The Latest Inflation Report Just Hinted at the 2027 Social Security COLA

Millions of Americans who depend on Social Security benefits for seniors in their retirement might see an increase in their 2027 benefits. New Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) data from July indicates inflation increased between July 2025 and July 2026, suggesting the cost-of-living adjustment (COLA) might give benefits a boost next year.

Although the final COLA won't be announced for several months, this data provides the first concrete look at the inflation figures used to calculate the potential increase.

Why the July monthly inflation report matters to seniors

The COLA helps ensure that Social Security benefits keep up with inflation, so the benefits retain their purchasing power. The COLA calculation is based on CPI-W data from the third quarter, which measures inflation. Each year's data is compared with the CPI-W data from the same quarter of the previous year. If inflation has increased, a COLA, which is a percentage increase, is applied to Social Security benefits payable in January of the following year.

Since the COLA calculation is only based on third-quarter data, only CPI-W reports for July, August, and September are used. All of the inflation activity that takes place earlier in the year doesn't affect the COLA. Though major forecasters have been projecting the 2027 COLA for months, the July CPI-W report is the first concrete piece of information that should actually be used in the calculation.

Where the major COLA forecasters now land

The sharp inflation swings that have occurred so far in 2026 have posed a challenge for COLA forecasters, prompting them to frequently revise their projections. Inflation began at 2.2% in January, reached 4.4% in May, and fell to 3.5% in June.

Now that data has been released for July, forecasters are again revising their projections and are using data that should actually be included in the official calculation. In July, the Senior Citizens League, a nonpartisan senior group, projected a COLA of 3.8%. After July data was released, the Senior Citizens League revised its projection to 3.6%.

As inflation soared earlier this year, independent Social Security analyst Mary Johnson projected a 2027 COLA of 4.7%. Since inflation has cooled, Johnson revised her projection to 3.4%.

An August AARP analysis of inflation data lands at 3.5%, right in between the two projections.

How the COLA might affect Americans

More than 75 million Americans receive Social Security benefits, including many people who heavily depend on the benefits. According to the Center on Budget and Policy Priorities, Social Security keeps 23.5 million adults and children in the United States above the poverty line.

For some retirees, Social Security benefits help bridge a gap between retirement savings and costs. For others, Social Security functions as a sole source of income, though figures on that population vary. A 2025 Transamerica Center for Retirement Studies survey reported that 53% of retirees named Social Security as their primary source of income. An Investopedia tabulation of the March 2025 Current Population Survey revealed that 24% of Americans age 65 and older responded that 90% or more of their household income came from Social Security.

Is a large COLA a positive for retirees

Retirees who largely depend on Social Security benefits may be particularly vulnerable to the impacts of inflation. A larger COLA helps keep up with a large climb in inflation, but it's not necessarily a positive. A large COLA means that costs are increasing. Though retirees may get a larger monthly check, that amount is likely to be fully consumed by their higher costs.

The COLA is only based on third-quarter data, so if inflation costs climb in the first and second quarters but drop in the third, retirees may have had to pay higher expenses for six months without a correlating benefits adjustment. If inflation steeply climbs in the fourth quarter, that inflation isn't reflected in the next year's COLA, and retirees may find that benefits come up short compared to their actual expenses.

Does the COLA accurately reflect retirees' expenses

The 2027 COLA projections indicate it may be larger than the 2.8% COLA that went into effect for 2026 benefits, but even a larger COLA might not keep pace with the specific expenses retirees face.

CPI-W data reflects expenses that workers typically face, but the budgets of older Americans are different. Older Americans often spend more on expenses like health care and housing, and these categories often increase in cost faster than overall inflation rates. A larger COLA still might not keep up with these particular types of expenses, leaving seniors to make up the difference.

Bottom line

At this time, the COLA calculation still depends on two months of data that hasn't yet been released, so all projections are still just guesses. The remaining two months of data may still shift the COLA, so this is an issue that Social Security recipients may want to monitor. The Social Security Administration generally releases the official COLA in October.

Inflation has driven up many costs this year, so this may be a good time to check in on your retirement plan and potentially revise your budget regardless of whether benefits increase in 2027 or not.
