Social Security's 3.6% COLA for 2027 Could Be on the Chopping Block

Social Security beneficiaries are set to receive a 3.6% cost-of-living adjustment in 2027, up from 2.8% this year — an extra $75 a month for the average recipient. But that figure assumes Washington leaves the COLA alone, and with the program's trust funds facing depletion within six years, several proposals would change it substantially.

The Social Security Administration ties the annual adjustment to a subset of the Consumer Price Index. The mechanism exists to preserve purchasing power, and analysts describe it as nearly unique among retirement income sources.

"People who receive Social Security benefits rely on [the COLA] heavily to protect their buying power," said Mary Johnson, an independent Social Security and Medicare analyst who has tracked benefit adjustments for almost 30 years. "It is one of the only forms of retirement income we have that offers inflation adjustment." Inflation-protected annuities exist, she noted, but retirees pay for that feature.

How big is the funding gap?

Not enough money flows into the trust funds to sustain the program. Experts expect depletion within six years. If that happens, all beneficiaries face cuts of roughly 26%, and absent legislative change those cuts deepen over time. Congress has not seriously deliberated a fix, though policymakers have floated lifting the income-tax cap, raising the Full Retirement Age, or new taxes on workers and retirees.

One additional option: alter the COLA itself.

What would a flat-rate COLA do?

A 1987 proposal from former Rep. Tim Penny, a Minnesota Democrat who served from 1983 to 1995, would set a flat dollar adjustment using the 20th percentile benefit. Rank all recipients by benefit amount, take the highest benefit in the bottom fifth, and pay everyone that same dollar figure — leaving 80% of beneficiaries with a smaller adjustment, explained Rich Johnson, vice president of financial security at the AARP Public Policy Institute.

The 2026 numbers illustrate the gap. The average beneficiary received a 2.8% raise worth $58 a month in January 2026; under the flat-rate method, that adjustment would have been $34 — equivalent to just 1.7% inflation coverage.

"These cuts would continually take place year after year," AARP's Johnson said. "They accumulate over time." Had the change taken effect in 1998, it would have cost the average beneficiary $78,000 over 28 years. "That is the power," he said. "That is why the COLA matters."

Current retirees would feel less pain than new ones with longer horizons; younger Americans would escape initial impact but lose lifetime benefits.

A flat rate at the 20th percentile enacted in 2027 would close half of the 75-year shortfall, according to the Committee for a Responsible Federal Budget, using calculations from Karen Smith of the Urban Institute. A 30th-percentile version closes two-fifths.

Could the COLA be capped?

Under a capped system, everyone still gets an increase, but higher earners hit a ceiling. CRFB's example: with a $900 cap in 2035, a retiree whose benefits total $50,000 and who would have received a $1,000 COLA gets $900 instead. A cap set at the 75th-percentile COLA — hitting the top quarter of beneficiaries — would close about 10% of the shortfall and save $115 billion over a decade.

"A COLA cap would generate immediate savings and meaningfully reduce Social Security's funding gap," the CRFB wrote.

What about switching the inflation index?

The COLA currently uses CPI-W, the index for urban wage earners, not CPI-E, which tracks spending by adults 62 and older. Supporters of a switch argue CPI-E better matches retiree costs, chiefly healthcare: seniors spend roughly twice as much on healthcare as younger urban workers, Mary Johnson said. CPI-E historically outpaces CPI-W, though in gas-price spike years like 2022 and 2023 the COLA ran higher than CPI-E would have produced. The catch: starting CPI-E in December 2028 would widen the long-range shortfall by 7%.

A chained COLA, which accounts for substitutions — chicken instead of beef — appeared in President Barack Obama's 2014 budget before pushback killed it. A chained CPI starting next year would cut $188 billion of spending between 2027 and 2036 and close about 12% of the shortfall, according to the Cato Institute. "Benefits would generally continue to rise to keep pace with inflation, but more slowly than under the current law," its analysis said.

Blunter options exist: cutting the COLA by 0.5 or 1 percentage point after calculation. The one-point cut beginning December 2027 would eliminate 44% of the 75-year shortfall, the Social Security Administration said.

Why the stakes are high

The first automatic COLA arrived in 1975 to combat the inflation of the 1960s and 1970s. Retirees' dependence has grown since, said Robert Conzo, a certified financial planner and CEO of The Wealth Alliance. "They're using Social Security as their primary source of income," he said. "It was never designed for that." Roughly 14% of recipients 65 and older depend on it for 90% or more of family income, a 2024 Census Bureau Center for Economic Studies report found.

"It is better that we are grateful that we even have one because there are certainly efforts to reduce it or eliminate it altogether for some people," Mary Johnson said. "We want to stick together on this and protect this benefit."

Every proposal on the table trades retiree purchasing power for solvency, and none alone closes the gap — meaning any eventual deal will likely bundle several of these cuts at once.
