The 2027 Social Security cost-of-living adjustment (COLA), the automatic yearly inflation increase to benefits, is 3.6%. It is the largest increase since the 8.7% COLA for 2023 and tops the increases for 2024 through 2026. Payments reach nearly 72 million beneficiaries in January 2027 and about 7.3 million SSI recipients on Dec. 31, 2026, covering 76 million Americans total, according to the SSA Office of Inspector General in its COLA announcement notice.

What the increase means in dollars
The 3.6% increase adds about $75 per month, or about $900 per year, to average benefits, according to analysis from the American Action Forum in its COLA estimate breakdown. A $2,000 monthly check rises by about $72 to about $2,072.
That math is proportional. Higher checks gain more dollars, while lower checks gain fewer. Use your current benefit as the base for planning.
How does 2027 compare to recent years?
The 2027 rate of 3.6% exceeds the 2.8% COLA for 2026, 2.5% for 2025 and 3.2% for 2024, according to Social Security Administration releases described in the agency's 2025 COLA release. It breaks a run of smaller post-inflation adjustments.
For retirees, the shift matters for budgets. A 3.6% raise restores more buying power than the last three years did.

That rank still sits well below past inflation peaks. CPA Practice Advisor's history puts the extremes at 14.3% in 1980, 11.2% in 1981 and 9.9% in 1979, with no COLA paid in 2010, 2011 or 2016 when prices did not rise, as detailed in its COLA history review. Zero-COLA years remain possible when inflation stalls.
How is the COLA calculated?
The Society of Actuaries explains that SSA sets the COLA from the year-over-year change in the third-quarter average of the Consumer Price Index for Urban Wage Earners, or CPI-W. The result rounds to the nearest 0.1%.
Timing follows a fixed rule. The increase applies to December benefits paid in January. SSI follows its own December payment date.
Why might your check rise less?
CPI-W tracks wage-earner spending, not retirees' heavier health and housing costs. Critics cited by Motley Fool say that mismatch can understate senior inflation.
Rising 2027 Medicare Part B premiums can also shrink the net gain. Beneficiaries need take no action because the increase is automatic, according to the SSA Office of Inspector General. Check the new amount online through my Social Security up to three weeks before mailed notices arrive.
