Social Security Projects 3.5 Percent Benefit Increase for 2027

More than 70 million Americans who receive Social Security benefits could see their monthly payments increase by 3.5% to 3.6% in 2027, based on current projections. The Social Security Administration is scheduled to announce the official cost-of-living adjustment (COLA) on October 14, after the Bureau of Labor Statistics releases September inflation data needed to complete the calculation.

The projected increase would exceed the 2.8% adjustment beneficiaries received in 2026 and mark the largest annual increase since the 8.7% adjustment that took effect in 2023. The Senior Citizens League forecasts a 3.5% increase, while AARP projects 3.6%, according to reports published by USA Today and Newsweek.

The adjustment is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). The Social Security Administration compares the average index for July, August and September with the average for the same months in the previous year to determine the percentage increase in benefits.

According to The Senior Citizens League, the CPI-W increased 3.4% year over year in July and 3.5% in August. September's inflation figure will determine the final adjustment, which could differ from current estimates.

The potential increase comes amid renewed inflationary pressure associated with higher energy costs, the ongoing conflict in the Middle East and earlier tariff increases that have raised the cost of imported goods. Newsweek reported that persistent price increases in services have also contributed to inflation during 2026.

For a retired worker receiving the average monthly benefit of $2,087.52 in August, a 3.5% adjustment would add approximately $73 per month, bringing the payment to about $2,161. A 3.6% increase would add roughly $75, raising the monthly benefit to approximately $2,163, according to Social Security Administration figures cited by Newsweek.

Disabled workers received an average of $1,635.90 per month in August. Under the current projections, their monthly payments could rise by approximately $57 to $59, reaching between $1,693 and $1,695.

For nondisabled widows and widowers, the average monthly benefit of $1,934.37 could increase by approximately $68 to $70. Supplemental Security Income recipients, whose average monthly payment was $738.73, could receive an additional $25 to $26 per month under the same projections.

Higher benefit payments would not necessarily translate into equivalent gains in purchasing power because Medicare premiums and household expenses could absorb part of the increase. USA Today reported that Medicare trustees projected a 3.25% increase in Medicare Part B premiums for 2027, equivalent to $6.60 more per month, bringing the premium to $209.50.

The final Medicare Part B premium figure is expected between late October and early November. The Senior Citizens League has also highlighted the long-term gap between benefit adjustments and health care costs, noting that Part B premiums have risen faster than COLA in seven of the past 10 years.

Energy expenses could further strain retirees' budgets. The National Energy Assistance Directors Association expects the cost of heating a home with heating oil this winter to be 50% higher than last winter, while continued fighting in the Middle East is expected to keep gasoline and diesel prices elevated.

Prescription drug coverage costs may also increase for some beneficiaries. Health policy researcher KFF reported that 28% of prescription drug plan enrollees who did not receive low-income subsidies, representing approximately 4 million people, paid no monthly premium in 2026. Some of those enrollees could face new monthly charges in 2027.

Mary Johnson, an independent Social Security and Medicare analyst, said the final adjustment could fall to 3.4% if September inflation comes in lower than expected. She estimated that a 0.1-percentage-point difference would amount to about $20 per month for someone receiving an average Social Security benefit of $2,000.

The Committee for a Responsible Federal Budget also projected a 3.4% adjustment, while AARP's 3.6% forecast represents the higher end of current estimates. Earlier projections were substantially lower: the expected 2027 increase stood at 1.2% based on January inflation data before energy prices rose.

The Social Security Administration will determine the final adjustment after the September CPI-W figures are available on October 14. The increase will apply to December 2026 benefits paid beginning in January 2027, while Supplemental Security Income recipients generally receive their adjusted January payments at the end of December because January 1 is a federal holiday.
