Social Security COLA History: Every Cost-of-Living Raise From 2000 to 2027
Short answer: Social Security has paid automatic cost-of-living adjustments (COLAs) since 1975 (SSA). The COLA was 2.8% in January 2026, and on October 14, 2026, SSA announced a 3.6% COLA for January 2027 (SSA). From January 2001 through January 2026, COLAs compounded to about 2.6% a year, with three years at zero (January 2010, 2011 and 2016).
How the COLA is set, and why the years get confusing
The COLA follows the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), which the Bureau of Labor Statistics (BLS) publishes. SSA compares the average CPI-W for July, August and September with the same three months a year earlier (SSA). If prices went up, benefits go up by that percentage. If prices did not go up, there is no COLA, and benefits do not go down.
SSA announces the number in October, after the September price data comes out. The raise shows up in the January check.
Here is the part that trips people up. SSA's own COLA table (SSA COLA series) lists each raise under the year it takes effect for December benefits. Those December benefits are paid in January. So the 2.8% that SSA's table shows for 2025 is the raise people received in January 2026, often called the 2026 COLA. This guide labels every raise by the January it was first paid, and shows SSA's table year next to it.

Margaret's $2,000 check from 2010
The workshop slide behind this guide made a point about a $2,000 check in 2010. Here is that idea with SSA's actual numbers. Margaret is a hypothetical retiree. Her benefit was $2,000 a month in January 2010. We apply each COLA from January 2011 through January 2026.
| Check paid in | COLA | Margaret's monthly benefit |
|---|---|---|
| January 2011 | 0.0% | $2,000 |
| January 2012 | 3.6% | $2,072 |
| January 2013 | 1.7% | $2,107 |
| January 2014 | 1.5% | $2,139 |
| January 2015 | 1.7% | $2,175 |
| January 2016 | 0.0% | $2,175 |
| January 2017 | 0.3% | $2,182 |
| January 2018 | 2.0% | $2,225 |
| January 2019 | 2.8% | $2,288 |
| January 2020 | 1.6% | $2,324 |
| January 2021 | 1.3% | $2,354 |
| January 2022 | 5.9% | $2,493 |
| January 2023 | 8.7% | $2,710 |
| January 2024 | 3.2% | $2,797 |
| January 2025 | 2.5% | $2,867 |
| January 2026 | 2.8% | $2,947 |
The arithmetic: $2,000 times 1.036, times 1.017, and so on through 1.028 equals about $2,947 by January 2026 (COLAs from SSA). That is about 47% more than in 2010. SSA rounds each benefit down to the dime, so a real check could be a few cents lower. With the 3.6% COLA for 2027, her check would be about $3,053 in January 2027.
The slide said $2,000 in 2010 grew to about $2,500 by 2025. The actual COLAs took it to about $2,867 by January 2025. The slide's larger point still deserves a look: the COLA tracks an average price index, and Margaret's own costs may rise faster. The next sections show where that can happen.
Every Social Security COLA, 2000 to 2027
All percentages are from SSA (SSA COLA history). The 2027 figure was announced October 14, 2026.
| Raise first paid in | COLA | Year in SSA's own table |
|---|---|---|
| January 2000 | 2.5% | 1999 |
| January 2001 | 3.5% | 2000 |
| January 2002 | 2.6% | 2001 |
| January 2003 | 1.4% | 2002 |
| January 2004 | 2.1% | 2003 |
| January 2005 | 2.7% | 2004 |
| January 2006 | 4.1% | 2005 |
| January 2007 | 3.3% | 2006 |
| January 2008 | 2.3% | 2007 |
| January 2009 | 5.8% | 2008 |
| January 2010 | 0.0% | 2009 |
| January 2011 | 0.0% | 2010 |
| January 2012 | 3.6% | 2011 |
| January 2013 | 1.7% | 2012 |
| January 2014 | 1.5% | 2013 |
| January 2015 | 1.7% | 2014 |
| January 2016 | 0.0% | 2015 |
| January 2017 | 0.3% | 2016 |
| January 2018 | 2.0% | 2017 |
| January 2019 | 2.8% | 2018 |
| January 2020 | 1.6% | 2019 |
| January 2021 | 1.3% | 2020 |
| January 2022 | 5.9% | 2021 |
| January 2023 | 8.7% | 2022 |
| January 2024 | 3.2% | 2023 |
| January 2025 | 2.5% | 2024 |
| January 2026 | 2.8% | 2025 |
| January 2027 | 3.6% | 2026 |
A few points stand out. The largest raise in this period was 8.7% in January 2023, after prices rose quickly in 2022. Since automatic COLAs began, the largest was 14.3%, paid in July 1980 (SSA). From 1975 to 1982, COLAs were paid in July. Since January 1984, they have been paid in January.
