Social Security COLA 2027 is set at 3.6%, the Social Security Administration announced on 14 October 2026. The adjustment reaches about 76 million people in the United States and lifts the average retired worker’s monthly payment by roughly $75 from January 2027. September inflation data published hours earlier completed the calculation.

What the 3.6% Is Worth in Dollars

The Social Security Administration estimates the average monthly benefit for a retired worker will rise to about $2,170 in January 2027. That is an increase of roughly $75 a month, or about $900 over the year.

Those figures are averages across tens of millions of recipients, not the amount any individual will receive. A person’s own increase is 3.6% of their own current benefit, so a $1,200 payment rises by about $43 and a $3,000 payment by about $108, before any deductions.

The Senior Citizens League, an advocacy group for older Americans in the United States, put the arithmetic slightly differently in its statement on the announcement, calculating that the average retired worker’s cheque moves “from $2,087.52 to $2,162.67, effective January 1st”. The small gap between that and the agency’s $2,170 reflects a different starting average, not a different adjustment.

For context on where the figure sits historically, recent adjustments have been 8.7% for 2023, 3.2% for 2024, 2.5% for 2025 and 2.8% for 2026. At 3.6%, the 2027 adjustment is the largest since 2023.

How the 3.6% Was Calculated

The adjustment is not set by judgement or negotiation. United States law ties it to a single index: the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W, which the Bureau of Labor Statistics publishes monthly.

The formula compares the average CPI-W reading for July, August and September of the current year against the same three months of the last year in which an adjustment took effect, then rounds the percentage increase to the nearest tenth. The reason the announcement waits until mid-October is simply that the September reading is the last input.

  • July 2026: CPI-W stood at 327.104.
  • August 2026: CPI-W stood at 328.481.
  • September 2026: CPI-W stood at 330.654.
  • Third-quarter 2026 average: 328.746.
  • Third-quarter 2025 average: 317.265.

The rise from 317.265 to 328.746 works out to about 3.62%, which rounds to 3.6%. The September reading that completed the calculation came in the Bureau of Labor Statistics release published at 8:30 a.m. Eastern Time on 14 October 2026, which put CPI-W up 3.9% over twelve months at an index level of 330.654.

That same release put the better-known headline measure, CPI-U, up 3.7% over twelve months, and the core measure excluding food and energy up 2.6%. Readers comparing numbers across coverage should note that the 3.6% adjustment, the 3.9% CPI-W annual rate and the 3.7% headline inflation rate are three different calculations from the same data.

Why the Net Increase Is Not Yet Knowable

As of 15 October 2026, nobody can say what the 3.6% adjustment will actually add to a retiree’s bank balance, because the largest routine deduction from a Social Security payment has not been set.

Most people enrolled in Medicare Part B, the United States programme that covers doctor visits and outpatient care, have the premium taken directly out of their monthly Social Security payment. The Centers for Medicare and Medicaid Services, the federal agency that runs Medicare, had not announced the 2027 Part B premium at the time of the cost-of-living announcement and normally publishes it later in the autumn.

The standard Part B premium is $202.90 a month in 2026. The Medicare trustees’ most recent projection points to $209.50 a month for 2027, an increase of $6.60. That projection is not the official rate, and the figure CMS eventually sets has in past years landed above trustee projections.

If the premium does rise by $6.60, it would absorb roughly $7 of an average $75 monthly increase. Higher-income beneficiaries pay income-related surcharges on top of the standard premium, so their deduction is larger. Our earlier report on Medicare Advantage premiums for 2027 covers the separate decisions facing people in private Medicare plans.

When the Higher Payments Arrive

The two programmes the agency runs do not change on the same date, and the difference catches people out every year.

  1. Supplemental Security Income: About 7.3 million recipients see the higher amount from 31 December 2026, because the January payment is issued at the end of December.
  2. Social Security retirement, survivor and disability benefits: The adjustment applies to benefits payable for January 2027, which arrive on each recipient’s normal January payment date.

Beneficiary counts also differ between announcements, which explains an apparent contradiction in coverage. Commissioner Frank Bisignano described the adjustment as reaching 76 million Americans, a figure that includes Supplemental Security Income recipients. Around 72 million Social Security recipients specifically will see the increase in January, according to agency figures cited by CNBC. Those 72 million received an average benefit of nearly $1,942 in August 2026, a figure that spans all benefit types rather than retired workers alone.

