Social Security is a popular but expensive program. With the trust fund facing depletion in just a few years, experts have suggested different ways to cut costs and make the program more sustainable, including raising the full-retirement age or eliminating the payroll tax cap for high-income earners.

Now, the Committee for a Responsible Federal Budget (CRFB), a bipartisan nonprofit, is adding another innovative solution to the mix: limiting cost-of-living adjustments (COLA) for the highest-income earners (1).

In a white paper published in October that cites calculations by the Urban Institute, the organization says the proposed change “could be a rapid, thoughtful, and progressive way to help restore solvency and put Social Security on a sustainable path.”

But, if implemented, this shift could make it difficult for some beneficiaries to sustain their purchasing power later in retirement.

Here’s a closer look at why this change is being proposed and how it could impact your retirement plans.

COLA is a mechanism built into the Social Security system that helps protect beneficiaries from the impact of inflation.

Initially, these adjustments were done on an ad-hoc basis and needed congressional approval. But when inflation flared up in the 1970s, Congress enacted a provision to allow for automatic annual COLAs. Since then, the annual COLA is linked to the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), an official measure of the monthly price change in a basket of goods and services, such as food, energy and medical care.

For 2026, the Social Security Administration pegged COLA at 2.8%. This adjustment will benefit all 75 million beneficiaries of the program.

Under the CRFB’s new proposal, all beneficiaries will still benefit from an annual COLA. However, retirees with the largest benefits — and typically the highest lifetime earnings — will face a fixed dollar amount cap on their annual COLA.

So if COLA is 2% in a given year, someone who receives $50,000 in total annual benefits would typically see a $1,000 bump, but would now face a potential cap at $900 instead. Beneficiaries earning less than $45,000 would still see the full adjustment.
