Understanding Initial Cost and Annualized Cost
Unlock Audio Lesson
Today, we're going to learn how to estimate fuel costs starting with the initial investment. Can anyone tell me why calculating the annualized cost is important?
Is it because it helps us understand how much we need to budget yearly for this equipment?
Exactly! By converting one-time costs into annual expenses, it becomes easier to compare with other operational costs. We will use the formula I * (i(1+i)^n) / ((1+i)^n - 1). Can anyone remember what each part of this formula represents?
I remember that 'I' is the initial cost, and 'i' is the interest rate!
And 'n' is the number of years!
Well said! Remembering these concepts with the acronym 'I IN' can help. Now, let's apply this to our example with an initial cost of ₹2,89,00,000 at 8% over 12.5 years. What do we compute?
We find that the annualized initial cost is ₹37,41,844.41!
Great! Always remember the practicality of budgeting in your operations.
Salvage Value and Annualized Cost Calculation
Unlock Audio Lesson
Next, we'll discuss salvage value. What do we understand by salvage value in our context?
It’s the estimated resale value after the equipment is no longer usable.
Exactly, and we need to convert this into an annual equivalent as well. Can someone remind me of the formula for this?
It's the salvage value times some factor we learned earlier!
Correct! And for our example, the salvage value is 20% of the initial cost, which gives us ₹2,85,968.88 annually. Let's think about how this impacts our total costs. Why is this important?
It reduces the overall annual cost, showing more accurate ongoing expenses!
Exactly! Keep in mind that this value represents future savings.
Operating Costs and Hourly Calculations
Unlock Audio Lesson
Now that we've covered initial and salvage costs, how do we estimate hourly operating costs?
We need to look at depreciation and other costs like insurance and taxes, right?
Yes! We take our annualized costs and divide them by the annual usage in hours, which in our case is 1600 hours. What do we find for depreciation?
It's ₹2159.92 per hour!
Fantastic! Now let's break down the ownership costs including insurance and taxes. Can someone tell me the hourly insurance cost?
That would be ₹361.25 per hour!
Correct. By adding these costs, how do we find the total hourly ownership cost?
It's the sum of depreciation, insurance, and taxes!
Exactly! The total comes to ₹3063.05 per hour.
Fuel Consumption Calculation
Unlock Audio Lesson
Let's turn our attention to fuel costs. Can anyone describe the fuel consumption factor?
It's 0.14 liters per horsepower per hour under standard conditions.
Correct! Now, we need to adjust this based on real operating factors. What defines these factors?
The load factor and the time factor!
Exactly! With a working efficiency of 83%, we calculate our operating factor. How do we find our total fuel cost per hour?
We multiply the operating factor by rated power and the fuel consumption factor.
Well done! This involves some multiplication, and we find a fuel cost of ₹1137.50 per hour. Why is accurate fuel estimation critical?
It directly affects our operating costs and profitability!

Fuel Cost Estimation
In this section, we delve into the intricacies of fuel cost estimation for operational machinery. The core of our analysis involves converting initial costs into equivalent uniform annual costs using the uniform series capital recovery factor. For instance, we learned to calculate the annualized cost of an initial investment of ₹2,89,00,000 at an interest rate of 8% over a lifespan of 12.5 years, yielding an annual cost of ₹37,41,844.41.
Beyond initial costs, we explore salvage values, which also require conversion into equivalent uniform annual costs. By understanding the salvage value of machinery as 20% of its initial cost, we estimate an annualized salvage value of ₹2,85,968.88 using the uniform series sinking fund factor.
We then shift our focus to operational costs, particularly hourly depreciation and various ownership costs, including insurance calculated at 2% of the initial cost divided by operational hours, and taxes at 3%. As a result, we find the total hourly ownership cost to be ₹3063.05. Finally, by factoring in fuel consumption based on specific operational conditions, consumables like lubricants, and tire costs, we arrive at total hourly operating costs, demonstrating the comprehensive approach necessary for accurate fuel cost estimation.

Using uniform series capital recovery factor to convert initial cost into equivalent uniform annual cost.
The formula is:
\( A = I \times \frac{i(1+i)^n}{(1+i)^n - 1} \)
Where:
- \( I \) = Initial cost (₹2,89,00,000)
- \( i \) = Interest rate (8%)
- \( n \) = Useful life (12.5 years)
Annualized initial cost = ₹ 37,41,844.41/year
Detailed Explanation
To calculate the annualized initial cost, we use the uniform series capital recovery factor. This factor allows us to take a one-time initial cost and spread it across multiple years, taking into account the interest rate.
- The initial cost of the machine is ₹2,89,00,000.
- We apply the formula that includes the interest rate of 8% and the lifespan of the machine, which is 12.5 years.
- When we calculate it, we find that the annualized cost comes to approximately ₹37,41,844.41. This means each year, for 12.5 years, we would 'spend' that amount to represent the initial investment in our calculations.
Examples & Analogies
Think of it like a mortgage on a house. When you buy a house, you can’t just pay the full price upfront if it’s expensive. Instead, you pay a certain amount each month over many years. The bank considers interest in this payment. Annualized costs work similarly; we’re spreading out the expense of the machine over its useful life just like monthly mortgage payments.
Salvage Value Calculation

