Do Supplemental Benefits Actually Reduce Employee Turnover?

When an employee gets diagnosed with cancer or has a heart attack, the medical bills are only half the problem. The other half? They can’t work — and their paycheck stops, but their mortgage doesn’t.

That’s the gap most employer health plans don’t cover. And it’s exactly where voluntary supplemental benefits step in.

What Are Supplemental Payouts — and Why Do Employers Care?

Supplemental insurance plans — critical illness, accident, and disability income — pay employees a lump-sum cash benefit directly when a covered event happens. Unlike medical insurance, which pays the hospital, this money goes to the employee. They use it however they need to: rent, car payments, childcare, travel for treatment — whatever keeps their life running while they recover.

The numbers tell the story:

• 31% of American workers filed a critical illness insurance claim in the past 12 months, according to Equitable’s 2025 Consumer Finance Survey. That’s nearly one in three employees.
• 78% of U.S. employees now have at least one chronic health condition, a 7% increase since 2021, according to the Integrated Benefits Institute.
• 80% of Americans worry that an unexpected medical expense could derail their financial goals — and more than a quarter say a bill under $1,000 would cause real hardship.

For employers, those aren’t just health statistics. They’re retention risks. When a key employee faces a serious diagnosis without financial protection, they’re more likely to leave — or worse, stay but disengage while they scramble to cover costs.

The Real Cost of Losing an Employee

Here’s what the data says about turnover in 2026:

• The overall U.S. voluntary turnover rate is 23.4% annually, according to BLS JOLTS data.
• Replacing a single employee costs one-half to two times their annual salary, per Gallup research.
• SHRM benchmarks the average cost per hire at roughly $4,700 — and that’s just the recruiting side, not the lost productivity during the 44-day median time-to-fill.

For a 100-person company with 23% turnover, that’s 23 departures a year. At a $60,000 average salary, the replacement cost alone could exceed $400,000 annually — before you account for the institutional knowledge walking out the door.

Now consider this: what if a critical illness payout kept even a few of those employees from leaving?

How the Payouts Actually Work

Supplemental benefits are typically offered as voluntary plans — employees elect them and pay premiums through payroll deduction. Here’s what real-world payouts look like:

Critical Illness Insurance

• Lump-sum benefit: $2,500 to $50,000 depending on the diagnosis and coverage level
• Covers: cancer, heart attack, stroke, organ transplant, kidney failure, and other serious conditions
• The employee decides how to use the money — no restrictions

Accident Insurance

• Payouts for specific injuries and medical services: $25 to $15,000 per injury (MetLife example)
• Hospital admission benefits: $1,000 to $1,500 per admission, plus daily confinement payments
• Emergency room visits, ambulance transport, physical therapy — all covered separately

Disability Income Insurance

• Monthly benefit: typically 50–70% of the employee’s salary if they can’t work due to illness or injury
• Covers the gap between when sick leave runs out and when the employee can return

In one real-world scenario, an employer reported that supplemental plans paid out $10,000 in critical illness benefits, $2,650 in accident benefits, and $12,600 in disability income — helping that employee avoid financial ruin during a serious health event. Across the workforce, the employer estimated the plans saved over $100,000 per year in reduced turnover and absenteeism costs.

The Tax Advantage Most Employers Miss

Here’s where it gets interesting from a cost perspective. When supplemental benefits are offered through a Section 125 Cafeteria Plan, both the employer and employee save on taxes:

• Employees pay premiums with pre-tax dollars — reducing their taxable income
• Employers save on FICA, FUTA, and state unemployment taxes because the premiums are deducted before payroll taxes are calculated
• The benefits themselves are generally tax-free to the employee when paid out

That means the employee gets more coverage for less take-home pay reduction, and the employer gets a more competitive benefits package at a lower effective cost. It’s one of the few benefits that genuinely works for both sides of the equation.

Why This Matters for Retention

The connection between supplemental benefits and retention isn’t theoretical. When employees know they have a financial safety net, they’re more likely to stay. Here’s why:

1. Financial stress is the top driver of disengagement. An employee worrying about how to pay for cancer treatment isn’t focused on their work. Supplemental payouts remove that pressure.

2. Benefits signal that the employer invests in their people. Offering critical illness, accident, and disability coverage says: “We thought about what happens when life gets hard — and we built a plan.” That message sticks.

3. Voluntary benefits are low-cost to the employer, high-value to the employee. Because employees typically pay the premiums (pre-tax through Section 125), the employer’s direct cost is minimal — mostly administration and plan setup. But the perceived value to employees is significant.

4. They close the gap that medical insurance leaves open. High-deductible health plans are increasingly common. Supplemental benefits cover the out-of-pocket and living expenses that medical plans don’t touch.

What Employers Should Ask

If you’re reviewing your benefits package and wondering whether supplemental plans make sense, here are the questions worth asking:

• What percentage of our workforce has chronic health conditions? The national average is 78%. Your number may be higher or lower, but it’s almost certainly significant.
• What happens to an employee’s income if they’re diagnosed with a serious illness? If the answer is “they rely on sick leave and then short-term disability,” there’s a gap.
• Are we offering supplemental benefits through a Section 125 plan? If not, both the employer and employees are leaving tax savings on the table.
• How are we communicating these benefits? Even the best plans fail if employees don’t understand them. According to Equitable’s survey, less than half of workers had low confidence in their understanding of critical illness insurance — but once they learned what it covered, 89% found it very helpful.

The Bottom Line

Supplemental benefits aren’t a luxury perk for Fortune 500 companies. They’re a practical, tax-advantaged tool that helps employers protect their workforce — and their bottom line — when the unexpected happens.

The real question isn’t whether you can afford to offer them. It’s whether you can afford not to.
