Is the 2027 COLA be a flat rate? what to know about the proposed bill that gives retirees the same increase every year

A major change to Social Security ’s annual cost-of-living adjustment is drawing attention just weeks before the 2027 increase is finalized, but retirees shouldn't mistake the proposal for a change that has already become law.

The idea would replace the current percentage-based COLA with a flat-dollar increase. Instead of every beneficiary receiving the same percentage adjustment, everyone would receive the same dollar amount, calculated from the benefit paid to someone around the 20th percentile of the benefit distribution.

Despite references to a “bill” circulating around the proposal, the flat-rate COLA currently attracting attention is a policy proposal, not an enacted change to the 2027 Social Security adjustment.

Under current law, the 2027 COLA will continue to be based on inflation unless Congress changes the system.

How would a flat-rate Social Security COLA work?

Social Security currently applies one COLA percentage to every beneficiary’s payment. A 3% COLA , for example, gives someone receiving $1,200 a month a $36 increase, while someone collecting $2,500 receives $75.

The flat-rate approach would instead calculate one dollar increase using a lower benefit level and give that amount to everyone. AARP estimates that if such a system had been used for the 2026 COLA , the average retired worker would have received about $34.20 more per month instead of the actual $57.90 increase generated by the 2.8% COLA.

The organization estimates roughly 80% of beneficiaries would receive smaller annual adjustments under the proposed structure. The Committee for a Responsible Federal Budget argues the approach could improve Social Security ’s finances while concentrating more benefit growth toward lower-income recipients.

Its modeling found a flat-rate COLA set at the 20th percentile could close roughly half of the program’s projected 75-year funding shortfall under the assumptions it examined.

AARP strongly disagrees with the approach, arguing that smaller increases would compound over time and gradually reduce purchasing power for most beneficiaries.

What does this mean for the 2027 COLA?

Nothing has changed yet. AARP’s latest projection, updated Sept. 11, estimates a 3.6% COLA for 2027. That would add roughly $75 a month to the average retired worker’s benefit, although the final figure will depend on September inflation data.

The Social Security Administration calculates COLA using third-quarter CPI-W inflation data, with the official adjustment finalized after September figures become available.

Retirees therefore should not expect a universal flat-dollar increase in January 2027 based on the proposal currently being discussed.

The broader debate is still significant because Social Security faces a substantial long-term financing shortfall, and policymakers are considering numerous approaches to address it.

The flat-rate COLA is one option in that debate, not the formula currently scheduled to determine next year’s checks.
