Early Forecasts Put 2027 Social Security COLA Near 3.8%

Overview

• Analysts and advocacy groups in late July and early August estimated the 2027 cost-of-living adjustment at roughly 3.7–3.8%, but the Social Security Administration will set the final figure in October.
• The COLA is calculated from the CPI‑W average for July through September, so the July Consumer Price Index released on Aug. 12 and the Labor Department's September CPI‑W reading are the key near-term inputs.
• Recent spikes in oil prices tied to renewed Middle East fighting and low Strategic Petroleum Reserve levels have pushed short-term inflation forecasts higher and helped lift early COLA projections.
• Any nominal COLA increase can be partly or fully offset by higher Medicare Part B premiums, which are deducted from benefits and have risen sharply in recent years.
• More than 54 million retired‑worker beneficiaries depend on the annual COLA, and policy debates over switching to a CPI measure that tracks older Americans' spending remain active as advocates seek better alignment with seniors' costs.
