How Employers with 20 to 100 Employees Assess Their Own Health Plan Risk Before Choosing a Funding Strategy

Most mid-size employers make their health plan funding decision once a year, when the renewal arrives with a new rate. Very few do the internal work beforehand to understand their own group's risk profile. The result: the conversation gets defined by whoever put together the renewal presentation, and the employer's role is mostly reactive.

Before choosing between a fully insured plan, a level-funded arrangement, a self-funded design, or a multiemployer trust, you need to understand four things about your own group: how volatile your monthly claims have been, how much financial exposure your business can absorb in a difficult year, whether your current plan structure creates compliance gaps you have not addressed, and whether your workforce's actual utilization patterns match the plan you are paying for.

Health plan risk assessment is the process of answering those four questions using data you already have access to. What follows is the framework that benefits advisors run through in a discovery session before recommending any funding arrangement. Working through it before your next renewal puts you in a measurably stronger position at that table, regardless of which option you ultimately choose.

The Four Questions That Belong at the Start of Every Health Plan Funding Decision

Question 1: How Volatile Have Your Monthly Claims Been Over the Last 24 Months?

In a fully insured plan, claims volatility rarely comes up, because your premium is fixed regardless of what your group actually spends on medical care each month. But the moment you consider any alternative funding arrangement, monthly claims volatility becomes the primary variable in the conversation.

Claims volatility measures how much your group's monthly medical spending swings above and below its own average. A group with a $50,000 monthly average that ranges from $28,000 to $84,000 in any given month has high volatility. A group whose claims consistently run between $44,000 and $57,000 has low volatility. The difference determines how predictable an alternative funding structure would be, month to month, on your actual budget.

For evaluating a level-funded plan, a useful starting threshold is a monthly swing of plus or minus 5% around your average. Groups whose claims stay within that range are strong candidates for level-funded designs because the plan's fixed monthly structure corresponds closely to how their actual spending behaves. Groups with wider swings need to look carefully at stop-loss attachment points before committing to any variable-cost structure.

According to the Kaiser Family Foundation's 2024 Employer Health Benefits Survey, employer health plan costs rose an average of 7% in 2024, but individual group experience varies enormously. Groups with stable, predictable claims often pay premiums inflated by pool-wide trend that does not reflect their own experience at all. Identifying your group's actual volatility is the first step to knowing whether you are in that situation.

Question 2: How Much Financial Exposure Can Your Business Absorb in a High-Claims Year?

This question does not have a universal answer, but it has a right answer for your specific business. An employer with six months of operating cash reserves and predictable seasonal revenue can absorb more stop-loss exposure than one running on tight margins with a one-month cash cushion. The honest answer to this question should drive your stop-loss design if you move to an alternative funding arrangement.

In a self-funded or level-funded plan, stop-loss coverage caps your exposure at the individual level (specific stop-loss) and sometimes at the aggregate level (aggregate stop-loss). If a single employee's medical costs exceed the specific stop-loss attachment point, the stop-loss carrier takes over that claim. Your financial question is: in a worst-case year, how much above your expected health plan budget can you go before it creates a real operational problem?

A reasonable working threshold for most mid-size employers: if your business cannot absorb a 15 to 20% increase in total health plan spending in a difficult claims year, you need either broader aggregate stop-loss coverage or a more structured funding design. If you can absorb that range without significant operational impact, you have meaningful flexibility in how you structure the plan and where you set attachment points.

This does not mean alternative funding is too risky if your exposure tolerance is limited. It means the stop-loss design needs to be calibrated to your actual tolerance before you sign anything, and any advisor presenting alternatives who does not ask this question explicitly is skipping a critical step in the analysis.

Question 3: Does Your Current Plan Structure Create Compliance Gaps You Have Not Addressed?

Many mid-size employers assume that a fully insured plan means the carrier handles compliance. In practice, certain employer obligations exist regardless of plan type. If these have not been addressed, a move to alternative funding may surface gaps that have been accumulating quietly under the fully insured arrangement.

