Millions of Social Security recipients received a 2.8 percent cost-of-living adjustment for 2026, but a bipartisan group of lawmakers argues that annual raise still shortchanges older Americans whose spending on health care outpaces the general population’s. Senate bill S.3059, the Boosting Benefits and COLAs for Seniors Act, would let the Social Security Administration use whichever price index produces the larger increase each year, choosing between the current Consumer Price Index for Urban Wage Earners (CPI-W) and a new index tracking prices for Americans 62 and older.
Why the current COLA formula falls short for retirees
Under existing law, the annual COLA equals the percentage rise in the CPI-W between the third-quarter average of the current year and the third-quarter average of the last year a COLA took effect, as the Social Security Administration’s benefit adjustment rules explain. That index reflects spending patterns of younger, working households. Retirees, by contrast, devote a larger share of their budgets to medical care, prescription drugs, and housing, categories where prices have consistently risen faster than overall inflation.
The Bureau of Labor Statistics already maintains a research series called the R-CPI-E, which reweights the standard consumer basket to reflect spending by Americans age 62 and older. Relative-importance tables in that experimental index show medical care carries a noticeably higher weight in the elderly-focused basket than in the CPI-W. Over time, that difference compounds into a meaningful gap. A 2012 Congressional Budget Office analysis found that health-care price measurement differences can widen the divergence between elderly and general-population inflation, though the magnitude depends on how quality adjustments and new medical technologies are handled.
The sponsors’ core argument is straightforward: because retirees spend more on categories where prices climb fastest, a formula built around working-age spending systematically understates the erosion of purchasing power for people who depend on Social Security checks. When inflation is driven by hospital services, long-term care, or out-of-pocket prescription costs, a CPI-W-based COLA can leave seniors falling behind even as their nominal benefits tick upward each January.
How S.3059 would rewrite the COLA calculation
The bill, introduced by Senators Richard Blumenthal of Connecticut and Kirsten Gillibrand of New York alongside Representatives Ruben Gallego of Arizona and Nikki Budzinski of Illinois, would revise the statute to give retirees the benefit of the doubt when price measures diverge. According to the sponsors’ legislative summary, S.3059 amends Section 215(i)(1)(D) of the Social Security Act so that each year the SSA compares the percentage increase produced by the CPI-W against the percentage increase produced by a new official CPI-E, then applies whichever number is higher when calculating the COLA.
Because the CPI-E does not yet exist as a formally published monthly index, the bill text includes a transition rule. Until the Bureau of Labor Statistics begins publishing the CPI-E on a monthly basis, the SSA would rely on BLS’s existing R-CPI-E research series as a stand-in for the elderly price index. Once an official CPI-E becomes available, it would replace the research series in the COLA calculation. In either case, the agency would still follow the familiar third-quarter-to-third-quarter comparison, but it would run the calculation twice-once with the CPI-W and once with the elderly index-and adopt the larger percentage as the year’s COLA.
Structurally, this approach creates an asymmetric rule: retirees are protected when elderly inflation runs hotter than general inflation, but they are not penalized when the reverse occurs. If, for example, gas prices spike while medical inflation is subdued, the CPI-W might outpace the CPI-E, and seniors would receive the higher CPI-W-based adjustment. If prescription drug costs surge while energy prices fall, the CPI-E would likely produce the bigger increase, and that figure would govern the COLA instead.
Budget trade-offs and political prospects
Linking benefits to the more generous of two inflation measures would, over time, increase Social Security outlays relative to current law. Higher COLAs compound from year to year, so even modest annual differences can add up to noticeably larger checks for long-lived beneficiaries. Supporters argue that this is a feature, not a bug, contending that current-law COLAs already fall short of what is needed to keep pace with seniors’ real-world costs.
Critics, however, are likely to focus on the program’s long-term finances. Any change that raises scheduled benefits without new revenue would widen Social Security’s actuarial shortfall unless paired with offsetting tax increases or other reforms. Lawmakers backing S.3059 frame the measure as part of a broader effort to strengthen retirement security, but they have not yet coalesced around a single package that simultaneously adjusts COLAs and addresses the trust funds’ projected depletion.
For now, the proposal highlights a growing consensus that a one-size-fits-all inflation index may not be adequate for a population whose budgets are dominated by health care and housing. Whether Congress ultimately enacts S.3059 or pursues a different path, the debate over how to measure the true cost of aging is likely to remain central to future Social Security negotiations.
