Why the CPI Doesn't Fully Capture What Retirees Actually Pay -- and What to Do About It

The article explains that Social Security COLAs are based on the CPI-W, which excludes fully retired households, so it understates cost increases that matter to seniors. The Consumer Price Index for the Elderly (CPI-E) weights medical and other senior-heavy expenses more heavily; an analysis by The Senior Citizens League shows CPI-E would have produced larger COLAs in 8 of the 10 years from 2014–2024. Lawmakers have proposed switching to CPI-E, but changes are unlikely while Social Security faces near-term insolvency because higher COLAs would raise program costs. For beneficiaries, the practical market impact is reduced purchasing power from current COLAs and increased pressure on retirees to tap savings, work longer, or seek other benefits. Policymakers weighing index changes would face fiscal trade-offs that could affect government spending outlooks and the broader debate over entitlement reform.
