Monthly Benefit vs Primary Insurance Amount (PIA)

How Social Security Benefits Are Calculated

Your benefit depends on your Primary Insurance Amount (PIA) and the age you start collecting.

Claiming Early (before FRA)

  • Reduced by 5/9 of 1% per month for the first 36 months early
  • Reduced by 5/12 of 1% per month beyond 36 months
  • Delayed Retirement Credits (after FRA)

  • Increased by 8% per year (2/3 of 1% per month) up to age 70
  • Example Calculation

    PIA of $2,500, claiming at age 62 with FRA of 67.

    1. 01Months early = (67 − 62) × 12 = 60 months
    2. 02First 36 months: 36 × 5/900 = 20% reduction
    3. 03Remaining 24 months: 24 × 5/1200 = 10% reduction
    4. 04Total reduction = 30%
    5. 05Monthly benefit = $2,500 × (1 − 0.30) = $1,750
