Umbrella Outflow = max(0, Total Claim Liability - Primary Policy Limit)

Step-by-Step Mathematical Derivation

Primary Policy Layer Exhaustion

Primary Auto Liability covers the first $500,000.00, exhausting 100% of the primary policy.

Umbrella Attachment Point

Excess damages = $1,650,000 - $500,000 = $1,150,000.00 attaching directly to the umbrella policy.

Remaining Umbrella Capacity

Remaining Umbrella = $2,000,000 - $1,150,000 = $850,000.00.

Defendant Wealth Shield

Because total damages ($1.65M) did not exceed combined limits ($2.50M), personal savings and home equity are 100% shielded from attachment.

Frequently Asked Questions

What happens if a claim exceeds both primary and umbrella limits? +

If damages exceed total policy limits, the plaintiff can obtain a deficiency judgment against the at-fault defendant, leading to wage garnishment, bank account levies, and liens on real property.

How much does a $1 million personal umbrella policy typically cost? +

Personal umbrella policies are surprisingly inexpensive, typically costing between $150 and $300 per year for $1 million in coverage, provided you maintain required underlying auto/home limits ($300k/$500k).
