Example: Saving to Meet a Retirement Goal Sara B. Goode wishes to retire in the year 2022 with personal savings of $500,000 (1997 spending power). Assume that the expected inflation rate in the economy will average 3.75% per year during this period.

Assume that Sara's 1997 salary was $60,000 and that the first deposit took place at the end of 1997. What percent of her yearly salary must Sara put aside for retirement purposes to make her retirement plan a reality?
