If you’re a Washington business owner or HR director comparing self-funded vs level-funded health plans, you’re asking the right question at the right time. With Washington State health insurance renewals averaging 21.2% increases heading into 2026, sticking with a traditional fully insured plan means absorbing costs that are rising far faster than revenue. Both self-funded and level-funded plans offer a path out of that cycle, but they work differently and suit different companies.
This guide breaks down how each funding model works, what they cost, and how to decide which one is the right fit for your Washington business. Whether you lead a 25-person firm or a 300-employee organization, the funding strategy you choose can mean the difference between a predictable budget and tens of thousands in unexpected costs.

What Is a Self-Funded Health Plan?
A self-funded (or self-insured) health plan is an arrangement where your company pays employee health claims directly instead of paying fixed premiums to an insurance carrier. You assume the financial risk for your employees’ healthcare costs, but you also keep the savings when claims come in lower than expected.
How Self-Funding Works
Under a self-funded plan, your company sets aside funds each month to cover anticipated claims. A third-party administrator (TPA) handles claims processing, network access, and plan administration. To protect against catastrophic claims, you purchase stop-loss insurance with two layers of coverage:
- Specific stop-loss: Caps the maximum your company pays for any single employee’s claims in a year (typically $50,000 to $150,000 per person)
- Aggregate stop-loss: Caps total claims for your entire group, usually at 125% of expected claims
The result is that your company pays actual healthcare costs rather than inflated premiums that include carrier profit margins, premium taxes, and risk loading. When your team is healthy and claims run below projections, your company keeps the surplus.
What Self-Funded Plans Cost
Self-funded plans eliminate several embedded costs that fully insured plans carry. Here is where the savings come from:
- No premium tax: Fully insured plans include a 2-3% state premium tax. For a company spending $800,000 annually, that is $16,000 to $24,000 eliminated immediately.
- No carrier profit margin: Insurance companies build 3-8% profit margins into premiums. Self-funding removes that layer entirely.
- No risk loading: Carriers price conservatively to protect against bad years. Self-funded plans let you pay based on your own claims experience.
- Transparent pharmacy costs: Pairing self-funding with a transparent pharmacy benefit manager eliminates hidden PBM spreads that typically add 15-25% to pharmacy spend.
In total, Washington businesses that move from fully insured to self-funded plans typically see 20-35% cost reductions in their first year.
What Is a Level-Funded Health Plan?
A level-funded health plan is a hybrid model that blends elements of both fully insured and self-funded plans. You pay a fixed monthly amount (like a fully insured plan), but your payment is divided into three distinct buckets: administrative costs, stop-loss premiums, and a claims fund. If your employees’ actual claims come in below the funded amount, you receive a refund of the surplus.
How Level-Funding Works
Each month, your company pays a set per-employee amount to the carrier or TPA. That payment breaks down like this:
- Administrative fees: Covers claims processing, network access, compliance support, and plan management
- Stop-loss premium: Provides both specific and aggregate stop-loss protection, capping your maximum financial exposure
- Claims fund: The largest portion, set aside to pay actual employee health claims throughout the year
At year-end, the carrier compares actual claims against the claims fund. If claims were lower than projected, you get money back. If claims exceed the fund, the stop-loss coverage absorbs the overage. Your monthly payments never increase mid-year regardless of claims activity.
What Level-Funded Plans Cost
Level-funded plans deliver meaningful savings over fully insured options while limiting your downside risk. According to recent industry data, employers on level-funded plans pay 15-25% less than comparable fully insured plans, with UnitedHealthcare reporting that plan sponsors pay 19% less on average under their level-funded products.
The adoption trend tells the story: among small firms with 3-199 employees, enrollment in level-funded plans surged from 7% in 2019 to 38% in 2023, according to the Kaiser Family Foundation. Washington businesses have been part of that shift, driven by the same cost pressures affecting employers nationwide.
