Now, let's discuss the factors influencing replacement costs. What are some you can think of?
I remember something about maintenance costs!
Yes! Maintenance and repair costs rise as machines age. What else?
Obsolescence costs due to newer technology!
Good! And let's not forget about inflation and downtime costs. So, can anyone explain why estimating these is important?
To find the best time to replace our machinery and minimize losses?
Exactly! Tracking these costs helps in making informed replacement decisions. Utilize the mnemonic **M.O.O.D**: *Maintenance, Obsolescence, Operating costs, and Downtime*!

Let’s work through the example of estimating replacement costs. What’s the purchase price of the shovel?
35,00,000 rupees!
Correct! And if inflation increases costs by 2,10,000 each year, what are the replacement costs for the first year?
It would be 37,10,000 rupees after one year!
Well done! Each year's increase is important in our calculations. Keep in mind, **I CAN**: *Inflation Creates Added Needs* when assessing long-term costs. How can we summarize these calculations?
Each year, we need to recalculate both the salvage value and the increased costs to see the net loss or gain!
Yes! You have captured the essence of calculating replacement costs!
Understanding Depreciation

Next, we need to calculate how depreciation affects our costs. Does anyone remember the formula?
It’s two times the straight-line rate multiplied by the book value!
Right! How about we work through the first year of depreciation together?
Sure! For the first year, it would be 2 divided by 8 multiplied by 35,00,000!
Excellent! And what’s our result?
8,75,000 rupees for the first year!
Correct! This is significant in determining the book value. Remember: **B.A.S.I.C**: *Book value Affects Salvage In Calculations*!
Introduction & Overview
Read summaries of the section's main ideas at different levels of detail.
Quick Overview
Standard
The section elaborates on the concept of economic life, illustrating how costs associated with machinery increase after a certain period. Using an example of a track-mounted front shovel, it highlights the importance of considering depreciation, inflation, maintenance, downtime, and obsolescence when estimating replacement costs.
Detailed
Replacement Cost Estimates
This section focuses on understanding the economic life of machinery, defined as the period during which the cost of holding a machine is minimized. Beyond this economic life, costs can increase due to various factors, including:
- Maintenance and repair costs
- Downtime costs (loss incurred when machinery is not operational)
- Obsolescence costs (due to wear and technological advancements)
To illustrate replacement cost estimates, an example using a track-mounted front shovel is analyzed, where key aspects such as depreciation using the double declining balance method and inflation leading to increased machinery costs are discussed. The economic life of the machinery and its various cost elements, particularly in terms of annual increases, maintenance, and potential losses due to inefficiency, are critically examined and calculated. This highlights that by accurately estimating these costs, one can determine the optimal replacement time for machinery to avoid accruing excessive losses.

Chapter Content
Economic life refers to the period during which the cost of holding the machine is minimized. Beyond this period, costs associated with the machine tend to rise due to increasing operational costs (repairs and maintenance) or downtime costs.
Detailed Explanation
The concept of economic life highlights the timeframe in which an asset, like a machine, is most cost-effective to operate. After this period, various costs associated with maintaining the machine can escalate. For instance, as the machine ages, it may require more frequent repairs, resulting in higher operational expenses, and it could also face longer periods of inactivity (downtime) when it isn't available for work.
Examples & Analogies
Consider a car: when it is new, it runs smoothly, and the maintenance costs are low. However, as it ages, it might need more repairs and could spend more time in the shop, leading to increased costs and downtime. This parallels the economic life of machinery in a factory setting.

For example, consider a track-mounted front shovel with a purchase price of 35,00,000 expected to last 8 years. Assuming a salvage value of 7,00,000 and an inflation-driven cost increase of 2,10,000 per year.
Detailed Explanation
In this example, we are estimating the economic life of a specific machine. The initial cost is recorded, and the expected lifespan and residual value upon sale after 8 years are noted. The inflation factor increases the cost of replacement yearly, emphasizing the importance of keeping track of these financial changes when planning for machine replacement.
Examples & Analogies
Imagine planning to upgrade your mobile phone. You know how much it costs currently, how long you expect to use it before you replace it, and how the price may rise over time due to new models being introduced – this works similarly for machinery.
Analyzing Replacement Costs

Chapter Content
Annual costs to consider in the replacement analysis include maintenance and repair costs, downtime costs, and the obsolescence cost which increases as the machine ages.
Detailed Explanation
When analyzing replacement costs, multiple factors must be considered. Maintenance and repair costs generally increase as the machine ages. Moreover, downtime costs accumulate when the machine is not operating, either due to repairs or breakdowns. Obsolescence costs represent the lost value as newer, more efficient technologies become available, making the older models less desirable.
Examples & Analogies
Think about upgrading your computer. As it ages, you may need to spend more on repairs, it may run slower affecting your work (downtime), and newer models become available with better specifications making your old one feel obsolete.
Depreciation Calculation

Chapter Content
The depreciation follows a double declining balance method. For the first year, the depreciation is calculated as 2/n times the book value from the previous year.
Detailed Explanation
Depreciation is the reduction in value of a machine over time. In the double declining balance method, the depreciation is calculated at a higher rate initially, which reduces over time. For example, if the initial cost of the machine is 35,00,000, the first-year depreciation would be a calculated value that significantly reduces the book value for subsequent calculations.
Examples & Analogies
This is similar to how some items lose value quickly after purchase, like cars. They depreciate primarily in the first few years, drastically lowering their resale value.
Investment Costs

Chapter Content
The investment cost includes expenses such as interest, insurance, and taxes, calculated as a percentage of the machine's book value.
Detailed Explanation
Investment costs are ongoing expenses necessary to maintain ownership of the machine. These can include interest payments if the machine was financed, insurance costs, and taxes. This section highlights how these costs accumulate over time, reflecting the true cost of ownership. In the example, an investment cost of 15% of the book value is given for every year.
Examples & Analogies
Imagine renting an apartment. The rent is just one part of the total cost; there are also utilities, insurance, and maintenance fees. Together, these form the complete cost of living there.
