Today, we will discuss how to estimate the initial costs of machinery and how to annualize those costs. This is a crucial part of cost estimation in projects.
How do we annualize the initial cost?
Good question! We use the formula for equivalent uniform annual cost: Initial Cost times the uniform series capital recovery factor. For example, if our initial cost is ₹2,89,00,000 and the interest rate is 8% over 12.5 years, we can use the formula to convert it into an annualized cost.
So, does this mean we take into account the interest rate and the lifespan of the machine?
Exactly! Interest and lifespan are key to accurately reflecting costs. This creates a more manageable figure to work with in budgets.
Can you remind us of the formula?
Certainly! The formula is: IC × [ i(1+i)^n / ((1+i)^n - 1)]. This helps to determine how much we need to account for annually.
Got it! We do this to budget effectively for our projects.
Absolutely! Remember, this is part of strategic financial planning. Let's summarize our discussion: We learned how to annualize costs using specific formulas and the importance of considering interest rates and lifespan.
Calculating Salvage Values

Now, let's look at salvage values. Why do you think it's important to consider salvage values in our cost estimation?
Maybe because it reduces the overall cost we need to account for?
Exactly! The salvage value represents what we will get back at the end of the machine's useful life. We will convert it into an annualized figure as well.
What’s the formula for that?
We calculate it similar to the initial cost but apply a new factor for the salvage value. It would look like: SV × [ i / ((1+i)^n - 1)]. So if your salvage value is 20% of the initial cost minus the tire costs, you apply that ratio through the same formula.
So it still involves the same interest rate and lifespan?
Correct! The same factors apply. Let's summarize: We discussed that the salvage value reduces overall expenses and how to convert that into an annualized cost.
Understanding Ownership Costs

Next, let’s explore ownership costs. Can anyone list some components of ownership costs?
Depreciation, insurance, and taxes?
That’s right! Let's tackle depreciation first. How do we calculate that?
Isn't it based on the initial cost and its salvage value?
Yes! The formula is: (Annualized Initial Cost - Annualized Salvage Value) / Annual Use in Hours. This gives you an hourly depreciation.
And what about insurance?
Insurance is usually a percentage of the initial cost. For example, 2% of the initial cost divided by total hours used.
And taxes are similar, right?
Exactly! When we sum all these components, we can calculate the total hourly ownership cost. To conclude, we defined key components: depreciation, insurance, and taxes in relation to ownership costs.
Estimating Operational Costs
🔒 Unlock Audio Lesson

Let’s shift to operational costs, starting with fuel expenses. Why are they vital for our overall cost estimation?
Because they can add up quickly if not properly estimated.
Good point! We need to account for the fuel consumption based on the machine's efficiency. The fuel factor, for instance, can be expressed as liters per horsepower per hour.
How do we adjust that for project conditions?
You adjust it using the operating factor, which combines load and time factors. For instance, if your factor is 0.5, that will significantly affect your calculations.
What about other consumables?
Similar estimation processes apply for consumables like FOG costs, which can be derived as a percentage of fuel costs. To summarize, we emphasized the assessment of fuel and other consumables in estimating operational costs.
Calculating Total Costs

Finally, we’ll calculate total costs. Can anyone tell me the components we need to consider?
Ownership costs and operational costs?
Excellent! How do we combine them?
We simply add them together!
Exactly! For instance, if your ownership cost is ₹3,063.05/hr and your operational cost is ₹2,496.15/hr, your total cost per hour will be ₹5,759.20.
So, this is crucial for budgeting and financial analysis in projects?
Yes! Summing these costs provides a comprehensive view for proper decision-making. In summary, we learned to integrate ownership and operational costs to derive total project costs.
Introduction & Overview
Read summaries of the section's main ideas at different levels of detail.
Quick Overview
Standard
The section elaborates on cost estimation processes such as the calculation of equivalent uniform annual costs for initial and salvage values of machinery, the ownership costs including depreciation, insurance, and taxes, as well as operational costs like fuel and consumables. It emphasizes on various factors and formulas used in these calculations to provide accurate equipment cost estimations.
Detailed
FOG Cost Estimation
This section covers the process of estimating the costs associated with equipment ownership, emphasizing on key components like the initial costs, salvage values, and operational expenses. We begin by understanding the equivalent uniform annual costs.
Initial Costs and Annualization
Using the formula for equivalent uniform annual cost, we convert the initial equipment cost into an annualized format. For instance, with an initial cost of ₹2,89,00,000 and an interest rate of 8% over 12.5 years, the annualized cost turns out to be approximately ₹37,41,844.41.
Salvage Value Calculation
Next, we discuss how to annualize the future salvage value, which is calculated similarly to the initial cost but applying the salvage value percentage (20% of the initial cost minus tire costs). In our example, this results in an annualized salvage value of ₹2,85,968.88.
Ownership Costs
We then move to breakdown ownership costs into components including depreciation, insurance, and taxes. For instance, with calculated depreciation of ₹2,159.92 per hour, and insurance calculated at 2% of the initial cost, we derive total hourly ownership costs as ₹3,063.05.
Operational Costs
The section further discusses estimating operational costs like fuel consumption using specific formulas based on operational and load factors, which results in hourly fuel costs of ₹1,137.50, along with the FOG (Filter, Oil, Grease) costs that amount to ₹108.29/hr. We conclude the operational cost estimations by calculating tire costs and the associated repair and maintenance expenses.
Finally, combining all components gives us a complete estimate of operational and ownership costs, which is crucial for effective project budgeting and financial planning.

