Today, we'll explore how to calculate depreciation. Let's say we have a machine valued at 28 lakh. What do you think we'll need to do to find the first year's depreciation?
We need to multiply the depreciation rate by the book value, right?
Exactly! The formula is D = rate × book value. If the rate is 0.4, the depreciation would be 0.4 × 28,00,000.
So, that's 11,20,000 rupees for the first year?
Great! And after we calculate the first year's depreciation, how do we find the book value for the next year?
By subtracting the depreciation from the purchase price, right?
Correct! So, the book value at the end of the first year is 28 lakh minus 11,20,000, which is 16,80,000.
What happens next for the second year?
We repeat the calculation using the new book value. Now let’s summarize what we learned today about depreciation.
Moving on to annual costs, besides depreciation, we must consider operating costs. How do we compute the annual cost for the first year?
By adding the operating cost to the depreciation?
Exactly! If our operating cost is 12 lakh and our depreciation is 11,20,000, what’s the total for the first year?
That would be 23,20,000 rupees.
Right! And for each subsequent year, we continue this method. Now, what can we infer from these cumulative costs?
We can figure out the average cost to help decide about replacement time.
Correct! It's all about evaluating cost-efficiency over the machine's lifespan.
Now that we’ve calculated costs, how do we determine economic life?
I think it's when the average cumulative cost starts increasing again after a drop?
Exactly! As costs initially drop, we look for the year where they hit minimum and begin to rise. Remember Dr. Douglas's method for replacement.
Is that when the current loader’s annual costs exceed the proposed machine’s average cumulative cost?
Yes, very well summarized! This comparison ensures that we only keep machinery that is cost-effective.
What if we consider profits too?
Perfect question! We eventually want to maximize profit too. So let’s explore that next.
The reduction in value due to use over time, crucial in assessing costs.
The total expense incurred in operating equipment, combining operating costs and depreciation.
The period when a machine is economically viable, suggested using both minimum cost and maximum profit methods.
A calculated choice made when it's financially better to replace a machine rather than maintain it.
If a machine has a purchase price of 28 lakh and a depreciation rate of 40%, its first-year depreciation is 11,20,000, giving a book value of 16,80,000 at the end of the year.
When the minimum average annual cumulative cost of a proposed loader is less than the annual cost of the old loader for the next year, replacement is financially justified.
When assets start to age, and costs they start to rise, keep an eye on depreciation; it's wise to recognize!
Imagine a machine named Max; it worked tirelessly for 10 years but started costing more to maintain than to replace. The learning? Always calculate and know when to let go!
The acronym 'DEAL' can help remember: D for Depreciation, E for Expenses, A for Annual Costs, and L for Lifecycle.
C.E.R.T. for deciding to replace: Cumulative costs, Economic life, Replacement decision, Total operating costs.

This section explores calculating depreciation and economic life based on profit and cost analysis for machinery.
This section delves into methods of assessing the economic life of equipment, focusing on calculating depreciation, annual costs, and the comparative analysis of current and proposed loaders using both minimum cost and maximum profit methods.
This section discusses the methods of calculating the economic life of machinery based on profit and cost analysis. It elaborates on the depreciation calculations for a given machine and how these adjustments affect the annual costs over the machine's life. Initially, the formula for depreciation is introduced, with examples showing how book value changes over the years. The process of calculating annual costs, including operating and maintenance costs, is demonstrated.
Key concepts include:
This section culminates in a thorough understanding of how depreciation affects economic life, the critical point for replacement decisions, and methods to analyze the profitability of machinery over its operational lifespan.
