John, age 42, has come to you for help in planning his retirement. He works for one of the big 8 accounting firms as a financial planner for their high net worth clients, where he earns $240,000. Alex would like to retire at age 67. He has consistently earned 8.5% on his investments and inflation has averaged 2%. Assuming he is expected to live until age 93 and he has a wage replacement ratio of 65%, how much will Alex need to have accumulated as of the day he retires to adequately provide for his retirement lifestyle?

Referring to this scenario, how much more would John need to have at the beginning of retirement to have the same purchasing power at his death as at the beginning of retirement? Begin/End? N? I? PV? PMT? FV?
