Social Security’s 2027 Raise Forecast Slips to 3.5% Ahead of October Announcement

The Senior Citizens League has trimmed its forecast for the 2027 Social Security cost-of-living adjustment (COLA) to 3.5%, down from an earlier estimate of 3.6%, according to The Motley Fool.

The nonprofit advocacy group revised its number after reviewing August inflation data.

The Social Security Administration will not confirm the actual figure until Oct. 14, 2026, when the Bureau of Labor Statistics publishes its September inflation report, The Motley Fool reported.

That data is the last piece needed to calculate the raise, which is tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W, a measure of price changes for working-age households rather than retirees.

Estimates Vary Across Groups

AARP has put its own 2027 COLA projection at 3.6%, slightly above the Senior Citizens League's 3.5% figure. Independent Social Security analyst Mary Johnson also estimates 3.5%.

Either figure would top the 2.8% COLA that took effect in 2026, which itself followed a 2.5% increase in 2025 and a 3.2% increase in 2024.

A COLA in the 3.5% to 3.6% range would mark the largest annual increase since the 8.7% jump in 2023, Motley Fool writer Keith Speights noted.

Tariffs And War Are Pushing Inflation Higher

Motley Fool analyst Sean Williams attributed part of this year's inflation pressure to two Trump administration policies.

Tariffs imposed under the April 2025 "Liberation Day" order, later struck down by the Supreme Court in February 2026, raised consumer prices before that ruling took effect.

The Iran war has also pushed up fuel costs, particularly diesel, alongside the ongoing Russia-Ukraine conflict. Rising gas prices could still shift the September inflation reading before the SSA locks in the final COLA number.

What A Raise Would Mean In Dollars

A 3.5% COLA would turn a $2,000 monthly benefit into $2,070. A 3.6% adjustment would add roughly $75 a month, or about $900 a year, for the average retired worker.

But the net gain looks smaller once Medicare costs are factored in.

Medicare Part B premiums, which are deducted directly from Social Security checks, are projected to rise $6.60 a month to $209.50, while the Part B deductible could climb from $283 to between $292 and $310.

Part D prescription drug plan subsidies are also ending, and the standard Part D deductible could jump 14%, from $615 to $700.

Program's Financing Gap Remains Unresolved

Social Security's trust fund surplus has been shrinking because the program pays out more than it collects. Without a fix, benefits could eventually be cut to roughly 78% of scheduled amounts, turning a $2,000 payment into $1,560 and erasing the value of any COLA.

The Committee for a Responsible Federal Budget has floated a flat-rate COLA structure as one possible remedy. Under that proposal, about 80% of beneficiaries would receive a smaller increase than they would get under the current system.

More than 71 million people, including retired workers, disabled workers and survivors, receive Social Security benefits, with roughly 55 million of them retirees.
