Understanding Initial Costs
Unlock Audio Lesson
Today, we’ll discuss how we convert initial costs into equivalent uniform annual costs. Can anyone tell me why it’s important to annualize costs?
I think it helps in comparing costs on an annual basis!
Exactly! By annualizing costs, we can assess costs over the useful life of an asset. The formula we use includes the interest rate and the asset's lifespan. Remember the acronym EAC for Equivalent Annual Cost.
What does the formula look like, Teacher?
Good question! The formula is \(EAC = \frac{I \cdot (i(1+i)^n)}{(1+i)^n - 1}\). Here, \(I\) is the initial cost, \(i\) is the interest rate, and \(n\) is the lifespan. Can anyone apply this with an example?
If the initial cost is ₹2,89,00,000, what's an example annual cost if the interest rate is 8% over 12.5 years?
That's right! When you calculate that, the annualized cost would come out to be ₹37,41,844.41. Remember, calculating EAC helps in budgeting!
Calculating Salvage Value
Unlock Audio Lesson
Let’s now shift our focus to salvage values. How do we convert future salvage values into annual costs?
Is it the same as converting initial costs?
Partially correct! The method is different. You will use the sinking fund factor formula for this. It goes as follows: \(EAC_{SV} = \frac{SV \cdot i}{(1+i)^n - 1}\). Can anyone explain what each variable stands for?
SV is the salvage value, i is the interest, and n is the useful life of the machine, right?
Perfect! For example, if the salvage value is 20% of that initial cost, and you have the same interest and lifespan, the salvage value comes to about ₹2,85,968.88 yearly.
Evaluating Total Ownership Cost
Unlock Audio Lesson
Now that we understand both initial and salvage value costs, let’s see how ownership costs are calculated.
Does that include insurance and taxes?
Exactly! You will assess the depreciation cost, insurance cost, and tax cost as a percentage of initial costs. Can anyone tell me a typical percentage for insurance?
Two percent of the initial cost, right?
Yes! By calculating these components, you can sum them up to find your total cost per hour. All these values allow a comprehensive assessment of ownership and operational costs.
Understanding Hourly Depreciation
Unlock Audio Lesson
Next, let’s focus on hourly depreciation. How do we find that once we have the annualized costs?
I think we subtract the salvage value from the annualized cost and then divide by the hours of operation?
Exactly! So if we have ₹37,41,844.41 as the annual cost and ₹2,85,968.88 as salvage, and let’s say the machine operates 1600 hours a year, what’s the hourly depreciation?
It would be ₹2,159.92 per hour.
Well done! Understanding hourly depreciation is crucial for making informed financial decisions about asset management.
Introduction & Overview

Quick Overview
Standard
The section elaborates on the impact of the salvage value on the annualized cost of an asset. It explains how to calculate the equivalent uniform annual cost of both the initial and salvage values based on the interest rate and useful life of the asset.
Detailed
Equivalent Uniform Annual Cost of Salvage Value
This section examines the calculation of equivalent uniform annual costs associated with salvage values, integral to evaluating the financial feasibility of assets. The formula for converting initial costs to an annualized format using a capital recovery factor is introduced. By understanding the formula:
$$EAC = \frac{I \cdot (i(1+i)^n)}{(1+i)^n - 1}$$
where:
- EAC: Equivalent Annual Cost
- I: Initial cost
- i: Interest rate
- n: Useful life of the asset
the initial investment cost can be converted to a uniform annual cost. Here, an illustration involves an initial cost of ₹2,89,00,000 and an annualized initial cost of ₹37,41,844.41. Next, the discussion transitions to salvage values, emphasizing the need to convert future salvage values into equivalent annual costs using the uniform series sinking fund factor formula:
$$EAC_{SV} = \frac{SV \cdot i}{(1+i)^n - 1}$$
Example calculations yield an annualized salvage value of ₹2,85,968.88. The text covers the assessment of depreciation costs, insurance, taxes, and overall ownership costs. Finally, it integrates specific operational costs like fuel consumption and the distinct cost contributions of multiple factors towards total equipment cost.

