Understanding Ownership and Operating Costs
Unlock Audio Lesson
Today, we're going to explore ownership and operating costs when using heavy equipment. Can anyone tell me what they think ownership costs include?
I think it includes the purchase price of the equipment and any depreciation over time.
Exactly! Ownership costs include not just the purchase price but also depreciation, interest, insurance, and taxes. Now, who can tell me what operating costs might involve?
Operating costs would include things like fuel and wages for the operator, right?
Yes! Operating costs typically include fuel, wages, maintenance costs, and anything related to the operation of the equipment. It's important to calculate both to understand the total cost effectively. Remember the acronym FOG, referring to Filter, Oil, and Grease costs, which are components of operating costs.
Got it! FOG stands for Filter, Oil, and Grease.
Great job! So now, let's look at how we can estimate these costs practically.
Estimating Costs Using Caterpillar Method
Unlock Audio Lesson
Now that we have a grasp on the definitions, let's use the Caterpillar method to estimate the costs. Can anyone recall how we calculate depreciation?
Depreciation is calculated by taking the initial price minus salvage value, then dividing by the useful life of the machine.
Right! For example, let's say our dump truck has an initial cost of 3 crores and no salvage value. If its useful life is 12.5 years, what would the annual depreciation be?
It would be ₹23,12,000 per year.
Exactly! And then we can divide this by the number of hours it operates to find the hourly depreciation. Does anyone remember what that would be?
That would be about ₹1,445 per hour.
Correct! This is how we begin structuring the ownership costs using the Caterpillar method.
Calculating Operating Costs
Unlock Audio Lesson
Moving on, let's calculate our operating costs for the dump truck. What factors do we consider for that?
We need to factor in the fuel consumption rate and the labor adjustment factors.
Exactly! For the fuel cost, if the fuel consumption factor is 0.09 liters per hour per horsepower and our truck is 250 horsepower, with a fuel cost of ₹65 per liter, how do we calculate the hourly fuel cost?
It's ₹1462.50 per hour!
Very well! Now, if we also factor in the FOG costs based on the fuel cost, what do we get?
If we multiply the FOG factor of 0.119 by ₹1462.50 and by the labor adjustment factor, we get ₹139.23.
Great job! Let’s add all our operating costs together and see the total.
Peurifoy Method for Cost Estimation
Unlock Audio Lesson
Now, let's discuss the Peurifoy method, which is a more detailed approach to estimating costs. What is different about this method?
It considers the timing of cash flows and uses a time value method.
Correct! It also includes salvage values and typically results in more accurate cost estimates. Can someone give me the formula for estimating the average annual investment?
It’s the purchase price minus the tire cost divided by two times the useful life.
Excellent! This approach ultimately helps in understanding the real impact of using equipment over time.
Introduction & Overview

Quick Overview
Standard
In this section, the process of estimating equipment costs for a dump truck through two methods—Caterpillar and Peurifoy—is elucidated. Key concepts such as ownership costs, operating costs, and specific components like tire costs, fuel consumption, and FOG are detailed with mathematical formulas and example calculations.
Detailed
Detailed Summary
This section provides a comprehensive guide on estimating the costs associated with the usage of heavy equipment, particularly focusing on Filter, Oil, Grease (FOG) components. The section begins with an overview of how to calculate total costs by incorporating both ownership and operating costs, adhering to Peurifoy's guidelines.
Key Points Covered:
- Ownership and Operating Costs: The foundational principle is that total costs (ownership + operating) must reflect accurate usage and costs associated with operating heavy equipment, like a dump truck.
- Examples and Calculations: Through a practical example of a dump truck with detailed specifications and costs (like purchase price, hourly usage, tire costs, etc.), various calculations—such as depreciation, interest, insurance, taxes, and operating costs—are performed.
- Caterpillar Method vs. Peurifoy Method: The section explores two approaches to cost estimation:
- Caterpillar Method: Focuses on straightforward calculations using defined formulas and estimates.
- Peurifoy Method: More comprehensive, accounting for salvage values and detailed operating conditions.
- FOG Costs: Specific emphasis is laid on filtering, oil, and grease costs, derived from fuel consumption and adjusted for operational conditions.

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 a piece of equipment like a dump truck, you need to calculate three main components: ownership costs, operating costs, and wages of the personnel operating the equipment. The total cost is found by adding these components according to the Peurifoy guidelines, which provide a structured approach to cost estimation in construction.
Examples & Analogies
Think of estimating costs like planning a budget for a vacation. Just as you would tally up travel costs, lodging, food, and activities to create a total expense, in equipment cost estimation, you gather all costs related to ownership, operation, and labor to understand the full financial commitment.
Understanding Off-Highway Trucks

The initial cost is given so it was purchased with the deliver price of 3 crores. [...] It is not permitted on the public highways.
Detailed Explanation
An off-highway truck is specifically designed for tasks on construction or mining sites rather than for public roads. The truck mentioned in this estimation has an initial purchase price of 3 crores, which is indicative of its advanced features and capabilities. Companies often invest significantly in these types of specialized equipment because they provide substantial efficiency on the job.
Examples & Analogies
Consider an off-highway truck like a specialized sports car; while it may be expensive, it's designed to perform in specific conditions where standard vehicles cannot compete, such as rugged terrain found on job sites.
Calculating Depreciation

So under the ownership cost let us calculate the depreciation first.
Detailed Explanation
Depreciation is the reduction in the value of the truck over time due to wear and tear. To calculate depreciation for the truck, you subtract the tire cost from the initial price, and since the salvage value is zero, divide this amount by the useful life of the machine. This allows companies to spread the cost of the asset over its useful lifespan, providing a more accurate picture of its financial impact.
Examples & Analogies
You can think of depreciation like losing value on a new car: as you drive it and time goes on, its market value decreases. Just as a car loses value each year, equipment like a dump truck also depreciates in value, which businesses need to account for in their financial statements.

Now let us move on to the operating cost estimation...
Detailed Explanation
Operating costs include fuel, maintenance, and other parts of running the equipment. For example, the fuel consumption is calculated based on several factors including the truck's horsepower and fuel price. Accurate estimation requires the integration of various data points to get a holistic view of operation costs.
Examples & Analogies
This situation is comparable to maintaining a household budget where you track expenses such as groceries, utilities, and maintenance for appliances. Just as these recurring costs might change based on consumption, the operating costs for equipment vary depending on usage, fuel prices, and maintenance needs.
Final Cost Calculation

Total hourly operating cost = ₹ 3209.29 per hour.
Detailed Explanation
To determine the total equipment cost, you add the total hourly ownership cost to the operator's wages. In this estimation, you've calculated the operating cost, and after accounting for labor, you arrive at a comprehensive hourly cost for the operation of the dump truck.
Examples & Analogies
This is like adding together all your monthly bills—rent, utilities, groceries—to find out how much income you need each month to maintain your lifestyle. In equipment operations, doing the same with all costs ensures that the business can sustain its equipment operation financially.
