Today we are going to explore the cost of investment associated with machinery. It is crucial to understand how it's calculated and the implications for ownership costs. Can anyone tell me what they think the cost of investment entails?
I think it includes the money we spent to buy the machines.
Good point! The cost of investment does include the purchase price. It also includes opportunity costs like the interest on borrowed funds or the potential returns from alternative investments. Remember the acronym **C.O.I.** - Cost of Investment involves both Capital and Opportunity.
So, whether we buy or finance the machine, we still have an investment cost?
Exactly! Both scenarios require us to consider these costs.

Now let’s delve into how we can calculate this cost. There are two main methods: the time value method and the average annual investment method. Can anyone explain what these methods might involve?
Isn’t the time value method about adjusting for inflation or interest over time?
Exactly! The time value method accounts for changes in cash flow timing, using factors for compound interest. Great thinking! Now, what about the average annual investment method?
I think it uses averages to simplify calculations over the equipment's life.
Right again! It expresses the cost as a percentage of the average value of the equipment during its lifespan.

Apart from the cost of investment, what other components contribute to the total ownership cost we discussed?
There's depreciation and probably insurance?
"Correct! We also include taxes and storage costs. These are typically expressed as a percentage of the average value of the machine. So remember, the formula is:

Let’s summarize with a practical example. Suppose a machine costs 82 lakhs and has a salvage value of 12 lakhs over 9 years. How would we calculate the average annual investment?
We'd use the formula: **P(n+1) + S(n-1) / 2n.**
That's right! After calculating, we'd also express all other ownership costs as percentages of this average annual investment.
And then divide by operating hours to get costs per hour?
Exactly! You’re really getting the hang of this.
Introduction & Overview
Read summaries of the section's main ideas at different levels of detail.
Quick Overview
Standard
The section elaborates on the cost of investment associated with machinery ownership, explaining how this cost can be derived from either borrowed funds or company assets. It details two calculation methods: the time value method, which considers the timing of cash flows, and the average annual investment method, which simplifies calculations based on the average value of the asset over its useful life.
Detailed
Detailed Summary
The cost of investment represents the annual expense related to the capital tied up in machinery and equipment ownership. This section delineates the two prevalent methods utilized to calculate the cost of investment:
- Time Value Method: This method emphasizes the timing of cash flows, adjusting them to present value using compound interest factors. It provides an accurate representation of the cost of investment by reflecting the time value of money.
- Average Annual Investment Method: This approach approximates the cost based on the average investment over the lifespan of the asset. It calculates the average value of equipment through depreciation and simplifies ownership cost estimation by expressing it as a percentage of the average yearly investment.
Key Points:
- The cost of investment is derived from either the interest paid on loans for purchasing equipment or the opportunity cost of using company assets.
- Calculating Average Value: The average value of the machine is determined using the initial purchase price and the estimated salvage value, factoring in the useful life of the asset.
- Equipments incur additional ownership costs such as insurance, taxes, and storage, which are similarly expressed as percentages of the average value.
- A practical example illustrates how to derive the hourly ownership cost using the average annual investment method.

Investment cost represents the annual cost of capital invested in the machine, similar to the cost of acquiring ownership of the machine. This may arise from purchasing a machine through borrowed funds or through company assets.
Detailed Explanation
The cost of investment is a crucial factor in determining the overall ownership cost of a machine. It encompasses the annual capital cost associated with owning a machine. Whether the machine is purchased outright or financed through loans, there will be costs associated with these investments. When acquiring a machine using borrowed funds, the interest paid on that loan is considered as part of the investment cost. If the machine is purchased using company assets, the opportunity cost—represented by the interest rate that could have been earned if that money had been invested elsewhere—should also be considered in the investment cost.
Examples & Analogies
Think of it like choosing between buying a new car or investing that money in a business. If you buy the car, the money is tied up and not earning interest. But if you invest it, you expect to make some returns. The investment cost reflects the 'cost' of that lost opportunity or the loan interest paid.

The cost of investment can be calculated using two methods: the time value method and the average annual investment method. The time value method is more accurate as it considers the timing of cash flows over the useful life of the machine.
Detailed Explanation
There are two primary methods to calculate the cost of investment. The time value method involves analyzing cash flows that occur at different times and adjusting them to a common time period for accurate comparison. This method uses compounding interest factors to account for the time value of money, ensuring that future cash flows are evaluated in today's monetary terms. In contrast, the average annual investment method approximates the cost as a percentage of the average value of the machine over its useful life, simplifying calculations while taking depreciation into account.
Examples & Analogies
Imagine you have a savings account. If you deposit money today, it earns interest over time. The time value method looks at how much that deposit grows over the years by considering how much more you'd have if you invested the same amount instead of spending it. The average annual investment method, on the other hand, is like estimating how much you've saved every year averaged out over the time you had your account, giving a simpler but often less precise picture.

The time value method considers cash flows at different time intervals to convert all cash flows into an equivalent value for a specific time period, providing a more rational analysis.
Detailed Explanation
The time value method is grounded in the finance principle that a dollar today is worth more than a dollar in the future due to its potential earning capacity. By analyzing cash flows occurring at various periods, this method converts them into a standardized equivalent value. This is essential for making accurate comparisons in investment decisions. The method involves using appropriate compound interest factors to convert those future cash flows back to present value, thereby enhancing the accuracy of the investment cost calculation.
Examples & Analogies
Consider planning a vacation costing $1,000 today versus a trip costing $1,000 a year from now. Due to inflation and potential earnings on that money, the $1,000 today is more valuable. If you use the time value method to calculate these costs, you would account for how much value that dollar could earn if invested instead of spent.

The average annual investment method estimates the cost of investment as a percentage of the average value of the machine over its useful life, simplifying calculations.
Detailed Explanation
In the average annual investment method, the cost of investment is calculated based on the average value of the machine throughout its lifespan. As the machine depreciates, its average value decreases, making it easier to express the ownership costs as a percentage of this average. This method provides approximations for the investment cost that aligns with other components like depreciation and insurance. By estimating costs as a percentage, it simplifies financial evaluations and aids in overall cost management.
Examples & Analogies
Think of it as averaging the heights of a bunch of plants over their growth period. Initially, they might be small, but as they grow, they reach a peak height and then start to wilt. By taking an average height at different growth stages, you can evaluate the overall health of your garden more easily than by measuring individual heights at various points in time.

Ownership costs include depreciation, investment cost, insurance cost, taxes, and storage. Total ownership cost is the sum of all these components.
Detailed Explanation
Understanding ownership costs is vital for effective financial planning in equipment management. It involves several components: depreciation, which accounts for the loss of value; investment costs, which reflect the financial commitment; insurance costs to protect against risks; taxation related to the property; and storage costs for maintaining the equipment when not in use. Summing these costs provides the total ownership cost, essential for budgeting and strategic financial decisions.
Examples & Analogies
It's like managing a household budget where you need to pay for mortgage (depreciation), insurance, property taxes, and maintenance for the house. Just as you would sum up all these expenses to understand your financial outlay for living in your home, in equipment management, you sum all ownership costs to understand your total investment in the machinery.
