What 2024 Social Security COLA Could Look Like Under Alternative Calculation Methods

Over 71 million Americans depend on Social Security benefits each month, making the annual cost-of-living adjustment (COLA) a critical factor in determining their financial stability. As inflation data from September gets processed, the Social Security Administration prepares to announce 2024’s COLA figure — a number that will directly impact monthly payments for retirees nationwide.

Current COLA Projections vs. Historical Context

Preliminary estimates suggest 2024’s COLA will land between 3% and 3.2%, marking a significant drop from 2023’s unprecedented 8.7% increase. To put this in perspective, if COLA reaches 3%, the average monthly benefit for retired workers would climb approximately $55, bringing payments to roughly $1,892 from the current $1,837.

The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) serves as the traditional benchmark for calculating these adjustments. However, a growing debate centers on whether this methodology truly captures the financial realities facing older Americans.

The Case for Alternative Measurement: CPI-E Explained

Two legislative proposals — the Fair COLA for Seniors Act and the Social Security Expansion Act — suggest a fundamental shift in how adjustments should be calculated. Rather than relying on CPI-W data, these bills advocate switching to the Consumer Price Index for Americans aged 62 and older (CPI-E).

The rationale appears straightforward: CPI-E tracks price changes on items elderly Americans actually purchase, with particular emphasis on healthcare and prescription medications. Supporters argue this approach would better reflect real spending patterns and preserve purchasing power where it matters most.

Representative John Garamendi, a sponsor of the Fair COLA initiative, emphasizes that “using an adjustment mechanism reflecting actual retiree expenditure patterns — especially medical expenses — represents a practical improvement that strengthens benefits and better serves the program’s intended recipients.”

The Economist’s Counterargument: Technical Limitations

Despite its intuitive appeal, economists raise substantial concerns about CPI-E reliability. According to Marck Goldwein of the Committee for a Responsible Federal Budget, this alternative index suffers from methodological weaknesses that undermine its credibility.

CPI-E relies on a smaller sample size than CPI-W, resulting in less robust data collection. It fails to account for annual shifts in consumer spending behavior and overlooks critical factors like substitution bias — the tendency for consumers to switch toward more affordable alternatives as prices rise. The index also doesn’t adequately measure true housing costs or the discounts seniors frequently utilize.

Goldwein’s analysis reveals a troubling pattern: over the past two years, CPI-E has consistently grown slower than broader inflation measures. This trend suggests that advocates would likely oppose this method if it consistently produced lower adjustments rather than higher ones.

Practical Impact and Long-Term Implications

Under CPI-E methodology, last year’s COLA would have measured 8% rather than 8.7%. While this differential might seem modest, the cumulative effect matters for benefit calculations. However, projections indicate that even modest improvements from switching indices pale against the looming Social Security solvency crisis.

Adopting CPI-E might produce marginal gains of approximately 0.2% annually, but this benefit could be offset by accelerated strain on the Old-Age and Survivors Insurance and Disability Insurance Trust Funds. The structural challenges facing Social Security extend far beyond measurement methodology.

What This Means for 2024 and Beyond

As the Social Security Administration finalizes 2024’s COLA announcement, millions of beneficiaries will see their monthly payments adjusted according to the established CPI-W formula. Meanwhile, the debate over alternative calculation methods continues in legislative chambers, highlighting ongoing disagreements about balancing immediate relief against long-term program sustainability.

For seniors navigating rising healthcare costs and inflation, the difference between a 3% and a theoretically higher COLA represents more than academic debate — it directly affects their ability to meet essential expenses throughout retirement.
