Here's the Average Social Security Benefit at Age 66

For most Americans, Social Security plays a key role in fortifying their financial foundation during retirement. More than two decades of annual surveys from Gallup have shown that between 80% and 90% of then-current retirees count on their guaranteed monthly benefit to cover at least some portion of their expenses.

A separate study from the Center on Budget and Policy Priorities found that, as of 2022, Social Security payouts were responsible for pulling approximately 22.7 million people above the federal poverty line, including 16.5 million 65 or older.

Put bluntly, it's important to get as much as you can out of America's top retirement program. But to do so, you first need to understand the nuts and bolts of how your benefit is calculated, as well as get a firm grasp on just how much your claiming age can swing the payout pendulum.

Knowing these details can help answer the age-old question of whether or not a middle-ground claiming approach at 66 is a smart choice.

These four components are used to calculate your monthly Social Security check

In some respects, Social Security can be a complex or downright confusing program. As I've previously pointed out, it can surprise some folks to learn that a portion of their Social Security benefits can be taxed at the federal level, and possibly in 10 states, depending on their provisional income.

But when it comes to calculating your monthly Social Security check, four simple components are taken into account by the Social Security Administration (SSA):

  • Earnings history

  • Work history

  • Full retirement age

  • Claiming age

The first of these two items go hand in hand. When calculating what you'll receive each month in retired-worker benefits, the SSA takes into account your 35 highest-earning, inflation-adjusted years. Keep in mind that only earned income -- such as wages and salary, not investment income -- count toward this calculation.

And the SSA will average in a $0 for every year fewer than 35 that you've worked. If you have any hope of maximizing your monthly and/or lifetime payout, you'll want to work 35 years at minimum, if not longer.

The third element is your full retirement age, which represents the age you're eligible to receive 100% of your monthly benefit. Your full retirement age is determined by your birth year and represents the only factor of the four that you can't control.

The fourth ingredient used to calculate your Social Security check, and the one with the greatest potential to alter your financial future during retirement, is your claiming age. While retired workers can begin receiving their monthly benefit as early as 62, the program strongly encourages future retirees to exercise patience.
