Social Security's 2025 Cost-of-Living Adjustment (COLA) Is Shaping Up to Be a Double-Edged Sword for Retirees

For most retired Americans, Social Security provides more than just a monthly check. The income they receive forges a financial foundation during their golden years.

Over the last 23 years, national pollster Gallup has surveyed retirees to gauge their reliance on America's leading social program. Consistently, between 80% and 90% of respondents noted they need their Social Security check to cover at least some portion of their expenses, including 88% of those surveyed in April 2024.

With so many aging Americans counting on Social Security to shore up their finances, it should come as little surprise that the annual cost-of-living adjustment (COLA) is the most-anticipated reveal of the year. This unveiling is now less than two weeks away.

While there's a glimmer of hope for beneficiaries, Social Security's 2025 COLA looks to be shaping up as a double-edged sword for retirees.

What is Social Security's COLA and how is it determined?

Social Security's cost-of-living adjustment that you're always hearing about is the "raise" beneficiaries receive most years to account for rising prices -- what's better known as inflation. You'll note that I put "raise" in quotation marks to represent that increases to Social Security benefits are meant to match inflation and not outpace it, which a true raise from an employer may be able to do.

Hypothetically, if the price for a broad basket of goods and services regularly purchased by retirees climbs in price by 3.5% from one year to the next, Social Security benefits should rise by the same percentage to ensure that the same quantity of goods and services can continue to be bought. COLA is effectively the mechanism the Social Security Administration uses to avoid beneficiaries losing buying power.

In the 35 years following the initial mailed retired-worker check (January 1940 through December 1974), there was no rhyme or reason to these adjustments. There was no change to benefits during the entirety of the 1940s, and only 11 COLAs were passed by special sessions of Congress over the other 25 years.

Beginning in 1975, the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) became the program's measure of inflation that was responsible for determining COLAs on an annual basis. Every component to the CPI-W has individual percentage weightings that allow the index to be chiseled down to a single figure each month, which makes for incredibly easy year-over-year comparisons to determine if prices are, collectively, increasing (inflation) or declining (deflation).
