Annualized Initial Cost
Unlock Audio Lesson
Today we're going to learn how to calculate the annualized initial cost. Can anyone tell me what factors we need?
The initial cost and the interest rate?
Exactly! We also need the useful life of the equipment in years. The formula we use is: $$ A = I \times \frac{i(1+i)^n}{(1+i)^n - 1} $$. Let's understand this step-by-step.
What do those letters stand for?
Good question! $I$ is the initial cost, $i$ is the interest rate, and $n$ is the number of years. If the initial cost is ₹2,89,00,000, interest is 8%, and the lifespan is 12.5 years, what do we get as A?
I think that would be ₹37,41,844.41 per year.
Correct! This annualized cost helps us understand the yearly investment needed.
In summary, the annualized initial cost provides a clearer picture of yearly expenditures necessary to use the equipment.
Annualized Salvage Value
Unlock Audio Lesson
Next, let’s calculate the annualized salvage value. Why do we need this value?
To estimate how much we can earn from the equipment when we sell it later?
Exactly! The formula we use is: $$ A_{SV} = SV \times \frac{i}{(1+i)^n - 1} $$, where $SV$ is the salvage value. What is the salvage value here, taking 20% of our initial cost?
That's ₹57,80,000!
Good! Now, plug this into the formula with 8% interest and 12.5 years. What do we get for the annualized salvage value?
I calculate about ₹2,85,968.88 per year.
Well done! Now we can assess how salvage value impacts overall costs.
In summary, annualized salvage value gives us insight into potential returns at the end of our investment period.
Ownership Cost Components
Unlock Audio Lesson
Now, we need to combine our values for hourly depreciation. Can someone explain how we find this?
We take the annualized initial cost and subtract the annualized salvage value!
Exactly! Then we divide this by the total usage in hours. Let's say we plan to use the machine for 1600 hours a year. What does this yield for hourly depreciation?
That should be about ₹2159.92 per hour.
Very good! Now let’s talk about total ownership costs. It includes depreciation, insurance, and taxes. Can anyone recall how we compute the insurance cost?
It's 2% of the initial cost divided by the usage hours.
Perfect! Summing everything gives you the total hourly ownership cost. What does that equate to?
₹3063.05 per hour!
Excellent job! This helps summarize all costs we need to budget for equipment.
Operating Costs Estimation
Unlock Audio Lesson
Finally, we’ll estimate operating costs like fuel consumption. Who remembers our fuel consumption factor?
It’s 0.14 liters per horsepower per hour.
Correct! Adjusting for our operating conditions, what do we calculate if our machine has 250 horsepower and an operating factor of 0.5?
That's 17.50 liters per hour.
Great! Now, let’s calculate the fuel cost at ₹65 per liter. What does that come out to?
I think it’s ₹1137.50 per hour.
Exactly! These operating costs, along with ownership costs, summarize our total cost. Can anyone tell me what this means for total budgeting?
It helps us understand the comprehensive costs related to operating the equipment!
Exactly right! Keeping track of these costs is essential for efficient budgeting and project management.

Ownership Cost Calculation
This section delves into the various components involved in calculating ownership costs for equipment. The concepts covered include:
- Annualized Initial Cost: This is the equivalent uniform annual cost derived from the initial investment amount using the uniform series capital recovery factor. It is calculated with the formula:
$$ A = I \times \frac{i(1+i)^n}{(1+i)^n - 1} $$
where:
- $A$ = annualized initial cost
- $I$ = initial cost of the equipment
- $i$ = interest rate
- $n$ = useful life of the equipment in years.
- Annualized Salvage Value: The salvage value at the end of its useful life is converted into an annual equivalent using a similar approach. The formula used here incorporates a uniform series sinking fund factor.
- Hourly Depreciation: The hourly depreciation is derived by calculating the difference between annualized initial costs and annualized salvage value, divided by the annual usage hours.
- Total Hourly Ownership Cost: This combines hourly depreciation, insurance (as a percentage of initial cost), taxes, and any other ownership costs to provide a complete picture of the total costs.
- Operating Costs: Estimates of fuel consumption, maintenance (FOG costs), tire costs, and labor are included, deriving a broader understanding of costs associated with operating the equipment.
Each of these components is essential for accurately assessing the economic feasibility and budgeting for equipment use in projects.