The equivalent uniform annual cost of initial cost = Initial cost × [ (1+i)^n ] / [ (1+i)^n - 1 ]
Initial Cost = ₹ 2,89,00,000
Interest Rate = 8%
Product Useful Life (n) = 12.5 years
= ₹ 37,41,844.41/year
Detailed Explanation
To convert the initial cost of the equipment into an annual figure, we use a formula that incorporates the initial investment amount, the interest rate, and the useful life of the product. Here, the initial cost is ₹ 2,89,00,000, we apply the interest rate of 8% over 12.5 years. Using the capital recovery factor from the formula provided, we arrive at an equivalent uniform annual cost of ₹ 37,41,844.41. This means that spreading out the cost of the equipment over its useful life gives an annualized cost that can better assist in budgeting and financial planning.
Examples & Analogies
Think of this process like taking out a loan to buy a car. Instead of paying all at once, you pay monthly. The equivalent uniform annual cost is like determining how much you would pay each year for your car over its usable life, including interest, making it easier to understand the annual financial commitment.

The equivalent uniform annual cost of salvage value = Salvage value × [ i / ((1+i)^n - 1) ]
Salvage Value = 20% of Initial Cost = ₹ 57,80,000
= ₹ 2,85,968.88/year
Detailed Explanation
The salvage value represents the expected value of an asset at the end of its useful life. To convert this future value into an annual cost, a different formula is used which discounts the salvage value into annual terms based on its lifespan and the interest rate. Here, we find that the salvage value is ₹ 57,80,000, leading to an annual cost of ₹ 2,85,968.88. This figure represents the annual cost refining our overall investment in the equipment.
Examples & Analogies
Imagine if you plan to sell your car for a certain amount after five years. Just like estimating how much you might earn back, the equivalent annual cost of salvage value helps you recognize how much of that value should be accounted for each year, aimed at helping you make informed financial decisions.
Hourly Depreciation Calculation

Hourly Depreciation = (Annualized Initial Cost - Annualized Salvage Value) / Annual Use of Machine in Hours
Annual Use = 1600 hours
= ₹ 2159.92/hour
Detailed Explanation
Once we have the annualized costs for both initial cost and salvage value, we can determine the hourly depreciation. This takes into account the difference between these costs and divides it by how many hours the machine is estimated to be used annually. Hence, by subtracting the annualized salvage value from the annualized initial cost, and dividing by 1600 working hours, we calculate that the hourly depreciation cost amounts to ₹ 2159.92. It gives us insights into how much value the machine loses for each hour it operates.
Examples & Analogies
Consider it like a smartphone you bought for ₹ 50,000, which you know will be worth around ₹ 10,000 after 5 years. If you use it daily, hourly depreciation helps you see how much value the phone loses each hour of use, translating that into a real financial answer each time you replace the device.
Ownership Cost Breakdown

Total hourly ownership cost = Hourly Depreciation + Hourly Insurance + Hourly Taxes
Total Hourly Ownership Cost = ₹ 3063.05/hr
Where:
Hourly Insurance = ₹ 361.25/hr
Hourly Taxes = ₹ 541.88/hr
Detailed Explanation
To understand the total cost of owning the equipment per hour, we sum the individual components like the calculated hourly depreciation, insurance, and taxes related to the ownership. Each of these costs gives a comprehensive view of ongoing expenses associated with the asset. Following the calculation, we ascertain that the total hourly ownership cost is ₹ 3063.05. This enables better budgeting and forecasting for operational costs.
Examples & Analogies
Think of owning a rental property. Besides just the mortgage, there are property taxes and insurance that contribute to your monthly costs. Similarly, to grasp the actual cost of running equipment, it’s important to include all ownership-related expenses in a total calculated cost.
