But now, depending on the year you were born, you will not reach your full retirement age until between 65 and 67. People born in 1937 or earlier reach "full retirement age" at 65. From 1938 on, it rises gradually to age 67.
You even have an option of delaying your benefits past your full retirement age, thereby locking into an even higher monthly check. If you plan on working during retirement, you may want to delay benefits, as your earnings could negatively affect the amount. However, there are also instances where taking early benefits will most likely pay off.
If you start collecting at the earliest opportunity -- age 62 -- you'll receive a permanently reduced benefit, but you could make out better overall if you live long enough to offset the reduction.
If you wait until your full retirement age, you can collect 100 percent of your benefit.
Determining which option is right for you depends on a number of variables, including your life expectancy, financial picture and -- according to economists at the Center for Retirement Research -- gender and marital status.
Put it off
Generally, financial advisers say it's best to postpone Social Security benefits as long as possible, at least until your full retirement age as determined by the Social Security Administration, or SSA.
Early Social Security can cost you
If your full retirement age is 67, your Social Security benefit is reduced by:
- About 30 percent if you start collecting at 62.
- About 25 percent if you start collecting at 63.
- About 20 percent if you start collecting at 64.
- About 13.3 percent if you start collecting at 65.
- About 6.7 percent if you start collecting at 66.

"Social Security is like longevity insurance," says Brent Neiser, a Certified Financial Planner and director of the National Endowment for Financial Education. "It's a stream of payments that will not stop throughout your life, so delaying your benefits to keep those payments as large as possible forms a helpful base to your retirement plan."
In fact, he notes, those who undersaved for retirement should use whatever means possible to postpone their Social Security benefits until after their retirement age to help boost future income.
If your full retirement age is 66, for example, you'll receive 108 percent of your monthly benefit by delaying Social Security until age 67.
