Social Security Faces 3 Historic Milestones With Its 2027 COLA

A bigger Social Security raise could be coming in 2027, and the latest estimate would put it in some interesting company. The Senior Citizens League now projects a 3.6% COLA after the first inflation reading used in the calculation came in slightly cooler than expected.

If that estimate holds, the 2027 COLA would be the third highest in the last decade and come in around the long-term average since automatic adjustments began in 1975. It would also tie for the 18th-highest automatic COLA of the modern era.

For anyone living on just Social Security, those milestones sound encouraging, but the real test will be whether the extra money keeps up with the bills retirees are paying.

How the 2027 COLA compares with the past decade

Social Security raises were much smaller for several years before the recent run of higher inflation. Retirees received no COLA at all in 2016, followed by just 0.3% in 2017 and 1.3% in 2021.

Inflation later pushed COLAs sharply higher, including 5.9% in 2022 and 8.7% in 2023. Since then, the increases have gradually come back down:

• 2024: 3.2%
• 2025: 2.5%
• 2026: 2.8%

A 3.6% COLA for 2027 would break that recent downward run and come fairly close to the roughly 3.7% average for automatic COLAs since they began in 1975.

The Senior Citizens League had been projecting 3.8%, but lowered its estimate to 3.6% after July inflation data came in on August 12. The final COLA will still depend on the August and September readings, so retirees won't know the official number until October.

What's pushing the COLA estimate higher

Energy prices are a big reason the 2027 COLA estimate is running above the increases retirees saw in the past couple of years. Gasoline was about 25% more expensive in July than a year earlier, and fuel oil was up roughly 39%.

Gas prices also have a little more influence on Social Security's COLA than they do on the inflation number most people hear about. Energy makes up about 8.1% of the CPI-W used for COLAs, compared with about 6.4% of the broader CPI-U. So when fuel costs jump, they can push your projected Social Security raise higher too.

What a 3.6% COLA could add to your check

On an average retired-worker benefit of about $2,086 a month, a 3.6% COLA would add roughly $75 before Medicare or tax withholding. Over a full year, that comes to about $900.

You may not see that entire $75 in your bank account, though. Most retirees have their Medicare Part B premium taken directly from Social Security, and the 2027 premium won't be announced until later this fall. If it goes up, some of your COLA could go toward covering that increase.

For comparison, the standard Part B premium is $202.90 a month in 2026, so that $900 annual raise would be enough to cover more than four months of today's premium.

Why retirees could still be behind after a 3.6% raise

A 3.6% COLA would certainly help, but retirees have already lost ground to rising prices over the past decade. The Senior Citizens League estimates that Social Security benefits have lost about 13.7% of their buying power since 2016.

Its research found that expenses common among retirees rose about 43.5% over that period, compared with roughly 37.6% for the CPI-W used to calculate Social Security COLAs. Those small yearly gaps can build over time and leave benefits trailing the costs retirees actually face.

The group estimates it would take about a 15.7% increase to fully catch up, or roughly $296 more a month for the average beneficiary.

A 3.6% COLA would give retirees some welcome help with today's expenses, but it wouldn't make up for everything their benefits have lost over the years.

Why the COLA may not match your own expenses

The CPI-W used for Social Security COLAs was designed around working households, so it gives more weight to costs like gasoline and transportation than many retirees may spend each month.

Medical care, for example, makes up about 7.6% of the CPI-W, compared with roughly 8.4% of the broader CPI-U.

If you drive less but spend more on health care, your own costs may rise differently from the index behind your COLA. A jump in gas prices could push the COLA higher even if fuel takes up only a small part of your budget.

What could still change before October

The 3.6% projection is based on July, the first of the three months used to calculate the 2027 COLA. July's CPI-W came in at 3.4% year over year, bringing the estimate down from the earlier 3.8%.

Two inflation reports are still to come:

• August data: Scheduled for September 11
• September data: Scheduled for October 14

Once that final report arrives, Social Security will have what it needs to calculate the official COLA.

Note that energy prices could still move the estimate in either direction. Gasoline was about 25% more expensive than a year earlier in July, so another jump in fuel costs could push the COLA higher. If inflation cools further, the final increase could come in below 3.6%.

Bottom line

A 3.6% COLA would give retirees a bigger raise than they received this year and put the increase close to Social Security's long-term average. It may not make up for every dollar of buying power lost over the years, but it could still give your monthly budget a little more breathing room in 2027.

The final increase will depend on where inflation goes over the next two months, with the official number coming in October. Once you know exactly how much your benefit will rise, you can make the right moves for your 2027 budget and decide where those extra dollars can help most.
