When to Drop Full Coverage
The 10% rule and its limits, how to value your car, the comprehensive-only option, and the steps to drop collision without creating gaps.

Answer in brief
A common guideline says drop collision and comprehensive when the annual premium for them exceeds about 10% of the car's value. It is a starting point, not a rule—also weigh your savings, the car's role, and theft or weather risk. Many drivers drop collision first and keep comprehensive, which is cheap. Never drop coverage on a financed car. When you do drop it, raise liability and uninsured motorist with part of the savings.
Worked example
Car worth $5,000, collision deductible $1,000. The most collision can ever pay is $4,000. If collision costs $500 a year, you are paying 12.5% of the maximum payout annually—borderline. If comprehensive costs $120, keep it: hail or theft are real risks and the premium is small.
Steps
- 1
Value the car
Use two online valuation tools at private-party condition.
- 2
Price the coverage
Ask the insurer what collision and comprehensive each cost.
- 3
Decide separately
Collision and comprehensive are separate decisions.
- 4
Confirm no lien
Dropping coverage on a financed car breaches the loan.
- 5
Redirect savings
Raise liability and uninsured motorist limits.
