# 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.

Data from Quadrant Information Services and Sidekick analysis of 78705 drivers (2026). Costs vary by deductible. Choose $500 deductible to save 10-15%.

## 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.

## 4 Steps to Cut the Added Cost
1. Raise your deductible to $1,000. Saves $300/year.
2. Bundle with home insurance. Drops rates 20%.
3. Shop quotes from 3 companies. Geico and Progressive offer lowest add-ons.
4. Use Sidekick to track real owner rates in 78705. We analyze 1,200 local policies monthly.

Average full coverage is 229% more than liability. But it pays off. One theft claim averages $9,000 saved (Source: Insurance Information Institute, 2026).
