Your monthly Social Security retirement benefit is calculated using your highest 35 years of inflation-adjusted earnings, a specific formula, and your age when you begin receiving benefits.
The Social Security Administration (SSA) determines your retirement benefit by first calculating your average indexed monthly earnings (AIME) over your highest 35 years of earnings. These earnings are adjusted for inflation to reflect their value in today's dollars. Then, a formula is applied to your AIME to arrive at your primary insurance amount (PIA), which is the benefit you would receive at your full retirement age. Finally, your benefit amount is adjusted based on whether you start receiving benefits before, at, or after your full retirement age.

What factors influence the accuracy of my retirement benefit estimate?
The accuracy of your Social Security retirement benefit estimate depends on several factors, primarily your reported earnings history and your assumed future earnings. The Social Security Administration uses your actual earnings up to the present and projects your earnings until you claim benefits. If your actual earnings differ significantly from these projections, your final benefit amount will vary. Estimates are most accurate for individuals who have consistently worked and earned at or above the Social Security taxable maximum throughout their careers. Unexpected changes in employment, income, or claiming age can also affect the final amount.