The equivalent uniform annual cost of initial cost = Initial cost × [ (i(1+i)ⁿ) / ((1+i)ⁿ - 1) ]
Initial Cost: ₹ 2,89,00,000
Interest Rate (i): 8%
Useful Life (n): 12.5 years
Annualized Initial Cost = ₹ 37,41,844.41/year.
Detailed Explanation
To calculate the equivalent uniform annual cost of the initial cost, we use a specific formula that takes into account the interest rate and the useful life of the investment. Here, we have an initial cost of ₹ 2,89,00,000. Using the formula, we can find the annualized cost over 12.5 years at an interest rate of 8%. After performing the calculations, we find that the annualized cost amounts to ₹ 37,41,844.41 per year. This means that if you need to pay off the initial amount over 12.5 years with interest, your effective yearly payment will be ₹ 37,41,844.41.
Examples & Analogies
Think of it like buying a car. If you buy a car for ₹ 2,89,00,000 and take a loan at an interest rate of 8% to pay it off over 12.5 years, instead of paying the full amount upfront, you will be paying smaller amounts of ₹ 37,41,844.41 every year until the loan is settled. This makes it easier to manage payments rather than a large sum all at once.
Annualized Cost of Salvage Value

Equivalent uniform annual cost of salvage value = Salvage Value × [ (i) / ((1+i)ⁿ - 1) ]
Salvage Value: ₹ 57,80,000 (20% of initial cost)
Annualized Salvage Value = ₹ 2,85,968.88/year.
Detailed Explanation
Next, we need to assess the salvage value of our asset, which is the expected value when it is sold at the end of its useful life. Here, we've calculated the salvage value as 20% of the initial cost, which is ₹ 57,80,000. We again use a formula similar to the one for the initial cost. After calculating, the annualized salvage value is found to be ₹ 2,85,968.88. This figure represents an amount we can expect to receive each year in present value terms, based on the salvage value.
Examples & Analogies
Imagine if you sell your car for ₹ 57,80,000 after 12.5 years of using it. Just like before, instead of thinking of that final amount as just a lump sum, we convert it to an annual figure that reflects what you could expect or value each year from selling the car after its usage. So, every year, think of it as if you’re setting aside or earning ₹ 2,85,968.88 from that future sale.
Calculating Hourly Depreciation
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
Hourly Depreciation = (Annualized Initial Cost - Annualized Salvage Value) / Annual Use of Machine in Hours
= (₹ 37,41,844.41 - ₹ 2,85,968.88) / 1600 hours
= ₹ 2159.92/hour.
Detailed Explanation
To find the hourly depreciation of the equipment, we take the annualized cost of using the machine and subtract the annualized salvage value. This difference represents the actual cost of using the machine. We then divide this figure by the total hours the machine is expected to operate in a year, which is 1600 hours in this example. After performing the calculation, the hourly depreciation comes out to ₹ 2159.92. This means for every hour the machine is running, you are effectively 'losing' ₹ 2159.92 in value.
Examples & Analogies
Think of it like a bicycle you bought for ₹ 37,41,844.41. If you know you can sell it for ₹ 2,85,968.88 after a year, you can calculate how much value the bike loses each hour you ride it. So if you ride it for 1600 hours, that breakdown of depreciation makes it clear how much each ride is costing you in terms of the bike's value.
Additional Ownership Costs (Insurance, Taxes)
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
Insurance = 2% of (Initial Cost - Tire Cost) / Annual Use
Taxes = 3% of (Initial Cost - Tire Cost) / Annual Use
Hourly Insurance Cost = ₹ 361.25/hour
Hourly Taxes = ₹ 541.88/hour.
Detailed Explanation
The ownership cost of equipment is not only determined by depreciation but also includes additional costs like insurance and taxes. To find these, we calculate them as percentages of the initial cost (minus tire costs) and divide by the annual use of the equipment in hours. Here, insurance costs ₹ 361.25 per hour and taxes add another ₹ 541.88. These costs are important because they represent ongoing financial obligations that occur while the equipment is in use.
Examples & Analogies
Consider owning a car (or your earlier bicycle!). Just like you pay a monthly insurance fee and maybe some taxes on it, these costs accumulate every hour you use the vehicle. So just like understanding the depreciation gives a clearer picture of value loss, these additional costs give a clearer cost of ownership when you operate your vehicle.
Total Hourly Ownership Cost

Total Hourly Ownership Cost = Hourly Depreciation + Hourly Insurance + Hourly Taxes
= ₹ 2159.92 + ₹ 361.25 + ₹ 541.88
= ₹ 3063.05/hour.
Detailed Explanation
Finally, we aggregate all the different components of ownership costs to come up with a total hourly ownership cost. By adding the hourly depreciation, insurance, and taxes together, we find that the total ownership cost is ₹ 3063.05 per hour. This metric gives a comprehensive look at how much it costs to own and operate the equipment for every hour of usage.
Examples & Analogies
Using the previous car analogy again, if you think of the total placing all the costs together – depreciation (how much value is lost), insurance (protection you pay for), and taxes (government fees) – the total per hour gives you a clear budget for how much you need to set aside every hour you drive it.
