1. What is Social Security Benefit Calculation?

The Social Security benefit calculation determines your monthly retirement benefit based on your Primary Insurance Amount (PIA), claiming age, and adjustments. The PIA is based on your highest 35 years of earnings, and the final benefit is adjusted based on when you claim relative to your Full Retirement Age (FRA).

2. How Does the Calculator Work?

The calculator uses the Social Security benefit formula:

\[ \text{Benefit} = \text{PIA} \times \text{age\_adjustment} \times \text{COLA\_adjustments} \]

Where:

$ \text{PIA} $ — Primary Insurance Amount ($/month)
$ \text{age\_adjustment} $ — Reduction for early claiming or increase for delayed claiming
$ \text{COLA\_adjustments} $ — Cumulative Cost of Living Adjustments

Explanation:

If claimed before FRA: Benefit is reduced by 5/9 of 1% per month for first 36 months, then 5/12 of 1% for additional months
If claimed after FRA: Benefit increases by 2/3 of 1% per month up to age 70
COLA adjustments are applied annually after claiming

3. Importance of Benefit Calculation
