📊 How Social Security Benefits Are Calculated
Social Security uses your highest 35 years of earnings to compute your Average Indexed Monthly Earnings (AIME). The Primary Insurance Amount (PIA) is then calculated using a progressive formula:
| AIME Range (2026) | Replacement Rate |
|---|---|
| First $1,174 | 90% |
| $1,174 – $7,078 | 32% |
| Over $7,078 | 15% |
This progressive formula means lower earners replace a larger percentage of their pre-retirement income. The maximum monthly benefit at Full Retirement Age in 2026 is approximately $4,018.
