Should You Take Social Security at Age 62, 67, or 70? A Comprehensive Study Offers a Transparent Answer

In March, the average retired worker brought home $1,913.31 from Social Security. While this might not sound like much, the guaranteed payments provided by America's top retirement program have ensured the financial well-being of our nation's retirees for more than 80 years.

A recently updated analysis from the Center on Budget and Policy Priorities estimates the poverty rate for seniors aged 65 and above would be nearly 39% if Social Security didn't exist. But with eligible beneficiaries taking home a monthly payout, the senior poverty rate is just a shade above 10%.

It's also a program that most retirees lean on to cover at least some portion of their expenses. More than two decades of annual surveys from national pollster Gallup have shown that 80% to 90% of retired-worker beneficiaries rely on their Social Security income to make ends meet.

Getting the most you can out of Social Security may be imperative to your financial well-being during retirement. But in order to do so, you'll first need to understand the nitty gritty of how your benefit is calculated, as well as comprehend just how important your claiming age can be. This can make all the difference in determining whether an early (age 62), middle-ground (age 67), or late (age 70) Social Security retired-worker benefit claim makes the most sense for your situation.

These are the four building blocks of your Social Security check

As I've pointed out in the past, not all aspects of Social Security are black-and-white. For instance, early filers can be penalized by the Social Security Administration (SSA), and some beneficiaries could be taxed on a portion of their payout at the federal level, as well as in 10 states.

But when it comes to calculating your monthly Social Security check, the four building blocks used by the SSA are crystal clear:

  • Work history.

  • Earnings history.

  • Full retirement age.

  • Claiming age.

The first two variables are linked at the hip. When calculating your monthly benefit, the SSA will account for your 35 highest-earning, inflation-adjusted years of earned income (wages and salary but not investment income). As a general rule, if you want a larger Social Security payout, you'll want to earn more, on average, during your decades in the labor force.

Just keep in mind that the SSA also penalizes those who don't work at least 35 years. For every year less of 35 worked, the SSA averages a $0 into their calculation.

The third factor is the one that none of us has any control over. Your full retirement age represents the age you become eligible to collect 100% of your monthly benefit, and it's entirely determined by your birth year. For most of today's workforce, the full retirement age is 67.
