Please explain with the excel working and
formulas.
Assume that today is April 1, 2022. Natasha Kingery is 30 years
old and has a Bachelor of Science degree in computer science. She
is currently employed as a Tier 2 field service representative for
a telephony corporation located in Seattle, Washington, and earns
$38,000 a year that she anticipates will grow at 3% per year.
Natasha hopes to retire at age 65 and has just begun to think about
the future. Natasha recently inherited $75,000 from her aunt. She
invested this money in 30-year Treasury Bonds. She is considering
whether she should further her education; she would use her
inheritance to pay for it. She has investigated a couple of
education options and is asking for your help as a financial
planning intern to determine the financial consequences associated
with each option. Natasha has already been accepted to both
programs and could start either one soon. One alternative that
Natasha is considering is attaining a certification in network
design. This certification would automatically promote her to a
Tier 3 field service representative in her company. The base salary
for a Tier 3 representative is $10,000 more than what she currently
earns, and she anticipates that this salary differential will grow
at a rate of 3% per year as long as she keeps working. The
certification program requires the completion of 20 Web-based
courses and a score of 80% or better on an exm at the end of the
course work. She has learned that the average amount of time
necessary to finish the program is one year. The total cost of the
program is $5000, due when she enrolls in the program. Because she
will do all the work for the certification on her own time, Natasha
does not expect to lose any income during the certification.
Another option is going back to school for an MBA degree. With an
MBA degree, Natasha expects to be promoted to a managerial position
in her current firm. The managerial position pays $20,000 a year
more than her current position. She expects that this salary
differential will also grow at a rate of 3% per year for as long as
she keeps working. The evening program, which will take three years
to complete, costs $25,000 per year, due at the beginning of each
of her three years in school. Because she will attend classes in
the evening, Natasha doesn't expect to lose any income while she is
earning her MBA if she chooses to undertake the MBA
Use this interest rate of 2.44% as the discount rate for the
remainder of this problem.
Q2. Create a timeline in Excel for her current situation, as
well as for the certification program and MBA degree options, using
the following assumptions:
Q3. Calculate the present value of the salary differential for
completing the certification program. Subtract the cost of the
program to get the NPV of undertaking the certification
program.
Q4. Calculate the present value of the salary differential for
completing the MBA degree. Calculate the present value of the cost
of the MBA program. Based on your calculations, determine the NPV
of undertaking the MBA.
Q5. Based on your answers to Questions 3 and 4, what advice
would you give to Natasha? What if the two programs are mutually
exclusive? (That is, if Natasha undertakes one of the programs,
there is no further benefit to undertaking the other program.)
Would your advice be different?
