Social Security's cost-of-living adjustment for 2027 is currently estimated 3.5% to 3.6%. This range derives from several independent projections as of September 14, 2026. The New York Times has reported a projection of 3.6%. The Senior Citizens League forecasts a 3.5% rise. ConsumerAffairs further suggests 3.5%. All sources indicate similar expectations for the COLA.

The Social Security Administration is set to issue its formal statement in about one month. The exact date has not been confirmed, but it is hoped for soon. Beneficiaries will learn the final COLA percentage for 2027 payments.
