Chris is planning for his retirement. He is currently 46 and plans to retire in 21 years, at age 67. He expects then to live an additional 20 years, until age 87. He expects inflation to average 3% per year. Based on his assumptions about inflation and Social Security, and his desired Wage Replacement Rate, he believes he will need $240,000 per year in income from his investments (in nominal dollars) in the first year of his retirement. He believes he can earn a nominal return on his retirement investments of 8% per year before retirement, and 6% per year after retirement. Use the Annuity method with the Dalton approach. How much does he need to accumulate by retirement, in nominal dollars?
