Understanding Initial Cost and Annualized Costs
Unlock Audio Lesson
Let's start by understanding how we convert the initial cost into an annualized cost. Can anyone tell me what the initial cost of the machinery is?
Is it ₹ 2,89,00,000?
Exactly! Now, we need to annualize this cost using a uniform series capital recovery factor formula. Who can remember what this involves?
It’s the interest rate and the number of years, right?
Correct! We use the formula: IC × [i(1+i)^n] / [(1+i)^n - 1]. For our calculation, the interest rate is 8% over 12.5 years. Can anyone calculate the annualized cost from that?
So, I think that would make the annualized cost ₹ 37,41,844.41.
Well done! This indicates how much we need to allocate annually for the initial cost.
What about the salvage value?
Great question! We'll discuss that next.
Calculating Salvage Value
Unlock Audio Lesson
Now that we understand the annualized initial cost, let’s talk about the salvage value. Can one of you recall what salvage value means?
Is it the value we expect to receive from the machine once it has completed its useful life?
Exactly! For our machinery, the salvage value is 20% of the initial cost. How would you calculate that?
It would be ₹ 2,89,00,000 × 0.2 = ₹ 57,80,000.
Right! Now we need to convert this salvage value into an annual cost using the uniform series sinking fund factor formula. Anyone know how to do that?
We divide the salvage value adjusted for the interest rate and lifespan, similar to before!
Correct, and if we calculate it, we find it to be ₹ 2,85,968.88 annually.
So how does this factor into our total operating cost?
We'll be building on that! Let's discuss hourly depreciation next.
Hourly Operating Costs
Unlock Audio Lesson
Now let’s calculate hourly depreciation. Remember, we take the total cost and subtract the salvage value before dividing by the annual hours of usage. Can anyone put that into the formula?
So, we take ₹ 37,41,844.41 minus ₹ 2,85,968.88 divided by 1600 hours?
Exactly! What do you get when you compute that?
It comes out to ₹ 2159.92 per hour.
Correct again! Now, moving on to ownership costs, let’s calculate insurance and taxes based on the initial cost. Who can tell me how to find the insurance cost?
Isn’t it 2% of the initial cost per hour? So, ₹ 2,89,00,000 × 0.02 divided by 1600?
Absolutely! And what about the taxes?
It would be 3%, so we would do the same calculation!
Perfect! Now, when we add everything up, what do we get as total ownership cost?
Cost of Consumables and Total Cost Calculation
Unlock Audio Lesson
Next, let’s estimate fuel and consumable costs. What do you think the fuel consumption factor is based on operating conditions?
That would depend on the horsepower and adjusted factors based on the load, right?
Exactly! With an operating factor of 0.5 and a horsepower of 250, we multiply that by 0.14 liters per horse power per hour. What do we get?
That means we consume 17.5 liters per hour!
Correct! Now multiply that by the fuel cost per liter to get the hourly fuel cost.
If the cost is ₹ 65 per liter, that’s ₹ 1137.50 per hour.
Great job! Now we add this to the total ownership costs to find the full operating cost.
Final Calculation and Adoption of Costing Methods
Unlock Audio Lesson
Finally, we synthesized all operational costs to find our total cost. Can anyone summarize what our total calculated cost per hour is?
It should be ₹ 5759.20 per hour when we add everything!
Well done! Now, just so everyone understands, how do methods like the Caterpillar method differ from this calculation?
The Caterpillar method uses average annual investment, while our method uses actual timed cash flows!
Exactly! It’s important to understand the implications of each method as companies will choose based on policy.
So, it ultimately comes down to business decisions!
Correct! Let’s summarize today’s lessons as we wrap up. We learned how to break down every component to obtain total operating costs effectively.

Detailed Summary of Total Operating Cost Calculation
In this section, we delve into the complexities of calculating total operating costs for machinery by converting the initial investment into an annualized format. Using the concept of uniform series capital recovery factor, the initial cost of ₹ 2,89,00,000, with an 8% interest rate and a lifespan of 12.5 years, results in an annualized cost of ₹ 37,41,844.41. Similarly, the salvage value, which is 20% of the initial cost, is annualized, yielding ₹ 2,85,968.88 per year.
Hourly depreciation is then calculated based on the difference between annualized costs and the annual usage hours of the machine (1600 hours), resulting in an hourly depreciation of ₹ 2159.92.
Further, ownership costs for insurance and taxes are included as percentages of the initial cost, leading to additional hourly costs of ₹ 361.25 and ₹ 541.88, respectively. By summing these amounts, we obtain a total hourly ownership cost of ₹ 3063.05.
Additionally, we discuss estimating fuel costs, FOG (Filter, Oil, Grease) costs, tire costs, and maintenance costs. For example, the estimated hourly fuel cost is ₹ 1137.50 after considering the hourly fuel consumption.
Finally, combining all these costs results in a comprehensive breakdown of the total operating cost of ₹ 5759.20 per hour, which reflects a thorough analysis and careful consideration of various cost factors.

