A flat-rate Social Security cost-of-living adjustment proposal would reduce annual benefit increases for 80% of retirees, according to analysis from the Committee for a Responsible Federal Budget and AARP released in late July and August 2026. Under the proposal, all beneficiaries would receive the same fixed dollar increase each year, rather than a percentage increase tied to inflation as the current system provides.
The flat-rate COLA would set annual adjustments by multiplying the inflation rate by the benefit amount received by someone at the 20th percentile of the benefit distribution. For 2026, that would have meant a monthly increase of $34.20—based on 2.8% inflation applied to a $1,223 monthly benefit—rather than the $57.90 average retirees actually received under the current percentage-based system.
The proposal would hit older beneficiaries hardest as its impact compounds over time. AARP’s analysis found that a retiree who began collecting an average benefit in 1998 would have seen their annual payment reach $22,600 by age 93 under the current inflation-protected system. Under a flat-rate COLA in effect since 1998, that same person’s 2026 annual benefit would amount to only $18,000—a shortfall of $4,600, or 20%. Over their full retirement, cumulative losses would exceed $77,900 in inflation-adjusted dollars, according to AARP’s Public Policy Institute.
The flat-rate COLA would be highly progressive in its benefit distribution, according to CRFB analysis. If set at the 20th percentile, the bottom fifth of lifetime earners would see their benefits fall by just 3% by 2065, while the top fifth would face a 19% reduction. At a higher percentile threshold, the bottom quintile could actually receive a 1% benefit increase while the highest earners would see 17% cuts.
Despite cutting benefits for most retirees, the proposal would address Social Security’s long-term solvency challenge. The CRFB found that a flat-rate COLA enacted in 2027 would close about 50% of Social Security’s 75-year funding shortfall. The Social Security trust fund is projected to run dry by late 2032, at which point incoming payroll taxes would cover only about 78% of scheduled benefits without legislative action.
The flat-rate COLA concept is not new. Former Representative Tim Penny, a Democrat from Minnesota, first proposed a similar idea in 1987. The Committee for a Responsible Federal Budget, which Penny now co-chairs, recently elevated the proposal as part of its Trust Fund Solutions Initiative. The Washington Post editorial board endorsed the proposal in July 2026, citing its potential to address the program’s fiscal challenges.
AARP argues the proposal would intensify financial hardship for vulnerable populations. The organization noted that 20% of adults ages 65 and older rely on Social Security for at least 90% of their income, and nearly 60% of those 75 and older have no retirement savings. Under a flat-rate COLA, a woman retiring at 65 in 1998 with an average female retiree benefit would fall below the poverty line by age 93, according to AARP’s calculations. A man receiving a disabled worker benefit from a 1998 injury would similarly drop below the poverty threshold by age 64 under the proposal.
The proposal would need to be paired with other reforms to achieve full solvency. CRFB estimates that a flat-rate COLA alone would only delay Social Security’s insolvency by two years. Combined with other policy changes such as an expanded payroll tax base, however, it could permanently restore the program to balance, the analysis found.
