowest cost?
By comparing the average yearly costs of both machines?
Correct! Doctor James Douglas mentions replacing machines when the current machine's cost exceeds the minimum average cost of the new machine.
And that’s why we calculate cumulative costs?
Exactly! It reinforces our decision-making process on replacing machinery effectively.
By evaluating calculated costs, we ensure we are not overspending on outdated machinery.
In summary today’s focus was on the concept of economic life and making informed decisions based on calculated costs.

As we wrap up, let’s look at guidelines for deciding when to replace old machines. Who remembers the replacement guideline from Dr. Douglas?
Replace when the estimated annual cost of the current machine is higher than the minimum average cost of the new machine?
Exactly! Great recall! How will we know if it’s time for a specific machine?
By comparing both annual costs for their respective machines?
Yes! You’ve got it! Comparing the actual costs helps ensure we invest our resources wisely.
So if our loader cost next year exceeds the proposed new loader's cost, we replace it?
Exactly! This analysis ensures an optimally functioning setup.
In summary, this session solidified how to determine optimal replacement periods for equipment.
Introduction & Overview
Read summaries of the section's main ideas at different levels of detail.
Quick Overview
Standard
The section elucidates how to calculate depreciation on a machine based on its book value and outlines how to determine annual costs including depreciation over multiple years. It highlights methods for estimating the economic life of machinery and deciding when to replace equipment.
Detailed
Depreciation Calculation
Depreciation serves as a vital accounting method of allocating the cost of a tangible asset over its useful life. In this section, we cover:
- Depreciation Calculation: The initial depreciation for the first year is computed as 0.4 times the book value of the machine. For instance, with a book value of 28,00,000 rupees, the depreciation for the first year (D1) amounts to 11,20,000 rupees.
- Book Value Adjustment: The concept of book value is crucial as it is adjusted after each year's depreciation. For example, at the end of the first year, the book value becomes 16,80,000 rupees after deducting the first year's depreciation.
- Continued Depreciation Calculation: The process is repeated in the next year (for year two) where depreciation (D2) is calculated based on the new book value at the end of the first year. As shown, for the second year, the depreciation is 6,72,000 rupees, leading to a new book value of 10,80,000 rupees.
- Annual Costs: The section further explains how annual costs can be derived from operational and maintenance costs alongside depreciation, suggesting significant yearly expenses must be assessed systematically.
- Cumulative Cost and Average Costs: The narrative includes how to determine cumulative costs and average annual cumulative costs across years. For example, the average annual cumulative cost over the first year is calculated and is used to compare with subsequent years.
- Decision-making for Replacement: The economic life of machinery is assessed over its operational years. The average annual cumulative costs of a proposed loader compared to an old loader help in determining when to replace the machines based on expense efficiency.
- Replacement Guidelines: Suggestions from Dr. James Douglas highlight that equipment should be replaced when the estimated annual cost of the current machine exceeds the minimum average cost of a proposed machine, ensuring optimal economic outlook.

You can calculate the cumulative cost, then find the average annual cumulative cost. It is nothing but your the cumulative cost divided by the cumulative usage of the machine. So, for the first year, Average annual cumulative cost, first year = 23,20,000/1 = 23,20,000 rupees.
Detailed Explanation
In this chunk, we talk about how to find the average annual cumulative cost, which gives insights into the equipment’s overall cost-effectiveness over time.
- Calculate Cumulative Cost: Start with the total annual cost calculated previously (23,20,000 rupees).
- Find the Average Annual Cumulative Cost: For the first year, this is simply the cumulative cost because there’s only one year of data:
Average Annual Cumulative Cost = Total Cumulative Cost / Number of Years = 23,20,000 / 1 = 23,20,000 rupees.
Examples & Analogies
This can be compared to tracking how much you spend yearly on a subscription, like a gym fee. The first year, if you pay 23,20,000 rupees, your average spending for that year is straightforwardly the same because you've only utilized the service for one year.
Key Concepts
-
Depreciation: A systematic reduction in asset value over time.
-
Book Value: The net value of an asset after depreciation.
-
Annual Costs: The total expense of operating an asset for a given year.
-
Economic Life: The period during which an equipment remains beneficial.
-
Replacement Decision: Guidelines for assessing the replacement of machinery.
Examples & Applications
Example of calculating first year depreciation: D1 = 0.4 × 28,00,000 = 11,20,000.
Book value calculation for the second year: 16,80,000 - 6,72,000 = 10,80,000.
