Today, we will discuss how to calculate the Equivalent Annual Cost or EAC. Can anyone tell me what EAC represents in cost analysis?

Noah
Noah

Isn't it the annual cost of owning and operating an asset?

Sarah
SarahInstructor

Exactly! EAC helps us spread out all costs over the equipment's lifespan. Now, for the third year, we start with the purchase price—can you recall how much that was?

Isabella
Isabella

It's 3,500,000 rupees.

Sarah
SarahInstructor

Great! Now, applying the USCRF for year 3 at 15%, which is 0.4380, we can calculate the EAC. Can anyone show me the calculation?

Akash
Akash

It's EAC equals 0.4380 multiplied by 3,500,000, which gives us 1,533,000 rupees!

Sarah
SarahInstructor

Perfect! So the EAC for our purchase price in year 3 is 1,533,000 rupees.

Let's now discuss operating costs. The first-year operating cost was given as 113,200 rupees. How do we find its present worth?

Ananya
Ananya

We use the present worth factor!

Robert
RobertInstructor

Correct! For year 1 with an interest rate of 15%, the present worth factor is 0.8696. Can someone calculate the present worth?

Noah
Noah

It's 98,438.72 rupees!

Robert
RobertInstructor

Excellent! Now, to find its EAC, which uniform series capital recovery factor do we use for year 1?

Akash
Akash

It’s 1.15!

Robert
RobertInstructor

So, how would we calculate the EAC for the operating cost?

Ananya
Ananya

We multiply 1.15 by 98,438.72.

Robert
RobertInstructor

Exactly! The calculation gives us approximately 113,204.53 rupees as the EAC of operating costs for year 1.

Now let's find the EAC of the operating and maintenance cost for year 3. What do we do first?

Isabella
Isabella

We need to calculate the present worth of operating costs for year 3?

Sarah
SarahInstructor

Correct! The given operating cost for year 3 is 538,315.57 rupees. What factor do we use?

Akash
Akash

The capital recovery factor for year 3, which is 0.4380!

Sarah
SarahInstructor

Exactly. Can someone show how to arrive at the EAC for this operating and maintenance cost?

Ananya
Ananya

It’s 0.4380 times 538,315.57, which equals 235,782.22 rupees.

Sarah
SarahInstructor

Great job! You've just calculated the EAC for operating and maintenance costs in year 3.

Session 4: Final Cost Aggregation

Robert
RobertInstructor

Now that we have EAC for the purchase price and operating costs, how do we find the total equivalent annual cost?

Noah
Noah

We add the EAC of purchase price to the EAC of operating costs and then subtract the salvage value!

Robert
RobertInstructor

Exactly! So can anyone tell me what the total EAC would be if the salvage value is taken into account?

Isabella
Isabella

The total would be 1,533,000 plus 235,782.22 minus the resale value.

Akash
Akash

How do we find that resale value?

Robert
RobertInstructor

You would calculate it similarly by converting any future cash inflows of the salvage value into present value and then to EAC.

Ananya
Ananya

Oh! Got it! This helps to identify the economic life of the machine.

Robert
RobertInstructor

Exactly! That brings us to understanding the optimum time to replace the machine based on EAC calculations!