The most common compliance gaps at the 20 to 100 employee level include three specific items. First, the Summary Plan Description: as the plan sponsor, you are required to provide employees with a current SPD. Carriers typically provide a coverage booklet that functions as an SPD, but the legal responsibility for distributing it and keeping it updated rests with the employer. Many employers have not formally distributed an updated SPD in several years. Second, ACA Applicable Large Employer status: companies with 50 or more full-time-equivalent employees have specific ACA obligations, including the requirement to offer minimum essential coverage meeting affordability standards. If your company is approaching or has crossed the 50 FTE threshold, your compliance picture changes significantly. Third, Mental Health Parity compliance documentation: the Mental Health Parity and Addiction Equity Act requires your plan to provide mental health and substance use disorder benefits that are not more restrictive than medical and surgical benefits, and compliance documentation obligations fall on the employer, not the carrier.

None of these gaps disappear if you stay on a fully insured plan. They are plan sponsor obligations that exist regardless of funding type. But they often surface during a move to alternative funding because a new TPA's onboarding process checks for them systematically. Knowing your compliance status before that conversation starts puts you in a much better position.

Question 4: What Does Your Workforce Actually Use in the Plan You Are Paying For?

Most employers have never looked at a utilization breakdown of their health plan. They know the overall claims number, but not where those claims come from. In practice, utilization patterns frequently reveal plan design mismatches that cost money without delivering commensurate value to employees.

A standard carrier claims report breaks spending into five categories: inpatient hospital stays, outpatient procedures and imaging, physician visits, pharmacy, and behavioral health. Employers who run this analysis often find that two of these five categories account for 70% or more of total claims. If you are paying for a comprehensive plan with a broad network but 80% of your claims are outpatient and pharmacy, you may be carrying benefits structure your workforce rarely uses at meaningful cost.

This is not a recommendation to eliminate certain benefit categories. It is a recommendation to make plan design decisions based on how your specific group actually uses the plan, rather than defaulting to whatever the carrier recommends for your employee count bracket. Utilization data also helps in conversations about plan design changes: when employees understand that the plan is being calibrated to how they actually seek care, the conversation about design trade-offs tends to land differently than a pure cost-cutting discussion.

How to Calculate Your Claims Volatility Score from Data You Already Have Access To

What to Request from Your Carrier or Broker Before Renewal

To calculate your claims volatility, request a monthly claims summary from your broker or directly from your carrier. This is standard data that carriers maintain, and plan sponsors are entitled to request it. Ask specifically for total incurred claims by calendar month for the last 24 months, a breakdown by claim category (medical, pharmacy, behavioral health), and enrolled member counts by month so you can calculate per-member figures for comparison.

If your broker has not proactively provided this data at mid-year or before renewal, asking for it is itself a diagnostic signal. Advisors who are working in your long-term interest routinely surface claims data at natural check-in points, not only when asked. If the request is met with friction or delay, you now know something useful about the advisory relationship you are in.

The Volatility Calculation That Changes the Conversation

Once you have monthly claims data, the calculation takes four steps:

1. Calculate your average monthly claim over the full period (add all months and divide by the number of months).
2. Identify the single highest-spending month and the single lowest-spending month.
3. Calculate the range (highest month minus lowest month).
4. Divide the range by your average. This gives you a volatility ratio as a percentage.

Example A: A 65-person employer has $52,000 in average monthly claims. Their highest month was $78,000 and their lowest was $31,000. The range is $47,000. Dividing $47,000 by $52,000 gives a volatility ratio of 90%. That is extremely high, almost certainly driven by one or two high-cost claimants in the high months. This group needs carefully structured specific stop-loss coverage before self-funding or level-funding makes financial sense.

Example B: A second 65-person employer with the same $52,000 average has a high of $63,000 and a low of $42,000. The range is $21,000. Dividing $21,000 by $52,000 gives a volatility ratio of 40%. This group is a reasonable candidate for level-funded evaluation, with a specific stop-loss attachment in the $40,000 to $60,000 range likely producing competitive economics while capping downside exposure.

A ratio below 25% indicates a very stable group that is almost certainly a strong candidate for alternative funding. A ratio of 25 to 50% warrants a careful stop-loss design conversation. Above 50%, the group may be better served staying on a fully insured arrangement until the high-cost drivers resolve or the group grows enough to absorb that variance more comfortably.

Reframing Alternative Funding as a Lateral Transfer of Functions, Not a New Risk

One of the most persistent barriers to exploring alternative funding is the perception that self-funded or level-funded plans require the employer to take on new risk the carrier was previously absorbing. That framing is partly accurate, but it misrepresents how the risk is actually structured and what changes operationally when you move.

