1. Equivalent Annual Cost Calculation

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 𝟎.𝟏𝟓(𝟏+𝟎.𝟏𝟓)𝟑 USCRF = = = = 0.4380 (𝟑𝟓𝟎𝟎𝟕𝟎𝟎,𝟎.𝟏𝟓,𝟑) (𝟏+𝒊)𝒏−𝟏 (𝟏+𝟎.𝟏𝟓)𝟑−𝟏 EAC = 0.4380 × 35,00,000 = 15,33,000 rupees.

To calculate the Equivalent Annual Cost (EAC) for a purchase price, we apply the formula involving the Uniform Series Capital Recovery Factor (USCRF). In this case, for year 3, the USCRF is calculated based on the interest rate (15%) and the number of years (3). The EAC is obtained by multiplying the USCRF by the purchase price (3,500,000 rupees), yielding an EAC of 1,533,000 rupees for the third year. This process is essential for businesses to evaluate the annual cost of an investment over its lifespan.

Imagine you buy a new car for 35,00,000 rupees. If you want to figure out how much that car costs you every year over a period of three years, you'd divide the total cost by how many years you will use it and account for interest on that cost. This is similar to how you figure out what the EAC is - it's like breaking down the total cost into manageable yearly expenses.

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.

To find the equivalent annual cost of operating and maintenance costs, we first determine the present worth of these costs. For instance, if the operating and maintenance cost is 113,200 rupees at the end of year 1, we need to convert it to the present value (t=0) using the present worth factor for the specified interest rate and time. This entails multiplying the future cost by the present worth factor, yielding a present worth value that serves as the basis for further calculations.

Think of it like saving money for a future trip. If you plan to spend 1,13,200 rupees next year, to understand how much that would be worth today, you'd apply a present value concept. It's like how much you need to save today, given that money can earn interest over time, to have the same amount next year.

Now you add the cumulative, so find the cumulative operating and maintenance cost. So, now, next thing is we are going to find the equivalent annual cost of the present worth of the operating and maintenance cost.

Once the present worth of operating and maintenance costs is established, we proceed to combine these values to derive a cumulative total. This total is then essential for calculating the equivalent annual cost over the lifespan of the equipment. The equivalent annual cost allows us to understand what portion of our annual budget should be allocated toward these operating costs in the future.

If you've had several expenses for your car maintenance over several years - like oil changes, new tires, etc. - you would total them together to understand how much that car costs you to maintain annually. This totals into a cumulative cost that can be used for future budgeting.

Now we are going to find the A, equivalent A for this P, so how to do that? A = P × USCRF. So, this factor you multiply it by the operating and the maintenance cost present value that is 98,438.72.

After determining the present worth of operating and maintenance costs, the next step is to convert that total into an equivalent annual cost using the USCRF. This involves multiplying the present worth value (98,438.72 rupees) by the USCRF corresponding to the interest rate and the period under consideration. This effectively spreads the total present worth cost over the desired timeframe, giving a clearer picture of annual financial expectations.

Consider your favorite subscription service that charges a one-time fee for a year but provides monthly benefits. To understand how much you effectively pay each month, you take the total fee and divide it by the number of months, thus giving you a clear monthly cost reflecting the annual total.

Now let us find the equivalent annual cost of the resale value, that is your salvage value. So, now we are going to calculate the present value of the resale value.

To compute the equivalent annual cost of the resale (or salvage) value, we first need to determine its present value. This involves applying the present worth factor similarly as before to the expected resale value at the end of its useful life. Once we have the present worth, we can then convert that value to an equivalent annual cost using the same approach we previously applied.

If you decide to sell an old phone, the money you receive is your resale value. But depending on when you sell it, its value may differ. Understanding its current worth helps you assess how to factor that into your overall budget when planning to buy a new phone.

Now you can find the total cost. So, how to find the total cost? You are supposed to add the purchase price and the operating and maintenance cost, your salvage value is in flow cash inflow, so you subtract it.

The final step involves summing the equivalent costs calculated throughout the previous sections to derive the total equivalent annual cost. This total aligns the investment and expected operational expenses while factoring in the resale value as a cash inflow, giving a holistic view of the economic implications of the investment.

It's like preparing a yearly budget where you account for all your spending and income. You list your fixed costs (like rent or car payments), add additional costs (like groceries), and subtract any expected income (like bonuses from work) to ensure you understand your financial situation over the year.
