4. Depreciation and Book Value

Now, let us move on to the next important component of the ownership cost and that is your cost of investment. So, investment cost represents the annual cost of capital invested in the machine.

Investment cost refers to the annual expenses incurred to acquire and maintain machinery or equipment. This encompasses the costs incurred whether the equipment is purchased outright using company assets or financed through loans. This cost is vital because it directly affects the overall ownership cost of machinery.

Think of investment cost like the interest you pay when you take out a mortgage to buy a house. Just as you pay interest on that loan yearly until it's paid off, companies must account for the costs associated with investing in machinery, whether through interest on loans or the potential returns lost by using the funds for the equipment instead of other investments.

The investment costs is nothing but your interest rate multiplied by the value of your equipment.

To quantify investment costs, you simply multiply the interest rate by the value of the equipment. This formula indicates how much the cost of the machine impacts the overall investment expense. Whether the machine was bought outright or financed, this calculation will help assess the annual cost associated with using the equipment.

Imagine you buy a car worth $20,000 at an interest rate of 5$1,000 (0.05 x $20,000). This is similar to how businesses assess investment costs for machinery.

The cost of investment can be calculated by 2 different methods, as I told you earlier, one is a time value method and the other one is an average annual investment method.

There are two primary methods to calculate investment costs. The time value method considers the different timings of cash flows to provide a precise calculation that reflects the present value of future costs. On the other hand, the average annual investment method provides a simpler estimate by averaging the investment costs over a given period. Understanding these methods is crucial for accurate cost estimation.

Think of it like saving for a vacation. If you save $100 every month for a year, how much will you have at the end? The average method looks simply at the total amount saved, while the time value method considers how some of that money could have been earning interest if invested elsewhere.

The time value method is going to be a very accurate method. Basically, you know that the cash flows are occurring at different time intervals.

The time value method requires converting all cash flows, such as costs and revenues, into a common point in time. This is done by discounting future cash flows to their present value using appropriate interest factors, which allows for more accurate financial analysis and comparisons across different time periods.

If you plan to receive $1,200 a year from now, it's worth less today because you can't invest that money now. The time value method helps factor this 'time' into financial calculations, much like how you're calculating the worth of future income streams.

There is another method which is going to approximate it called average annual investment method.

The average annual investment method estimates costs as a percentage of the average value of the machine over its useful life. This method simplifies estimates by using an average value instead of accounting for the precise depreciation and timing of cash flows. While it's not as accurate as the time value method, it provides a quick way to gauge ownership costs.

If you think about how average grades are computed, if you score high on some tests and low on others, averaging those scores gives you a clearer picture without going into each individual score's timing and weight.

So, let us summarize what are all the components ownership costs we have discussed so far. So, the components of the ownership costs are the depreciation, the cost of investment, insurance cost, the property taxes and the storage cost.

Total ownership costs for machinery encompass several components: depreciation represents the equipment's loss of value over time, the cost of investment includes interest or opportunity costs, while insurance, taxes, and storage costs contribute to the total expense of maintaining and operating the equipment.

Think of owning a home: you not only pay the mortgage (investment cost) but also property taxes, homeowners insurance, and maintenance costs—all these factors combine to represent your total ownership expense.
