IRAs' Unexpectedly Minor Role in Retirement Income: A Closer Look
IRAs: A Supplemental Stream, Not a Primary Pillar
The Discrepancy Between IRA Assets and Retirement Income Contribution
Many financial experts advocate for maximizing contributions to Individual Retirement Accounts (IRAs) as a cornerstone of retirement planning. However, a recent survey paints a different picture of how these accounts actually function for retirees. While IRAs represent the largest share of U.S. retirement assets, they often serve as a supplementary income source rather than a primary one.
Social Security Dominance and Declining IRA Reliance
According to the 2026 EBRI/Greenwald Retirement Confidence Survey, over 90% of retirees depend on Social Security for income. In stark contrast, just over half of retirees (56%) reported drawing from an IRA in 2026, a decrease from 59% the previous year. This trend suggests a diminishing role for IRAs as a primary income stream. Furthermore, a significant gap exists between workers' expectations and retirees' realities: 71% of workers anticipate using IRAs for retirement income, but only 54% of retirees actually do.
The Enduring Power of Social Security
Social Security's prominence can be attributed to its simplicity and consistency. Unlike IRAs, it doesn't demand stringent savings discipline or complex investment decisions. Contributions are managed automatically, and benefits are disbursed regularly, providing a reliable foundation for most retirees' budgets.
Trillions in IRAs: A Supporting Role in the Retirement Pyramid
Despite their less prominent role in daily income, IRAs remain a colossal component of the American retirement system, holding a staggering $19.2 trillion of the total $49.1 trillion in U.S. retirement assets at the end of 2025. This massive wealth, however, is not evenly distributed. Historically, retirement income was viewed as a "three-legged stool" of Social Security, pensions, and personal savings. A more accurate modern metaphor is a five-layer pyramid, with Social Security as the base, followed by homeownership and workplace plans. IRAs occupy a higher tier, with other assets at the very top. This tiered structure suggests that IRAs become more critical for individuals with higher earnings who require more income beyond what Social Security provides, underscoring their concentrated impact rather than widespread dependence.
Retirees' Delayed IRA Withdrawals: A Strategic Choice
The median IRA balance of $150,000, while substantial, yields a modest annual income of approximately $6,000 when adhering to the 4% withdrawal rule. This pales in comparison to the average annual Social Security benefit of around $23,712 in 2025. Data indicates that most IRA owners are not in urgent need of these funds, often delaying withdrawals until mandated by the IRS. Only a small percentage (9.5%) of IRA owners initiate distributions at age 59 (when penalties cease), a figure that gradually rises to 29.6% by age 72. A significant surge to 76.9% occurs at age 73, coinciding with the commencement of required minimum distributions (RMDs) for most retirees. Roth IRA holders, exempt from RMDs during their lifetime, often defer withdrawals even longer. This behavior highlights that for many, IRAs function as a flexible, supplemental income stream, primarily utilized when legally required or strategically beneficial, rather than forming the bedrock of their retirement finance
