Social Security is a key source of income for millions of retirees. And knowing what the average Social Security check looks like at age 66 can help you plan more effectively. For those born before 1960, their full retirement age (FRA) is between 66 and 67. While those born after 1960 have an FRA of 67. A financial advisor can help you explore different claiming scenarios and build a retirement income strategy tailored to your needs.

How to Determine Your Full Retirement Age

Before deciding when to claim Social Security, it’s essential to know your full retirement age (FRA). This is the age at which you’re eligible to receive 100% of your benefit. Your FRA depends on your year of birth:

  • If you were born between 1943 and 1954, your full retirement age is 66.
  • If you were born between 1955 and 1959, your FRA ranges from 66 and 2 months to 66 and 10 months.
  • If you were born in 1960 or later, your FRA is 67.

If your full retirement age is 67, claiming early at 66 reduces your benefit1 by approximately 6.7%. In other words, you’d receive around 93.3% of your full benefit amount. For many, this smaller reduction feels manageable. It provides steady income but avoids the larger reductions tied to claiming at an earlier age. 

As with any retirement decision, it’s important to consider your full financial picture. This includes life expectancy, overall health, and whether you plan to continue working.

To help you estimate your personal benefit, the Social Security Administration provides month-by-month reduction charts2.
