Most employers track premium spend down to the dollar. Very few track what happens when employees don’t use the benefits that premium is paying for. The downstream cost of low utilization is almost always larger than the premium itself, and almost no one measures it.
When benefits function as a line item on a spreadsheet rather than a tool your workforce actually reaches for, the savings you think you’re getting from a low-utilization plan don’t exist. The costs just move. They land in absenteeism, presenteeism, turnover, and next year’s claim history. The premium stays visible. The downstream cost stays hidden.
This article is about what’s in that hidden column, and how to read your own business to see it.
Absenteeism: The Easy Number to Find
Absenteeism is the most visible cost of a plan employees can’t use, because the worker who can’t afford a doctor’s visit eventually takes a sick day instead. Or two. Or eight.
The Integrated Benefits Institute estimates that poor health costs US employers $575 billion annually and accounts for 1.5 billion lost workdays per year across all forms of illness-related absence. The CDC found that workers with chronic diseases miss substantially more workdays than their healthier counterparts, with the cost compounded by team dependencies. When a coworker has to cover, the effective productivity loss multiplier ranges from 1.5 to 2 times the direct wage.
Put more simply, a day of absence doesn’t cost you the absent worker’s day of wages. It costs you that plus the drag on everyone who had to cover the gap.
Presenteeism: The Expensive Number Almost No One Tracks
Presenteeism is when an employee is physically at work but isn’t getting the work done, usually because untreated or under-treated health issues are interfering. It’s harder to see than absenteeism because the timecard looks fine. The output tells a different story.
Harvard Business Review, citing an American Productivity Audit, estimated that presenteeism costs US employers over $150 billion per year, more than absenteeism. Peer-reviewed research published in PubMed analyzing ten common health conditions found that presenteeism costs exceeded medical costs for most of them, representing 18% to 60% of the total cost of each condition.
One analysis estimated the ratio as roughly 10 to 1. For every dollar lost to absenteeism, presenteeism could cost employers up to ten.
What drives presenteeism? Untreated or under-treated chronic conditions. Mental health strain. Delayed care. Precisely the things that happen when employees can’t afford to use the plan you’re paying for.
The employee who can’t afford their deductible doesn’t stop needing healthcare. They just show up sicker, stay sicker longer, and do worse work while they’re sick.
Turnover: The Cost That Hits Twice
Turnover is where bad benefits become unambiguously expensive, because employees who don’t feel their benefits are working for them leave. And replacing them isn’t cheap.
SHRM estimates that replacing an employee costs between 50% and 200% of their annual salary. For hourly workers specifically, SHRM’s historical estimate is around $1,500 per employee, but industry-specific research puts the number higher. A Cornell Center for Hospitality Research study on employee turnover in the lodging and food service sectors puts the average cost of turnover at $5,864 per employee. A 2025 survey of 511 US restaurant operators conducted by 7shifts, a restaurant workforce management platform, found average replacement costs of $1,056 for front-of-house staff, $1,491 for back-of-house, and $2,611 for managers.
The industry context matters more than the specific number. Restaurant turnover in 2025 averaged over 75%. In fast food, turnover can exceed 130%. For an operator with 50 hourly employees and a $2,300 per-head replacement cost, even a 60% turnover rate implies $69,000 per year in direct replacement costs alone. That’s before productivity ramp, customer impact, or team morale.
Now add the benefits connection. The 2025 Selerix Benefits Survey found that employees satisfied with their benefits are five times more likely to say they plan to stay. The Imagine360/Pollfish survey found that 28% of respondents said they would accept a pay cut at a different employer for better health benefits. If your plan is contributing to the voluntary exits, the benefits cost and the turnover cost are the same cost, measured at different moments.
Claim Severity: The Next-Year Cost
Deferred care doesn’t stay deferred. Eventually, the employee shows up at the ER or gets admitted, and the claim that would have cost $200 in a primary care visit costs $8,000 in an inpatient setting.
In the 2025 Pollfish survey of adults with employer-sponsored coverage, 42% of those who delayed care due to cost said their medical condition worsened as a result. This is the renewal-cycle feedback loop most employers don’t see clearly. Last year’s deferred care becomes this year’s claim, which drives next year’s rate increase, which drives more deferral next year.
Plans with high deductibles and low utilization don’t produce predictable, stable claims. They produce volatile, high-severity claim histories that push renewal rates up year after year.
Why Most Employers Never Connect These Dots
The hidden column stays hidden because the metrics live in different places. HR tracks turnover. Operations tracks absenteeism. The broker tracks premiums and claims. Nobody owns the full stack of what low utilization actually costs the business.
When renewal season arrives, the conversation almost always centers on premium and claim experience, because those are the numbers the broker has. The turnover cost, the presenteeism drag, the absenteeism multiplier, and the downstream claim severity from deferred care rarely enter the discussion. So the plan gets shopped on price, and the plan’s structural contribution to the downstream costs never gets examined.
This is why plan design keeps losing. The costs that favor better design are in a column no one is reading.
You can save $40,000 on premiums and lose $150,000 on turnover and absenteeism, and the quarterly report will show the $40,000 win.
Back-of-Envelope Math for Your Own Business
You don’t need a consultant to get a rough sense of what low utilization is costing. Start with the data you already have.
- →Annual turnover count × per-head replacement cost for your industry gives you your baseline turnover spend.
- →Annual absenteeism days × average daily wage × 1.6 to 2x multiplier gives you an absenteeism cost estimate that accounts for coverage drag.
- →Presenteeism estimate: research suggests presenteeism costs are roughly 10x absenteeism. Even at a conservative 3-5x, the number is large.
- →Your current plan enrollment rate. If 50% of eligible employees enrolled last year, the premiums you spent on offered-but-not-enrolled benefits still carry administrative cost, and the employees outside the plan are still driving absenteeism, presenteeism, and turnover risk.
Add those four numbers. Compare to your annual premium spend. If the hidden costs exceed the premium by a factor of 2 or more, which they often do in hourly-workforce industries, the real return on better plan design isn’t incremental. It’s substantial.
The Design That Reduces Hidden Costs
Plans that employees can actually afford to use reduce the hidden costs. No-deductible plans, fixed-copay structures, and limited-day plans designed for hourly operations flip the economics. The employee sees a doctor when they need to. The chronic condition gets managed rather than progressed. The sick day becomes a scheduled appointment instead of an emergency. The employee stays, because the benefits are real.
None of this is magic. It’s what happens when benefits are priced for the people using them. The premium may be similar or slightly different. The hidden costs behave differently.
The employers who win this math aren’t the ones who got the cheapest premium. They’re the ones who looked at the whole column.
