Initial and Annualized Costs
Unlock Audio Lesson
Today, we are going to learn how to calculate the initial costs of a machine and convert them into annualized costs using a formula. Can anyone tell me what we mean by annualized costs?
Is that like spreading the cost over the years to see how much it costs each year?
Exactly! We use the formula \[ A = I \times \frac{i(1+i)^n}{(1+i)^n - 1} \] where 'I' is the initial cost, 'i' is the interest rate, and 'n' is the number of years. Let's plug in ₹2,89,00,000 for 'I', 0.08 for 'i', and 12.5 for 'n'. What do you get?
When I calculate, I get ₹ 37,41,844.41 per year.
That's correct! Remember this as it is crucial for budgeting in projects. An acronym to recall is 'AC' for Annualized Cost!
So, AC helps us know the yearly financial impact rather than just the upfront cost?
Exactly right! You’ve nailed it. Let’s move on to annualizing the salvage value.
Salvage Value and Its Calculation
Unlock Audio Lesson
Now, let's look at salvage values. Why do we estimate the salvage value in terms of an annual figure?
I guess it helps us understand what we can expect to recover when the machine is no longer used?
Precisely! We convert this future value into annual costs too using the formula \[ A_{salvage} = S \times \frac{i(1+i)^n}{(1+i)^n - 1} \]. So, if our salvage value is 20% of ₹2,89,00,000, how much do we get?
That’s ₹57,80,000. So when I apply the formula, I get an annual cost of about ₹2,85,968.88.
Great job! That means for planning purposes, this is the amount we should factor into our costs yearly. Remember, the concept 'SV' stands for Salvage Value might help!
Depreciation Calculation
Unlock Audio Lesson
Let’s discuss how we calculate hourly depreciation. Who can remind the class what elements come into play here?
We subtract the annualized salvage from the annualized initial cost and then divide by the total hours of operation for the machine!
Right! If we take the annualized cost of ₹37,41,844.41 and subtract ₹2,85,968.88 and divide it by 1600 hours, what do we get as our depreciation cost per hour?
That works out to ₹2,159.92/hr.
Excellent! Remember DS as Depreciation Schedule which can help you relate such concepts in calculations!
Total Ownership Cost
Unlock Audio Lesson
Now let’s get into total ownership costs known as TOC. We include components like depreciation, insurance, and taxes. Can anyone tell me the percentages used for these?
I think it's 2% for insurance and 3% for taxes, both based on the initial cost!
That’s correct! By calculating those into hourly values, we can understand the financial situation better. Who can calculate the hourly insurance?
Using your amounts, it would be ₹36.12/hr.
Awesome job! It’s important to sum these components diligently. Remember ‘TOC’ to stand for Total Ownership Cost!
Operating Costs and Final Calculations
Unlock Audio Lesson
Finally, we estimate our operating costs! Who remembers the fuel consumption factor we mentioned earlier?
It's 0.14 liters per horsepower per hour!
Exactly! If we adjust for our working conditions along with the operating factor, how do we calculate fuel consumption?
By multiplying the operating factor, horsepower, and the fuel consumption factor, we get the fuel consumed.
Well explained! At the end of it, we combine all these operational and ownership costs to derive a total cost per hour. Don't forget 'OC' for Operating Cost as a quick memory tool!

Tire Cost Estimation
This section focuses on estimating the costs related to tires in machinery, specifically using formulas to calculate the equivalent uniform annual costs, salvage values, and other ownership costs. The critical elements include:
- Initial Cost and Annualized Costs: The initial cost is transformed into an annualized cost using a uniform series capital recovery factor. This concept helps in evaluating the total expense incurred per year.
- Formula: \[ A = \frac{I \times i(1+i)^n}{(1+i)^n - 1} \]
- Example given with initial cost of ₹ 2,89,00,000 and an interest rate of 8% over 12.5 years yielding an annualized cost of ₹ 37,41,844.41.
- Salvage Value and Equivalent Costs: The salvage value is also annualized to reflect its future value in yearly terms.
- Formula: \[ A_{salvage} = \frac{S \times i(1+i)^n}{(1+i)^n - 1} \]
- An example shows a 20% salvage value leading to an annual equivalent of ₹ 2,85,968.88.
- Hourly Depreciation: This is calculated by evaluating the annualized initial cost minus the annualized salvage value, divided by the machine's annual usage hours.
- Ownership Costs: Costs such as insurance (2% of initial cost) and taxes (3% of initial cost) are included in the total ownership costs.
- Operating Costs: Fuel and consumable operating costs are estimated based on fuel consumption factors adjusted to the specific operational conditions.
The section concludes with the importance of understanding various factors in tire cost estimation for better budgeting in mechanical projects.

