What Affects Your Car Insurance Premium

Person reviewing bills and ways to lower their car insurance premium

Your premium is what you pay (monthly, every six months, or annually) for coverage. Insurers calculate it from dozens of factors, but a handful do the heavy lifting.

Biggest factors

  • Driving record: at-fault accidents, speeding tickets, and DUIs raise rates significantly. A clean record is the single best way to keep rates low.
  • Age and experience: drivers under 25 pay far more. Rates typically drop sharply around age 25 and again at 30.
  • Location: urban ZIP codes with more theft, accidents, and traffic cost more than rural areas.
  • Vehicle: expensive cars, sports cars, and frequently stolen models cost more to insure. Safety features can lower the premium.
  • Credit-based insurance score: in most states, a higher credit score means a lower premium.
  • Coverage limits and deductibles: higher limits and lower deductibles raise the premium.
  • Mileage: drivers who commute long distances pay more.
  • Marital status: married drivers often get slightly lower rates.

How to lower your premium

  1. Shop around - quotes can vary 30–50% between insurers for the same coverage.
  2. Bundle policies - combining car + renters or homeowners can save 10–25%.
  3. Raise your deductible - going from $500 to $1,000 typically cuts the premium 10–15%.
  4. Ask about discounts - good driver, safe vehicle, low mileage, paperless, autopay, defensive driving course, good student.
  5. Improve your credit score - affects rates in most states.
  6. Drop unnecessary coverage - collision/comprehensive may not be worth it on an older car worth less than ~$2,000.
  7. Use telematics/usage-based programs - let the insurer track your driving for a potential discount.
