Your new clients, the Smiths, have 30 years until retirement. Once they retire, they expect to live for another 35 years and believe they will need $90,000 per year at the beginning of each year in todays dollars. They expect Social Security to provide them with $15,000 per year, again in todays dollars. You estimate that you can earn 8% annually on their investments, and that inflation will average 2% per year. Assuming they have already saved $125,000 towards their retirement, how much do they need to save at the end of each year over the next 30 years to fund their retirement spending needs?