Equivalent uniform annual cost of initial cost = Initial cost × [ i(1+i)^n / ((1+i)^n - 1) ]
Detailed Explanation
To calculate the annualized initial cost of a project or an asset, you first identify the initial cost and the interest rate. The formula used helps spread the total cost over the lifespan of the asset as an annual expense, which makes it easier to budget for. The key components of the formula are:
- Initial Cost is the total outlay for the project, i.e., ₹2,89,00,000.
- Interest Rate (i) represents the yearly cost of financing the investment (in this case, 8%).
- n is the estimated useful life of the asset (12.5 years in the example).
Using these values, the formula helps you compute how much you need to allocate each year to cover the initial expenses over the life of the asset.
Examples & Analogies
Think of this like purchasing a car. When you buy a car, you pay a lump sum. However, if you want to plan your monthly budget effectively, you would calculate how much you need to set aside each month for the car, which involves considering things like interest on a loan, much like we are doing here for an asset's cost.
Salvage Value Calculation

Equivalent uniform annual cost of salvage value = Salvage value × [ i / ((1+i)^n - 1) ]
Detailed Explanation
Salvage value is the estimated resale value of the asset at the end of its useful life. To convert this future value into an annual cost, you use a similar formula as with the initial cost. Here, the salvage value (20% of initial cost) is multiplied by the same factor to annualize it based on the interest rate and the life span of the asset. This approach allows for budgeting for any future profits gained from selling the asset.
Examples & Analogies
Imagine selling your old car. If you expect to sell it for ₹50,000 in 12.5 years, you want to know how much that future cash flow is worth in today's budget. By calculating the annual amounts, it’s akin to setting aside a certain sum each year for future savings.
Hourly Depreciation

Hourly Depreciation = (Annualized Initial Cost - Annualized Salvage Value) / Annual Use of Machine in Hours
Detailed Explanation
Hourly depreciation is the measure of how much value the equipment loses for each hour it operates. To calculate this, you subtract the annualized salvage value from the annualized initial cost to find the effective depreciation. Then, it's divided by the total operational hours in a year (in the case provided, 1600 hours). This gives a direct view of cost assigned to each hour of operation, ensuring accurate budgeting and forecasting.
Examples & Analogies
Consider a rental business. If you rent out a piece of equipment for 1 hour, you want to know how much it costs you per hour based on wear and tear. This calculation allows you to set rental fees appropriately.

Insurance, taxes, and storage components of ownership costs are calculated as a percentage of initial cost.
Detailed Explanation
Ownership costs include various factors that contribute to the total expense of maintaining assets beyond initial purchase price. Insurance, taxes, and storage costs should be calculated as a percentage of the initial cost after deducting any costs such as tires. These calculations help in determining what it actually costs to hold and operate the equipment on a day-to-day basis.
Examples & Analogies
When you own a house, your total cost of ownership isn't just the purchase price. You also pay property taxes, homeowners insurance, and maintenance costs. These shade the total view of owning that house, similar to this process.

Fuel cost is estimated based on consumption factors adjusted for project conditions.
Detailed Explanation
Fuel costs are essential operational costs calculated based on how much fuel the machinery consumes per hour of operation. This is derived from several factors, including the efficiency of the equipment and its workload during operation. The total operational time and conditions must be considered to give an accurate estimate of fuel costs based on current local prices.
Examples & Analogies
If you regularly fuel a car, you'll notice that your fuel cost varies depending on how you drive, the load in your car, and the road conditions. Similarly, machinery has variable fuel costs based on its operating conditions.

Total Operating Cost = Hourly Ownership Cost + Other Operating Costs + Operator Wages
Detailed Explanation
To arrive at the Total Operating Cost, all components of costs calculated so far need to be aggregated. The hourly ownership cost, alongside extra operating costs that include fuel costs, consumables, and any necessary maintenance, alongside operator wages, sum up the total hourly cost required for effective budgeting and planning.
Examples & Analogies
It's like preparing a family budget: you calculate monthly rent (ownership costs), add groceries and insurance payments (operating costs), and factor in any additional expenses (like utilities). This gives a complete picture of what it costs to run your household each month.
