401(k) Plan Resource Center

The 401(k) plan retirement system now holds $3.0 trillion in assets on behalf of 50 million active participants and millions of former employees and retirees. Despite the increased popularity of these plans, more must be done to help working Americans take the fullest possible advantage of the opportunity to save for retirement through their 401(k) plans. Research shows that Americans will save more through defined contribution plans with proper incentives, services, and guidance. Better understanding of 401(k)s, through education and disclosure, will also boost participation.

Policymakers should also take steps to ensure that the number of workers covered by 401(k) plans continues to expand. That means encouraging more employers, small and large, to open 401(k) plans by making them as simple and accessible as possible.

This resource center provides the fund industry's perspective on developments that affect 401(k) plans and their investors. It includes ICI's research and analysis of the 401(k) plan market and participant activity, as well as our advocacy for cost-effective 401(k) planning tools, services, and disclosure.
