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.

How does inflation indexing affect my Social Security benefit calculation?
Inflation indexing is a crucial part of the Social Security benefit calculation because it ensures that your past earnings are valued in terms of today's dollars. Wages generally rise over time due to inflation and increases in productivity. The indexing process adjusts your earnings for each year up to age 60 to reflect the general wage growth that occurred during those years. This means that earnings from earlier in your career are increased to reflect their approximate value when you reach age 62, preventing older earnings from being unfairly devalued. Without indexing, your average earnings would be significantly lower, resulting in a smaller monthly benefit.
