3 Essential Social Security Facts Most Americans Don't Know

Social Security is one of the primary sources of income for most retirees -- yet the majority of Americans are pretty clueless about exactly how Social Security benefits work. Unfortunately, missing out on some fundamental knowledge about the Social Security program could end up affecting how much you're able to receive in benefits. You don't want to inadvertently cut your Social Security income or make choices based on incomplete info, so it's important you find out the basics.

In particular, there are three essential facts that future retirees need to know -- but don't. According to a Nationwide survey, 76% of older adults don't know what their full retirement age is; 52% don't know that Social Security provides income for life; and 60% don't know that Social Security is protected against inflation. You no longer have to be one of the majority of Americans who don't know these key facts, as you can read in detail below about how this essential information affects you.

What is full retirement age, and why does it matter?

When you claim benefits, the age at which you start receiving Social Security affects the amount of income you'll get.

  • If you claim at the age deemed your full retirement age, you'll receive your primary insurance benefit. Your primary benefit amount is calculated based on your average wages over your highest 35 years of work, adjusted for inflation. If you retire before your FRA, the primary benefit you'd otherwise receive is reduced by 5/9 of 1% for each of the first 36 months early, and by an additional 5/12 of 1% for each additional month before your FRA that you receive benefits.

  • Claiming after your FRA, on the other hand, can result in earning delayed retirement credits that increase the monthly benefit you get by 2/3 of 1% per month for each month you delay until age 70.

Full retirement age varies depending on your birth year, but retiring either before or after it can have a huge impact on your benefits. A person who retires at 62 instead of a full retirement age of 67 will see a 30% reduction in monthly benefits, for example. And the reduction or increase in benefits affects you for the entirety of retirement -- if you claim early, benefits don't go up once you hit your FRA.

The chart below will show you what your FRA is so you'll know when you can retire with full benefits -- and you can also check out this chart to see how claiming early could potentially affect your income. Knowing your full retirement age -- along with how retiring earlier or later will affect your benefits -- can help you make a fully informed choice about the best age to start receiving Social Security.
