Senior Citizens League Projects 3.8% Social Security COLA for 2027

The Senior Citizens League projects a 3.8% cost-of-living adjustment (COLA) for Social Security benefits in 2027. This figure is one percentage point higher than the 2026 adjustment and exceeds the 50-year average. Based on an average retirement benefit of $2,084 per month as of June 2026, a 3.8% increase would raise monthly payments to $2,163.

The Social Security Administration is scheduled to announce the official 2027 COLA on October 14, 2026, with personalized notices sent to beneficiaries in December. The final percentage remains dependent on inflation trends over the coming months.

Parallel to these projections, the Committee for a Responsible Federal Budget (CRFB) and the Urban Institute analyzed a flat-rate COLA proposal. This mechanism would cap benefit growth for high earners by pegging adjustments to the 20th or 30th percentile of beneficiaries. The CRFB reports that a flat-rate COLA at the 20th percentile could reduce the 75-year fiscal shortfall by 50% and delay the projected 2032 insolvency of the trust funds by two years.

Maya MacGuineas, president of the CRFB, warned that the effectiveness of such reforms diminishes over time. She noted that the same plan would have achieved solvency through 2071 if adopted in 1987, but now only delays insolvency by two years.
