Social Security's 2027 COLA Is 3.6% — the Biggest Raise in Four Years, With Two Catches

Social Security benefits will rise 3.6% in January 2027 — the largest increase since the inflation-driven 8.7% jump of 2023 — the Social Security Administration announced Wednesday, October 14. For the roughly 72 million Americans who receive Social Security, that works out to about $75 more per month, lifting the average retired worker's check from approximately $2,095 to $2,170.

The adjustment, known as a COLA, is calculated each year from the Consumer Price Index for Urban Wage Earners and Clerical Workers — the CPI-W — comparing the average of July, August, and September against the same three months the prior year. The CPI-W averaged 328.746 in the third quarter of 2026, up 3.6% from 317.265 a year earlier, according to the SSA. Separately, the broader Consumer Price Index rose 3.7% in September compared with a year ago, driven in large part by a surge in gasoline costs, the Bureau of Labor Statistics announced the same day.

The 3.6% figure landed exactly in line with what Social Security experts had projected — the Senior Citizens League had estimated 3.6% in late summer, while AARP had forecast 3.5%, according to boldin.com. It also beats the 20-year average COLA of roughly 2.6%, though it falls well short of the five-year average, which was pulled upward by the 2022–2023 inflation spikes.

The roughly 7.3 million lower-income Americans who receive Supplemental Security Income (SSI) will see the same 3.6% increase, but their payments arrive earlier — in the check dated December 31, 2026 — because January 1 is a federal holiday, according to the SSA.

But two structural problems temper the good news for retirees.

The first is Medicare. Part B premiums — which cover doctor visits and outpatient services and are deducted directly from Social Security checks — are projected to rise to $209.50 a month in 2027, up $6.60 from this year's $202.90, according to Medicare's most recent trustees report. The Centers for Medicare and Medicaid Services will set the final number in November. At the projected level, that premium increase would consume roughly 9% of the average $75 monthly raise, according to boldin.com. Higher-income beneficiaries subject to Income-Related Monthly Adjustment Amount surcharges, known as IRMAAs, would lose even more of their COLA to premiums.

The second problem is deeper and longer-running: the inflation index used to calculate the COLA was not designed with retirees in mind. The CPI-W tracks spending by working-age urban households. Older Americans spend a disproportionately large share of their income on healthcare and housing — categories that have outpaced general inflation. Healthcare costs are projected to climb 5.8% a year long-term, according to HealthView Services, as cited by boldin.com, while Medicare Part B premiums alone rose 9.7% for 2026.

The cumulative effect is stark. Social Security benefits have lost 13.7% of their buying power over the past decade, according to an analysis by The Senior Citizens League cited by CNN — meaning a dollar of benefits in 2016 is worth only 86 cents today. Restoring that lost purchasing power for the average beneficiary would require a jump of nearly $296 a month, or about $3,550 a year, the analysis found.

An alternative index — the Consumer Price Index for the Elderly, or CPI-E — has tracked spending by people 62 and older since the Older Americans Act of 1987 required research into it, but Congress has never adopted it as the COLA benchmark. Some experts note the CPI-E does not necessarily grow much faster than the current measure, according to CNBC. Another proposed alternative, the chained CPI, would actually lower benefits over time, according to an AARP analysis cited by CNBC.

Looming behind both issues is Social Security's solvency. The program's trust fund is projected to be depleted in six years — around 2032 — at which point benefits would be payable at only about 78% of scheduled amounts without congressional action, according to CNN. The Committee for a Responsible Federal Budget, a watchdog group, noted that a higher COLA accelerates the drawdown of reserves and called on lawmakers to consider reforming future adjustments to help restore solvency.

The stakes are high for a population with limited financial cushion. About 40% of Social Security beneficiaries ages 65 and over rely on the program for at least half of their income, according to AARP. One in five older Americans has no retirement savings at all, AARP CEO Myechia Minter-Jordan noted.

A recent AARP survey found 76% of respondents said even a 3.5% COLA would not be enough to cover their rising costs, according to CNBC.

The 2027 COLA also triggers several other changes. The maximum amount of earnings subject to the Social Security payroll tax rises from $184,500 to $192,300, meaning workers earning above that threshold will pay the 6.2% tax on up to $7,800 more in wages — roughly $484 more annually, according to the SSA and boldin.com. SSI payment amounts also increase by 3.6%.

Beneficiaries can check their updated payment amounts through their online My Social Security accounts starting in late November; those without online accounts who want paperless notices must create an account and opt in by November 18, according to the SSA. Mailed COLA statements will go out in December. The final 2027 Medicare Part B premium — the number that will determine exactly how much of the raise lands in beneficiaries' bank accounts — is expected from CMS in November.

Why it matters — For the 72 million Americans on Social Security — many of whom depend on it for most of their income — the 3.6% COLA is the biggest raise in four years, but Medicare premium offsets and a structural mismatch between the inflation formula and retirees' actual spending mean the net gain is smaller than the headline, and a looming 2032 trust fund deadline puts the entire benefit structure at risk without congressional action.

Sources differ on Whether the CPI-E would produce meaningfully higher COLAs than the current CPI-W: CPI-E would better reflect retirees' costs, especially healthcare, and should replace CPI-W (cnn.com) vs CPI-E does not necessarily grow much faster than the current CPI-W measure (cnbc.com)
