Did you know that a person retiring at age 65 spends an average of 18 years in retirement? Experts estimate that you'll need 70-80% of your pre-retirement income—lower earners will need 90 percent or more—to maintain your standard of living when you stop working. This is based on the assumption that you'll cut out many of your current expenses, like commuting costs, when you retire.
