The Six Health Coverage Funding Strategies That Mid-Size Employers Almost Never Hear About

Most employers shopping for group health coverage get quotes from one or two funding arrangements. A fully insured plan from a major carrier, maybe a level-funded option if the broker knows to suggest it. The conversation starts and ends there, and the employer signs for another year without ever knowing what they were not shown.

There are actually six distinct health coverage funding strategies available to mid-size employers with 20 to 250 employees. Most brokers specialize in one or two of them. A small number work fluently across three or four. Very few bring all six to the table. The difference matters, because the right funding strategy for your workforce is not always the one your current broker quoted, and the wrong one can cost your company tens of thousands of dollars per year in premiums that never come back to you.

This guide explains all six health coverage funding strategies in plain language: how each one works, which type of employer it fits best, and what to ask your benefits advisor to find out whether you have ever seen the full set of options.

Why Most Employers Only Hear About One or Two Health Coverage Funding Strategies

How the Broker Market Is Structured

Brokers are typically contracted with a limited set of carriers and administrators. Their compensation structures, carrier relationships, and product expertise all shape what ends up on the comparison spreadsheet you receive at renewal time. This is not necessarily a conflict of interest issue, it is a market structure issue. A broker who built their book of business on fully insured plans through two or three major carriers has deep expertise in those products. They may have less fluency with level-funded administrators, captive structures, or PEO arrangements simply because those products are not their primary market.

When you ask "what are my options for this year," you tend to get a filtered answer. That filter reflects what your broker actually knows and sells, not the full landscape of what is available to a company at your size and stage. For most mid-size employers, this means the funding conversation never happens, and the renewal becomes a negotiation about which fully insured plan to choose rather than whether the fully insured model is right at all.

The Cost of Not Knowing Your Options

For employers with 20 to 250 employees, choosing the right funding strategy can reduce effective health coverage costs by 10 to 30 percent compared to a default fully insured renewal. An employer paying $900,000 per year on fully insured premiums who discovers that a level-funded arrangement saves 15 percent is looking at $135,000 in annual savings. Compounded over five years, that is a significant number. It stays invisible if the broker only quotes the fully insured market.

According to the Kaiser Family Foundation 2024 Employer Health Benefits Survey, average employer-sponsored family premiums rose 7 percent in 2024 and have climbed 24 percent over the past five years. Employers who benchmark against multiple funding strategies every year consistently find better renewal outcomes than those who renew within the same structure by default.

The Six Health Coverage Funding Strategies Mid-Size Employers Should Know

Strategy 1: Fully Insured

The most familiar arrangement. Your company pays a fixed monthly premium to a commercial carrier. The carrier assumes all financial risk for your employees' medical claims and handles plan administration, network contracting, and claims payment. Your financial exposure is limited to the monthly premium, which is predictable and consistent throughout the plan year.

Fully insured plans pool your group with thousands of others across the carrier's book of business. Your claims history has limited impact on your renewal rate because the carrier blends your individual group performance with pool-wide experience. If your group runs a favorable claims history year after year, the carrier retains that financial upside. You still absorb the full pool-wide trend increase at renewal, typically 7 to 15 percent annually.

If you want to understand how your loss ratio compares to what carriers typically keep, the analysis of health plan claims reports explains what that data actually means for your renewal position.

Best fit: groups under 25 employees, new companies with no claims history, employers with high claims variance or recent large claims who need pooling protection.

Strategy 2: Level-Funded

A level-funded plan looks like a fully insured plan from a cash flow perspective. You pay a fixed monthly amount that covers expected claims, stop-loss protection, and administration costs. The structure is fundamentally different, though: you are funding a claims account rather than paying premiums into a carrier pool.

At year end, if your actual claims come in below the projected amount, you receive a surplus refund. Most level-funded arrangements return 50 to 100 percent of unused claims dollars, depending on plan design. If claims exceed the projection, your stop-loss coverage caps the exposure at the attachment point set in the plan.

