2027 Social Security COLA could hit 3.6%: How Medicare costs may cut into the increase
Social Security recipients await the 2027 COLA announcement
Social Security beneficiaries could be in line for a bigger increase in 2027, with a new projection putting next year’s cost-of-living adjustment at 3.6%.
The estimate, released by AARP after the latest inflation data, would make the 2027 Social Security COLA the largest annual increase since 2023 if it holds. But the headline percentage does not tell the whole story for retirees.
Higher Medicare premiums, prescription drug costs and other expenses could absorb part of the increase, meaning the amount beneficiaries actually feel in their monthly budgets could be considerably smaller.
The official 2027 Social Security COLA will not be announced until October, when the government releases the September inflation figures used to complete the calculation.
2027 Social Security COLA Projection Reaches 3.6%
The latest projection puts the 2027 COLA at 3.6%, compared with the 2.8% increase awarded for 2026.
The adjustment is based on inflation data rather than a discretionary decision by the Social Security Administration. The government uses the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W, to determine the annual increase.
Three months of inflation data — July, August and September — are used in the calculation. With July and August figures already available, analysts can make a stronger estimate of where the final COLA is heading.
AARP’s 3.6% projection could still change when September’s inflation number is released.
That leaves beneficiaries watching the final inflation data closely, particularly because energy prices have the potential to push the final figure higher.
When Will the Official 2027 Social Security COLA Be Announced?
The official 2027 Social Security COLA is expected to be announced on October 14, 2026, when September inflation data are released.
The timing matters because the September CPI-W figure completes the three-month calculation used for the adjustment.
If the final calculation matches the current projection, Social Security checks would receive a 3.6% increase in 2027.
Beneficiaries should treat the 3.6% figure as a projection rather than a guaranteed increase until the government makes the official announcement.
How Much Could Social Security Checks Increase in 2027?
The dollar impact will depend on the size of each person’s benefit.
Using the average monthly retirement benefit of about $2,085, a 3.6% COLA would produce an increase of roughly $75.06 per month.
That would take the average benefit to approximately $2,160.06 before other deductions.
The calculation is straightforward:
$2,085 × 3.6% = $75.06
But the gross increase is not necessarily the amount retirees will see added to their bank accounts.
Medicare premiums and other deductions can reduce the net increase.
Medicare Premiums Could Take a Bite Out of the COLA
One of the biggest questions surrounding the 2027 Social Security increase is what happens to Medicare Part B premiums.
Medicare trustees have projected that the standard Part B premium could increase by $6.60 per month in 2027, reaching $209.50.
If that projection holds, a beneficiary receiving the average retirement payment could see a $75.06 monthly Social Security increase, while $6.60 of that could effectively be offset by the higher Medicare premium.
That would leave an estimated net increase of about $68.46 per month, before considering other deductions or individual circumstances.
The result would be a net increase of roughly 3.28% for someone receiving the average benefit used in the calculation.
That distinction matters for retirees who rely heavily on Social Security to cover housing, food, utilities and medical expenses.

Why the 2027 COLA May Not Feel Like a 3.6% Raise
The Social Security COLA is designed to help benefits keep pace with inflation. But the inflation measure used to calculate it does not necessarily reflect the spending patterns of older Americans.
CPI-W tracks the prices paid by urban wage earners and clerical workers. Critics have long argued that it does not fully capture the expenses faced by retirees.
Healthcare is a major concern.
Older Americans can devote a larger share of their budgets to medical care, prescription drugs and other health-related expenses. If those costs rise faster than the overall inflation measure used for Social Security, a higher COLA may not translate into the same increase in purchasing power.
That is why the 2027 COLA projection needs to be viewed alongside Medicare premiums and healthcare inflation rather than as a standalone figure.
2027 COLA Would Be the Biggest Increase Since 2023
If the 3.6% estimate becomes official, it would represent the strongest Social Security COLA since 2023.
The 2023 adjustment was 8.7%, reflecting the unusually high inflation that followed the pandemic-era price surge.
The COLA then fell to 3.2% in 2024 and 2.5% in 2025 before rising to 2.8% for 2026.
A 3.6% increase would signal another step upward after several years of more moderate adjustments.
It would also give beneficiaries a larger nominal payment at a time when many household expenses remain elevated.
What Retirees Should Watch Before the Final Announcement
The biggest number to watch is the September CPI-W reading.
That figure will complete the three-month period used to calculate the official COLA. Energy prices could also play a role in the final result, particularly if higher oil prices push inflation higher during September.
Medicare’s final Part B premium announcement will be another important number.
For beneficiaries, the more useful calculation is not simply “How much will my Social Security check increase?” but “How much will I have left after Medicare and other costs?”
A 3.6% COLA could provide meaningful additional income, but the real financial effect will vary from one household to another.
What a 3.6% COLA Means for Social Security Beneficiaries
For retirees and other Social Security recipients, the projected increase would provide additional monthly income beginning in 2027.
Someone receiving $1,500 per month would gain about $54 under a 3.6% COLA.
A $2,000 monthly benefit would increase by about $72.
Someone receiving $2,500 would see an increase of about $90.
Those figures are before Medicare premiums, taxes or other deductions.
The projection also does not mean every Social Security beneficiary will receive the same dollar increase. The percentage is applied to individual benefit amounts.
The Bigger Question Behind the 2027 COLA
A 3.6% Social Security increase would give millions of beneficiaries more money each month, but the percentage alone does not determine whether retirees are financially better off.
The combination of Social Security benefits, Medicare premiums, healthcare expenses, housing costs and inflation will determine how much additional purchasing power beneficiaries actually gain.
That makes the October announcement only part of the story. Once the official COLA and Medicare costs are known, retirees will have a clearer picture of how much their monthly budgets could change in 2027.