Converting future salvage value into equivalent uniform annual cost:
\( A = S \times \frac{i}{(1+i)^n - 1} \)
Where:
- \( S \) = Salvage value (20% of initial cost)
- Salvage value = 0.2 × ₹2,89,00,000 = ₹57,80,000
Annualized salvage value = ₹ 2,85,968.88/year
Detailed Explanation
The salvage value is the estimated resale value of the machine at the end of its useful life. To convert this future value into an annualized cost, we again use a formula similar to the one for the initial cost:
- First, we determine the salvage value which is 20% of the initial cost, making it ₹57,80,000.
- Then, we apply a formula that accounts for the interest and time. The result gives us about ₹2,85,968.88 annually.
- This figure now represents the annual income we can expect from selling the machine at the end of its useful life in our calculations.
Examples & Analogies
Imagine you buy a car worth ₹20 lakh, and after 10 years, you expect to sell it for ₹4 lakh. Instead of thinking of the ₹4 lakh as a one-time event, we can think of it as receiving a 'salary' of ₹40,000 every year over 10 years. Salvage value works the same; it helps to consider it in relation to annual costs.
Hourly Depreciation Calculation
Unlock Audio Book

Hourly depreciation is calculated as:
\( Hourly Depreciation = \frac{(A - SV)}{Annual\ use\ in\ hours} \)
Where:
- \( A \) = Annualized initial cost = ₹37,41,844.41
- \( SV \) = Annualized salvage value = ₹2,85,968.88
- Annual use = 1600 hours.
Hourly Depreciation = ₹ 2,159.92/hour
Detailed Explanation
To find the hourly depreciation, we calculate the difference between the annualized initial cost and the annualized salvage value, then divide that by the total hours the machine will be used annually:
- We take the annual cost from the first calculation (₹37,41,844.41) and subtract the annual salvage cost (₹2,85,968.88).
- This gives us the total depreciation over the year.
- Then, we divide this depreciation by the number of hours the machine will operate annually, which is 1600 hours. The result is ₹2,159.92 per hour, indicating how much value the machine loses each hour it's in use.
Examples & Analogies
Think of it like a pizza. If you buy a pizza for ₹1,000 and it’s expected to be worth nothing after you eat it all, you can think of the 'value lost' for each slice. If you eat it over 10 slices, you 'lose' ₹100 of value for each slice you eat. In this scenario, each hour of machine usage is like eating a slice, losing its value.
Total Hourly Ownership Cost

Calculating total hourly ownership cost involves:
- Hourly depreciation = ₹2,159.92
- Insurance cost = ₹361.25/hour
- Taxes = ₹541.88/hour
Total hourly ownership cost = ₹ 3,063.05/hour
Detailed Explanation
The total hourly ownership cost is found by adding together all the individual costs associated with owning and operating the machinery per hour:
- Start with the hourly depreciation which we calculated earlier as ₹2,159.92.
- We then add the insurance cost (₹361.25/hour) and the taxes (₹541.88/hour).
- Adding these together gives us the total ownership cost of ₹3,063.05 per hour, which represents all fixed costs associated with owning the equipment.
Examples & Analogies
Imagine you run a delivery business and need a van. You count all costs like the depreciation of the van, insurance for it, and the parking fees you pay. Just like calculating expenses for a single hour of owning and using the van, here we are summing everything up to see what it costs to own and operate the machine each hour.
Operating Cost Estimation

Estimating fuel costs involves:
- Fuel consumption factor: 0.14 liters/horsepower/hour.
- Rated horsepower: 250.
- Adjusted hourly fuel consumption = Operating factor x Rated power x Fuel consumption factor = 17.5 liters/hour.
Hourly fuel cost = 17.50 liters x ₹65/liter = ₹ 1,137.50/hour.
Detailed Explanation
To calculate the hourly fuel cost, we first identify how much fuel our machine uses:
- The fuel consumption factor tells us that our machine uses 0.14 liters for every horsepower it has.
- Since our machine has a power rating of 250 horsepower, we can calculate that it will use around 35 liters for its total capacity.
- However, we also consider the 'operating factor' which accounts for real-world conditions and reduces this to 17.5 liters an hour.
- Finally, we multiply this number by the price of fuel to get the hourly cost, which is ₹1,137.50.
Examples & Analogies
Think of your car driving in a city; it consumes more fuel per kilometer than on a smooth highway due to stop-and-go traffic. Just like fuel consumption may vary based on conditions, in this calculation, we adjust for how the machine actually runs in a working environment to find out what it costs to keep it going.
