Compare Health Insurance Options: Self-Funded, Level-Funded, and Fully-Insured Plans

When comparing health insurance options, the main difference lies in who assumes financial risk.

• Self-funded plans give employers full control and risk.
• Level-funded plans balance predictability with flexibility.
• Fully-insured plans shift all risk to the insurance carrier but often come at a higher long-term cost.

For HR leaders and business owners, health insurance decisions are among the most critical — and complex — choices in managing employee benefits. Between self-funded, level-funded, and fully-insured plans, it can be hard to know which structure aligns with your company’s size, risk tolerance, and financial strategy.

At Evergreen Benefits Group, we believe clarity builds confidence. In this guide, we simplify these three models, highlight key differences, and outline how a proactive funding strategy can help you manage costs, stay compliant, and support employee satisfaction.

What Is a Self-Funded Health Plan?

A self-funded health plan (or self-insured plan) is one where the employer pays for employee medical claims directly rather than paying fixed premiums to an insurance carrier.

How It Works

• Employer sets aside funds to pay for employee claims.
• A third-party administrator (TPA) often manages claims processing and compliance.
• Employers may purchase stop-loss insurance to limit exposure to catastrophic claims.

Pros

• Greater control over plan design and employee benefits.
• Access to detailed claims data for strategic cost management.
• Potential for significant long-term savings in low-claim years.

Cons

• Higher financial risk in years with unexpected claims.
• Requires active oversight and strong cash flow management.

Best For:

Mid-size to large companies (typically 100+ employees) with stable claims history and dedicated HR/finance teams.

What Is a Level-Funded Health Plan?

A level-funded insurance plan bridges the gap between fully-insured and self-funded options. Employers pay a predictable monthly amount — which covers expected claims, administrative fees, and stop-loss protection.

How It Works

• You pay a fixed monthly “level” amount.
• If claims are lower than expected, you may receive a refund.
• If claims are higher, stop-loss insurance covers the difference.

Pros

• Predictable monthly costs make budgeting easier.
• Employers can share in savings from lower claims.
• Offers transparency without full self-funding risk.

Cons

• Smaller refund potential if the plan is heavily utilized.
• May still involve administrative complexity compared to fully-insured plans.

Best For:

Growing small to mid-size businesses seeking predictable costs with room for savings.

What Is a Fully-Insured Plan?

A fully-insured plan is the traditional model where employers pay a fixed premium to an insurance carrier, which then assumes all claims risk.

How It Works

• The carrier handles claims, compliance, and reporting.
• Employers pay a consistent premium regardless of actual claims activity.
• Renewal rates are adjusted annually based on utilization.

Pros

• Minimal financial risk for the employer.
• Simple administration and compliance handled by the insurer.
• Predictable monthly budgeting.

Cons

• Less flexibility in plan design.
• Employers don’t benefit from years with lower claims.
• Premium increases can be unpredictable year-to-year.
  

Best For:

Smaller businesses or those seeking simplicity and minimal risk exposure.

How to Choose the Right Health Plan for Your Organization

When evaluating your options, consider these strategic factors:

• Risk Tolerance: Can your organization handle potential claims volatility?
• Cash Flow: Do you have consistent revenue to manage variable claim costs?
• Employee Demographics: Age, family size, and health history can influence plan performance.
• Data Insights: Access to claims data allows proactive cost control and better wellness strategy alignment.
• Compliance Complexity: Ensure your internal team or TPA can handle reporting, ERISA requirements, and ACA mandates.

Evergreen’s experts often help HR teams model different funding scenarios to forecast costs and optimize employee coverage.

Common Misconceptions

“Self-funded plans are only for large corporations.”
Not anymore — with stop-loss coverage and TPA support, even mid-sized companies can manage them effectively.

“Level-funded plans are just rebranded fully-insured plans.”
False — they combine fixed monthly costs with the opportunity to benefit from favorable claim years.

“Fully-insured plans are always the safest choice.”
They minimize risk but often lead to higher long-term costs and less transparency.

FAQs

What are the main differences between self-funded, level-funded, and fully-insured plans?

The difference is who carries the financial risk: self-funded = employer, level-funded = shared, fully-insured = carrier.

Can small businesses offer self-funded or level-funded plans?

Yes, many insurers now offer level-funded options for groups as small as 25 employees.

Are level-funded plans compliant with ACA regulations?

Yes. These plans must meet ACA and ERISA standards just like fully-insured ones.

How do refunds work in level-funded plans?

If your claims cost less than expected, you may receive a portion of the surplus at the end of the plan year.

Is stop-loss insurance required for self-funded plans?

It’s not mandatory but highly recommended to protect against catastrophic claims.
