# Brent's Finances

## Scenario #1

24 year old Brent has no college loans, but does have an income of \$50,000 and a \$23,000 car with a 6.5% 5 year car loan.

## Salary per Month After Tax

From annual: 50,000-(5,156.25+(12550*.25)=\$41,706.25

Per month: 41,706.25/12= \$3475.52

## Car Payment

23,000=R((1-(1+(.065/12))^-60)/(.065/12))

23,000=R(51.10867958)

R=\$234.79

## Monthly Budget

Insurance (Car and health, respectively): 95.58+196=\$291.58

Car Payment: \$234.79

Food: \$311.60

Utilities: \$367.96

Cell Phone: \$73

Gas(comes from the two websites above)/entertainment: \$358.50

Other: \$100

Total Monthly Expenses: \$1737.47

## Budget for House

Possible Monthly Budget: 3475.52-1737.43=\$1738.09

Mortgage Interest Rate: 5.25%

What can I afford?: PV=1738((1-(1+(.0525/12)^(-12*30)))/(.0525/12))

PV=(1738.09(181.0925925)

PV= \$314,755.22

Brent should buy a house that costs \$300,000 so he won't max out his budget.

## A 30 Year Fixed Rate Loan

According to Bank of America's website, the interest rate for a house that costs \$300,000 at a 30 year fixed rate is 3.750%. This was with a 20% down payment. (In other words, \$60,000 was the down payment.) This information was found on February 16th, 2016. Using this information, you find the minimum monthly payments for a \$300,000 house.

300,000-60,000=R((1-(1+(.0375/12))^-12*30)/(.0375/12))

R= \$1,111.48

## Increasing the Minimum Monthly Payment by 15%

The minimum monthly payment is \$1,111.48, so if it was increased by 15%, it would be about \$1,278.19. To find how much time is saved, you would plug in the numbers in the PV formula and solve for t.

240,000=1278.19((1-(1+(.0375/12))^-12*t)/(.0375/12))

T=22.69

It would take around 22 years and 8 months with the increase in monthly payments, so it would save 7 years and 4 months.

To find how much money is paid with the original payment, you multiply it by 12 (the number of months in a year) and 30 (the total amount of years Brent will be paying). As a result, you get \$400,132.80.

1111.48(12)(30)=\$400,132.80

To find how much money is paid with the increased payment, you multiply it by 12 (the number of months in a year) and 22 (the amount in years Brent is paying). You must then add \$1,278.19 (the payment) multiplied by 8 (the number of months not included in the amount of years.

(1278.19(12)(22))+(1278.19*8)=\$347,667.68

To find how much is saved, you subtract the new value from the old:

400,132.80-347,667.68=\$52,465.12

Brent would same 7 years and 4 months and \$52,465.12 if he increased his minimum monthly payment by 15%.
