How to Use the Car Insurance Calculator

- 2
Enter your vehicle value and age and select your coverage options. Comprehensive and collision coverage protect your vehicle but may not be worth the cost on older low-value cars. A general rule is to drop comprehensive and collision when the annual premium exceeds 10% of the vehicle value.

Frequently Asked Questions
What factors affect car insurance premiums the most?
The five biggest factors are your driving record — a DUI can double your premium, your age — drivers under 25 pay up to 2.5 times more than middle-aged drivers, your credit score — poor credit can increase premiums by 50% in most states, your location — urban ZIP codes with high theft and accident rates pay more, and your coverage selections. Shopping multiple insurers is also critical since the same driver can receive quotes varying by 50% or more from different companies.
When should I drop comprehensive and collision coverage?
A common rule of thumb is to drop comprehensive and collision coverage when the combined annual premium for those coverages exceeds 10% of your vehicle value. For example if your car is worth $5,000 and comprehensive plus collision costs $600 per year that is 12% of the vehicle value — likely not worth it. You should also consider dropping these coverages if you could comfortably replace the vehicle out of pocket without a large financial burden.
How does my credit score affect car insurance?
In most US states insurers use a credit-based insurance score to help set premiums. Drivers with poor credit pay on average 50% more than drivers with good credit for the same coverage. California Hawaii and Massachusetts prohibit the use of credit scores in auto insurance pricing. Improving your credit score is one of the most impactful ways to reduce your car insurance premium over time.
What do the liability coverage numbers mean?
Liability coverage is expressed as three numbers such as 100/300/100. The first number is the maximum payout per person for bodily injury in thousands of dollars. The second is the maximum per accident. The third is the maximum for property damage. So 100/300/100 means up to $100,000 per person, $300,000 per accident, and $100,000 for property damage. State minimums are typically far lower and many financial advisors recommend at least 100/300/100 to protect your assets.
How much can I save by shopping around for car insurance?
Studies consistently show that drivers who compare at least 3 insurance quotes save an average of 15% to 30% compared to staying with their current insurer. Insurers use different rating algorithms so the same driver can receive vastly different quotes. Most insurers also offer discounts for bundling home and auto insurance, safe driver programs, good student discounts, and low mileage discounts.
How does raising my deductible affect my annual premium?
Raising your deductible (e.g., from $250 to $1,000 or $2,000) lowers the insurer's potential claim payout risk. This directly reduces your monthly and annual premium costs, as shown in the calculator's Deductible Comparison table. Ensure you have the deductible amount saved in an emergency fund in case you need to file a claim.
