Social Security Commissioner Frank Bisignano appeared on CNBC's Squawk Box this week and called the forthcoming benefit adjustment "a good day" for seniors, adding that the program would remain solvent "for another 90 years." The official 2027 cost-of-living adjustment posts tomorrow, October 14, 2026, when the Bureau of Labor Statistics releases September inflation data at 8:30 a.m. Eastern—and while the headline number will be the largest increase in three years, the net change hitting most retirees' bank accounts will be smaller than the percentage suggests once Medicare deductions are factored in.
The COLA is set by a fixed statutory formula: the average of July, August, and September CPI-W figures compared to the same three months in the prior year. The Social Security Administration has no discretion over the number—it comes directly from BLS data. Based on figures already published for July and August 2026, independent analysts project the 2027 adjustment will land between 3.4% and 3.6%. The Senior Citizens League forecasts 3.5%, AARP forecasts 3.6%, and the Committee for a Responsible Federal Budget estimates 3.4%. For the average retiree receiving roughly $2,079 per month in 2026—per the SSA's fact sheet—a 3.5% increase would add approximately $73 to monthly payments before any deductions. The adjustment applies to more than 70 million Social Security and SSI recipients. The original October 5 COLA forecast article covered the calculation methodology and the prior year's 2.8% baseline.
Retirees, disabled beneficiaries, and fixed-income household budgeters face meaningful payment increases for 2027 following an uptick in inflation data ahead of Wednesday's official announcement. Beneficiaries planning annual household budgets should anticipate a cost-of-living adjustment between 3.4% and 3.6%, translating to approximately $73 extra per month at the projected midpoint before any deductions. Recipients must also account for rising Medicare Part B monthly premiums, which will offset a portion of next year's gross benefit increase.
The Medicare Deduction Most COLA Headlines Skip
Commissioner Bisignano's 90-year solvency claim is a political message, not a statutory fix. The Social Security Trust Fund's projected depletion date remains in the mid-2030s under current law, unchanged without congressional action to adjust payroll tax rates or benefit structures. His statement reflects the administration's confidence that legislative reform will come; it doesn't alter the underlying funding math.
The more immediate practical issue for beneficiaries calculating their January check is Medicare Part B. The standard monthly Part B premium—which covers outpatient care for Medicare-enrolled Social Security recipients—is expected to increase in 2027. When Part B premiums rise, the amount is automatically deducted from Social Security payments before the beneficiary sees a dollar. The 2026 Social Security Trustees Report projects the standard monthly Part B premium will rise approximately $6.60 per month, from $202.90 to $209.50, though the final 2027 rate has not yet been officially announced by the Centers for Medicare and Medicaid Services.
For someone receiving $2,079 per month, a 3.5% COLA adds roughly $73 gross. If Part B premiums rise by the projected $6.60, the net increase in spendable income would be approximately $66 per month. That is the number that matters for someone budgeting groceries and utilities, not the percentage figure alone.
This year's projected adjustment would be the largest in three years, reflecting a moderate uptick in inflation following a period of cooling. The 2023 COLA was 8.7% at the peak of inflation; the 2026 adjustment came in at 2.8%. The 2025 rate was 2.5%. The current projected 3.5%–3.6% for 2027 would surpass all three recent years.
Congress has debated switching the COLA benchmark from CPI-W to CPI-E (the Consumer Price Index for the Elderly), which weights healthcare spending more heavily. No legislation has passed to make that switch.
The official 2027 COLA percentage posts tomorrow morning, October 14, 2026, immediately after the 8:30 a.m. BLS release. The SSA will confirm the exact figure on its website the same day. Beneficiaries will receive an individualized notice by mail before January. Check back here Wednesday morning for updated figures once the official announcement is confirmed.
