Overview
Millions of Americans receiving Social Security benefits could see their monthly payments increase by approximately $73–$75 in 2027, according to the latest inflation-based projections ahead of the official cost-of-living adjustment (COLA) announcement.
The Senior Citizens League (TSCL) forecasts a 3.5% increase, while other estimates indicate a possible 3.6% adjustment. Either figure would exceed the 2.8% increase implemented for 2026 and represent the largest annual adjustment since 2023.
- Social Security’s 2027 cost-of-living adjustment is projected at 3.5%–3.6%, potentially increasing average monthly retirement benefits by approximately $73–$75.
- The official 2027 COLA will be determined on October 14, 2026, following the release of September inflation data. Approximately 75.9 mn Americans received Social Security, Supplemental Security Income or both as of August.
- Rising healthcare, energy and grocery costs could offset some of the increase. Medicare Part B premiums are projected to reach $209.50 per month in 2027, compared with $202.90 in 2026.
The Social Security Administration is expected to announce the final rate on October 14, 2026, after the Bureau of Labor Statistics publishes September consumer price data at 8:30 a.m. Eastern Time.
How much will Social Security benefits increase in 2027?
Based on the average retired worker benefit of $2,087.52 in August 2026, a 3.5% adjustment would add approximately $73.06 per month, bringing the payment to $2,160.58. A 3.6% increase would add roughly $75.15 monthly, or about $902 annually.
Actual increases will vary according to individual benefit amounts. Retirees receiving higher payments generally receive larger dollar increases because the adjustment is calculated as a percentage of existing benefits.
According to Social Security Administration data, approximately 75.9 mn Americans received Social Security benefits, Supplemental Security Income (SSI), or both in August 2026.
The annual adjustment is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). Specifically, the government compares the average index level for July, August and September with the corresponding three-month period in the previous year.
July and August inflation figures are already available, leaving September as the final component of the 2027 calculation.
TSCL’s latest forecast of 3.5% follows an earlier estimate of 3.6%. The organization revised its projection downward by 0.1 percentage points after reviewing August inflation figures.
Social Security’s 2027 cost-of-living adjustment is forecast at 3.5-3.6%, above the 2.8% increase for 2026. he Senior Citizens League projects a 3.5% COLA, while AARP expects 3.6%
Why higher Social Security payments may not offset inflation
An increase in nominal benefits does not necessarily translate into greater purchasing power for retirees.
Older Americans face continued pressure from housing, food, energy and medical expenses, which can account for substantial portions of retirement budgets.
In TSCL’s 2026 survey, 89% of older respondents said the 2026 COLA was insufficient and expected their benefits to fall behind inflation. The survey also found that 44% relied entirely on Social Security for their income (see Why did you get $90 from Social Security? Who qualifies for payment).
One concern is that the CPI-W reflects the spending patterns of urban wage earners rather than retirees, whose budgets may contain a higher proportion of healthcare and other age-related expenses.
Medicare premiums present an additional consideration. The 2026 Medicare Trustees Report projects the standard Part B monthly premium will increase from $202.90 to $209.50 in 2027.
That $6.60 monthly increase would absorb part of the projected Social Security adjustment for beneficiaries whose Medicare premiums are deducted directly from their payments. The final 2027 premium has not yet been established.
Social Security faces funding pressure beyond 2027
The upcoming adjustment also arrives amid concerns about the program’s long-term financing.
According to the 2026 Social Security Trustees Report, reserves in the Old-Age and Survivors Insurance Trust Fund are projected to be depleted in the fourth quarter of 2032.
Without legislative changes, continuing income would cover approximately 78% of scheduled retirement and survivor benefits at that point (71% of Medicare Advantage members in 4-star or higher drug plans for 2027).
The combined Social Security retirement and disability trust funds are projected to have sufficient reserves until 2034, when continuing income would cover approximately 83% of scheduled benefits.
These are projections under current law, not announced benefit reductions.
For current beneficiaries, the immediate question is the size of the 2027 COLA. A 3.5% adjustment would provide approximately $877 in additional annual income for the average retired worker receiving $2,087.52 per month, before any changes in deductions.
The final increase will depend on the September CPI-W figure scheduled for release on October 14.