The initial cost is converted into equivalent uniform annual cost, annualized cost we call it as annualized initial cost using uniform series capital recovery factor. The initial cost is nothing but your 2,89,00,000 what you have determined just now after deducting the tire cost, 2,89,00,000 lakh multiplied by your uniform series capital recovery factor, which is nothing but I into (1 + i)^n / ((1 + i)^n - 1). The interest rate you know it is nothing but 8 percent and n is 12.5 years. So you can get the annualized initial cost as ₹ 37,41,844.41 per year.
Detailed Explanation
The initial cost of a project includes all upfront expenditures necessary to start it. In tire cost estimation, this value is adjusted into an equivalent annual cost using a formula that accounts for the time value of money. The formula uses an interest rate (in this case, 8%) and a lifespan (12.5 years). By applying these values, we find that the annualized cost equals ₹ 37,41,844.41. This annualized cost helps in budgeting and financial forecasting over time.
Examples & Analogies
Think of this concept like calculating the annual payment on a car loan. If you buy a car for ₹ 2,89,00,000, instead of paying it all upfront, you spread the cost over several years. The amount you pay each year depends on the car's price, your interest rate, and how long you plan to pay off the loan.
Salvage Value Calculation

So now I need to convert the future salvage value into equivalent uniform annual cost. So the salvage value will be converted into equivalent uniform annual cost. Equivalent uniform annual cost of salvage value = Salvage value x [ i / ((1 + i)^n - 1) ] = 0.2 × 2,89,00,000 × [ ] = ₹ 2,85,968.88/year. How to convert it using uniform series sinking fund factor?
Detailed Explanation
The salvage value is the expected resale value of a project after its useful life. This value is also converted into an annual equivalent using a sinking fund factor, allowing for future cash flows. In this case, the calculation shows that the annualized salvage value is ₹ 2,85,968.88. This information is essential when assessing total project costs as it highlights future benefits.
Examples & Analogies
Imagine selling an old smartphone. When you buy it, you may assume it will sell for some amount in a few years. By estimating how much you’ll earn from that resale, you can include it in your budget planning. Just like with the smartphone, the salvage value of equipment gives you a clearer picture of the overall costs and benefits.
Calculating Hourly Depreciation
Unlock 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 = ₹ 2159.92/hr.
Detailed Explanation
Hourly depreciation summarizes how much value the machine loses each hour of operation. To calculate this, we take the difference between the annualized initial cost and the annualized salvage value, then divide by how many hours the machine is used annually (1600 hours in this context). Understanding depreciation is vital for long-term financial planning as it affects both asset valuation and profitability.
Examples & Analogies
If you own a car, its value decreases as you drive it. For instance, you might find that your car loses ₹ 2,159.92 of value every hour you drive it. This understanding helps you plan your finances better and consider the car's worth compared to its wear and tear.
Costs of Ownership

The insurance percentage is 2% of the initial cost minus the tire cost divided by annual usage of the machine in hours. Therefore, Insurance = 2% × (2,89,00,000) / 1600 = ₹ 361.25/hr.
Detailed Explanation
To estimate the insurance cost associated with the equipment, you calculate it as a percentage of the initial investment (after removing the cost of tires). This provides a clearer picture of ongoing expenses relative to equipment value. The result, ₹ 361.25 per hour, is an essential factor in determining total operational costs.
Examples & Analogies
Consider insurance like a monthly plan for your smartphone. You pay a percentage of its value to protect it from damage. Similarly, with heavy equipment, you pay a fraction of its value to safeguard against potential losses, helping to manage overall expenses effectively.
Accounting for Taxes

The tax percentage is 3% of the initial cost minus the tire cost divided by hourly usage of the machine in a year. Tax = 3% × (2,89,00,000) / 1600 = ₹ 541.88/hr.
Detailed Explanation
Just like insurance, taxes are accounted for as a percentage of the investment in the equipment. Calculating taxes on the adjusted initial cost gives us an hourly cost applicable to owning and operating the equipment. The hourly tax estimate of ₹ 541.88 serves as part of the overall operating expenses to ensure that all costs are accounted for in the budgeting process.
Examples & Analogies
Taxes can be likened to a small fee you pay regularly based on the value of your property. For your home or vehicle, the government charges a percentage of its value each year, and understanding this cost helps you budget effectively for the future.
