Billions in Forgotten 401(k)s Drain Value in Low-Yield Automatic IRAs

Key points

• PensionBee’s Oct. 21 white paper, using Employee Benefit Research Institute data, shows 68% of automatic rollover IRAs decline in value within one year.
• After eight years, 39% of these accounts are still worth less than when they were created, primarily due to low interest rates and administrative fees.
• Automatic rollovers are projected to double from 1.1 million in 2022 to 2.2 million annually by 2030, potentially trapping $43 billion in 13 million accounts.
• Safe Harbor IRAs, established in 2001 for balances under $7,000, are meant to be temporary but half remain open after eight years, often forgotten by workers.
• Administrative fees, such as $100 opening charges and $5 monthly maintenance, disproportionately harm small accounts, making it difficult for returns to outpace costs.
• More than $2 trillion sits in forgotten or left-behind retirement accounts, with younger workers under 45 most likely to lose track of funds during job changes or moves.

Background

This issue builds on ongoing concerns about retirement savings accessibility, particularly as automated enrollment and tax-advantaged accounts expand. While earlier reports focused on broader financial trends, this story highlights a specific structural flaw in how small 401(k) balances are managed after employment ends. The problem is exacerbated by the rise of gig work and frequent job changes, which increase the likelihood of accounts being left behind. Unlike previous debates on market volatility or investment strategies, this report focuses on the passive erosion of value in accounts that workers may not even know exist.

Why it matters

The erosion of retirement savings in automatic rollover IRAs undermines the core promise of 401(k) plans: long-term growth through compounding. For millions of Americans, especially younger workers, these accounts represent a significant portion of their retirement nest eggs. If left unattended, the combination of low yields and fees can turn potential wealth into a net loss, potentially forcing individuals to rely on Social Security or other safety nets. This issue also raises questions about the effectiveness of current regulatory frameworks, such as Safe Harbor IRAs, which were designed to protect workers but may inadvertently trap funds in suboptimal investments. Addressing this could require policy changes, better employer communication, or more accessible tools for workers to track and manage their retirement assets.

What to watch

As automatic rollovers are projected to double by 2030, the scale of this problem is likely to grow. Policymakers may need to revisit the $7,000 threshold for Safe Harbor IRAs or mandate more active investment options for these accounts. Employers and financial institutions could also play a role by improving notifications and making it easier for workers to locate and consolidate their accounts. Additionally, the Department of Labor’s Retirement Savings Lost and Found Database may expand its reach, helping more Americans reclaim forgotten funds. For individuals, the immediate step is to check resources like the National Registry of Unclaimed Retirement Benefits to ensure no assets are left behind.
