Large Deductible vs. Guaranteed Cost Workers' Comp for PA Employers

For larger PA employers, large deductible workers' comp programs offer the potential for significant premium savings — in exchange for retaining the first $100,000, $250,000, or even $500,000 of each claim. This creates a powerful incentive for loss control but requires careful financial planning.

Large Deductible vs. Guaranteed Cost

Large Deductible

Large Deductible Program

The employer pays all claim costs up to a per-occurrence deductible (often $100K–$500K). The insurer pays claims initially and then bills the employer for costs within the deductible. The premium is significantly reduced because the carrier retains less risk.

Pros

Significantly reduced premium (carrier retains less risk)
Direct financial incentive for loss prevention and claims management
Savings can be substantial for low-loss employers
Employer retains control over claim outcomes within the deductible

Cons

Significant financial exposure for each claim within deductible
Requires collateral (letters of credit or cash) held by carrier
Complex cash flow — claims billings arrive throughout the year
Requires sophisticated claims management capability
Minimum account size typically $250K+ annual premium

Guaranteed Cost

Guaranteed Cost Policy

Standard workers' comp structure where the carrier retains all risk above the policy deductible (typically $0–$1,000 small policy deductibles). Premium is fully loaded at inception.

Pros

No per-claim financial exposure above small deductible
No collateral requirement
Predictable total cost
No complex cash flow from claim billings
Appropriate for any size employer

Cons

Higher premium because carrier bears all retained risk
Less direct financial incentive for claims management

Large Deductible vs. Guaranteed Cost — Feature Comparison

Feature	Large Deductible	Guaranteed Cost
Per-claim retention	$100K–$500K+	$0–$1,000
Premium level	Significantly lower	Standard rate
Collateral required	Yes (LC or cash)	No
Claims cash flow	Ongoing billings	None beyond premium
Loss control incentive	Direct (every dollar matters)	Indirect (EMR only)
Minimum account size	~$250K+ annual premium	Any size
Financial sophistication needed	High	Low

Bottom Line

Large deductible programs are appropriate for larger PA employers — typically $250K+ annual premium — who have strong safety cultures, sophisticated claims management, and the financial capacity to fund the deductible. The premium savings can be 30–50% compared to guaranteed cost, but the employer must be prepared to fund significant claim costs within the deductible layer.

Frequently Asked Questions

How does a large deductible affect my experience modifier in PA?

Losses within the large deductible layer are still reported to the PCRB and included in your EMR calculation. A large deductible does not reduce your EMR — it only reduces the premium you pay for the non-deductible portion of coverage. Your EMR incentive to control losses is actually stronger with a large deductible because you personally pay for every dollar of claims within the deductible.

How much collateral do large deductible programs require?

Collateral requirements vary by carrier and are based on the expected claim volume within the deductible. Typical collateral is 50–100% of the expected annual deductible obligation — often a letter of credit from a bank. This collateral ties up capital but is released as claims in the deductible layer are paid and closed.
