Social Security beneficiaries could see a larger cost-of-living adjustment in 2027, with early estimates pointing to an increase of up to 3.8%. The projection is not final, but it offers beneficiaries a useful indication of how their monthly payments could change next year.
The Senior Citizens League (TSCL) currently estimates a 3.8% COLA for 2027, up from the 2.8% adjustment announced for 2026. AARP has offered a slightly lower projection of 3.6%.
With more than 71 million Americans receiving Social Security benefits, even a small percentage change can affect household budgets. The average monthly benefit for retired workers was close to $1,938 in June 2026, according to Social Security Administration data.
If the final COLA were 3.8%, an average monthly benefit of $1,938 would increase by about $73.64, bringing the payment to roughly $2,011.64.
Calculate
A 3.8% increase would add different amounts depending on your current Social Security payment.
| Current Monthly Benefit | 3.8% Increase | Estimated New Benefit |
|---|---|---|
| $1,000 | $38.00 | $1,038.00 |
| $1,500 | $57.00 | $1,557.00 |
| $1,938 | $73.64 | $2,011.64 |
| $2,000 | $76.00 | $2,076.00 |
| $2,500 | $95.00 | $2,595.00 |
| $3,000 | $114.00 | $3,114.00 |
| $3,500 | $133.00 | $3,633.00 |
To estimate your potential increase, multiply your current monthly benefit by 0.038. Then add that amount to your current payment.
For example, someone receiving $2,000 per month would receive an estimated $76 increase if the final COLA were 3.8%. Their new monthly benefit would be approximately $2,076.
These are estimates only. The actual increase will depend on the official COLA announced by SSA.
Timing
The 3.8% figure is not the final 2027 COLA. Social Security calculates the annual adjustment using inflation data from the third quarter.
The formula compares the average Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) during July, August, and September with the corresponding average from the previous year.
The official COLA is generally announced by SSA in October. Until those inflation figures are available, advocacy group projections can move higher or lower.
Alex Moore, a statistician with The Senior Citizens League, said economic conditions could still influence the estimate. Energy prices are one factor to watch because changes in fuel costs can affect broader inflation.
If inflation pressures ease, the eventual COLA could be below the current 3.8% projection. If prices continue rising, the adjustment could potentially be higher.
Medicare
The size of the Social Security COLA is only part of the calculation for many older Americans. Medicare costs can also affect how much money beneficiaries actually have available each month.
The standard Medicare Part B premium increased to $202.90 per month in 2026, up from $185 in 2025, according to the Centers for Medicare & Medicaid Services.
That represented a 9.7% increase, which was considerably higher than the 2.8% Social Security COLA for 2026.
For beneficiaries enrolled in Medicare Part B, the premium is generally deducted directly from their Social Security payment. As a result, a higher Social Security benefit does not necessarily translate into the same increase in money available for other household expenses.
Health care costs remain an important concern for people living on fixed incomes. Rising premiums, prescription expenses, dental care, medical services, and other costs can reduce the purchasing power of a COLA increase.
Proposal
Congress has also considered changing how Social Security calculates its annual COLA.
The Social Security 2100 Act would replace the current CPI-W measure with the Consumer Price Index for the Elderly, commonly called CPI-E.
CPI-E is designed to reflect spending patterns among people age 62 and older. The index gives greater weight to categories such as medical care and housing, which can represent a larger share of spending for older households.
Supporters of using CPI-E argue that the current inflation measure may not fully reflect the expenses faced by older Americans.
The Senior Citizens League has pointed to differences in spending patterns between seniors and the broader working population. Health care and housing costs, in particular, can have a significant effect on retirees’ household budgets.
History
The Social Security 2100 Act was first introduced by U.S. Rep. John Larson in the House of Representatives in July 2014. Versions of the legislation have been reintroduced during later sessions of Congress.
The proposal has not become law. Therefore, Social Security’s current COLA calculation remains based on the existing formula unless Congress passes legislation changing it.
For now, beneficiaries should treat the 3.8% estimate as a projection rather than a confirmed increase. The final number will depend on inflation data collected during the third quarter of 2026.
A 3.8% COLA would provide a noticeable increase for many recipients, but the effect on household finances will depend on individual benefit amounts and other expenses, particularly Medicare and health care costs. Beneficiaries can use their current monthly payment to estimate the potential change, while keeping in mind that the official 2027 adjustment will not be known until the SSA announces it.
