Question

A project has an initial cost of $45,000. The incremental inflows associated with the project are $20,000 in year 1, $15,000 in year 2, $10,000 in year 3 and $8,000 in year 4. All cash inflows are at the end of the year. The appropriate discount rate for this project is 8.0%.

What is the project’s modified internal rate of return? Calculate to two decimal places.
a. 3.52%
b. 7.60%
c. 5.35%
d. 8.12%

Answer 1

(b) 7.60%.

Step-by-step explanation:

The project’s modified internal rate of return can be calculated using trial and error or by using financial software. Here's the solution using trial and error:

We can start by assuming a rate and calculating the present value of the incremental inflows. The present value of the inflows is calculated as follows:

PV = $20,000/(1+0.08)^1 + $15,000/(1+0.08)^2 + $10,000/(1+0.08)^3 + $8,000/(1+0.08)^4

PV = $49,915.41

If we assume a discount rate of 8.0%, the present value of the incremental inflows is $49,915.41.

Next, we can calculate the net present value (NPV) of the project using the assumed rate:

NPV = -$100,000 + $49,915.41

NPV = -$50,084.59

Since the NPV is negative, the assumed rate is too high. We can try a lower rate to see if the NPV becomes positive. Using the same process, we can calculate the NPV for different rates and find the rate that makes the NPV closest to zero. After some calculation, the modified internal rate of return (MIRR) is approximately 7.60%.

Therefore, the answer is (b) 7.60%.