Self-Funded vs Level-Funded: Side-by-Side Comparison
The table below compares the key differences between self-funded and level-funded health plans for Washington businesses:
| Feature | Self-Funded | Level-Funded |
|---|---|---|
| Monthly costs | Variable based on actual claims | Fixed monthly payments |
| Savings potential | 20-35% vs fully insured | 15-25% vs fully insured |
| Financial risk | Higher (mitigated by stop-loss) | Lower (built-in stop-loss) |
| Cash flow predictability | Less predictable month-to-month | Fully predictable |
| Claims data access | Full transparency | Moderate transparency |
| Plan customization | Highly customizable | Some customization available |
| Surplus refund | You keep all surplus | Partial refund if claims are low |
| Ideal company size | 50-300+ employees | 20-100 employees |
| Administrative burden | Higher (TPA management required) | Lower (carrier handles most admin) |
| State premium tax | Exempt (ERISA-governed) | Varies by state and structure |
Which Funding Model Fits Your Washington Business?
The right choice depends on your company’s size, financial stability, risk tolerance, and how much control you want over your benefits program. Here is how to think about each option based on your situation.
Choose Self-Funded If Your Business Has:
- 50 or more employees: Larger groups create a more predictable risk pool. With 50+ employees, your claims experience becomes statistically meaningful, making self-funding more reliable.
- Strong cash reserves: You need the ability to absorb claims fluctuations month-to-month, even with stop-loss protection in place.
- A desire for maximum control: Self-funded plans let you design benefits from scratch, choose your own TPA and PBM, and make changes mid-year without carrier approval.
- Interest in advanced strategies: Self-funding is the foundation for layering additional cost-saving tactics like first-dollar HRAs, reference-based pricing, and transparent PBM contracts.
Choose Level-Funded If Your Business Has:
- 20-75 employees: Level-funding was designed for smaller groups that want to escape fully insured pricing without taking on full self-funded risk.
- A relatively healthy workforce: Since refunds depend on claims coming in below projections, companies with younger or healthier employee populations benefit most.
- Budget predictability as a priority: If your CFO needs to know exactly what benefits will cost each month, level-funding delivers that certainty.
- Limited internal HR resources: Level-funded plans require less hands-on management than fully self-funded arrangements.
The Overlap Zone: 50-100 Employees
Companies in the 50 to 100 employee range often have a genuine choice between both models. This is where the decision comes down to your company’s financial philosophy and risk appetite. A Washington business with 75 employees, strong cash flow, and a healthy workforce might save more with self-funding. The same company with tighter margins might prefer the predictability of level-funding while still capturing 15-25% savings over their fully insured renewal.
The best approach is to model both scenarios using your company’s actual claims data and demographics. A broker with expertise in both funding strategies can run these projections and show you the real numbers, not hypothetical averages.

Cost Savings in Action: What Washington Employers Can Expect
To put these numbers in context, here is what a typical Washington business might save under each model.
Example: 100-Employee Washington Company
Assume a company currently paying $1.2 million annually for a fully insured group health plan:
- Self-funded savings: 20-35% reduction = $240,000 to $420,000 in annual savings, plus full claims transparency and the ability to layer in transparent PBM and HRA strategies for additional reductions
- Level-funded savings: 15-25% reduction = $180,000 to $300,000 in annual savings, with the potential for a year-end surplus refund if claims are favorable
Even at the conservative end, either funding strategy puts six figures back into the business. For many Washington companies, that is the equivalent of hiring two or three additional employees or funding a significant capital investment.
Why These Savings Exist
Both models save money for the same fundamental reason: they remove layers of cost that fully insured plans build into every premium dollar. When you pay a fully insured premium, you are covering the insurance carrier’s profit margin, premium taxes, conservative risk loading, and administrative overhead on top of your employees’ actual healthcare costs. Alternative funding strategies strip away those layers and let you pay closer to the true cost of care.
The key difference is how much of that savings you can capture. Self-funded plans offer the maximum upside because you retain full control and keep all surplus. Level-funded plans trade some of that upside for downside protection and budget predictability.
Common Concerns About Alternative Funding
What if we have a catastrophic claim?
Both self-funded and level-funded plans include stop-loss insurance specifically designed to handle this scenario. Specific stop-loss caps the cost of any single high-dollar claim, while aggregate stop-loss limits your total annual exposure. A properly structured plan ensures that one expensive claim does not blow up your budget.
Is our company too small to self-fund?
Traditional self-funding typically works best with 50+ employees, but group captive arrangements now make self-funding accessible to companies with as few as 25 employees. In a captive, multiple small employers pool their risk while each maintaining their own plan design. If you have fewer than 50 employees, level-funding is usually the more practical starting point.
