Assume you have a 35-year old client who makes $75,000, wants to retire at 65, and expects to live until they are 90 years of age. Further assume the present value of their expected Social Security benefit is $15,000. If they can earn 7% on their investment portfolio, and inflation is 3%, how much would they have to save per year (end-of-year payments) in order to retire with a 70% WRR?