Level-funded plans are available to employers with as few as 5 employees in some markets, though the economics typically become compelling starting at 25 to 50 employees. They are one of the fastest-growing funding arrangements in the mid-market because they give smaller employers some of the financial upside previously available only to large, self-funded corporations.

Best fit: employers with 25 to 150 employees, stable workforce, favorable or average claims history, and interest in capturing some financial upside without full self-funding complexity.

Strategy 3: Self-Funded

In a fully self-funded arrangement, the employer pays actual medical claims directly rather than paying premiums to a carrier. The employer contracts with a third-party administrator to handle network access, claims processing, and plan administration. Stop-loss coverage protects against catastrophic individual claims or an unexpectedly difficult aggregate year for the group.

Self-funding offers maximum transparency: you see exactly what your workforce spends on healthcare, broken down by category and cost. Every dollar goes toward actual claims, administration, or stop-loss. There are no carrier profit margins or reserve contributions embedded in your monthly cost. According to SHRM research on self-funded arrangements, self-funding typically reduces health plan costs by 15 to 30 percent for groups with favorable claims histories, compared to fully insured alternatives.

The tradeoff is cash flow variance. A single high-cost claimant can create a significant short-term budget impact even with stop-loss protection. Self-funding requires more administrative involvement and a higher tolerance for claims variance than level-funded or fully insured plans. It works best for companies with a dedicated HR or finance team that can manage claims data actively.

Best fit: employers with 50 to 250 employees, stable and moderately healthy workforce, finance or HR team comfortable managing claims data, and a multi-year planning horizon.

Strategy 4: Reference-Based Pricing

Reference-based pricing replaces traditional carrier network rate-setting with a reimbursement methodology tied to a benchmark rate, typically a percentage of what Medicare pays for the same service. Instead of negotiated rates set by a carrier network, providers are reimbursed at a set multiple of Medicare, often 140 to 200 percent of the Medicare rate depending on the program.

Reference-based pricing can generate meaningful cost reductions, particularly for hospital-based services where carrier network rates often run 200 to 400 percent of Medicare. The tradeoff is that some providers do not accept reference-based payment as payment-in-full and may pursue balance-billing of employees for the difference. A well-designed reference-based pricing plan includes employee advocacy services to handle billing disputes before they become problems for your workforce.

For a deeper comparison of how reference-based pricing compares to level-funded, the level-funded versus reference-based pricing guide covers the tradeoffs in more detail.

Best fit: employers with workforce concentrated in geographic areas with strong provider competition, leadership willing to support employees through occasional billing disputes, and a benefits consultant with deep reference-based pricing expertise.

Strategy 5: Group Captive

A group captive pools health coverage risk with other non-competing employers through a shared structure. Typically 10 to 30 employers join a captive together, each contributing to a shared risk layer while separately funding their own claims up to a per-employer retention limit. Losses that exceed any single employer's retention are shared across the captive group, and stop-loss coverage handles catastrophic individual events.

Captives are designed to stabilize renewal pricing and allow employers to build equity in the shared risk pool over time. Members who run favorable claims histories benefit directly from that performance, rather than subsidizing a commercial carrier pool. The self-funded captive guide for mid-market employers explains the qualification criteria and what the equity-building process looks like over time.

Captive structures typically require a multi-year commitment, often three to five years, to realize the full financial benefit. Employers who exit early forfeit equity they have built in the shared risk pool. For employers with a long-term benefits strategy and a stable workforce, captives offer a compelling path to the cost economics of self-funding without the full claims volatility of going solo.

Best fit: employers with 50 to 250 employees, clean to average claims history, multi-year benefit planning horizon, and a benefits advisor with captive market access.

Strategy 6: PEO and Multiemployer Trust

A professional employer organization, or PEO, pools your employees with thousands of other small and mid-size companies into a single large benefit plan. Because of the aggregate size, PEOs access carrier and network rates typically available only to employers with hundreds or thousands of employees. According to NAPEO industry research, employers in PEO arrangements average 20 to 35 percent lower health coverage costs than comparable employers purchasing coverage independently.

