Earnings record rule
The Social Security 35-Year Earnings Rule
Social Security generally bases a retired-worker benefit on the highest 35 years of wage-indexed earnings. If fewer than 35 years are available, zero years enter the average. A new year can raise the estimate when it replaces a zero or a lower indexed year.

Why a zero year matters
The highest-35 total is divided across 420 months to calculate average indexed monthly earnings. If only 30 earning years are available, five zero years are part of that calculation. The effect varies with the rest of the record and the PIA formula, so it is not accurate to promise a fixed dollar increase from one additional work year.
Claiming Planner shows how many zero years appear in the modeled highest 35 and identifies which entered years were selected.
Why the highest dollar amount is not always obvious
Older earnings are generally wage-indexed before the highest years are selected. The taxable maximum can also cap covered earnings for a year. That means an older nominal amount may contribute more after indexing than a newer number that looks larger on the original record.
How another work year can help
A later covered-earnings year can replace a zero or a lower selected year. If it does not enter the highest 35, it may not change AIME. Model the proposed work year and inspect the detailed selected-year table rather than assuming every additional year creates the same increase.
