Social Security beneficiaries could be heading toward a history-making raise in 2027. Early projections suggest next year's cost-of-living adjustment (COLA) may mark the sixth-straight annual increase of at least 2.5%, something not seen since 1997.

But even after several years of above-average increases, many seniors' checks still aren't keeping pace with essential costs, raising concerns about long-term financial fitness.

Here's what's driving the increase and why retirees may still feel squeezed.

What is the Social Security COLA?

The Social Security COLA is an annual adjustment designed to help benefits keep up with inflation. Without it, rising prices would steadily reduce retirees' purchasing power over time.

COLAs are typically announced each October and take effect in January of the following year. About 75 million Americans rely on these adjustments to help offset rising living costs.

How the COLA is calculated

Since 1975, Social Security has used the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W, to calculate COLAs.

The SSA compares average CPI-W readings from July, August, and September against the same period from the prior year. If inflation rises, benefits increase by the same percentage, rounded to the nearest tenth of a percent.

The 2027 COLA may make history

If current projections hold, 2027 may mark the sixth consecutive year in which Social Security benefits increased by at least 2.5%. The last time that happened was from 1988 through 1997, nearly 30 years ago.

A sixth consecutive year at or above 2.5% would be a genuine milestone for the program, even if the circumstances driving it aren't cause for celebration.

Current estimates are higher than expected

Projections for the 2027 COLA range from 3.9% to 4.2%. The Senior Citizens League has recently projected 3.9%, while independent Social Security and Medicare policy analyst Mary Johnson puts her estimate at 4.2%.

At 3.9%, the average retired worker's monthly benefit would rise by $81, from $2,081.16 to $2,162.32. At 4.2%, the increase would be more meaningful.

Retirees have already seen several large increases

The last five years have already produced unusually high Social Security adjustments. Benefits rose by 5.9% in 2022, 8.7% in 2023, 3.2% in 2024, 2.5% in 2025, and 2.8% in 2026.

The 8.7% increase in 2023 was the largest percentage jump in more than four decades, highlighting how severe inflation became after the pandemic period.

Rising energy prices are driving inflation higher

The sharp upward revision in COLA projections traces directly to Iran's closure of the Strait of Hormuz. Gas prices in the U.S. spiked signficantly between February and March 2026 alone.

As fuel and transportation costs rose, overall inflation followed, with the trailing 12-month inflation rate jumping to 3.3%. Because the CPI-W is weighted heavily toward gasoline, that energy spike feeds directly into the COLA calculation.

A larger COLA does not always mean more buying power

While larger checks sound encouraging, many retirees continue struggling with rising costs. That's because inflation often outpaces the categories seniors spend the most money on. Housing, insurance, and health care costs have remained stubbornly high, even when inflation appeared to cool.

Worse, COLAs are calculated on trailing data. If inflation accelerates after the COLA is set in October, beneficiaries could lose purchasing power mid-year with no adjustment until the following January.

Social Security has lost purchasing power since 2010

According to TSCL's 2024 Loss of Buying Power report, Social Security income has lost approximately 20% of its purchasing power since 2010. What $100 in Social Security income bought in 2010 only purchases $80 worth of the same goods and services today. This erosion continues despite multiple years of above-average COLAs.

The CPI-W problem: It's measuring the wrong people

As of 2024, 80% of Social Security beneficiaries were age 62 or older, yet the CPI-W tracks the spending habits of working-age Americans.

Seniors spend a higher share of their monthly budget on shelter and medical care than working-age people do. The CPI-W doesn't account for this. A more accurate measure, the CPI-E, which tracks elderly spending patterns, has been proposed for years but never adopted for official COLA calculations.

Medicare premiums eat into every COLA

For Medicare enrollees, Part B premiums are deducted directly from benefits. In 2026, the standard Part B premium rose from $185 to $202.90 per month, a nearly 10% increase.

At a 2.8% COLA, the average monthly benefit rises by roughly $57. But if Part B premiums increase again in 2027, a meaningful share of that increase would be absorbed before it reaches a retiree's bank account.

What a historic streak actually means for retirees

Six straight years of at least 2.5% COLAs is historically unusual, but much of that streak reflects persistently high inflation. Larger checks help offset rising prices, yet they do not necessarily improve retirees' financial position.

TSCL Executive Director Shannon Benton noted that many senior households live on only about 58% of the income earned by working-age households, highlighting the broader financial pressure many retirees still face.

Bottom line

The 2027 Social Security COLA is on track to make history, potentially marking six consecutive years of increases above 2.5% for the first time since 1997.

Still, bigger checks do not automatically translate into stronger financial security. Many retirees may need to supplement Social Security benefits with investment income or part-time work, since inflation in health care and housing continues outpacing the benefits many seniors receive.
