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 information do I need to use a Social Security calculator effectively?
To use a Social Security calculator effectively, you will need information about your earnings history and your expected future earnings. Specifically, you should have your past annual earnings readily available, ideally from your Social Security statements or tax returns. If you are using a calculator that projects future benefits, you will need to estimate your income for the years between now and when you plan to claim benefits. Understanding your full retirement age based on your birth year is also important, as calculators often ask for your desired claiming age to show benefit adjustments.
