- Social Security recipients will learn the size of their 2027 cost-of-living adjustment on Wednesday, October 14, with current forecasts pointing to an increase of roughly 3.5% to 3.6% as retirees continue to face pressure from housing, food and healthcare costs.
The Social Security Administration is expected to announce the 2027 cost-of-living adjustment (COLA) on Wednesday, October 14, after the Bureau of Labor Statistics releases September inflation data. The adjustment will determine how much monthly Social Security and Supplemental Security Income benefits increase next year.
Forecasts from retirement advocacy groups suggest the increase could be between 3.5% and 3.6%, above the 2.8% adjustment for 2026. The final percentage has not yet been announced, however, and will depend on the inflation figures used in the statutory calculation.
The Social Security Administration’s official COLA information confirms that the next adjustment will be announced in October. The agency calculates the annual increase using changes in the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W.
The announcement matters to millions of Americans who rely on retirement, disability or survivor benefits to cover everyday expenses. The increase is intended to help payments maintain their purchasing power as prices rise, although the adjustment may not match the cost increases experienced by every household.
Latest 2027 Social Security COLA forecast outlines the estimates published before the official announcement. Those projections remain estimates until the government releases the final figure.
How Much Could Social Security Payments Increase in 2027?
The Senior Citizens League projected a 3.5% COLA in its September forecast, while AARP’s estimate was around 3.6%, according to recent reporting on the upcoming announcement.
If the final adjustment is 3.5%, a beneficiary receiving $2,000 per month would see an increase of $70, bringing the monthly payment to $2,070 before deductions. At 3.6%, the same benefit would rise by $72 to $2,072.
For someone receiving $2,500 monthly, a 3.5% increase would add $87.50, while a 3.6% adjustment would add $90. These examples illustrate the effect of the projected percentages; individual benefit increases will depend on each recipient’s current payment and the final COLA.
The 2026 COLA was 2.8%, following a 2.5% increase in 2025. A 2027 adjustment of 3.5% or 3.6% would therefore be the largest annual increase since 2023, when beneficiaries received an 8.7% adjustment.
The formula uses the average CPI-W for July, August and September of the current year and compares it with the average for the third quarter of the last year in which a COLA was established. The September reading is the final piece needed to calculate the 2027 increase.
The Bureau of Labor Statistics’ Consumer Price Index release calendar lists the September inflation report for October 14. Until those figures are available and the SSA publishes its calculation, the 3.5%–3.6% range should not be treated as a confirmed benefit increase.
The COLA applies to Social Security retirement, disability and survivor benefits, as well as Supplemental Security Income. The payment schedules differ, however, so recipients should not assume every benefit will arrive on the same date.
When the 2027 Increase Will Take Effect and What Could Reduce It
The new Social Security COLA will generally apply to benefits payable in January 2027. Eligible Supplemental Security Income recipients typically receive their adjusted payment earlier, with the January benefit scheduled for December 31, 2026, because January 1 is a federal holiday.
Recipients generally do not need to apply for the annual increase. The adjustment is applied automatically to eligible benefits, and the SSA provides personalized information through its online services.
The amount deposited into a beneficiary’s bank account may be lower than the gross increase suggests if Medicare premiums or other deductions rise. This is particularly relevant for retirees enrolled in Medicare Part B, whose premiums are commonly deducted directly from Social Security payments.
The Centers for Medicare & Medicaid Services has projected that the standard monthly Medicare Part B premium will rise from $202.90 in 2026 to $209.50 in 2027. That would represent an additional $6.60 per month, although the net effect on an individual’s Social Security payment will depend on the person’s circumstances.
Beneficiaries can review projected Medicare Advantage premiums for 2027 to understand how Medicare costs may change next year. Medicare Advantage premiums and the standard Part B premium are different charges, so a decline in the average price of one type of plan does not mean every Medicare expense will fall.
Eligible beneficiaries should also distinguish regular benefit adjustments from one-time assistance. The recently reported one-time $90 Medicare premium rebate is separate from the annual Social Security COLA and does not create a permanent monthly increase.
The broader issue is whether the adjustment will keep pace with the expenses retirees actually face. The official formula measures changes in prices using CPI-W, an index designed around urban wage earners and clerical workers. Some senior advocates argue that an index reflecting older Americans’ spending patterns more closely would better capture the effects of healthcare and housing costs.
For now, recipients should wait for Wednesday’s announcement before adjusting their 2027 budgets. The final percentage will establish the gross benefit increase, while Medicare premiums and other deductions will determine how much of that increase reaches beneficiaries’ accounts.
