Morningstar’s latest Retirement Plan Landscape report finds that while the average cost of workplace retirement plans continues to decline, expenses still vary significantly—especially for those in smaller plans, who often pay nearly three times as much as participants in large plans. 

These cost discrepancies stem largely from economies of scale, with larger employers able to spread administrative expenses more efficiently. Despite the variation in fees, most participants across plans have access to high-quality investments, with over 94% of defined-contribution assets allocated to Morningstar Medalist-rated options. 

The report highlights that even small plans can be cost-effective, with 20% of them coming in below the median cost for medium-sized plans. However, more than $600 billion has exited workplace retirement plans annually since 2020, often due to rollovers into IRAs when employees change jobs. 

Finsum: Investors should carefully weigh whether their workplace plan offers better value through low fees and strong investment options before making such moves.
