6.  If the Hall’s want to have as much of an after-tax income when they retire as they currently have, and assuming they live until they are 80 years old, how much money should they set aside each month so as to have enough money accumulated in their retirement nest egg?

7.  If the Hall’s continue paying the minimum 3% on their credit card debt each month, how long will it take them to pay it off and how much total interest will they have paid? If you were Dan, what would you advice them to do?

Credit Card Balance 10,000Interest Rate 15.99%

3% Minimum Payment -300Number of months required to pay off debt 44.367051

Total Interest Paid 3310.1153

Dan's Advice1. Continue paying minimum on:

Car ($221.58)College Loans ($527.80)

2. Live cheap for the next few months and pay maximum available on credit card debt

Available income after rent, car payment, and college loan payments = $2,550.62 They should be able to clear the debt within 6 months.

3. Then start putting money away towards the house down payment, child's education, and retirement

Down payment ($1,326.92)Child's education ($319.28)Retirement plan ($1,044.04)

Note...They may have to save a little less than the calculated amount each month…($2,690.23)

4. Within 24 months, their college loans will be paid off, the deposit towards the down payment will have ended, and they could work towards paying off their mortgage as quickly as possible.
