In 1995, workers said they expected to retire at age 60 on average. In 2012, the average worker expects to retire at 66.
Benefits of postponing retirement:
First, you can nearly double your annual Social Security payouts if you delay retirement from age 62 to 70.
In addition, your extra 8 years of income play double duty. During those 8 years, you continue to build your nest egg through continued savings rather than drawing on it for living expenses.
