Key Points
Social Security's 2027 COLA could reach 3.8%, raising average monthly benefits by $77.
Tariffs and geopolitical inflation are driving the larger-than-normal raise.
The CPI-W index used to calculate COLA underweights healthcare costs that retirees actually face.
44% of retirees depend entirely on Social Security for income.
Social Security recipients could see a 3.8% cost-of-living adjustment in 2027, according to estimates from The Senior Citizens League. That would raise the average retiree’s monthly benefit by $77, from $2,026.41 to $2,103.41. The larger-than-normal raise reflects elevated inflation driven by tariffs and geopolitical tensions, but experts warn the boost may not fully offset the purchasing power retirees have lost since 2010.
Why the 2027 raise is bigger than usual
This year, Social Security recipients got a 2.8% raise. Next year’s adjustment is projected to be one percentage point higher, at 3.8%, according to The Senior Citizens League’s June analysis. The main driver is inflation. Tariffs imposed by the Trump administration in April 2025 raised consumer prices, and a new round of tariffs on more than 80 countries in July 2026 is expected to push prices higher still. Social Security calculates its annual raise using the Consumer Price Index for Urban Wage Earners and Clerical Workers, which tracks inflation across the economy.
The inflation metric doesn’t match retiree spending
Social Security uses the CPI-W to calculate the COLA, but that index is not designed for seniors. Healthcare costs make up 11.3% of what retirees actually spend, yet the CPI-W weights healthcare at only 6.9%. According to The Senior Citizens League, the average retiree has lost roughly 13.7% of buying power since 2010, even after annual raises. A better index, the CPI-E, exists but requires an act of Congress to adopt.
44% of retirees depend entirely on Social Security
The stakes are high. According to TSCL’s 2026 Senior Survey, 44% of retirees, or 24.8 million older Americans, depend on Social Security for all their income. That share jumped from 39% in 2025. Even with a 3.8% raise, many retirees will struggle. The larger COLA comes at a potentially steep cost to Social Security’s long-term solvency.
When the 2027 COLA will be announced
The Social Security Administration will announce the official 2027 COLA on October 14, 2026, after the Bureau of Labor Statistics releases September inflation data. The raise takes effect with payments beneficiaries receive in January 2027. AARP has forecast a 3.6% COLA based on July inflation data, while some analysts predict it could reach 4.7% or higher.
Final Thoughts
A 3.8% Social Security raise in 2027 would be the largest since the early 1990s, but it reflects elevated inflation rather than real gains in purchasing power. Retirees should plan for the January 2027 increase while recognizing that even higher COLAs may not keep pace with their actual costs.
