The inflation print has a second life as federal spending. The Social Security Administration announced on Wednesday that benefits will rise 3.6 percent in 2027, the annual cost of living adjustment calculated from the CPI for Urban Wage Earners and Clerical Workers over the third quarter. The increase is worth about 75 dollars a month on average, taking the average retired worker’s benefit from 2,087.52 dollars to 2,162.67 dollars from January 1, and applies to about 76 million Americans across Social Security and Supplemental Security Income. About 7.3 million SSI recipients receive the increased payments starting December 31, because January 1 is a federal holiday.
The adjustment is up from 2.8 percent for 2026 and is the largest since the 8.7 percent increase that took effect in 2023. The Senior Citizens League noted it is tied for 18th of the 52 adjustments since COLAs were tied to the CPI in 1975, and that its own model had projected 2.8 percent in January before fuel prices spiked after the start of the Iran war. The CPI-W rose 3.4 percent year on year in July, 3.5 percent in August and 3.9 percent in September, and the average of those readings sets the 3.6 percent figure by formula, with no congressional vote involved.
The revenue side moves with it. The maximum amount of earnings subject to Social Security tax rises to 192,300 dollars in 2027, from 184,500 dollars in 2026, and the earnings limit for workers younger than full retirement age rises to 25,560 dollars. Commissioner Frank Bisignano said the adjustment would give recipients greater financial stability, while beneficiary groups were quick to note that the formula index may lag the costs seniors actually face, particularly healthcare: in The Senior Citizens League’s 2026 survey, 89 percent of respondents said the previous COLA was too low.
For the rates calendar, the COLA is a reminder that September’s CPI does not fade after one trading session. It is now embedded in indexed federal outlays for 2027, in the payroll tax base, and, through the same index family, in inflation linked securities accruals, which is why a hot September print keeps echoing through fiscal projections long after the October FOMC has met.
