Understanding Ownership Costs
Unlock Audio Lesson
Today, we're looking at ownership costs. What are some components we should consider when calculating these costs?
I think things like the purchase price and depreciation?
Correct! We also consider interest, insurance, and taxes. Who can tell me how we calculate depreciation?
Is it based on the useful life of the equipment?
Exactly! We usually use the straight-line method to calculate it. We take the initial price, subtract any costs like tire costs, and divide by the useful life. Can anyone remember the useful life in our example?
It's 12.5 years based on the 20,000-hour lifespan!
Great job! Recollecting these figures is important for clear calculations in budgeting.
Calculating Operating Costs
Unlock Audio Lesson
Now, let's shift to operating costs. What elements do we need to account for?
Fuel and maintenance costs?
Correct! And labor costs too. We calculate fuel costs using consumption factors, right?
Yes! It's based on horsepower and the fuel cost per liter!
Exactly! For our dump truck example, the fuel cost was calculated to be ₹1462.50 per hour. Can someone explain how we got there?
We multiplied the fuel consumption factor by the horsepower and the local fuel price!
Right! Keeping these calculations consistent is key for accurate reporting.
Combining Costs to Determine Total Cost
Unlock Audio Lesson
So far, we've calculated ownership and operating costs. How do we find the total equipment cost?
By adding them together, right? Plus any wages?
Correct! In our case, it totaled ₹6122.29 per hour. It's crucial to account for operator wages too.
What if we have salvage value? Does that change anything?
Great question! Salvage value reduces the initial cost, affecting depreciation and ultimately reducing ownership costs.
So, all these numbers can shift depending on just a small factor?
Exactly! This is why precise inputs are essential for accurate financial planning.

Total Equipment Cost Calculation
In construction and equipment management, accurately calculating the total cost of equipment is crucial. This section outlines how to estimate both ownership and operating costs following the Peurifoy guidelines.
- Ownership Costs: This includes the initial purchase price, depreciation, interest, insurance, and taxes. For instance, we calculate the depreciation using the straight-line method, considering the initial value of a dump truck minus tire costs and salvage value divided by its useful life. The initial cost for a high-end dump truck is given as ₹3 crores, with additional costs such as tires, which are ₹11 lakhs. The useful life was determined to be 12.5 years based on its expected usage of 20,000 hours and annual usage of 1,600 hours.
- Operating Costs: These costs encompass items like fuel, maintenance, and labor. For example, we find the fuel cost based on a consumption factor derived from the equipment handbook. The section highlights that the total operating cost includes various components, accounting for average usage and local fuel costs.
- Calculating Total Cost: We combine both ownership and operating costs, along with other expenses like operator wages, to arrive at the total equipment cost, exemplified with numerical calculations.
Understanding these costs is vital for effective budgeting and project management in construction.

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're discussing how to calculate the total equipment cost, which involves adding together several key components including the ownership costs, operation costs, and wages associated with operating the equipment. The method referenced, the Peurifoy guidelines, provides a framework for accurately estimating these costs through examples.
Examples & Analogies
Think of this calculation like budgeting for a vacation. Just as you would consider airfare, hotel, meals, and activities, when calculating equipment costs, you need to account for ownership, operation, and wage costs to understand the total expense involved.

You can see this problem in this problem you can estimate the cost for the dump truck. It is an off-highway truck. Why do we call it as off-highway? This truck is not permitted on the public highways...special features like you can see it will be kind of articulate machine with any additional features are there with this dump truck that is why you can justify its cost.
Detailed Explanation
In this part, the focus shifts to a specific example: an off-highway dump truck. These trucks, designed for heavy-duty operations, cannot operate on public roads and are typically used at project sites. Their high costs can be attributed to their specialized features and capabilities tailored for tough environments.
Examples & Analogies
Imagine buying a specialized vehicle like a bulldozer that is made for construction. Just as this vehicle would cost more than a regular car because of its added features and capabilities, the dump truck's costs are justified based on its unique specifications.

The requirements are according to the type of the machine for which you are going to estimate. You can choose the appropriate estimation handbooks and choose the values estimated accurately. These numbers are just approximate assumptions just to show the methodology of how to estimate the economic cost.
Detailed Explanation
The cost estimation process involves using appropriate handbooks tailored to specific types of machines to derive accurate values. While some numbers presented in the example may be approximations, the intention is to demonstrate the approach and methodology behind estimating economic costs for equipment.
Examples & Analogies
If you were estimating the cost of a new computer, you would reference a technology price guide to ensure your numbers reflect current market values. Similarly, those estimating equipment costs will refer to established resources to guide their calculations.

Now we shall calculate the depreciation. Depreciation = (Initial price - Tire cost) / Useful life.
Detailed Explanation
Depreciation is discussed in terms of how to calculate it based on the initial cost of the equipment minus any specific costs, like tires. Here, the useful life of the equipment is used as a timeframe over which its cost will be spread out. This helps spread the cost of the machine over its expected lifespan.
Examples & Analogies
Imagine buying a car for $20,000 and predicting it will last for 10 years. You may consider that $20,000 cost in your annual budget as though it depreciates, allowing you to understand how much value you're losing each year.
