SSA’s own table lists this adjustment under 1992, the year it was determined. The public name it by the year it reaches a check, which is one later. This site uses the name people search for. Why the two labels disagree.

The CPI-W values behind the 3.0%

Every adjustment is an average of three monthly index readings against an average of three others. These are the six values, as the Bureau of Labor Statistics published them for series CWUR0000SA0 — all items, U.S. city average, not seasonally adjusted.

Comparison quarter average138.8

The quarterly averages are rounded to the nearest tenth — the precision the determination-1992 notice specifies — and the percentage increase between them is then rounded to the nearest tenth of a percentage point. That gives 3.0%.

Reproduced from the raw index

Recomputing this adjustment from the committed CPI-W series returns 3.0%, matching SSA’s published figure. That check runs on all 51 determinations as a blocking build gate, so no page here can ship a figure the arithmetic does not support.

What 3.0% did to a benefit

Monthly benefit amounts are floored to the whole dollar after the adjustment is applied, which is why these figures are not simply the percentage multiplied out.
