Social Security COLA History: Every Raise Since 1975
Each year, more than 70 million Americans see their Social Security checks adjusted for inflation through the cost-of-living adjustment, or COLA. The size of that raise swings with the inflation rate — from double digits in the early 1980s to nothing at all in a few low-inflation years. This guide shows every annual COLA since automatic adjustments began in 1975, the record highs, the zero years, and exactly how the figure is calculated.
What is the Social Security COLA?
The cost-of-living adjustment is the automatic annual increase in Social Security and Supplemental Security Income benefits, designed to keep their purchasing power from being eroded by inflation. Before 1975, raises required an act of Congress; since then they've been automatic and tied directly to a measure of consumer prices. The chart above shows the size of the raise for each year — tall bars are high-inflation years, and the rare zero bars are years prices didn't rise enough to trigger an increase.
The biggest COLA increases
The largest adjustments came during the high-inflation early 1980s, topping out at 14.3% in 1980. More recently, the post-pandemic inflation surge produced an 8.7% raise for 2023 — the biggest in four decades. Because the COLA simply mirrors inflation, a large raise is a double-edged sword: bigger checks, but only because the cost of everything beneficiaries buy went up just as much.
The years with no COLA at all
In a handful of years — 2010, 2011, and 2016 — there was no COLA, because the measured inflation rate was flat or negative. By law the adjustment can never be negative, so benefits don't fall in deflationary years; they simply stay the same. Those zero years were a source of frustration for many retirees, even though they reflected unusually low overall inflation.
How the COLA is calculated
The COLA is based on the CPI-W — the Consumer Price Index for Urban Wage Earners and Clerical Workers. The Social Security Administration compares average prices in the third quarter (July–September) of the current year with the same quarter of the previous year; the percentage increase becomes the next year's COLA, announced each October and effective in January. Critics argue the CPI-W understates seniors' real costs, since retirees spend more on health care than the average worker the index is built around.
Frequently asked questions
What is the Social Security COLA?
It's the automatic annual cost-of-living adjustment that raises Social Security benefits to keep pace with inflation, in place since 1975.
What was the biggest Social Security COLA ever?
14.3% in 1980, during the high-inflation era. The largest recent raise was 8.7% for 2023, the biggest in four decades.
Has there ever been no COLA?
Yes — in 2010, 2011, and 2016 there was no adjustment because inflation was flat or negative. By law the COLA can't be negative, so benefits never fall.
How is the COLA calculated?
It's based on the CPI-W, comparing third-quarter prices year over year. The increase is announced in October and takes effect the following January.
Does the COLA keep up with seniors' costs?
Critics say no, because the CPI-W is built around working-age spending and may understate retirees' higher health-care costs.