Will employees notice a difference?
In most cases, no. Employees use the same provider networks, carry the same ID cards, and experience the same claims process. The funding mechanism is a back-office decision that affects how the employer pays for coverage, not how employees access care. If anything, companies that move to alternative funding often improve their benefits because the cost savings create room to enhance plan design.
How do we get started?
Transitioning to self-funded or level-funded coverage starts with analyzing your current plan’s claims history, employee demographics, and risk profile. A qualified benefits advisor can model both options using your actual data and recommend the approach that maximizes savings while keeping risk at a level your company is comfortable with.
Why Your Broker Matters More Than Your Funding Model
Here is a truth that most articles on this topic miss: the funding model you choose matters less than the broker who implements it. A self-funded plan designed by a broker who lacks expertise in alternative funding can cost more than a well-structured fully insured plan. The strategy only works when someone with deep knowledge of claims analysis, stop-loss placement, TPA selection, and pharmacy management is guiding the process.
This is where many Washington businesses run into problems. National brokerages with thousands of clients default to fully insured renewals because that is the easiest transaction to process at scale. They lack the incentive and often the expertise to evaluate whether self-funding or level-funding would save their clients money.
At Washington Health Insurance Agency, advanced funding strategies are a core specialty, not an afterthought. With over 26 years of experience serving Washington businesses with 20-300 employees, WHIA evaluates every funding option available, including self-funded, level-funded, captive, and hybrid approaches. Every client receives a comprehensive market analysis comparing plans from 20+ carriers, with transparent recommendations backed by a guaranteed ROI: a minimum of $5,000 in demonstrated savings, or WHIA refunds its $2,500 advisory fee.
That kind of alignment does not exist with traditional commission-based brokers who earn more when your premiums go up. WHIA’s fixed-fee model means the agency succeeds only when your costs go down.
Next Steps: Find the Right Funding Strategy for Your Business
Choosing between self-funded and level-funded health plans is not a decision you need to make alone. The right approach depends on your company’s specific claims history, workforce demographics, financial position, and risk tolerance. Getting it right can save your Washington business hundreds of thousands of dollars. Getting it wrong can create unnecessary risk or leave savings on the table.
If you are evaluating your health plan funding options and want a clear, data-driven comparison tailored to your company, schedule a consultation with WHIA to see what self-funded or level-funded coverage could save your business. There is no obligation, and if WHIA cannot demonstrate at least $5,000 in savings, you pay nothing.

Frequently Asked Questions
What is the difference between self-funded and level-funded health plans?
A self-funded plan means your company pays employee health claims directly and assumes the financial risk, offset by stop-loss insurance. A level-funded plan is a hybrid where you pay fixed monthly amounts that include claims funding, administration, and stop-loss. If claims are low, you receive a refund. Self-funded plans offer higher savings potential but more risk; level-funded plans offer predictable costs with moderate savings.
How many employees do you need for a self-funded health plan?
Traditional self-funded plans work best for companies with 50 or more employees, which creates a statistically reliable risk pool. However, group captive arrangements now allow companies with as few as 25 employees to access self-funding benefits. For businesses with 20-50 employees, level-funded plans are typically the better starting point.
Are self-funded health plans legal in Washington State?
Yes. Self-funded health plans are governed by the federal Employee Retirement Income Security Act (ERISA), which preempts most state insurance regulations. This means self-funded plans in Washington are exempt from state premium taxes and many state-mandated benefit requirements, which is one reason they cost less than fully insured plans.
Can you switch from fully insured to self-funded or level-funded?
Yes. Most companies transition at their annual renewal date. The process involves analyzing your current claims history, selecting a TPA or level-funded carrier, designing your plan, and purchasing stop-loss coverage. A knowledgeable benefits broker can manage the entire transition with minimal disruption to employees. Your employees typically keep the same providers and networks.
What happens if claims exceed the budget in a level-funded plan?
The stop-loss insurance built into every level-funded plan covers claims that exceed projections. Your monthly payments stay the same regardless of claims activity during the plan year. The carrier absorbs the excess risk, which is why level-funded plans are considered lower risk than fully self-funded arrangements.
