The Senior Citizens League Forecasts 3.5% Social Security COLA for 2027

How the 2027 Social Security COLA is Calculated

Social Security’s cost-of-living adjustment is determined by comparing the average Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) across July, August, and September of the current year to the same three-month period from the prior year. The Bureau of Labor Statistics releases the September CPI data to finalize this calculation. Advocacy group The Senior Citizen League issued a forecast putting the 2027 COLA at 3.5%, which marks the highest level in four years. That projection sits down 0.1 percentage points from the group’s previous estimate, but remains well above the 2.8% COLA for 2026 and the 2.5% adjustment implemented in 2025. If the 3.5% forecast holds true, the average monthly benefit would rise by $73, lifting payments from $2,086 to $2,159.

Current Benefit Averages Across States

Average monthly payments vary significantly by geographic location. Across the country, the current average retirement benefit stands at $2,086 a month, translating to roughly $25,000 per year. State-level data shows the highest average monthly payments are concentrated in New Jersey at $2,256, followed closely by Connecticut at $2,249, and Delaware at $2,225.

Factors Determining Individual Benefit Amounts

Individual monthly check amounts depend directly on lifetime earnings history, the age at which a worker retires, and when they choose to start drawing benefits. According to the Social Security Administration, there is no simple maximum amount that covers everyone, because payments reflect individual earnings records and retirement timing. To calculate a monthly benefit, the Social Security Administration averages a worker’s 35 highest-earning years and adjusts the figure for inflation, meaning higher lifetime earnings yield higher benefits.

Retirement Age and Claiming Rules

A worker’s birth year dictates the exact age they reach Full Retirement Age to claim 100% of their calculated benefits. For individuals born after 1960, the full retirement age is currently set at 67. Beneficiaries can start claiming reduced payments as early as age 62, though benefits drop by one-half of 1% for each month claimed prior to reaching full retirement age. Conversely, delaying collection past full retirement age up until age 70 earns beneficiaries an increased payout of about 8% for each year waited.
