DO THIS PART IN ONE M FILE.

You are a new employee at a hot contractor in the

area. You’ve been given the retirement package and are now trying to figure out various

scenarios for your retirement.

We are going to step through many things to consider, and will

plot and change vario

us scenarios. First there are some baseline conditions

:

-

Your starting pay will be 60,000 dollars and are

guaranteed

a

5% raise every year.

-

Your company does a 6% matching. This means for every dollar you contribute,

they will match that amount, up unti

l 6% of your current salary.

-

The maximum contribution for the next 50 years will stay stagnant at 19000 dollar

.

This mean your personal contributions pre tax will be capped at 19000 dollars.

More than this will come out of your Post

-

Tax income.

-

The 401k i

s assumed 8% annual growth

and will never have a bad year and the stock

market never crashes.

-

Assume for this exercise you start working at 2

3

.

Your goal is to calculate the various scenarios, plot anything required, and answer any questions

as a complet

e sentence in your code.

For any questions that ask for multiple scenarios that are

similar, use matrix math to run all the calculations at once.

All plots should have a descriptive

legend and

using visible connected lines

.

All

text

outputs should be to

a file called

“

Retirement.txt”

and not the terminal.

Separate each part (A

–

F) in your output similar to

“Part A:

“with

a new line

at the end

.

Skip an extra line between each part.

A)

While working these calculations you realize that you also need to cal

culate how much

money you will need. You know that inflation is on average 2% annual. If you know that

without any bills you can comfortably live off of 50,000 dollars in current year dollars,

calculate how much money you will need in your 401k when you

retire at 65 years old.

B)

Plot the following on 1 plot with a proper legend

and state how much money you will have

saved after 30 years.

Assume that you do not clear the 19000 dollar

pre

-

tax

cap

(meaning

you will never contribute more than this in a year)

.

Run all these calculations at once (in a

matrix)

and state weather you will have enough savings from part A.

a.

You will start with

a 5% contribution to your 401k

b.

10%

personal

contribution.

c.

15% personal contribution.

d.

20% personal contribution.

C)

Its known that every 10

-

15 years the stock market takes a tumble. Assume that instead of

this, 20 years into your savings, a massive crash happens, and

you lose 35% of your total

portfolio (as in your 401k at that point drops by 35%). You know that these

things happen,

and are a natural part of the market, and you want to plan for the long game. Plot the

following scenarios and answer weather each will leave you enough savings (from your

calculations in part A)

a.

5% contribution

b.

10% personal

contribution

c.

15% personal contribution

d.

20% personal contribution

D)

You decide early on in your career that you want to follow a passion career as soon as you

can be financially sustainable. You set a goal of age 50 where you will want to stop working

and just let your 401k build naturally. How much do you have to save every year in order to make this happen?

F)

Now run the calculation 1 more time so that you hit the contribution max(the $19000)when you’re 30 years old, but assume that every 10 years your portfolio loses 15% of its value due to market corrections.
