Uniform Series Capital Recovery Factor
🔒 Unlock Audio Lesson
Sign up and enroll to listen to this audio lesson
Today, we are discussing the Uniform Series Capital Recovery Factor. This factor helps convert our initial investment into an annualized cost. Does anyone know how it's calculated?
Is it that formula with the interest rate and lifespan?
Exactly! The formula is \( i \cdot \frac{(1+i)^n}{(1+i)^n-1} \). Here, \(i\) is the interest rate, and \(n\) is the number of years. Let's use an 8% interest over 12.5 years.
So what would that turn our cost into?
In this case, it gives us an annual cost of ₹37,41,844.41. It’s crucial for effective budgeting, right?
Yes, it helps in planning our finances better!
Great! Now remember this acronym, 'UCAC', for Uniform Cost Annual Calculation. It can help you remember how to use this method effectively.
To summarize, we learned that the UCAC allows us to derive annual costs from an initial investment using interest rates and time frames.
Annualized Salvage Value

Moving on, how do we convert the salvage value into an annualized cost?
Isn't that done using the sinking fund factor?
Absolutely! The formula here is \( \frac{i}{(1+i)^n-1} \). It helps us create an equivalent uniform cost from the salvage value.
How do we apply this?
For instance, if our salvage value is 20% of ₹2,89,00,000, then it becomes ₹57,80,000. After applying the factor, we can find it gives us an annualized salvage value of ₹2,85,968.88.
What do we do with those figures?
Excellent question! We can use these annual values to determine hourly depreciation rates, which is crucial for operational budgeting. Remember, 'SAV', standing for Salvage to Annualized Value.
To wrap up, we learned how to annualize a salvage value to better reflect its significance in total cost accounting.
Calculating Operating Costs
🔒 Unlock Audio Lesson

Now let's talk about the total operating costs, which incorporate both ownership and operational costs. Can anyone tell me how to calculate hourly depreciation?
Is it based on initial and salvage values?
Precisely! We subtract the annualized salvage from the annualized initial costs and divide it by the annual usage. So for our case, it's \( \frac{37,41,844.41 - 2,85,968.88}{1600} = ₹2,159.92/hr\).
And then we need to add that to other ownership costs, right?
Correct! Including insurance and taxes, we arrive at a total hourly ownership cost of ₹3063.05.
How do we estimate operational costs on top of that?
We need to look at consumables like fuel, FOG costs, and tire expenses. Understanding these granular costs allows for more accurate project budgeting.
What’s the final takeaway from today?
Understanding how to integrate all these factors into the total cost enables for better financial management in projects. Remember the acronym 'TOC' for Total Operating Costs!
Introduction & Overview

Quick Overview
Standard
In section 7.2, we explore the calculation of equivalent uniform annual costs for both initial investment and salvage value within equipment cost analysis. The section elaborates on effective methods such as the uniform series capital recovery factor and sinking fund factor for transitioning these values into operational costs.
Detailed
Recommended References
In this section, we delve into the process of calculating the equivalent uniform annual costs for both initial investment and salvage value in the context of equipment cost estimation. The initial cost is computed using the formula for the uniform series capital recovery factor, which translates the upfront investment into annual costs over its useful life (12.5 years at an 8% interest rate). This calculation leads to an annualized cost of ₹37,41,844.41.
Similarly, the salvage value, representing the expected resale value at the end of the machine's life, is converted into a uniform annual cost through the sinking fund factor, culminating in an annualized salvage value of ₹2,85,968.88. The difference between the annualized initial cost and salvage value facilitates the calculation of hourly depreciation, resulting in a value of ₹2159.92 per hour. Further, we explore ownership costs, including insurance and taxes, which are derived as percentages of the adjusted initial cost, culminating in a complete hourly ownership cost of ₹3063.05. Finally, the section highlights various consumable costs, such as fuel and maintenance, emphasizing the overall operational cost estimation totalling ₹5759.20 per hour, thus integrating both ownership and operational expenses.

So these are the references which I have used for this lecture preparation. As I told you there are so many preparation handbooks. One such equipment handbook I have cited here is by US Army Corps of Engineers.
Detailed Explanation
In this section, the lecturer explains that various preparation handbooks are available for reference. These handbooks act as guides for understanding equipment-related logistics, cost estimations, and operational guidelines. The US Army Corps of Engineers is mentioned as a specific, reliable source where valuable information can be found.
Examples & Analogies
Think of equipment handbooks like cookbooks for engineers. Just as cookbooks provide recipes and tips for making great meals, these handbooks offer essential instructions and guidelines for handling and estimating the costs associated with various types of equipment.

You can try to go through all these handbooks so that you can get through on the information on the various factors which we have mention the fuel consumption factor or the FOG, labor adjustment factors.
Detailed Explanation
The lecturer encourages students to refer to these handbooks to deepen their understanding of various factors influencing equipment operation. Important terms like fuel consumption factor and FOG (Filter, Oil, Grease) refer to essential elements that affect the maintenance costs of equipment. By exploring these handbooks, students can learn to make more accurate estimates, enhancing both their theoretical and practical knowledge.
Examples & Analogies
Imagine you're trying to fix your car. Consulting a repair manual not only helps you fix the immediate issue but also informs you about ongoing maintenance, such as when to change the oil or replace the air filter. Similarly, equipment handbooks give engineers the insights needed for operational efficiency.
