How much does comprehensive coverage add to liability-only?
Comprehensive coverage adds $1,200 to $2,800 per year to liability-only policies for most drivers. This upgrade protects your car from theft, weather damage, and other non-collision events. Liability-only covers damage you cause to others. It leaves your vehicle unprotected.
Here's what you need to know:
- National average: Liability costs $820 per year. Full coverage (liability + comprehensive + collision) runs $2,697 per year. That's $1,877 extra (Source: Bankrate Insurance Analysis, 2026).
- In Texas (ZIP 78705): Drivers pay $1,200-$1,800 for liability. Adding comprehensive boosts it to $2,700-$4,300. Extra cost: $1,500-$2,500 (Source: Sidekick owner data, N=1,200, February 2026).
- "Upgrading to comprehensive saves owners an average of $8,400 in out-of-pocket repair costs after hail storms," says the Sidekick Research Team, based on 950 Texas claims.

Why Add Comprehensive?
Texas weather hits hard. Hail storms in Austin average $4,200 per claim. Comprehensive covers that after your deductible. Without it, you pay full price.
Liability-only works if your car is old and worth under $4,000. Most drivers need more protection. Lenders require it for financed cars.
