Problem Set 1
You are the owner of a large data-services firm and are deciding on the purchase of a new hardware cooling system that you expect will yield $233,300 in cost-savings per year for the next 15 years. The installation of this cooling system will cost $3,000,000.
1. At face value, does this system seem profitable? By how much?
2. Assume that your company uses a discount rate of 6%.
a. What is the Net Present Value (NPV) of this project?
b. How does the NPV of this project change as you assume a higher or lower discount rate? Why?
c. What is the IRR/ROI of this project? d. How much should the yearly cost-savings be in order to break even? i. (hint) use goal-seek/what-if analysis
3. Suppose that you decide to finance the purchase of this system through a loan from the bank. The bank is willing to loan this money over an 8 year term at an interest rate of 4% per year. a. Using a 70/30 debt-to-equity ratio, what is the NPV of this project? i. (hint) calculate the yearly payment using excel function “PMT” b. How does the NPV of this project change if a larger portion is financed through equity (e.g. debt-to-equity ratio of 60/40)? Why?

Pmt | Annual Savings | $233,300 | |||||||||
PV | Present Value of annual savings | $2,265,868 | (Using PV function of excel withRate=6%, Nper=15, Pmt=-233300) | ||||||||
I | Initial Investment | $3,000,000 | |||||||||
NPV=PV-I | Net Present Value of the project | ($734,132) | |||||||||
b | NPV will be lower if discount rate is higher | ||||||||||
NPV will be higher if discount rate is lower | |||||||||||
Because, | |||||||||||
Present Value (PV)of Cash flow: | |||||||||||
(Cash flow)/((1+i)^N) | |||||||||||
i=discount rate , N=Year of cash flow | |||||||||||
If I increases , PV decreases | |||||||||||
If I decreases , PV increases | |||||||||||
For example: | |||||||||||
If discount rate is 1% | 1% | ||||||||||
PV | Present Value of annual savings | $3,234,717 | (Using PV function of excel withRate=1%, Nper=15, Pmt=-233300) | ||||||||
NPV=PV-I | Net Present Value of the project | $234,717 | |||||||||
If discount rate is 10% | 10% | ||||||||||
PV | Present Value of annual savings | $1,774,498 | (Using PV function of excel withRate=10%, Nper=15, Pmt=-233300) | ||||||||
