Today we'll start with calculating the equivalent annual cost for our machine's purchase price. Who remembers the formula we use for this?
Is it using the USCRF?
Exactly right! The formula is EAC = USCRF times the purchase price. In our case, we’re using a purchase price of 3,500,000.
And what does USCRF stand for?
Good question! It stands for Uniform Series Capital Recovery Factor. It's important since it helps us convert future costs into equal annual costs. Let’s see if anyone can calculate the USCRF for us!
The USCRF for our case is 0.4380!
Perfect! Now, multiplying 0.4380 by 3,500,000 gives us our equivalent annual cost.
That would be around 1,533,000 rupees!
Yes! Now we have a better understanding of what the EAC tells us about our machine's financials. Remember, EAC helps in making better equipment replacement decisions.

Now let’s talk about operating costs! Why is it important to calculate the present worth of operating costs?
So we can understand their impact over time?
Exactly! It helps in comparing initial costs with future expenses. So, how do we find the present worth of an operating cost of 113,200?
We use the present worth factor, right?
Correct! For an interest rate of 15% over one year, the present worth factor is 0.8696. Can someone calculate the present worth for me?
It will be approximately 98,438.72 rupees!
Excellent! This present worth will help us compute the equivalent annual cost for the operating costs.
And then we continue for different years, right?
Exactly! Each year’s operating cost is analyzed similarly.
Evaluating Salvage Value
🔒 Unlock Audio Lesson

Let’s look into salvage value. Why do you think the salvage value is considered in our calculations?
Because it’s a future cash inflow?
Right! It offsets some costs. When calculating the salvage value, how do we begin?
We find its present worth using the same present worth factor?
Exactly! For a resale value of 3,150,000, applying the present worth factor of 0.8696 gives us a present worth of about 2,739,240.
Then we find EAC for salvage value too?
Correct! We convert that into EAC just like other costs.
Calculating Total Equivalent Annual Cost
🔒 Unlock Audio Lesson

Finally, let’s compute the total EAC. Can anyone tell me how we calculate the overall total?
We add the EAC of purchase price with operating costs and subtract salvage value EAC.
Yes! So if our values are 4,025,000 for purchase price EAC, 1,13,204.53 for operating costs, and 3,150,126 for salvage value, what do we get?
It should be around 988,078.53 rupees!
Right! And can someone summarize why we do this?
To determine the optimal cost for maintaining our machine, while knowing when to replace it!
Great summary! Understanding these costs is crucial for effective management of our assets.

So, now we have to find the equivalent annual cost for the third year of the purchase price 3500000
for year 3,
A_i(1+i)^n \USCRF = \frac{0.15(1+0.15)^{3}}{(1+i)^{n}-1} = 0.4380
EAC = 0.4380 × 35,00,000 = 15,33,000 rupees
So like this you are going to calculate for all the years.
Detailed Explanation
In this chunk, we are calculating the equivalent annual cost (EAC) of a purchase price of 3,500,000 for the third year. We use the formula for the Uniform Series Capital Recovery Factor (USCRF), which helps to determine how much of the total cost we need to account for on an annual basis. Here, we calculate the USCRF for year 3 with an interest rate of 15%, yielding a factor of 0.4380. We then multiply this factor by the purchase price of 3,500,000 to find that the EAC for the third year is 1,533,000 rupees. This process needs to be repeated for all years to understand their financial implications.
Examples & Analogies
Imagine you bought a car for 3,500,000 rupees. If you want to understand how much you need to save annually to cover the cost of the car over its lifespan (let’s say 10 years), you'd use similar calculations. By deciphering how much you're 'spending' each year, you can better manage your finances, just like understanding the EAC helps in budgeting for your purchases.

Now let us find the equivalent annual cost of the operating and the maintenance cost. So, how to find the equivalent annual cost let us go back to the cash flow diagram. So, this 1,13,200 is operating and maintenance cost at the end of year 1.
Detailed Explanation
This chunk introduces how to calculate the present worth of operating and maintenance costs, starting with identifying an operating cost of 113,200 rupees at the end of year 1. The first step is to convert this future cash flow into present value (P), which allows us to assess its worth in today's terms. To do this, we apply the present worth factor, which is calculated based on the interest rate and time period until year 1. By establishing this present worth, we can then use it to calculate its equivalent annual cost.
Examples & Analogies
Think of when you have to service your car. If a service costs you 113,200 rupees after one year, you need to consider how much you should set aside today to pay for that service later. Just as you'd figure out savings for the car service cost in advance, this financial analysis does the same for operating costs.

So, we are going to find the present worth of 1,13,200 that is your operating cost. So, you need to find P for the known F, i, n,
P.W = \frac{P}{(1+i)^{n}} = 0.8696
Present worth value = 0.8696 × 1,13,200 = 98,438.72 rupees
Detailed Explanation
In this chunk, we calculate the present worth (PW) of the operating cost of 113,200 rupees for the first year. We determine the present worth factor given the future value, interest rate (15%), and period (1 year), resulting in a factor of 0.8696. By multiplying this factor with the future cost, we determine the present worth value to be 98,438.72 rupees. This conversion is crucial as it standardizes future costs to today’s value, making it easier to budget and plan financially.
Examples & Analogies
Consider saving for a vacation. If you plan to spend 113,200 rupees next year, you'd need to think about how much you should save today, considering the interest you could earn from that amount. This is akin to finding present worth; it helps in understanding the current equivalence of future expenses.
