Today, we will explore the key components of repair cost calculations. First, can anyone tell me what ownership costs are?
Are those the costs we incur to own and maintain the equipment?
Exactly! Ownership costs include depreciation, insurance, taxes, and financial charges. What about operating costs?
Are those the daily expenses while using the equipment, like fuel and wages?
Right again! Operating costs can significantly affect our budget. Remember the acronym 'DO-WIF' to keep track of these: D for Depreciation, O for Ownership, W for Wages, I for Insurance, and F for Fuel. Now, let’s move on to how these costs are calculated.
Depreciation and its Calculation

Depreciation is a critical part of ownership costs. Can anyone tell me how we calculate it?
Is it the initial cost minus salvage value over useful life?
Great! Yes, the formula is: (Initial Price - Salvage Value) / Useful Life. What is the useful life of our dump truck in this example?
12.5 years, right?
That's correct! With that, we can estimate an annual depreciation. Can anyone remind me of our truck's initial cost?
It was 3 crores.
Perfect! Now let's calculate the depreciation using these numbers.

Next, we need to calculate the operating costs. What factors should we consider?
Fuel consumption and repair costs?
Yes! And we also need to factor in industry-specific details, like the fuel consumption rate and local price. Can anyone calculate the fuel cost for our dump truck?
It's 0.09 liters per horsepower multiplied by the power rating, plus the cost of fuel.
Exactly! Now let's perform this calculation together.
Comparing Calculation Methods

We’ve covered the Caterpillar method. What is the Peurifoy approach teaches us about repair cost calculation?
It factors in salvage value differently and uses a time value method!
That's right! The Peurifoy approach also emphasizes accurate timing of cash flows. Why do you think this is important?
Because the value of money changes over time.
Exactly! This approach helps ensure we account for that. Now let’s summarize the key takeaways.
Introduction & Overview

Quick Overview
Standard
The section introduces essential concepts of repair cost calculation, emphasizing ownership and operating costs, along with practical examples like estimating the cost of an off-highway dump truck. It incorporates different calculation methods and all relevant factors including depreciation and repair factors.
Detailed
In chapter 3.4, we dive deep into calculating repair costs, specifically for off-highway vehicles such as dump trucks. The focus is on two calculation methods: the Caterpillar method and the Peurifoy approach. We start by breaking down ownership costs, which include depreciation calculated via the straight-line method, and operating costs like fuel, wages, and maintenance. Various factors including interest rates, insurance, tax, and usage hours are incorporated into the calculations, providing a comprehensive understanding. The section concludes with practical examples that help in understanding the estimation of repair costs effectively.

So just add up everything the ownership cost all the operating cost and operating wages also you
will get the total ownership and the operating cost following the Peurifoy guidelines.
Detailed Explanation
To estimate the total cost of operating equipment, you need to combine several expenses, including ownership costs (like depreciation), operating costs (fuel, maintenance, etc.), and the wages of operators. This approach adheres to the Peurifoy guidelines and provides a comprehensive view of what it costs to use a piece of equipment.
Examples & Analogies
Think of it as running a small business. You would consider all your expenses: rent (ownership cost), utilities (operating cost), and employee salaries (wages). Just like you total all these expenses to know how much money you need each month, you do the same for equipment usage.

This truck is not permitted on the public highways. It is an; heavy equipment high end equipment you can see that these trucks will be operated only in the project sites.
Detailed Explanation
Off-highway trucks are specialized vehicles that cannot be driven on public roads. Used primarily on construction or mining sites, these trucks are designed for heavy-duty tasks and feature enhanced capabilities. Understanding their operations is crucial for accurate cost estimation since they generally have unique pricing and maintenance needs compared to regular trucks.
Examples & Analogies
Imagine construction sites where only specific heavy machinery can operate, similar to how certain sports facilities have equipment suited only for that sport. Just like a basketball court isn't suitable for soccer, off-highway trucks aren't allowed on regular roads.

The initial cost is given so it was purchased with the delivery price of 3 crores. The tire cost of this machine is 11 lakhs.
Detailed Explanation
To calculate ownership costs, start with the initial purchase price of the equipment, which is 3 crores in this case. Then subtract the tire cost (11 lakhs) to focus on the other cost components related to the truck. This forms the basis for further calculations related to depreciation and operating costs.
Examples & Analogies
It's like buying a car: the purchase price includes the car's cost, and if you consider its maintenance, you might separate out the cost for tires or special features to understand how much you shell out after the initial payment.

The other associated cost are the interest rate which is nothing but 8% insurance 2% and taxes 3%.
Detailed Explanation
Ownership costs also include various financial factors such as interest on loans (8%), insurance (2%), and taxes (3%). These costs contribute to the overall expense of maintaining the equipment and must be factored into total cost calculations to avoid unexpected expenses.
Examples & Analogies
This can be compared to owning a house where, apart from the mortgage (interest), you also pay for property insurance and taxes. Just like you wouldn't solely consider your mortgage payment, you have to include these additional costs for a clear view of your total investment.
Estimating Depreciation

So the depreciation is done to 0 value you can say that it is nothing but initial price minus tire cost minus salvage value.
Detailed Explanation
Depreciation is a way to account for the loss of value of an asset over time. In this case, it's calculated by taking the initial price, subtracting the cost of tires and assuming a salvage value of zero. This helps determine how much value the equipment loses each year, which must be included in the overall operating costs.
Examples & Analogies
Imagine you buy a brand new smartphone. Over time, it loses value due to wear and tear and newer models being released. Just like tracking that depreciation can help you decide when to sell or upgrade, it's the same for equipment.

P(n+1)+S(n−1) / 2n.
Detailed Explanation
To find the average annual investment, you can use a formula that incorporates the purchase price without the tire cost and divides it by the number of years you expect to use the equipment. This average cost per year helps in budgeting and planning for future expenses.
Examples & Analogies
Think of it like budgeting for a car—you would estimate how much money you put aside each year for repairs and operating costs, and this provides a clearer picture for your total expenditures over time.

The hourly equipment fuel cost as rupees 1462.5... Add everything, you will get the total operating cost as rupees 3209.29 per hour.
Detailed Explanation
Operating costs involve calculating various expenses like fuel consumption, maintenance supplies (such as oil and grease), tire costs, and repair costs. Each of these components contributes to the overall operating expense. By adding these figures together, you derive a total cost per hour for running the equipment.
Examples & Analogies
It's like running a household: you budget for groceries, utilities, and maintenance. Each spending category contributes to your overall monthly expenses, which is necessary to understand how much money you need each month.
