The Insurance Information Institute suggests that you take the amount you'd pay in one year for comprehensive and collision coverage, and multiply that number by 10. Is your car worth less than that number? Then comprehensive and collision coverage might not be a cost-effective option for you.

When you purchase comprehensive coverage, you will select a set deductible, which is the amount you pay out of pocket toward a covered claim. Let's say you choose a $500 deductible, and your car is later damaged by hail in a covered claim. If it costs $1,500 to repair your car, you would pay your $500 deductible, and your insurance would pay the remaining $1,000.
