Key Points
Social Security COLA for 2027 projected at 3.5% to 3.6%, highest since 2023.
Average retiree's monthly benefit could rise by $67 to $75 starting January 2027.
Official announcement October 14 after September inflation data released.
Over 75 million people receive Social Security and depend on annual COLA adjustments.
Social Security recipients face a 3.5% to 3.6% cost-of-living adjustment in 2027, the largest increase in three years. The Senior Citizens League and AARP released competing projections on September 11 based on August inflation data. An average retiree’s monthly check could rise by $67 to $75 starting January 2027. The official figure arrives October 14 after September inflation data is released.
What the latest inflation data shows
The August Consumer Price Index for Urban Wage Earners and Clerical Workers rose 3.5% year-over-year, the Bureau of Labor Statistics reported Friday. This CPI-W figure, not the broader headline inflation rate, determines Social Security COLA adjustments. Gas prices spiked 3.9% in August amid the ongoing U.S.-Iran war, pushing overall inflation higher than expected.
Competing projections from advocacy groups
The Senior Citizens League now projects a 3.5% COLA, down 0.1 percentage point from its August estimate of 3.6%. AARP forecasts 3.6%, up from its prior 3.5% projection. Both groups base their estimates on two of the three monthly inflation readings used in the final calculation. Independent analyst Mary Johnson also projects 3.5%, though she noted volatile oil prices could shift the outcome.
What a 3.5% to 3.6% increase means for retirees
A 3.5% COLA would boost the average retiree’s monthly check by $67.90, from $1,940.08 to $2,007.98, according to TSCL. A 3.6% adjustment would raise the average benefit by $75 per month to roughly $2,146, per AARP. Over 75 million people receive Social Security or Supplemental Security Income. Recipients will receive personalized notices detailing their new benefit amounts in December.
When the official announcement arrives
The Social Security Administration will announce the official 2027 COLA on October 14, following the Bureau of Labor Statistics’ release of September inflation data. This will be TSCL’s final forecast before the official figure. The 2027 adjustment would mark the largest annual increase since 2023’s 8.7% jump, though critics say it may disappoint seniors because the CPI-W does not fully reflect older Americans’ actual spending patterns, particularly on healthcare.
Historical context and concerns
Social Security recipients received a 2.8% COLA for 2026, following 2.5% increases in 2025 and 3.2% in 2024. Over the past decade, COLA adjustments have ranged from 0% in 2016 to 8.7% in 2023, averaging about 3.1%. Shannon Benton, executive director of the Senior Citizens League, warned that seniors allocate their budgets differently than working-age people, so inflation hits them harder. Rising healthcare costs remain a particular burden despite COLA increases.
Final Thoughts
A 3.5% to 3.6% COLA would deliver the largest Social Security increase since 2023, boosting average monthly benefits by $67 to $75 starting January 2027. The official figure arrives October 14 after September inflation data is released. Advocates caution that even this increase may not fully offset the price pressures seniors face.
FAQs
The Social Security Administration will announce the official 2027 COLA on October 14, 2026, following the release of September inflation data from the Bureau of Labor Statistics.
If the COLA is 3.5%, average monthly benefits rise by $67.90. If it is 3.6%, the increase is about $75 per month, starting January 2027.
AARP projects 3.6% while the Senior Citizens League projects 3.5%. Both use the same two months of inflation data available so far, but may weight or interpret them slightly differently.
Advocates say no. The COLA uses the CPI-W, which does not fully reflect older Americans’ spending patterns, especially rising healthcare costs that hit retirees harder than working-age people.
A 3.5% to 3.6% increase would be the largest since 2023’s 8.7% jump. Recipients got 2.8% in 2026, 2.5% in 2025, and 3.2% in 2024.
