With July and August CPI‑W data available, independent forecasts cluster in the mid‑3% range for the 2027 COLA. The final number depends on September's report and how energy and shelter costs evolve.
Independent forecasts based on July and August CPI‑W place the 2027 COLA around 3%–4%, with consensus near 3.4%–3.6%.
Rising energy prices could nudge the final COLA higher, but elevated shelter inflation (about 3% year over year) makes a drop below 3% unlikely.
A larger COLA won’t fully offset cost pressures for many retirees because retiree budgets are more exposed to healthcare, housing, groceries, and energy.
Administration calculates next year's cost‑of‑living adjustment (COLA) using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI‑W) for July, August, and September. July and August numbers are already published, so only September remains. With two of the three inputs set, independent estimates are converging.
How September could change the final COLA
September is the only remaining variable before the SSA announces the official number on Oct. 14, 2026. Energy prices have been rising amid conflict in the Middle East and disruptions tied to strikes on oil facilities, and fuel cost increases typically feed into other prices with a lag. That lag means July and August CPI‑W figures may not fully reflect recent energy-driven inflation, so September could push the COLA somewhat higher.
At the same time, shelter inflation has risen about 3% year over year. Because shelter is a large component of CPI measures, sustained housing inflation makes a substantial downward swing in the COLA unlikely even if energy prices drop. AARP's vice president for financial security noted that with only one month of data left, there's less uncertainty and a mid‑3% COLA is the most likely outcome unless September brings dramatic change.
Why a larger COLA may still fall short for many retirees
A bigger COLA increases monthly benefits in nominal terms, but it doesn't guarantee improved buying power for retirees. Healthcare costs, including anticipated rises in Medicare Part B premiums, are expected to outpace overall inflation. The CPI‑W tracks urban wage earners and clerical workers rather than typical senior spending patterns, and older Americans tend to spend a larger share of their budgets on groceries, energy, housing, and healthcare — categories where price pressures remain notable.
Practical takeaway for beneficiaries
Plan for a modestly larger Social Security check in 2027, likely in the mid‑3% range, but don't assume that increase will fully cover rising outlays. Watch the Bureau of Labor Statistics release for September CPI‑W and the SSA announcement on Oct. 14 to know the exact COLA. Consider reviewing Medicare costs and household expense categories most affected by inflation to see whether adjustments to budgets or benefits elections are warranted.
