Sheep Ranch Golf Academy is evaluating new golf practice equipment. The "Dimple-Max" equipment costs $137,000, has a 4-year life, and costs $10,600 per year to operate. The relevant discount rate is 9 percent. Assume that the straight-line depreciation method is used and that the equipment is fully depreciated to zero. Furthermore, assume the equipment has a salvage value of $10,100 at the end of the project’s life. The relevant tax rate is 23 percent. All cash flows occur at the end of the year. What is the equivalent annual cost (EAC) of this equipment? (A negative amount should be indicated by a minus sign. Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)



To calculate the **Equivalent Annual Cost (EAC)** of the equipment, we need to consider both the initial investment, operating costs, and the tax implications of depreciation.

Here's a breakdown of the steps involved:

### Step 1: Calculate the annual depreciation
The equipment is depreciated using the straight-line method, so:

\[
\text{Annual Depreciation} = \frac{\text{Cost of Equipment} - \text{Salvage Value}}{\text{Life of the Equipment}}
\]

\[
\text{Annual Depreciation} = \frac{137,000 - 10,100}{4} = 31,725
\]

### Step 2: Calculate the tax shield from depreciation
The tax shield from depreciation is the depreciation amount multiplied by the tax rate:

\[
\text{Tax Shield} = \text{Annual Depreciation} \times \text{Tax Rate}
\]

\[
\text{Tax Shield} = 31,725 \times 0.23 = 7,296.75
\]

### Step 3: Calculate the total annual cash outflows
The total annual cash outflow before taxes is the sum of operating costs. However, we also have the tax shield benefit, so we subtract that from the operating cost:

\[
\text{Net Annual Cash Outflow} = \text{Operating Costs} - \text{Tax Shield}
\]

\[
\text{Net Annual Cash Outflow} = 10,600 - 7,296.75 = 3,303.25
\]

### Step 4: Calculate the present value of the initial investment and salvage value
We discount the initial investment and the salvage value to calculate their net present value (NPV):

\[
\text{NPV of Initial Investment} = \text{Initial Cost of Equipment} - \frac{\text{Salvage Value}}{(1 + \text{Discount Rate})^4}
\]

\[
\text{NPV of Initial Investment} = 137,000 - \frac{10,100}{(1 + 0.09)^4} = 137,000 - 7,124.60 = 129,875.40
\]

### Step 5: Calculate the Equivalent Annual Cost (EAC)
To calculate the EAC, we take the total NPV of the project and convert it into an annualized cost. The formula for EAC is:

\[
\text{EAC} = \frac{\text{NPV}}{\frac{1 - (1 + r)^{-n}}{r}}
\]

Where:
- $ r = 9\% = 0.09 $
- $ n = 4 $ years

First, let's calculate the annuity factor:

\[
\text{Annuity Factor} = \frac{1 - (1 + 0.09)^{-4}}{0.09}
\]

Now, we can calculate the EAC by dividing the NPV of the initial investment by the annuity factor.

I'll calculate the final values for the annuity factor and EAC.The **Equivalent Annual Cost (EAC)** of the "Dimple-Max" equipment is approximately **$43,382.30**.

2. What is the significance of the tax shield in investment decisions?
3. How does the discount rate affect the EAC?
4. Can EAC be applied to non-depreciating assets?
5. How would changing the equipment's salvage value impact the EAC?

**Tip:** EAC is a useful method for comparing different equipment with varying lifespans, as it converts all costs into equivalent annual terms.
