Fixing the usability gap in employee benefits

What is the benefits usability gap? It’s the distance between the benefits employers offer and the ones employees actually use. Only about a quarter of employees participate in wellbeing programs, while more than half turn to consumer health apps instead. The gap isn’t cause by a lack of awareness, but instead it’s a fragmented, hard-to-navigate experience.

For more than a decade, employers have been expanding access to health and wellbeing benefits. More programs, more platforms, more point solutions for everything from digital mental health to specific medical conditions. Yet it’s becoming harder to ignore reality: Even though most employees have access to a wide range of benefits, they’re not taking full advantage of them.

This isn’t a benefits problem. It’s a product problem.

Why aren’t employees using their benefits?

A growing body of research, including our own, shows that employees aren’t opting out of care. They’re simply opting out of employer benefits. According to Gallup, only about one-quarter of employees actively participate in wellbeing programs, highlighting a persistent gap between what is offered and what is actually used. More than half of employees now use consumer health or wellness apps, and nearly half pay out of pocket for tools their employer may already cover, according to Castlight’s recent research. In fact, many spend $250 to $500 or more each year to assemble their own “DIY health ecosystem” outside of employer offerings.

They’re not doing this because they’re ungrateful. They’re doing it because the consumer experience is often better: simpler, more intuitive, more personalized and available at the exact moment they need it.

When employees route around your offerings to solve the same problem, you don’t have an awareness issue. You have a usability and relevance issue.

How does benefits fragmentation hurt engagement?

In theory, employer-sponsored benefits should outperform consumer tools. They remove cost barriers, connect employees to broader care pathways and reinforce engagement over time. More than half of employees even say they would trust a digital health solution more if it is offered by their employer, according to Mercer.

But in practice, the experience breaks down.

The problem? Employees aren’t navigating a single system. They’re navigating a patchwork of portals: one app for mental health, another for pharmacy, another for navigation, another for care management. Mercer’s research shows that this fragmentation quickly leads to confusion and disengagement.

So when a new need arises, employees don’t start with their benefits. Our research shows that more than one-third immediately seek their own solution, even if they have to pay out of pocket, because it feels faster and clearer than figuring out where to begin with their benefits.

Engagement isn’t low; it’s just happening outside of employer offerings.

What does low benefits engagement cost employers?

Across $13.1 billion in customer claims data, one pattern is consistent: 20% of individuals drive 82% of total health care costs.

But the more insidious risk lies with the “apparently healthy.” These are the employees who look well on paper but carry hidden risks that could easily be managed, but often turn into catastrophic claims because they opt out of regular care. The difference between a $2,000 preventive screening today and a six‑figure diagnosis tomorrow is simply engagement.

The cost of disengagement isn’t just clinical. More than 80% of employees told us that they’re more likely to stay with an employer that offers flexible wellness benefits. When benefits feel irrelevant, it’s not just a matter of low utilization; it’s quietly eroding employee loyalty, too.

7 ways employers can close the benefits usability gap

Closing the gap between access and utilization doesn’t require adding more solutions. It requires building an experience employees actually want to use.

Here are some proven ways employers can do just that:

• Create a clear front door. Employees should not have to navigate multiple entry points. A unified navigation layer is the most impactful change an employer can make to improve usage and engagement.
• Simplify the ecosystem. Many organizations have added solutions over time without removing outdated or duplicative ones. Reducing overlap and clarifying each tool’s role can significantly improve usability.
• Design for moments, not enrollment cycles. Many employees first engage with benefits when an unexpected need arises. Align benefits with real-life triggers – life events, diagnoses and urgent moments – rather than relying on open enrollment.
• Embrace segmentation. Younger employees want benefits that integrate with tools they already use. Those 55+ prioritize chronic condition support. A single architecture cannot meaningfully serve both. 
• Let employees bring their own tools. Many employees prefer that benefits apply to products they already use. This is a clear mandate for flexible models – stipends, curated marketplaces and reimbursement frameworks – over locked-down point solutions.
• Integrate guidance. The most effective models combine digital tools with human support, helping employees understand what to use and when, then reinforcing engagement over time.
• Measure what matters. Downloads and registrations do not equal success. Activation, repeat use and outcomes are the metrics that reflect real value.

What do employees expect from their benefits experience?

Employees wake up every morning using products that anticipate their preferences and let them get anything done in three taps. Then they open their benefits portal and face an overwhelming patchwork of programs, vendors and tools they’re somehow expected to decipher and stitch together on their own. That contrast is one of the biggest reasons engagement keeps slipping, and why fixing it remains such a challenge.

Employers that will win on workforce health are the ones that stop measuring success by the number of benefits programs they offer and start measuring by what actually gets used, and by whom.

Access to benefits is just the starting point. Utilization is where true value is created.
