Just like a well-built home needs routine inspections to stay safe, efficient, and structurally sound, a company’s 401(k) plan also requires ongoing attention. Even when everything appears to be working smoothly, hidden issues can surface over time, affecting costs, compliance, and employee outcomes. Regular benchmarking helps plan sponsors stay ahead of potential problems, offering clarity, confidence, and long-term stability.

Benchmarking a 401(k) means comparing your plan’s fees, features, investment lineup, and participant outcomes to industry standards. This process acts as an audit of sorts, revealing whether your plan is performing as well as it should. Many plans unintentionally drift into a "set it and forget it" mode—an approach that can lead to outdated fund menus, unnoticed fee creep, or participant disengagement. Studies have shown that a significant percentage of U.S. retirement plans contain fiduciary or compliance issues that could have been caught through consistent benchmarking.

Evaluating Investment Performance and Exploring Better Options

Reviewing investment performance is a core element of benchmarking. Markets evolve, fund management changes, and new, more efficient investment options frequently emerge. Without regular reviews, a plan can fall behind. Consider a scenario where an outdated fund has lagged its benchmark for years—participants may miss out on meaningful growth simply because no one revisited the options. Benchmarking surfaces these gaps and opens the door to better-performing or more cost-effective alternatives.

Keeping Fees Reasonable and Transparent

Unchecked fees can quietly erode participant savings over decades. Benchmarking helps identify whether fees remain competitive and appropriate for the services provided. Even a small reduction can have a major long-term impact. For example, lowering plan fees from 1.5% to 0.1% can add hundreds of thousands of dollars to participants’ retirement balances over time. This type of insight reinforces why periodic evaluation is essential.

Strengthening Fiduciary Compliance and Documentation

Plan sponsors carry a fiduciary responsibility to act in participants’ best interests. Regular benchmarking helps demonstrate compliance with regulatory expectations and provides documentation of thoughtful, prudent oversight. With increasing fiduciary lawsuits and evolving market conditions, many organizations have shifted from reviewing every three years to conducting annual assessments. This proactive rhythm not only supports compliance but also offers peace of mind.

Assessing Participant Engagement and Readiness

A strong 401(k) plan doesn’t just offer solid investments; it supports employees in building retirement readiness. Benchmarking evaluates participation rates, deferrals, and overall engagement to reveal whether the plan is helping employees stay on track. Sometimes minor enhancements—such as adding auto-enrollment, auto-escalation, or Roth options—can significantly boost participation. One organization saw enrollment jump to 98% after implementing auto-enrollment and savings escalation, demonstrating how targeted improvements can truly move the needle.

Identifying Hidden Risks and Preventing Plan Decay

When a 401(k) isn’t reviewed regularly, issues can compound quietly. Outdated funds may underperform for years, fee structures can become misaligned, and participant outcomes may suffer. Benchmarking uncovers these risks early, helping plan sponsors address them before they compromise the plan’s health or expose the company to avoidable legal risk.

Supporting Talent Retention and Productivity

A well-managed retirement plan is a valuable tool for attracting and retaining talent. Conversely, poorly performing plans can lead to delayed retirements, which may increase employer costs. Studies show that each employee who postpones retirement due to inadequate savings can cost an organization tens of thousands of dollars annually through higher healthcare expenses and reduced productivity. Benchmarking keeps your plan competitive and aligned with employee needs.

Staying Ahead Through Proactive Plan Management

Annual benchmarking aligns with broader trends in benefits management and ensures that full RFP processes are only used when necessary. This saves time and resources while maintaining clarity about when meaningful changes truly need to be made.

Regular 401(k) benchmarking empowers companies to stay ahead of problems rather than react to them. By consistently reviewing performance, fees, fiduciary processes, and participant outcomes, plan sponsors protect their companies and support stronger financial futures for their teams. For businesses that want to ensure their plans remain competitive and compliant, seeking expert guidance can make the process more efficient and more impactful.
