What Affects Your Car Insurance Rate? 10 Factors Explained

The ten factors insurers use to price car insurance, from ZIP code and driving record to credit, vehicle and coverage choices, and which ones you can change.

Quick answer

Car insurance rates are based on your ZIP code, driving record, age and experience, vehicle, annual mileage, coverage and deductibles, credit-based insurance score (where allowed), claims history, gaps in coverage, and discounts. Your record, coverage choices, mileage and credit are the factors you can most directly improve.

ZIP code

Where your car is garaged drives claim frequency, theft rates, weather exposure and repair costs. Miami, Atlanta and Charlotte cost more than smaller towns in the same states.

Driving record

Tickets, at-fault accidents and DUIs are the biggest controllable factor. North Carolina's SDIP and South Carolina's points system turn each violation into a defined surcharge.

Age and experience

Teen and young-adult drivers pay the most. Rates typically fall through your 20s and level off in your 30s.

Vehicle

Repair cost, safety ratings, theft rates and horsepower all matter. A reliable mid-size sedan usually costs less to insure than a luxury SUV or sports car.

Annual mileage and use

Long commutes and business use add risk. Working from home can lower your rate if you report it.

Coverage and deductibles

Higher liability limits and lower deductibles cost more. Matching both to your real needs is where most savings hide.

Credit-based insurance score

All five states we serve allow it. Improving credit tends to improve rates over time.

Claims history

At-fault claims typically affect your rate for three to five years. Small claims close to your deductible are sometimes not worth filing.

Continuous coverage

A lapse signals risk to insurers. Keep a policy active even if you're between cars, with a non-owner policy if needed.

Discounts

Bundling, good student, defensive driving, military, federal employee, multi-car and payment discounts can offset many of the factors above.

Frequently asked questions

Why did my car insurance go up when nothing changed?

Statewide rate increases, rising repair and medical costs, and changes in your area's claim trends can raise rates even with a clean record. North Carolina's 2025 minimum-coverage increase is one example.

Does the color of my car affect insurance?

No. Make, model, year, trim and safety features matter; color does not.
