How the 2018 Social Security Benefits Calculator Works

Key Components
- Average Indexed Monthly Earnings (AIME): Your average monthly earnings from your 35 highest-earning years, adjusted for inflation.
- Benefit Formula: Your monthly benefit is 90% of your AIME.
- Earnings Record: Your earnings history is used to determine your AIME.
Formula
Monthly Benefit = 0.9 × AIME
AIME = (Sum of indexed earnings for 35 highest-earning years) ÷ 420

- AIME = Average Indexed Monthly Earnings
- 420 = Number of months in 35 years
- 0.9 = Benefit multiplier (90% of AIME)
Worked Examples
Example 1: Single Filer
If you earned $500,000 from your 35 highest-earning years:
- AIME = $500,000 ÷ 420 = $1,190.48
- Monthly Benefit = 0.9 × $1,190.48 = $1,071.43
Example 2: Married Filer
If you and your spouse earned a combined $800,000 from your 35 highest-earning years:
- AIME = $800,000 ÷ 420 = $1,904.76
- Monthly Benefit = 0.9 × $1,904.76 = $1,714.28
