Social Security COLA Forecast: 3.8% in 2027
Social Security recipients are on track to receive a significantly larger cost-of-living adjustment in 2027, with new forecasts projecting a 3.8% increase that would push the average monthly benefit above $2,000 for the first time. The projected adjustment, one percentage point higher than the 2.8% COLA applied in 2026, comes as inflation remains stubbornly above the Federal Reserve’s target.
According to Fox Business, The Senior Citizens League (TSCL) projects the 2027 COLA at 3.8%, unchanged from last month’s estimate and down slightly from the 3.9% projection made in April. If that adjustment took effect today, average monthly benefits would rise by $73.62 — from $1,937.53 to $2,011.15.
How the COLA Is Calculated
By law, the annual Social Security COLA is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). The formula compares average CPI-W data from the third quarter (July through September) of the current year to the same period in the prior year. The official 2027 COLA will be announced in mid-October 2026 and take effect in January 2027.
June 2026 CPI data, released Tuesday, showed prices rising 3.5% year-over-year — well above the Fed’s 2% target. The CPI-W, the specific inflation gauge used for COLA calculations, also registered 3.5% annually. As CNBC reports, independent analyst Mary Johnson estimates a slightly lower 3.7% COLA for 2027, down sharply from her 4.7% projection last month.
“This is a significant drop in inflation, and one that we’ve rarely seen in the June CPI data over the past five years,” Johnson said.
The Impact on Seniors
TSCL Executive Director Shannon Benton emphasized the financial strain facing older Americans. “We’re seeing inflation on the rise when more than half of seniors already can’t afford basic living standards,” she told Fox Business. “We’re talking about food, a roof over their head, and transportation. Many seniors already have to skip doctor’s appointments due to costs, which costs all of us more in the long run when we swap preventative care for emergency care.”
A January 2026 survey by the Employee Benefit Research Institute and Greenwald Research found retiree confidence fell 5 percentage points to 73%, with top worries including inflation, debt, healthcare costs, and potential changes to the retirement system. Two in five retirees said healthcare costs were higher than expected.
The Fiscal Trade-Off
A larger COLA, while welcome news for beneficiaries, would also accelerate Social Security’s already precarious financial trajectory. The nonpartisan Committee for a Responsible Federal Budget (CRFB) estimates a 3.8% COLA would worsen the program’s fiscal shortfall by roughly $300 billion over the next decade and push trust fund insolvency three months earlier, according to CRFB analysis.
The 2026 Social Security Trustees Report projects the program’s key trust fund will be depleted in the fourth quarter of 2032, at which point automatic benefit cuts of approximately 22–25% would be triggered unless Congress acts.
Legislative Landscape
On July 14, the Social Security 2100 Act was reintroduced in Congress. The bill would raise benefits by 2%, set a minimum benefit at 125% of the federal poverty line, change the COLA calculation to the CPI for the Elderly (CPI-E), and extend trust fund solvency by 32 years through payroll tax increases on income over $400,000. However, as TSCL noted in its press release, GovTrack gives the bill a 0% chance of passing in the current Congress.
“Although the Social Security 2100 Act is unlikely to pass in the current Congress, it should,” Benton said. “The bill is the gold standard for Social Security reform and accomplishes the majority of changes older Americans want to see for the program.”
Medicare Offsets
Any COLA increase will be partially offset by rising Medicare costs. According to the annual Medicare trustees report, standard Part B premiums are projected at $209.50 per month in 2027, up from $202.90 in 2026 — an increase of 3.3%. Johnson noted that this increase is relatively modest compared to the historical average.
What to Watch
The final 2027 COLA will depend on CPI-W data for July, August, and September. The official announcement is expected in mid-October 2026. With inflation trending lower but still above target, the actual figure could land anywhere in the 3.7–3.8% range. Over 75 million Social Security and Supplemental Security Income beneficiaries will be watching closely.
The 10-year average COLA stands at 3.1%, according to the Social Security Administration. Even at the lower end of projections, the 2027 adjustment would exceed that average — a modest reprieve for seniors navigating a persistently expensive economy.