The agency notifies recipients of their own new amount by post in December and through online accounts; the official channel for an individual figure is the agency’s own notice rather than any average.

The Other 2027 Thresholds That Changed

The same annual announcement resets several dollar limits that have nothing to do with the size of a benefit cheque. These matter to people still working, whether or not they claim benefits.

Threshold20262027
Maximum earnings subject to Social Security tax$184,500$192,300
Earnings test limit, below full retirement age all year$24,480$25,560
Earnings test limit, in the year full retirement age is reached$65,160$67,920
Earnings needed for one work credit$1,890$1,970

The taxable maximum, also called the wage base, is the point at which Social Security payroll tax stops applying to a year’s earnings. It rises by $7,800 for 2027, which means higher-paid employees and their employers each pay tax on a larger slice of salary.

The earnings test applies to people who claim benefits before full retirement age and keep working. Below that age for the whole year, $1 of benefit is withheld for every $2 earned above $25,560. In the year someone reaches full retirement age, $1 is withheld for every $3 earned above $67,920, and the test stops applying from the month that age is reached. Withheld amounts are not forfeited permanently; the benefit is recalculated upward once full retirement age arrives. Full retirement age is 67 for anyone born in 1960 or later.

The earnings test and work credit figures above are drawn from reporting by Kiplinger and The Motley Fool on the agency’s annual fact sheet, which were consistent with each other; the agency’s own fact sheet is the authoritative record.

What Advocacy Groups Say the Figure Misses

The announcement drew immediate criticism from groups representing older Americans, who argue the index itself is the problem rather than this year’s reading.

The Senior Citizens League said the 2027 adjustment is too low and noted that the agency “must calculate COLAs with this method by law”. Its director said that “Congress cannot control every price increase, but it can act to ensure that the COLA formula does not leave people behind.”

The group and others have pressed for the adjustment to be based on CPI-E, an experimental index the Bureau of Labor Statistics maintains that weights spending patterns of people aged 62 and over more heavily toward medical and housing costs. Switching indexes would require an act of Congress, and no such change has been enacted.

Shannon Benton of the Senior Citizens League told CBS News that “while a 3.6% COLA is certainly welcome, it wouldn’t necessarily restore the purchasing power seniors have already lost.” Nancy Altman of Social Security Works told the same outlet that “people are getting crushed by prices”. A separate criticism concerns timing: because the adjustment is calculated from July-to-September data and applied from January, it lags the inflation it is meant to offset by several months.

These are the positions of advocacy organisations, not findings by the agency. The wider inflation picture behind them is set out in our report on Federal Reserve staff projections for the return to 2% inflation.

Frequently Asked Questions

What Is the Social Security COLA for 2027?

The Social Security COLA for 2027 is 3.6%, announced by the Social Security Administration on 14 October 2026 in the United States. It is the largest adjustment since 2023, when benefits rose 8.7%.

How Much More Will the Average Retiree Receive?

The agency estimates the average retired worker’s monthly payment rises by about $75, to roughly $2,170 from January 2027. That is an average across millions of recipients; an individual’s increase is 3.6% of their own current benefit.

When Does the 2027 Increase Start?

Supplemental Security Income recipients see the higher amount from 31 December 2026. Social Security retirement, survivor and disability benefits reflect it in payments for January 2027.

Will the Medicare Part B Premium Cancel Out the Increase?

That cannot be answered yet. The Centers for Medicare and Medicaid Services had not set the 2027 Part B premium as of 15 October 2026. The standard premium is $202.90 a month in 2026 and the Medicare trustees have projected $209.50 for 2027, which is a projection rather than the official rate.

Why Is the COLA 3.6% When Inflation Was Reported at 3.7%?

They measure different things. The 3.7% figure is the twelve-month change in CPI-U for September 2026. The adjustment uses CPI-W averaged over July to September and compares it with the same quarter a year earlier, which produced about 3.62% and rounded to 3.6%.

How Much Earnings Are Subject to Social Security Tax in 2027?

The maximum earnings subject to Social Security payroll tax rises to $192,300 in 2027 from $184,500 in 2026, an increase of $7,800. Earnings above that level in a calendar year are not subject to the tax.
