Social Security's cost-of-living adjustment for 2027 is currently estimated 3.5% to 3.6%. This range comes from multiple separate projections as of September 14, 2026. The New York Times has released a forecast of 3.6%. The Senior Citizens League forecasts a 3.5% rise. ConsumerAffairs also projects 3.5%. All sources indicate comparable forecasts for the COLA.

The Social Security Administration plans to release its formal statement in about one month. The exact date remains unclear, but it is hoped for soon. Beneficiaries will learn the final COLA percentage for 2027 payments.
