Overview
- Independent forecasts cluster at roughly 3.4–3.6 percent for the 2027 COLA, with analyst Mary Johnson at about 3.4% and the Senior Citizens League at about 3.6%.
- The Social Security Administration will compute the COLA from the average CPI‑W for July, August and September and publish the official rate on Oct. 14, 2026.
- Current estimates are provisional because August and September CPI‑W readings can change the final number and fall decisions on Medicare Part B and Part D premiums could reduce beneficiaries’ net gains.
- A mid‑3% increase would add roughly $70 a month to the average benefit but would cover only a small share of high local costs such as New York City rent and could be largely offset by higher drug or premium charges.
- Longer term, the 2026 Trustees Report projects trust‑fund strain by 2032, which keeps pressure on lawmakers to consider benefit or COLA changes and leads advisers to generally recommend delaying claims to raise the base benefit and compound future COLAs.
