# Calculating Payback period, NPV and IRR

Caledonia is considering two additional mutually exclusive projects. The cash flows associated with these projects are as follows:

Year Project A Project B

0 -$100,000 -$100,000

1 32,000 0

2 32,000 0

3 32,000 0

4 32,000 0

5 32,000 $200,000

The required rate of return on these projects is 11%.

1. What is each project's payback period?

2. What is each project's net present value?

3. What is each project's internal rate of return?

4. What has caused the ranking conflict?

5. Which project should be accepted? Why?

Solution:

1. What is each project's payback period?

Year Cash Flows Cumulative cash flows

Project A Project B Project A Project B

0 -100000 -100000

1 32000 0 32000 0

2 32000 0 64000 0

3 32000 0 96000 0

4 32000 0 128000 0

5 32000 200000 160000 200000

Payback period is time needed to recover initial outlay.

In case of Project A, it is clear ...