What Your Carrier Handles on Your Behalf in a Fully Insured Plan

In a fully insured plan, your carrier handles claims adjudication, network contract management, coverage determination, member dispute resolution, and most ACA reporting functions. These are real services, and the carrier charges for them through the administrative component of your premium. According to data from the Kaiser Family Foundation's 2024 Employer Health Benefits Survey, the administrative loading on typical fully insured commercial plans ranges from 18% to 30% of total premium for small and mid-size employer groups.

That loading does not disappear when you move to a self-funded or level-funded arrangement. It moves to a third-party administrator, whose administrative fee is typically disclosed as a per-member-per-month charge rather than embedded in an opaque premium. For many groups, this disaggregation is itself a financial benefit: you can see exactly what you are paying for administration, and you can compare that fee across multiple TPAs before you commit.

What Moves and What Stays When You Switch to an Alternative Structure

When you move to a self-funded or level-funded plan, the administrative functions do not go away. They migrate to different vendors. Claims adjudication moves from the carrier to a TPA. Network access moves from the carrier's network to a leased network (your TPA typically has access to one or more major national networks, often the same ones the carrier uses). Stop-loss coverage shifts from implied pooling in the carrier's book to an explicit stop-loss contract with a specific attachment point and carrier you can evaluate independently.

What does change directly: some compliance filings become your direct obligation. Self-funded plans with more than 100 participants must file Form 5500 annually with the Department of Labor. The PCORI fee (an ACA-related fee based on covered lives) is paid directly by self-funded plan sponsors, not through the carrier. And your relationship with stop-loss becomes explicit and negotiable rather than implicit.

What does not change, assuming comparable network access and plan design: your employees' day-to-day experience using the plan. In a well-executed transition to self-funding or level-funding, most employees see no change in their network access, ID cards, or claims process. The change is structural and financial, not experiential for the covered workforce.

A Health Plan Risk Profile Matrix for Employers with 20 to 100 Employees

The following framework maps common group risk profiles to starting points for funding evaluation. These starting points are not recommendations; they are the beginning of a conversation, not the end of one. Every group's actual situation requires a full analysis before any recommendation can be validated.

Group Profile	Volatility Range	Exposure Tolerance	Where to Start
Stable, predictable claims history	Below 25%	Can absorb 15 to 20% swing	Level-funded or multiemployer trust
Stable group with tight cash position	Below 25%	Limited, below 10%	Level-funded with broad aggregate stop-loss
High volatility, known high-cost claimant	Above 50%	Any level	Fully insured or PEO-bundled plan; revisit in 12 months
Moderate volatility, willing to model alternatives	25 to 50%	Can absorb 15 to 20% swing	Self-funded with low specific stop-loss attachment
Service industry, high-turnover workforce	Variable	Any level	Multiemployer trust or PEO-bundled plan
Multi-location, complex workforce mix	Variable	Any level	Dedicated-service PEO with multi-plan design capability

Note that multiemployer trust plans (sometimes called Taft-Hartley plans) appear in two of the six scenarios above. These nonprofit trust structures pool risk across unrelated employers and typically run administrative overhead of 10 to 15%, compared to 18 to 30% for commercial fully insured plans. For service-industry groups with high turnover or variable workforce composition, multiemployer trusts often provide more stable renewals than commercial alternatives, because trust experience is based on the full pool rather than individual group claims. They are not available to every employer, but they deserve a specific evaluation for groups that fit the profile.

How This Assessment Changes What Happens at Your Next Renewal

What Most Employers Bring to a Renewal Meeting

The typical renewal conversation starts with a number: a percentage increase from the carrier, a comparison of two or three plan options within the same fully insured structure, and a recommendation from the broker about which plan to choose. The employer's role is to react to those options. The carrier defined the framework. The broker filled in the specifics. The employer responds.

This is not a criticism of brokers or carriers. It is a description of how the process works when the employer has not done independent analysis before the meeting. Without your own data in hand, you are evaluating the carrier's options using the carrier's framing. That is a structurally weak negotiating position.

