1980 — 14.3%
The largest COLA since automatic increases began in 1975, and not matched since. It came in a period of high inflation in the late 1970s and was followed a year later by the second-largest.[2]
Since automatic COLAs began in 1975, benefits have never risen more than the 14.3% of 1980; the 8.7% increase paid from January 2023 is the only one since 1982 to reach the top five.

How to read this: every row is one year’s automatic COLA as listed in the Social Security Administration’s historical series, which labels each increase by the year it took effect and starts in 1975. From the 1983 adjustment on, that is December of the labelled year, paid in January of the next, so the 8.7% increase labelled 2022 reached checks in January 2023 and is usually called the 2023 COLA. Ties share a rank (1977 and 2021 are both 5.9%), so the next rank is skipped. The 2027 COLA, announced on 14 October 2026, is 3.6%: that would rank 18th, tied with the 3.6% of 2011, so it is outside this table. “CPI-W comparison” gives the periods compared for each year as the SSA describes its method: first-quarter averages for the mid-year COLAs of 1975–1982 (1975 compared the second quarter of 1974 with the first quarter of 1975), third-quarter averages from the 1983 adjustment on; the date a mid-year increase began paying is simplified to “mid-year”. A COLA is a percentage of each person’s existing benefit, so the same percentage means a different dollar amount for each beneficiary, and a single year’s figure hides the cumulative effect on purchasing power: a string of modest COLAs can add up to more than one large one, and a COLA only reflects the CPI-W change since the previous measurement.[1]
The largest COLA since automatic increases began in 1975, and not matched since. It came in a period of high inflation in the late 1970s and was followed a year later by the second-largest.[2]
The second-highest COLA came just after the record of 1980. Inflation through the early 1980s was influenced by energy-price shocks and tight monetary policy, and it took time to cool.[2]
The third-highest COLA, and the only one of the 1970s to come close to double digits. It was followed by the two largest increases on record, in 1980 and 1981.[2]
The largest COLA in more than four decades, announced on 13 October 2022 after consumer prices rose sharply following the pandemic. The SSA said it covered about 70 million people receiving Social Security or SSI, with the increase beginning in January 2023 for more than 65 million Social Security beneficiaries. It is the only COLA since 1982 to rank in the top eight.[3]
The first automatic COLA. Before 1975, benefit increases generally required an act of Congress; from then on they followed the rise in consumer prices under the formula in law. The first increase compared the second quarter of 1974 with the first quarter of 1975.[2]
The last of the mid-year COLAs. From the 1983 adjustment the measuring period moved to the third quarter and increases took effect in December, so the 3.5% COLA of 1983 was measured and paid on a different schedule from earlier ones.[2]
Together with 1976’s 6.4%, one of two COLAs of about 6.5% in the 1970s; no COLA since 1982 has reached that level.[2]
The second automatic COLA, just behind 1978’s. It was the first of a run of eight straight COLAs from 1975 to 1982, none below 5.9%.[2]
Tied with the COLA of 2021 at 5.9%. Between 1975 and 1982, every annual COLA was at least 5.9%, a run that has no equivalent in the decades since.[2]
Announced on 13 October 2021 as the largest increase in about 40 years at that point; the SSA tied it to the CPI-W as measured by the Bureau of Labor Statistics. The estimated average retired-worker benefit was projected to rise from $1,565 to $1,657 a month. The 2022 COLA of 8.7% followed a year later.[3]
