Introduction to Equivalent Annual Cost
Unlock Audio Lesson
Today, we're going to talk about Calculating the Equivalent Annual Cost, or EAC. Can anyone tell me what the EAC represents?
Isn’t it the annual cost of owning and operating an asset?
Exactly! The EAC helps us to compare costs across different projects by translating all future costs into a single annual figure.
But how do we calculate that?
We'll go step by step, starting with the Purchase Price EAC. We need to use the Uniform Series Capital Recovery Factor, or USCRF, for that. Let's denote it as USCRF.
What does that factor do?
Great question! The USCRF translates a lump-sum amount into equal annual payments over a specified period.
So, if we have a higher USCRF, it means our annual cost is higher?
Not necessarily. The EAC also depends on the total investment and interest rate. Let’s now calculate EAC for Year 2.
So, to summarize, the EAC is crucial for financial planning in projects, allowing comparisons across investments.
Calculating EAC for Purchase Price
Unlock Audio Lesson
To calculate the EAC for the purchase price for Year 2, we need to apply the purchase price alongside the USCRF.
So what is the purchase price we are using here?
The purchase price is Rs. 3,500,000 and the calculated USCRF for Year 2 is 0.4380.
So how do we multiply those?
Right! The calculation will be as follows. EAC = USCRF × Purchase Price, which is equal to 0.4380 multiplied by 3,500,000.
What do we get as a result?
You would find it gives us EAC at Rs. 1,533,000!
That's a large sum! We need to consider this in our budgeting.
Absolutely! Let's move on to cover operating costs.
Discovering Operating Costs EAC

Next, we will calculate the EAC of the operational and maintenance costs and how to translate future costs to present worth.
What should we do first?
We start by finding the present worth of the operational cost. Let's say it is Rs. 113,200 for Year 1.
How do we convert that to present worth?
We apply the present worth factor, which is 0.8696 here. So the present worth would be 113,200 times 0.8696.
That sounds simple enough. What comes next?
Next, we calculate equivalent annual cost using the same USCRF approach we discussed. We then apply this to the present worth we just calculated.
So, once we have everything, we add up the total costs to see how it impacts the EAC.
Exactly! Making sense of all annual costs gives us the total EAC, which is vital for decision-making.
Final Calculations and Cumulative Costs
Unlock Audio Lesson
Finally, it's time to summarize how we accumulate equivalent costs?
We need to assess both EAC for purchase and the operating costs, right?
Correct! So our total EAC would be the sum, including any salvage values as an inflow.
How does that affect our long-term budgeting?
It ensures we are not overspending and can give insights into when it’s preferable to replace equipment or continue operation.
Once we identify the economic life, we can make informed decisions about our investment.
Exactly! Understanding these calculations gives you a solid grasp of financial management for projects.

Detailed Summary
This section delves into the calculation of the Equivalent Annual Cost (EAC) for Year 2 of a project involving a capital investment. The EAC is crucial in determining the yearly cost of an investment, enabling comparison across different alternatives in project management.
Key Steps Covered:
- Calculating EAC of Purchase Price: For Year 3, the given purchase price is Rs. 3,500,000 with a Uniform Series Capital Recovery Factor (USCRF) of 0.4380, resulting in an EAC of Rs. 1,533,000.
- Finding EAC of Operating and Maintenance Costs: This involves translating future operating and maintenance costs to present worth and then calculating EAC. The present worth is found using the present worth factor, followed by the capital recovery factor to derive the equivalent annual cost.
- Example Calculation: An operating cost of Rs. 113,200 for Year 1 has a present worth of Rs. 98,438.72 after applying a factor of 0.8696. The corresponding EAC for year 1 calculates to Rs. 113,204.53.
- Calculating Year 2 Costs: For Year 2, the present worth of operating costs is Rs. 312,793.07, leading to an EAC of Rs. 192,399.02.
- Cumulative Costs: Equivalent annual costs are accumulated and combined with the purchase price to get total EAC. The significance of the cumulative costs helps in identifying the economic life cycle of the investment.
This thorough examination of EAC allows for a strategic financial assessment of investments over multiple years, assisting decision-makers in evaluating the operational efficiency and feasibility of their capital assets.

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. Now you convert it into t = 0, how to convert it into t = 0, find the present worth? So, find the present worth of 1,13,200, so that is a first step. Once you find the present worth of 1,13,200 then you can find it is equivalent annual cost using uniform series capital recovery factor.
Detailed Explanation
To calculate the equivalent annual cost of operating and maintenance costs, the first step involves determining the present worth of those costs. The cash flow diagram indicates that the operating cost at the end of year 1 is 1,13,200. We need to convert this future cash flow into its present worth (t=0) using the appropriate formula.
Examples & Analogies
Think of it like converting future payments (like an annuity) into today's money for better budgeting. Imagine you're promised a birthday gift of $1,000 next year. To know how much that gift is worth today considering you could invest that money instead, you would calculate the present value.

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 = 1 / (1 + 0.15) = 0.8696. This present worth factor you multiply it by the operating and maintenance cost Present worth value = 0.8696 × 1,13,200 = 98,438.72 rupees.
Detailed Explanation
Next, we use the present worth formula, where the relevant factor (0.8696) corresponds to a discount rate of 15% over one year. By multiplying this factor by the total operating cost, we determine the present worth of the future operating costs at year 1.
Examples & Analogies
It's akin to calculating how much a future rental payment of $1,000 is worth today. If you know the rent will be due at a higher interest rate, you'd find it's actually worth less today, which is what the present worth calculation helps you determine.

So, like this you are going to calculate the present worth of all the operating and maintenance costs. After calculating multiple costs, you need to add them up to determine the total or cumulative operating and maintenance cost, which will be used for the next calculations.
Detailed Explanation
After finding the present worth for all operating costs across different years, the next step is adding these amounts to get a clear picture of total costs incurred so far. This cumulative figure is important as it impacts the final equivalent annual cost that you'll calculate next.
Examples & Analogies
Consider this as collecting receipts over time – each receipt represents spending in a different month, but at the end of the year, you want a total – knowing whether you're above or below your budget.

So now we are going to calculate the equivalent annual cost of the present worth of operating and maintenance cost for year 2. So, it is nothing but your know the present worth of the operating and maintenance cost, you are going to find the A for the known P, i, n. USCRF = 0.6151, EAC of O&M cost for year 2 = 0.6151 × 3,12,793.07 = 1,92,399.02 rupees.
Detailed Explanation
At this stage, we are calculating the equivalent annual cost for the second year based on the present worth determined previously. By utilizing the uniform series capital recovery factor (USCRF), we convert this value into an annual payment equivalent.
Examples & Analogies
Imagine you bought a car but calculated out exactly how much you’d need to pay monthly to own that vehicle throughout its life. Instead of lump sums, you want manageable monthly payments that reflect overall costs.