A related structure, the multiemployer trust or Taft-Hartley trust, pools risk across employers through a nonprofit trust rather than a commercial carrier. Because the trust has no profit motive, every premium dollar goes toward claims, administration, or reserves. Renewal increases in multiemployer trusts are tied to actual trust claims experience, not commercial market pricing cycles, which historically produces lower and more stable renewal trends for qualifying employer groups.

PEO arrangements also include HR administration, payroll processing, and compliance functions, which can meaningfully reduce administrative costs for growing companies. For employers with 20 to 100 employees who want large-company benefit quality without the complexity of self-funding, the PEO model is frequently the most economical starting point.

Best fit: employers with 20 to 100 employees seeking enterprise-grade benefits without self-funding complexity, industries with high workforce turnover or mixed health profiles, companies that also want to simplify HR and payroll administration.

How to Figure Out Which Strategy Fits Your Company

Start With Your Claims History

Your claims history is the single most important input into the funding strategy decision. Request your annual claims experience report from your current carrier and calculate your loss ratio by dividing total incurred claims by total premium collected. A group consistently running below 75 percent has strong financial incentive to explore arrangements where that favorable performance generates a return. A group with one or two high-cost claimants in recent years may benefit from carrier pool protection through the fully insured or level-funded model.

The loss ratio calculation is straightforward: total incurred claims divided by total premium paid. A result of 68 percent means 68 cents of every premium dollar went to actual healthcare. The other 32 cents stayed with the carrier. In a level-funded or self-funded arrangement, most of that 32 cents would have come back to your company at year end.

Factor In Group Size and Risk Tolerance

Size matters in funding strategy selection. Fully insured is the right default for very small groups and new companies with limited history. Level-funded becomes economically compelling at 25 to 50 employees. Self-funding and captives tend to work best above 50 to 75 employees where the risk pool is large enough to provide some natural claims smoothing. PEO and multiemployer trust arrangements deliver strong economics across all sizes but are particularly compelling at 20 to 100 employees where independent purchasing power is lowest.

Risk tolerance is the other variable. Self-funding and reference-based pricing carry more operational complexity and require more active management. Level-funded and captive arrangements land in the middle: more financial upside than fully insured, more administrative involvement than staying in the carrier pool. There is no universally right answer, but there is almost always a better answer than what a single-broker, single-carrier renewal process produces.

Questions to Ask Your Benefits Advisor

When you go into your next renewal meeting, bring these specific questions:

• Which of the six health coverage funding strategies have you quoted for our group this year, and which ones did you rule out, and why?
• What is our three-year average loss ratio, and what does that tell you about where we sit relative to the fully insured pool?
• Do you have access to level-funded administrators, captive structures, and PEO arrangements, or do you primarily work with fully insured carriers?
• What is your compensation structure for each funding type you might recommend, and does it vary by strategy?

The answers will tell you a great deal about whether your current advisor can show you the full range of options, or whether a second opinion would surface strategies you have never seen quoted.

Real Scenarios: Matching the Strategy to the Company

The Service Industry Employer with Long-Tenured Employees

A 90-employee senior care or hospitality company with employees who have been on the team for 10 to 30 years has a different risk profile than a startup with high turnover. Long-tenured employees often have older, more stable medical utilization patterns, but they also have predictable claims that make risk modeling more reliable. For this profile, a level-funded arrangement with well-designed stop-loss, or a multiemployer trust plan, frequently outperforms the commercial fully insured market because the employer stops subsidizing the carrier pool and starts capturing surplus on favorable years.

The Professional Services Firm with a Younger Workforce

A 45-employee software or marketing firm with mostly employees under 35 and low medical utilization is exactly the profile that commercial carriers profit from. The right move in this case is almost certainly level-funded, where a healthy workforce's unused claims dollars come back to the company at year end rather than the carrier. A reference-based pricing overlay can amplify the savings if the workforce is concentrated in a metro area with strong provider competition.

