Today, we're going to discuss depreciation, particularly about how we calculate it for equipment costs. Can someone remind me what depreciation means?
Isn't it the reduction in value of an asset over time?
Exactly! We calculate depreciation to determine how much of an asset's value is used up each year. This helps businesses understand the cost of owning equipment. For example, how would we calculate the depreciation for a dump truck?
Do we need the initial price and how long we will use it?
Yes! We need the initial price, the useful life, and the salvage value. Let's break this down further.

For our dump truck, the initial cost is 3 crores and the tire cost is 11 lakhs. With a useful life of 12.5 years, how do we calculate the depreciation?
We subtract the tire cost from the initial cost and then divide by the useful life, right?
Correct! The formula shown is: . Who can tell me the result?
That would be approximately 23,12,000 per year!
Great! Now, let's also find out the hourly depreciation cost.

Now that we have the depreciation cost, how do we add other ownership costs?
We need to add insurance, taxes, and interest costs, right?
Exactly! Each can be calculated as a percentage of the average annual investment in the equipment. For our dump truck, using the interest cost of 8%, what would the hourly interest be?
I think it's around ₹780.30 per hour.
Fantastic! Now let’s calculate the total cost per hour including operating costs.
Overview
Short Summary
This section discusses how to calculate depreciation for equipment costs, using an example of a dump truck to illustrate the methods.
Medium Summary
This section provides a detailed explanation of depreciation calculation for equipment costs, focusing on the depreciation of a dump truck. It covers both ownership and operating costs, the relevant methodologies, and key factors impacting the calculation, including initial cost, useful life, and operating conditions.

Detailed Summary of Depreciation Calculation
This section delves into the calculation of depreciation as a crucial element in estimating the total cost of ownership for construction equipment. Using the example of an off-highway dump truck, it identifies the key components impacting the ownership cost, including initial purchase price, tire costs, and associated expenses such as insurance, interest, and taxes. The text explains that depreciation can be assessed utilizing the straight-line method since the salvage value is zero in this case.

The section further explores ownership and operating costs, elucidating the steps to evaluate hourly costs and the average annual investment approach. It wraps up by elaborating on how these useful calculations contribute to efficient budget management in construction projects.

Detailed Explanation
Depreciation is a method to allocate the cost of a tangible asset over its useful life. In this case, the depreciation formula considers the initial purchase price, subtracts the cost of tires and any salvage value (the estimated value of the asset at the end of its useful life). The remaining amount is divided by the useful life of the asset to determine how much value is lost each year. For instance, if a truck costs ₹3 crore and the tires are worth ₹11 lakhs, and it has no salvage value, the yearly depreciation will be determined based on its estimated lifespan.
Examples & Analogies
Think of it like a new car. If you buy a car for ₹10 lakh and expect it to last for 10 years with no resale value, each year you would consider that the car loses ₹1 lakh in value. This loss of value each year helps you understand how much the car is really worth as time goes on.

In this example:
Detailed Explanation
The useful life of the equipment is calculated based on how long it is expected to be operational. By dividing the total expected usage (20,000 hours in this case) by the annual usage (1,600 hours), we derive the useful life in years, which is 12.5 years. This means we expect the equipment to be used for 1,600 hours each year for the next 12.5 years until it is no longer functional.
Examples & Analogies
It's similar to a phone that you expect to last 5 years. If you use your phone for about 4 hours a day, you can calculate that over 5 years, that totals around 7,300 hours of use. Understanding how long you can expect to use your phone helps you make informed decisions about upgrades.

This leads to:
Detailed Explanation
This calculation walks us through each step of finding the annual depreciation, starting with the truck's initial price minus the tire cost and salvage value. When that number is divided by the useful life, we find the depreciation value per year, which we then convert to an hourly depreciation by dividing by the truck's annual usage in hours (1,600). Thus, each hour of operation effectively costs the business ₹1,445 in depreciation.
Examples & Analogies
Consider a business that buys a delivery van. If it cost ₹15 lakh and will be used for 5 years with no resale value, they would calculate the annual depreciation as ₹3 lakh each year. If they use the van for about 1,000 hours a year, that breaks down to ₹300 per hour in depreciation, helping them account for the vehicle's wear and tear in their operating costs.

- Hourly Depreciation
- Hourly Interest
- Hourly Insurance
- Hourly Taxes
Total Hourly Ownership Cost is calculated as:
Detailed Explanation
By adding up different ownership cost components, we get a comprehensive view of the total cost attributed to own and operate the equipment. This includes depreciation, interest for financing if applicable, insurance for asset protection, and taxes that come along with asset ownership. The computation results in a total hourly ownership cost of ₹2,713, which guides budgeting and financial forecasts for operations.
Examples & Analogies
Imagine owning a rental apartment; your ownership costs would include mortgage interest, property taxes, insurance, and wear-and-tear costs. Understanding those costs helps you set a rental price that covers your expenses and ensures profitability.

Key concepts
Core takeaways and short definitions to help you quickly recall the key ideas from this section.
- Depreciation:
The process of allocating the cost of a tangible asset over its useful life.
- Ownership Cost:
The total cost associated with owning an asset, including both depreciation and other costs.
- Operating Cost:
The costs incurred during the operation of an asset, including fuel, wages, and maintenance.
Examples
Step-by-step examples to apply the section's ideas and test your understanding.
For a dump truck with a purchase price of 3 crores and annual usage of 1600 hours, the depreciation calculated is approximately ₹2312000 per year.
Total hourly ownership cost for the dump truck combined with operating costs amounts to approximately ₹6122.29.
Memory aids
Depreciation's a calculation, on value it’s a fixation; subtracting tire costs and salvage too, spread over useful life’s due!
Imagine a dump truck working hard on a construction site, every year it loses some value. This truck's initial cost was high, but as the years go by, we keep counting the hours and figuring out how much value it has left.