(1+0.08)12.5−1
So this IC is named equivalent to A using uniform series capital recovery factor.
Detailed Explanation
This chunk explains the calculation of the Equivalent Uniform Annual Cost (EUAC) for initial costs. You start with the initial cost, which in this case is ₹2,89,00,000. By applying a defined interest rate (8%) over a specific time period (12.5 years), the formula used helps convert the lump sum initial cost into a manageable annual cost. The result, ₹37,41,844.41, represents the equivalent annual payment required to recover the initial investment over 12.5 years, factoring in interest.
Examples & Analogies
Imagine you want to buy a car worth ₹2,89,00,000. If you don't have the full amount upfront, you consider a bank loan with an interest rate of 8%. To understand how much you'd pay annually to manage this loan, you'd use a similar formula, which would help you break down that massive price you need to pay into something smaller, just like dividing a large pizza into slices makes it easier to consume.

Now let us move on to the salvage value. So now I need to convert the future salvage value into equivalent uniform annual cost.
Detailed Explanation
In this chunk, the focus shifts to calculating the Equivalent Uniform Annual Cost (EUAC) of the salvage value. The salvage value is considered 20% of the initial cost minus the costs associated with the tires. The formula for this valuation converts the estimated future salvage amount into an annual equivalent, ensuring that this future value is factored into the equipment cost calculations, resulting in a useful annual figure for budgeting.
Examples & Analogies
Think of the salvage value like the amount you'd expect to sell your car for after several years. Just as you would want to understand how much profit you could reclaim annually from the sale of your car in the future, this cost estimation does something similar for industrial equipment by spreading that future value out into manageable annual costs.

Hourly depreciation, depreciation is nothing but the difference between the initial cost minus the salvage value and you are going to divide by the annual use of the machine in hours.
Detailed Explanation
This chunk describes how to calculate the hourly depreciation of the machinery based on its initial cost and expected salvage value. You subtract the annualized salvage value from the annualized initial cost, and then divide that number by the number of hours the machine is used each year (1600 hours in this example). This calculation gives a clear picture of how much value the machine will lose each hour of operation.
Examples & Analogies
Consider a new computer you bought for ₹37,41,844.41. If you expect to sell it for ₹2,85,968.88 after five years, you would primarily use it for work. Calculating how much value your computer loses each time you use it can help you understand its true 'cost' to you per hour.

Now add the total hourly ownership cost at all the components.
Detailed Explanation
This chunk illustrates how to determine the total hourly ownership cost for a piece of equipment. Each component of cost, including hourly depreciation, insurance, and taxes, contribute to establishing a complete picture of how much it costs to own and operate the equipment per hour. The total is found by summing these individual costs to arrive at an hourly rate.
Examples & Analogies
Imagine you own a coffee shop. Each month, you have specific costs for rent, utilities, and employee salaries. When you calculate the total monthly costs, you're essentially finding out how much it costs to keep your business running each hour. Similarly, in equipment estimation, combining all ownership costs provides insight into how much you're spending to operate that machine on an hourly basis.

Detailed Explanation
This final chunk consolidates all parts of the equipment's costs into a total hourly operating cost. By factoring in ownership costs, fuel costs, and maintenance costs, the comprehensive figure provides important insight for operational budgeting. This total becomes essential for decision-making and planning in financial contexts.
Examples & Analogies
Imagine going out to dinner. The menu shows the price of each dish, but you also need to consider drinks, appetizers, and tips. When you total everything up, you get the overall cost of your dining experience. Similarly, here the total operating cost aggregates everything needed to understand the true cost of running that equipment on an hourly basis.
