When to Drop Full Coverage (The 10× Rule, Explained)

The 10× rule in plain English

If your car's actual cash value (ACV) is less than 10× what you're paying annually for comprehensive + collision, drop those coverages and keep only liability. Example: car worth $5,000, you're paying $600/year for comp + collision → drop them. Car worth $14,000, paying $900/year → keep them.

How to find your real ACV

Run your VIN through KBB Private Party + Edmunds True Market Value, then average. Don't use the dealer trade-in value (it's deliberately low). Most insurers will only pay ACV minus deductible after a total loss — never the replacement cost.

The hidden risk: rolling coverage

If you finance the car, the lender requires full coverage and will force-place it (at predatory rates, ~3× standard) if you drop it. Only drop comp + collision after the loan is paid off OR your equity exceeds the typical total-loss payout buffer.

Real-world example

2014 Honda Civic worth $7,400. Full-coverage premium: $920/year ($340 of which is comp + collision). Liability-only would be $580/year. Savings: $340/year. Total loss replacement cost (after deductible): $6,400. Break-even: ~19 years. The math overwhelmingly favors dropping to liability.

Frequently asked questions

What's the difference between collision and comprehensive?

Collision covers damage from hitting another vehicle or object. Comprehensive covers everything else — theft, vandalism, weather, animal strikes. They're usually priced separately on your declarations page.

Can I drop full coverage if I'm still leasing?

No. Every lease contract requires full coverage with specific limits (typically 100/300/100 + $500 deductible) for the entire lease term.
