Today, we will discuss the economic life of a machine. Can anyone explain what economic life means?
Is it about how long the machine is useful for us without being too costly?
Exactly! Economic life refers to the period during which the costs of operating the machine are minimized. Beyond this time, costs generally increase.
So, what happens if we keep the machine too long?
Great question! Keeping the machine longer can lead to increased maintenance costs, downtime, and obsolescence. Remember the acronym MOD: Maintenance, Operating cost, Downtime.
Got it! MOD helps me remember the costs to consider.
Exactly! So, why is it important to understand economic life?
To decide when to replace it and avoid unnecessary costs!
Right! Let’s move on to see how we calculate depreciation using the double declining balance method.
Now we will tackle depreciation. Can anyone tell me what depreciation is?
Is it how much value the machine loses each year?
Exactly! We use the double declining balance method, which accelerates the depreciation in the early years. The formula is 2/n × Book Value of the previous year. Can anyone apply this to our case?
So in the first year, it would be 2/8 × 35,00,000 which equals ₹8,75,000!
Correct! What’s the new book value?
It would be ₹35,00,000 minus ₹8,75,000, which is ₹26,25,000!
Excellent! You would repeat this process each year. Let’s ensure we understand how this affects our overall costs with inflation and salvage value.
We must also consider other costs like maintenance, repair, downtime, and obsolescence. Can anyone explain downtime?
That’s when the machine isn’t available for use, right?
Exactly! Downtime can lead to additional costs. How do we measure the impact of downtime on our operation?
By calculating the downtime costs based on our equipment cost!
Right! And as machinery ages, costs like maintenance and obsolescence will increase. Remember, maintenance affects CAPEX — Capital Expenditure.
Can we calculate how much extra we lose in productivity if downtime increases?
Yes! Always try to connect the dots between maintenance, downtime, and productivity. Let's ensure we apply this understanding when we finalize replacement strategies.
The time frame in which equipment holds the least cost of ownership and operation.
Double declining balance is an acceleration method leading to more rapid depreciation upfront compared to the straight-line method.
Costs incurred due to non-operational periods, impacting productivity and revenue.
The process of becoming outdated, which can increase replacement costs over time.
To save your cash, replace don't wait, keep your machines in their prime state.
A carpenter clings to his old, rusty saw, believing it still cuts as well. As it dulls, he can't finish jobs on time. Needing new tools, he learns to replace them before they become obsolete.
Remember the costs with the phrase MOD: Maintenance, Operating costs, Downtime.

The period during which a machine operates with minimal costs.
The reduction in value of an asset over time, used for accounting purposes.
An accelerated depreciation method that doubles the straight-line rate.
The period during which a machine is not operational and cannot perform productive work.
The process of becoming outdated, particularly due to advances in technology.
This section explains the concept of economic life and depreciation calculation, focusing on the costs associated with maintaining and replacing machinery.
The section delves into depreciation calculation and how it influences the decision-making process for replacing machinery. It covers the economic life definition, the model for calculating depreciation using the double declining balance method, and the factors contributing to costs associated with machinery over time.
This section discusses the economic life of machinery — defined as the period in which the cost of ownership is minimized. Beyond this economic life, costs typically arise in the form of increased maintenance, repair, and obsolescence. It emphasizes the necessity of timely replacement to avoid losses.
Key calculations are presented through a practical example — estimating the economic life of a machine, specifically a track-mounted front shovel purchased for ₹35,00,000 and expected to last 8 years with a salvage value of ₹7,00,000. The section illustrates how to employ the double declining balance method for depreciation, detailing the calculations year by year.
Additionally, factors such as inflation, operational costs, and maintenance costs are outlined. The relationship between downtime and increased costs is analyzed, noting how obsolescence due to technological advancements impacts financial planning for equipment replacement. Through cumulative calculations and practical exercises, students learn to assess total cost implications annually for decision-making. This thorough exploration of depreciation calculation serves as a critical foundation for understanding machinery cost analysis and investment strategies.
