Introduction to Fuel Cost Calculation
Unlock Audio Lesson
Today, we're going to focus on calculating fuel costs as part of total ownership and operating costs for equipment. Can anyone tell me what ownership costs typically include?
Does that include purchase price, taxes, and insurance?
Exactly! Ownership costs can be broken down into various elements like initial purchase price, depreciation, insurance, and financing costs. Now, what do you think operating costs encompass?
I think operating costs are things like fuel, maintenance, and labor.
Right again! Operating costs are an ongoing expense resulting from using the equipment. Let's move to an example to see how we can estimate these costs.
Estimating the Initial Cost of Equipment
Unlock Audio Lesson
For our example, we have a dump truck with an initial purchase price of 3 crores. But how do we account for the tires? What might we want to subtract?
We subtract the tire cost since it's treated separately?
Exactly! The total initial cost used for depreciation calculation is 3 crores minus the tire cost. So what would the depreciation be if we presume zero salvage value?
We would use the formula for straight-line depreciation over the machine's useful life.
Correct! And for this truck, what is its estimated useful life based on its annual usage?
It’s 12.5 years based on 20,000 total hours divided by 1,600 hours per year.
Great job! Understanding useful life is crucial for accurately calculating the depreciation.
Calculating Operating Costs
Unlock Audio Lesson
Next, let’s focus on operating costs, specifically the fuel cost for our dump truck. Can anyone provide the formula for calculating fuel costs?
Is it related to fuel consumption factor times horsepower times fuel price?
Exactly! In our case, we have a consumption rate of 0.09 liters per hour per horsepower multiplied by the truck's 250 horsepower and the local fuel price of 65 rupees per liter. What does that yield for hourly equipment fuel cost?
₹1462.50 per hour!
Spot on! Now let’s look at additional operating costs like tire costs. How do we estimate that?
We take the tire cost divided by its lifespan in hours, right?
Correct! That way, we allocate the cost appropriately based on tire usage.
Total Cost Estimation and Summary
Unlock Audio Lesson
Now that we've broken down the components, how can we find the total hourly cost of using our dump truck?
We add together the ownership costs, operating costs, and operator wages.
Exactly! The total hourly cost amounts to ₹6,122.29 when we sum up ₹2,713 for ownership and ₹3,209.29 for operating costs with ₹200 operator wages. Why is this important for management?
It helps in budget planning and understanding the overall financial impact of equipment usage.
Correct! Understanding these calculations aids in better project management decisions.

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. Now let us workout from examples on how to estimate the equipment cost using these 2 methods.
Detailed Explanation
In this section, we begin by recognizing the importance of calculating both ownership and operating costs for equipment. Ownership costs refer to all expenses associated with owning equipment, such as depreciation, interest, insurance, and taxes. Operating costs are the costs incurred during the operation of the equipment, including fuel and labor. Following Peurifoy's guidelines helps in systematically estimating these costs to create a comprehensive understanding of total expenses related to equipment use. Essentially, when you add both ownership and operating costs along with wages, you arrive at the total cost of operating a piece of equipment.
Examples & Analogies
Imagine you own a car. The ownership costs would include the car's purchase price, insurance, and any taxes you pay. The operating costs would include fuel, maintenance, and possibly the driver’s salary if you hired someone to drive for you. Together, these costs give you the complete picture of how much it truly costs to have and use the car.
Off-Highway Trucks and Their Costs

In this problem you can estimate the cost for the dump truck. It is an off highway truck, why we call it as off highway? This truck is not permitted on the public highways. It is a heavy equipment high end equipment you can see that these trucks will be operated only in the project sites. The initial cost is given so it was purchased with the deliver price of 3 crores.
Detailed Explanation
Here, we are introduced to the concept of off-highway trucks, such as dump trucks, which are specifically designed for use on construction sites rather than public roads. This distinction is important because it affects their design, utility, and cost structure. The initial cost for the truck is listed as 3 crores, which reflects its specialized equipment and capability. This high initial cost is primarily due to its robust construction and features required for rigorous outdoor work.
Examples & Analogies
Think of a dump truck as a specialized tool that belongs in a toolbox for construction. Just like how a high-quality wrench is necessary for specific plumbing tasks, a dump truck is essential for heavy hauling materials at construction sites. Its cost reflects its specialized use and the heavy-duty materials used in its construction.
Estimating Operating Costs

The truck is expected to have annual use of 1600 hours. Similarly, its useful life is estimated at 20000 hours. The local cost of fuel is 65 rupees per liter and the operating cost wage per hour is 200 rupees per hour.
Detailed Explanation
To estimate the operating costs, we first need to establish how often the truck will be in use. The truck is expected to run 1600 hours annually, with a total useful life estimated at 20000 hours. Thus, the total lifespan usage gives us a good measure of how to plan for maintenance or replacement costs. Knowing the cost of fuel and the wage for operating the truck allows us to calculate the total operating expenses. This gives us a baseline to work from when determining the efficiency and financial viability of using the truck.
Examples & Analogies
If you think about driving a car, you allocate your budget for how often you drive and the cost of petrol. Just like that, a construction company must anticipate how many hours a dump truck will work and how much that will cost in fuel and salary for the driver. By doing this, they create a more accurate budget for their projects.
