Bob and Martha, a married couple, are both 42 years old and want to retire when they reach age 65. After careful calculation, they have determined they could live comfortably on $65,000 a year in todays dollars when they retire. They are eligible to receive $2,000 in combined monthly Social Security benefits and $1,600 combined monthly income from their company pensions. They are comfortable assuming an inflation rate of 3%, an after-tax rate of return of 5% on their invested assets, and a life expectancy to age 90. Their combined federal and state income tax bracket is 33%. Carry real return to nearest hundredth. Using the example from the module reading and lecture, approximately how much is their Retirement Savings Goal (lump sum of personal savings needed at start of retirement)?
