Self-Funded Risk Management
Stop-loss insurance calculator
Determine optimal stop-loss coverage for self-funded health plans with Planlined's free calculator. Analyze specific and aggregate deductible options to balance premium costs with risk protection.
Calculator
Set the attachment points and see the exposure.
Specific stop-loss caps one claimant. Aggregate caps the year. Both matter, and they answer different questions.

How this is calculated
The aggregate attachment point is expected claims at the corridor you chose (125%), which leaves $100,000 of claims above expectation that the employer carries before aggregate stop-loss responds. Monthly accommodation is that attachment point spread over twelve months, which is how a carrier funds reimbursement through the year rather than at the end of it.
On a single claimant, the employer pays up to the specific deductible of $75,000 and stop-loss pays the excess.
Excluded: lasers on known claimants, terminal liability, run-in and run-out, and the contract basis (12/12 against 12/15), each of which moves real exposure. An estimate for planning, computed in your browser.
What is stop-loss insurance?
Stop-loss insurance protects self-funded employers from catastrophic claims that could exceed their financial capacity. It's essential risk management for any organization paying claims directly rather than through fully-insured premiums.
Specific stop-loss
Individual claim protection
Protects against high-cost individual claimants. When a single person's claims exceed the specific deductible, stop-loss reimburses the excess.
Employee has $150,000 in claims
Employer pays: $75,000
Stop-loss pays: $75,000
Aggregate stop-loss
Total claims protection
Caps total annual claim liability. When combined claims exceed the aggregate attachment point, stop-loss pays the excess.
Total claims reach $600,000
Employer pays: $500,000
Stop-loss pays: $100,000
Specific deductible options
| Deductible Level | Premium Impact | Employer Risk | Best For |
|---|---|---|---|
| $25,000 | Highest | Lowest | Very risk-averse, small groups |
| $50,000 | High | Low | Small groups (25-75 employees) |
| $75,000 | Moderate-High | Low-Moderate | Mid-size groups (50-150) |
| $100,000 | Moderate | Moderate | Common choice for 100+ groups |
| $150,000 | Low-Moderate | Moderate-High | Larger, healthy groups |
| $200,000+ | Lowest | Highest | Large groups with reserves |
Aggregate corridor options
| Corridor % | Employer Risk | Premium Impact | Notes |
|---|---|---|---|
| 120% | Lowest | Highest | Maximum protection, minimum risk |
| 125% | Low | Moderate | Most common corridor level |
| 130% | Moderate | Low | Balance of cost and protection |
| 135% | Higher | Lowest | Higher risk tolerance required |
Key stop-loss considerations
Lasering
Carriers may "laser" (increase deductible for) specific high-risk individuals. Review laser provisions carefully and negotiate alternatives.
No new laser guarantee
Some carriers offer protection against new lasers at renewal. This provides cost predictability for known conditions.
Terminal liability
Coverage for claims incurred during the policy year but paid after termination. Critical for plan transitions.
Monthly accommodation
How the aggregate attachment is spread monthly. 1/12 accommodation provides more protection early in the year.
Model self-funded scenarios
Planlined helps you compare self-funded, level-funded, and fully-insured options with accurate cost projections.
Frequently asked questions
What is the typical specific stop-loss deductible?
Specific deductibles typically range from $25,000 to $250,000+ depending on group size and risk tolerance. Smaller groups often choose $40,000-$75,000, while larger groups may select $100,000-$200,000 to reduce premiums.
How is aggregate stop-loss attachment calculated?
Aggregate attachment is typically 125% of expected claims. For example, if expected claims are $400,000, the aggregate attachment would be $500,000. Corridors range from 120% to 135% depending on the carrier and group risk profile.
Should I buy specific, aggregate, or both?
Most self-funded plans need both. Specific protects against individual catastrophic claims, while aggregate caps total annual exposure. Smaller groups especially need both layers of protection.
