Assumptions: He maintains a 50% stocks-50% bonds after-tax asset allocation with stocks earning 7% per year including 2% dividend yield and bonds earning 3% interest per year. For the stocks, 20% of capital gains are realized each year with all gains being long term. The original cost basis of assets held in the taxable account is set at the market value. His Primary Insurance Amount for Social Security is $1,667 a month and her Full Retirement Age is 66. So, if he begins Social Security benefits at age 62, he will receive $1,250 per month, while if he waits until age 70 to begin benefits then his benefits will be $2,200 per month with all payments expressed in today’s dollars. All three strategies allocate stocks to the taxable account and bonds to the 401(k) to the degree possible while maintaining the 50% stocks-50% bonds after-tax asset allocation. Based on today’s Tax Code, he will usually be in the 28% tax bracket in retirement. We assumed inflation of 3% per year with all tax brackets, standard deduction, over 65 tax exemption, and personal exemption amount rising with inflation.