What Employers Who Run This Assessment Bring Instead

An employer who has worked through the four questions above arrives at renewal knowing their volatility score, their exposure tolerance threshold, at least two compliance status items, and their utilization breakdown by category. They can ask specifically: "Given our volatility profile and loss ratio, what alternative funding arrangements have you quoted alongside this renewal?" If the broker cannot answer that question with actual quote data, the employer now knows the conversation they should be having and whether this advisor is the one to have it with.

Employers who run this kind of structured self-assessment before renewal consistently report that the conversation changes in quality, not just in outcome. They are evaluating options against criteria they defined independently, rather than reacting to what a carrier chose to present. For a fuller view of what alternative funding structures look like in practice, the overview of six health coverage funding strategies for mid-size employers at BENEFITRA walks through the full landscape side by side.

If you have not benchmarked your current plan spending against similarly-sized employers in your industry, the Employee Benefits Benchmarking guide at BENEFITRA gives you a starting point for that comparison, using data from the Kaiser Family Foundation's annual employer survey and SHRM compensation studies. Understanding where you sit relative to the market before you enter a renewal conversation is the second half of the preparation this assessment provides.

Frequently Asked Questions

What is a health plan risk assessment and why should mid-size employers do one?

A health plan risk assessment is a structured review of your group's claims history, financial exposure tolerance, compliance status, and workforce utilization patterns, done before you evaluate funding options at renewal. Most employers skip this step and react to whatever the carrier presents. Employers who do this assessment arrive at renewal with specific criteria for evaluating options rather than choosing between options someone else defined. The process typically takes an afternoon and uses data available from your carrier upon request.

How do I know if my group is a good candidate for level-funded or self-funded health coverage?

The two strongest indicators are a low claims volatility score (monthly claims swinging less than 25% above and below your average) and a favorable loss ratio (total claims at or below 75 to 80% of total premium). Groups that meet both criteria are almost always worth quoting in a level-funded or self-funded structure, because the pooling mechanism in a fully insured plan is providing them little benefit while charging them for pool-wide administrative overhead. Groups with higher volatility may still qualify, but the stop-loss design becomes more critical and requires more careful structuring.

What is a multiemployer trust and how is it different from a regular group health plan?

A multiemployer trust (also called a Taft-Hartley trust) is a nonprofit pool of employers that collectively fund their health benefits through a trust governed by a board of trustees. Because there is no carrier profit motive, every premium dollar goes toward claims, administration, or reserves. Administrative overhead ratios in multiemployer trusts typically run 10 to 15%, compared to 18 to 30% for commercial fully insured plans. Renewal increases are tied to the trust's own claims experience rather than commercial market trend, which often produces more stable year-to-year pricing for employers in the right size and industry profile.

Will switching to an alternative funding arrangement change anything for my employees?

In a well-executed transition, most employees see no change in their day-to-day experience: the same network access, the same coverage structure, the same claims process. What changes is structural and financial, not experiential. Your employees may receive new ID cards and the TPA's contact information for claims questions, but the networks they use, the benefits they receive, and the cost-sharing structure can remain identical to the prior plan. The key is ensuring that network access is maintained during the transition, which a qualified TPA handles as part of the onboarding process.

How often should we review our health plan risk profile?

At minimum, annually, and ideally 90 days before your renewal date. That timing gives you enough runway to act on what you find before the carrier assumes you are renewing at the offered rate. Running a mid-year claims review six months into your plan year is even better: if a high-cost claimant has emerged, you can start planning. If your claims are tracking well below projections, you can begin exploring alternative funding options proactively rather than reactively. Employers who review claims data twice per year consistently report better renewal outcomes than those who engage only at the deadline.

What if we have a known high-cost claimant? Does that rule out alternative funding?

Not automatically, but it changes the analysis significantly. Most level-funded carriers will price around a known high-cost condition rather than exclude the employee. The stop-loss attachment point is typically set lower to account for the known risk, which increases the stop-loss component of your premium. In some cases, the overall economics still favor alternative funding over fully insured, especially if the rest of your group has favorable claims. In others, the fully insured pool is the right structure until the condition resolves or the group reaches a size where self-funding of that risk becomes more practical. The only way to know is to get actual quotes with the condition fully disclosed. You can also use the Health Funding Projector to model different stop-loss scenarios and see how they affect the overall cost comparison.
