Quick answer: the 2027 Social Security COLA is forecast at 3.6% to 3.9%

As of Aug. 1, 2026, the 2027 Social Security COLA increase for seniors is still a forecast, not an official number. The useful planning range is now 3.6% to 3.9%. The Senior Citizens League has projected 3.8%, AARP has projected 3.6%, and independent analyst Mary Johnson has projected 3.7% after the June CPI-W data.[1][2][3]

For a person receiving the average retired-worker benefit of about $2,084 a month, the named 3.6% to 3.8% forecasts work out to roughly $75 to $79 more per month before any Medicare premium change. If you also pencil in the upper 3.9% planning edge, the increase is about $81. Using the commonly cited 3.8% forecast, that same average benefit would rise to about $2,163.[2][4]

If your own Social Security check is higher or lower than the average, use your current gross monthly benefit instead. For a rough estimate, multiply your current monthly benefit by 0.036, 0.037, 0.038, and 0.039. That gives you the current planning band, not the final answer.

A simple example: if your current gross benefit is $1,500, a 3.6% COLA would add about $54 a month, while a 3.9% COLA would add about $59. That is the kind of pencil-and-paper estimate that can help with a January rent, grocery, or prescription budget while everyone waits for the official October number.

Is the 2027 COLA official yet?

No. The official 2027 Social Security COLA has not been announced yet. The Social Security Administration is expected to announce the final COLA on Oct. 14, 2026, after the September inflation report is released.[2][5]

That distinction matters. A forecast can help a household plan, but it is not the figure SSA will put into benefit notices. The current range is narrow enough to be useful for rough budgeting, especially compared with earlier forecast swings.

The Senior Citizens League’s estimate moved from 2.8% in March to 3.9% in April, then to 3.8% from May through July.[1][6] That is not a reason to ignore the current number. It is a reason to label it correctly.

When will the 2027 COLA show up in payments?

The 2027 COLA is expected to first appear in January 2027 Social Security payments.[2][4] For many households, that payment date matters just as much as the percentage.

Current published payment-date reporting points to this January 2027 schedule: Jan. 3 for people who started receiving Social Security before May 1997; Jan. 13 for birth dates on the 1st through 10th; Jan. 20 for birth dates on the 11th through 20th; and Jan. 27 for birth dates on the 21st through 31st. SSI recipients are expected to receive the January 2027 federal SSI payment on Dec. 31, 2026.[3]

Please treat those dates as a planning guide until SSA publishes or confirms its official 2027 payment calendar. If you help a parent manage bills, write the likely date in pencil for now, then check it again once the official SSA calendar is available.

How Social Security calculates the COLA, in plain English

SSA bases the annual COLA on the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W. It compares the average CPI-W for July, August, and September with the average for the same three months a year earlier, then rounds the increase to the nearest one-tenth of 1%.[7]

That is why the final number cannot be known on Aug. 1. July, August, and September CPI-W data still have to be completed before SSA can lock the 2027 COLA.

Why different articles show different “average checks”

Be careful with the phrase “average Social Security check.” It can mean different things depending on the source, the month, and the group being measured.

• AARP uses an average retired-worker benefit of about $2,084 for June 2026 when translating a 3.6% COLA into about $75 more per month.[2]
• The Motley Fool also uses about $2,084 for the average retired-worker benefit and says a 3.8% COLA would raise it to about $2,163.[4]
• CNBC Select cites a different current average benefit figure of $2,026 in its COLA discussion.[3]
• The Senior Citizens League cites an all-beneficiary average of $1,937.53, which is not the same as the retired-worker average.[1]

Those figures are not interchangeable. A retired worker, a spouse, a survivor, and an all-beneficiary average are different bases. If you are estimating your own January check, your own current gross monthly benefit is the cleanest starting point.

Will Medicare Part B reduce the increase?

Possibly. The COLA is a gross benefit increase. Many people have Medicare Part B premiums deducted automatically from their Social Security payments, so the amount that lands in the bank may be smaller than the headline COLA math.

The 2027 Medicare Part B premium is not part of the Social Security COLA formula, and final Medicare premium figures are expected later, typically in November 2026. For now, it is safer to treat the 3.6% to 3.9% range as a gross-benefit estimate, not a guaranteed net-check increase.

FAQ: 2027 Social Security COLA increase for seniors

What is the best current estimate for the 2027 Social Security COLA?

The best current planning range is 3.6% to 3.9%, based on the latest named projections available as of Aug. 1, 2026. The individual forecasts are 3.6% from AARP, 3.7% from Mary Johnson, and 3.8% from The Senior Citizens League.[1][2][3]

How much more per month would that be?

On an average retired-worker benefit of about $2,084, the named 3.6% to 3.8% forecasts mean roughly $75 to $79 more per month before Medicare premium changes. At 3.8%, the increase is about $79, bringing that average benefit to about $2,163. At the upper 3.9% planning edge, the increase would be about $81.[2][4]

When will Social Security announce the official 2027 COLA?

The official announcement is expected on Oct. 14, 2026, after the September CPI-W data are available.[2][5]

When will I receive the higher payment?

The increase should first appear in January 2027 Social Security payments. Depending on your benefit type and birth date, current planning dates are Jan. 3, Jan. 13, Jan. 20, or Jan. 27, 2027. SSI recipients are expected to receive the January 2027 federal SSI payment on Dec. 31, 2026.[3]

Can I use the forecast for budgeting now?

Yes, for rough budgeting. Do not treat it as final. A household can reasonably pencil in a gross increase near the 3.6% to 3.9% range, then update the number after the official Oct. 14 announcement.

What should I write in my January 2027 budget today?

Write your current gross Social Security benefit, then add a low estimate at 3.6% and a high estimate at 3.9%. If your benefit is close to the average retired-worker amount of about $2,084, that means planning for about $75 to $79 more per month using the named forecasts, or about $81 at the upper 3.9% planning edge, before Medicare premium changes. The official number is still pending, but the current range is narrow enough to make a reasonable January cash-flow estimate now.
