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 they have saved $100,000 for retirement and continue to save $7,500 annually (at the end of each year). If they can earn 7% on their investment portfolio, and inflation is 3%, how many years would their total funds saved at retirement last if they wanted to retire with a 70% WRR?
