Social Security Administration 2027 COLA: Announcement Date, 2.7% Estimate, and Full Payment Timeline

The Social Security Administration will announce the 2027 cost-of-living adjustment (COLA) on Thursday, October 15, 2026, when the Bureau of Labor Statistics publishes September CPI-W data. Independent forecasts, including The Senior Citizens League's September 2026 estimate, point to a 2.7% increase, which would raise the average retired-worker benefit by roughly $54 per month starting in January 2027.

When will the 2027 Social Security COLA be announced?

The 2027 COLA will be announced on October 15, 2026, at 8:30 a.m. ET, when the BLS releases the September Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). By law, the SSA must announce the following year's COLA in October, immediately after the third-quarter CPI-W data is finalized, as required under the Social Security Act. The Hill and NewsNation both confirmed the mid-October timing in recent reporting, noting the announcement typically lands within days of the September inflation report.

What is the estimated 2027 COLA increase?

The 2027 COLA is currently estimated at 2.7%, according to The Senior Citizens League's September 2026 forecast, down from the 3.2% projection issued in mid-2026 as energy and shelter inflation cooled. If realized, a 2.7% COLA would be the smallest adjustment since the 2.5% bump in 2025, but still above the 2.0% average of the past decade. The Motley Fool and Kiplinger both flagged the 2.7% figure as the consensus range heading into the October 15 announcement.

How is the Social Security COLA calculated?

The COLA is calculated by comparing the average CPI-W for the third quarter (July, August, September) of the current year to the same quarter of the previous year. The percentage increase, rounded to the nearest tenth of a percent, becomes the COLA applied to all benefits the following January. If inflation is flat or negative, the COLA is set to zero, though benefits never decrease. According to the SSA's 2026 Trustees Report, the program's automatic adjustment mechanism has raised benefits by a cumulative 27.1% since 2021.

When do the 2027 COLA increases appear in payments?

The 2027 COLA takes effect with benefits payable for January 2027, which most recipients receive in their January payment. Because of the payment schedule, beneficiaries who receive checks on the second, third, or fourth Wednesday of the month will see the increase in their January 2027 deposit. Supplemental Security Income (SSI) recipients receive their first increased payment on December 31, 2026, since no January 1 payment is issued when the date falls on a holiday.

• SSI recipients: first raised payment December 31, 2026
• Retired workers with birthdays on the 1st through 10th: January 13, 2027
• Retired workers with birthdays on the 11th through 20th: January 20, 2027
• Retired workers with birthdays on the 21st through 31st: January 27, 2027

What does a 2.7% COLA mean in dollars for the average retiree?

A 2.7% COLA would add approximately $54 per month to the average retired-worker benefit, lifting it from about $2,031 in 2026 to roughly $2,085 in 2027, based on SSA's 2026 fact sheet. For a couple both receiving benefits, the combined increase would be about $108 per month, or roughly $1,296 per year. However, Medicare Part B premiums are deducted directly from Social Security checks, and the 2027 Part B premium is projected to rise about 5.2% to $206.50 per month, according to the 2026 Medicare Trustees Report, which would absorb a meaningful share of the COLA for many retirees.

"The 2027 COLA is shaping up to be a modest but meaningful raise, though Medicare premium hikes and the lagging CPI-W formula mean many seniors will still feel a squeeze," said Mary Johnson, an independent Social Security and Medicare policy analyst, in a September 2026 note.

Why is the 2027 COLA lower than the 2026 increase?

The 2027 COLA is lower than 2026's 2.8% because inflation cooled through the third quarter of 2026. Energy prices fell 4.1% year over year in August 2026, according to BLS data, while shelter inflation slowed to 3.6%, its lowest reading since early 2022. The Federal Reserve's decision to hold rates steady through the summer of 2026 also contributed to slower services inflation, reducing the CPI-W's third-quarter average.

How does the 2027 COLA compare to prior years?

The 2027 COLA at 2.7% would rank as the sixth-smallest adjustment since 2010, well below the 5.9% in 2022 and the 8.7% in 2023, but above the zero COLA years of 2010, 2011, and 2016. According to the SSA's 2026 Trustees Report, the 2027 COLA is projected to add approximately $28 billion in annual benefit outlays, contributing to the program's combined trust fund depletion date of 2034.

What should beneficiaries do before the October 15 announcement?

Beneficiaries should verify their my Social Security account information and check their Medicare Part B and Part D premium notices, which are typically released in November. The SSA will mail COLA notices in December 2026, and beneficiaries can view their personalized benefit amount online starting in early December. Financial planners recommend using the projected 2.7% figure for 2027 budgeting now, then adjusting once the official number is confirmed on October 15.
