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.

  • $500,000

  • $41,667

    Monthly accommodation

  • $75,000

    Employer pays on that claimant

  • $75,000

    Stop-loss pays on that claimant

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.

Example
$75,000 specific deductible
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.

Example
$500,000 aggregate (125% of $400K expected)
Total claims reach $600,000
Employer pays: $500,000
Stop-loss pays: $100,000

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.
