How Often Should Employers Benchmark Their 401(k) Plan?
Updated August 20, 2026

Plan benchmarking is an ongoing process that compares fees, investments, providers, and participant support as the plan changes.
Key takeaways
Benchmarking is part of ongoing monitoring
A sponsor's work does not end when a provider or investment menu is selected. The Department of Labor describes selecting and monitoring providers and plan investments as ongoing responsibilities. A periodic benchmark helps show that the sponsor is paying attention to cost, service, and participant needs.
Use both a regular cadence and event triggers
Many sponsors include a formal review in their recurring plan governance calendar. An additional benchmark may be appropriate when plan assets or participant count change significantly, service problems continue, fees change, investments are added or removed, the company completes a transaction, or a provider contract approaches renewal.
Compare more than fees
A complete review considers investment options and expenses, recordkeeping, administration, custody, participant education, technology, cybersecurity, reporting, payroll workflow, and sponsor support. The goal is to compare reasonable alternatives using the needs of the specific plan.
Document the conclusion
Keep the materials reviewed, questions asked, alternatives considered, meeting notes, and the reason for the decision. A benchmark may support staying with the current arrangement, negotiating improvements, or exploring a provider transition.
Questions business owners ask
Does every benchmark require formal bids?
Not necessarily. The appropriate process depends on the circumstances. Formal proposals can be useful when the sponsor needs comparable market information or is seriously evaluating a change.
Can Qmulate review only the investment menu?
The scope can be tailored, but a broader review often provides better context because investments, provider compensation, services, and participant outcomes can be connected.