COLA vs inflation: CPI-W and CPI-E
On paper, the COLA keeps up with inflation, because it is inflation as measured by the CPI-W. The real questions are which prices are measured, and when.
Whose prices. The CPI-W tracks households where most income comes from wages. It leaves out households with no one working, such as retirees (BLS). BLS also publishes a research index for Americans 62 and older, called R-CPI-E, which weights spending the way older households spend (BLS).
From December 1982 to December 2025, R-CPI-E rose about 255%, while CPI-W rose about 224% (BLS data). That is about 3.0% a year compared with about 2.8% a year. Older households spend more on health care and housing. The medical care part of R-CPI-E rose about 513% over the same period.
BLS cautions that R-CPI-E is a research series with limits: a small sample, and stores and areas chosen for the whole population. So treat the gap as a rough guide, not a precise shortfall.
When. The COLA looks backward. Prices rose quickly through 2022, but the 8.7% raise did not arrive until January 2023. During a fast run-up, retirees pay the higher prices for months before the raise catches up.
How much of the COLA Medicare takes
For most retirees on Medicare, the Part B premium comes out of the Social Security check. The standard Part B premium was $45.50 a month in 2000 (SSA Statistical Supplement, Table 2.C1). In 2026 it is $202.90 (CMS). That is about 4.5 times as much.
Over the same years, COLAs from January 2001 through January 2026 raised benefits about 1.94 times. So the premium grew more than twice as fast as the check.
The 2026 example
The average retired worker's benefit rose from $2,015 to $2,071 in January 2026, a $56 raise (SSA). The standard Part B premium rose from $185.00 to $202.90, an increase of $17.90 (CMS). So $17.90 of the $56 raise, about 32%, went to the higher premium.
SSA notes a hold-harmless rule that, for many people, keeps the Part B increase from being larger than the dollar amount of their COLA (SSA). The 2027 Part B premium had not been announced as of October 14, 2026. CMS usually announces it in the fall. For more detail, see how Medicare takes back part of the COLA.
What to do with this history
- Check your new amount. Your COLA notice shows the new benefit and any Medicare deduction. SSA says notices for 2027 will be online in late November 2026 for people with a my Social Security account.
- Plan with a modest raise. Over 2001 to 2026, COLAs averaged about 2.6% a year. Some years were zero.
- Budget the net raise, not the gross one. Subtract any Part B increase once CMS announces the 2027 premium.
- Watch taxes. The income levels that make Social Security taxable ($25,000 single and $32,000 joint) are not indexed, so COLAs can slowly make more of a benefit taxable. See is Social Security taxable, and ask a tax professional to model your case.
- For other questions, call SSA at 1-800-772-1213.
Common mistakes
- Mixing up the year labels. A COLA announced in October 2026 is paid in January 2027.
- Treating forecasts as fact. Until SSA announces a COLA, any number is an estimate.
- Assuming the COLA is the whole raise. Medicare premiums, and sometimes taxes, take part of it.
- Comparing a COLA to one item, like eggs or rent. The index averages many prices. Your own mix may rise faster or slower.
These numbers change every year
The IRMAA brackets, the standard deduction and the senior deduction are all adjusted annually, and the 2027 figures are published late in 2026. The one exception is the Social Security taxation thresholds, which have not moved since 1983 and are not expected to.

Has Social Security ever had no COLA?
Yes. There was no COLA in January 2010, January 2011 or January 2016, because the CPI-W did not rise over the measuring period. Benefits did not go down.

Does the COLA keep up with inflation for retirees?
It matches the CPI-W, a measure of wage earners' prices. A BLS research index for people 62 and older rose somewhat faster from 1982 to 2025, mainly because of health care and housing costs.
When is the COLA announced?
SSA announces the COLA in October, after September CPI-W data is released. The raise is first paid in the January check.
