How Social Security Calculates Your Monthly Retirement Benefits

Answer from Seniorlifeinsights

Social Security retirement benefits are calculated using your highest 35 years of indexed earnings, not just your recent income.

The Social Security Administration (SSA) determines your monthly 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 over time. Then, a formula is applied to your AIME to arrive at your primary insurance amount (PIA), which is the benefit you would receive if you start claiming at your full retirement age. Finally, your benefit is adjusted based on the age you choose to begin receiving payments.