The Mid-Size Manufacturer Approaching 100 Employees

A manufacturing or construction company at 80 to 100 employees has enough scale for self-funding but faces real claims variance from a physical workforce. A group captive structure offers a path that most brokers never present: shared risk pooling with other employers in similar industries, cost transparency, and the ability to build equity in the risk pool over time without taking on the full volatility of going fully self-funded alone.

Frequently Asked Questions

What is the most common health coverage funding strategy for employers with 20 to 50 employees?

Fully insured plans remain the most common choice for employers in this size range, primarily because most brokers default to the fully insured market and small group purchasing has historically been limited to carrier products. However, level-funded plans have grown rapidly in this segment over the past five years, as more administrators have built products accessible to groups as small as 5 to 10 employees. For employers in the 20 to 50 range with stable, favorable claims histories, level-funded is increasingly the better economic choice, though it requires a broker who works in that market to surface it.

Can a small employer self-fund their health coverage?

Technically yes, but practically the economics typically require at least 50 employees to make fully self-funded plans work without excessive claims volatility. Smaller employers can access some of the same benefits through level-funded arrangements or PEO plans, which provide the financial transparency and surplus-sharing features of self-funding within a structure that pools risk and provides more predictable monthly costs. The line between "level-funded" and "self-funded" has blurred significantly as the market has evolved, and some products marketed as level-funded operate very similarly to self-funded plans with a fixed claims ceiling.

How does a group captive differ from a multiemployer trust?

Both structures pool risk across multiple employers, but the legal and operational framework differs. A group captive is typically organized as a captive insurer, often domiciled offshore or in a captive-friendly state, where employers own shares in the shared risk entity. A multiemployer trust, or Taft-Hartley trust, is a nonprofit trust governed by a board of trustees representing both employers and employees. Multiemployer trusts have a longer history in union industries but have expanded into non-union mid-market applications. The core financial benefit is similar in both: favorable claims performance builds equity rather than carrier profit, and renewal increases reflect actual trust or captive experience rather than commercial market pricing.

What does reference-based pricing actually mean for my employees?

In a reference-based pricing plan, your employees can access most providers, including out-of-network hospitals, because the plan pays a defined rate tied to Medicare rather than a carrier-negotiated rate. For employees, this usually means broader access than a narrow-network HMO. The complication is balance billing: some providers, particularly large hospital systems, do not accept the reference-based rate as payment-in-full and send employees additional bills for the difference between the reference rate and their billed charges. A strong reference-based pricing plan includes a member advocacy team that negotiates or disputes these balance bills on the employee's behalf. When that advocacy function is robust, most balance-bill situations are resolved without cost to the employee. When it is not, employees can face unexpected out-of-pocket costs.

How often should employers benchmark their funding strategy?

At minimum, every renewal cycle, and ideally 90 to 120 days before the renewal date so you have enough time to get alternative quotes and actually act on them. Many employers fall into a pattern of renewing with the same carrier and structure year after year out of inertia, even as their company profile changes. A company that was fully insured at 30 employees and grew to 75 may be substantially overpaying by staying in the fully insured pool. Benchmarking annually ensures the funding strategy keeps pace with the company, not just the carrier's pricing model.

What is the first step if I think my employer is overpaying for health coverage?

Start by requesting your annual claims experience report from your current carrier and calculating your loss ratio. Divide total incurred claims by total premium paid for the last 12 months. If that number is below 75 percent, you have a strong case for exploring alternative funding arrangements. Bring that number to your next broker meeting and ask specifically which of the six funding strategies have been quoted for a group with your loss ratio history. If your broker has not quoted at least two or three alternatives, that is a useful data point. You can also use the Health Funding Projector at peo4you.com to model what different arrangements might look like for your group size and claims profile.
