Automatic Enrollment Proves Critical in Reducing Retirement Savings Gaps, New Analysis Finds

New research underscores the powerful role automatic features in retirement plans play in improving financial outcomes for American workers. According to a recent analysis by a prominent retirement policy institute, features like automatic enrollment, contribution escalation, and portability can significantly reduce retirement savings shortfalls—particularly for younger and mid-income workers.

The findings are based on projections from a widely used simulation model that evaluates how policy and plan design changes affect retirement readiness. Originally developed in 2003, the model is frequently used to assess proposed legislation and retirement plan reforms.

The latest analysis reveals that when defined contribution (DC) plans adopt automatic enrollment with a default contribution rate of 6%, the retirement savings shortfall among eligible participants falls by 7%. For workers between the ages of 35 and 39, the reduction grows to over 10%. When automatic contribution escalation is added to the plan, the improvement rises to as much as 9%.

Plans that also include automatic portability—allowing retirement savings to move seamlessly with the participant from one employer to another—see even more substantial improvements. In combination with automatic enrollment and escalation, auto-portability drives the retirement savings shortfall down by 16% across all ages, and by an impressive 26% among those aged 35 to 39. Additionally, participants in this age group are nearly 9 percentage points more likely to avoid running out of money in retirement.

Younger workers stand to benefit the most over the long term. For those with 27 to 30 years of plan eligibility ahead, the savings shortfall could decline by as much as 60%, according to the projections.

The research emphasizes the especially strong impact these features have for workers in small and mid-sized plans, as well as for lower-income participants—groups historically less likely to contribute enough toward retirement.

While automatic enrollment is becoming more common among larger plans, adoption remains limited among smaller employers. Researchers suggest that plan sponsors and policymakers should pay closer attention to the long-term benefits of incorporating automatic features, not just to increase contributions, but to improve asset retention and ensure broader retirement security.

Ultimately, the study reinforces the idea that thoughtful plan design—anchored by automation—can dramatically improve the financial futures of millions of workers.
