Why Does My Car Insurance Premium Change Every Year?

Auto Insurance

car insurance premium changes every year

Your driving hasn't changed, but your bill did. That's because insurers don't set a rate once and leave it alone. Every renewal, they re-price your risk using a mix of factors that can shift year to year, and in California, state law is specific about which factors matter most.

California Law Puts Three Factors Above All Else

Under California Insurance Code Section 1861.02, insurers must weigh three factors above everything else, in this order of importance: your driving safety record, how many miles you drive annually, and how many years of driving experience you have. Insurers can layer on other approved factors after that, but by law, those three come first for every driver in the state.

What Else Can Move Your Rate

Beyond those three, a renewal price can shift because of your vehicle's year, make, and model, how you use the car (commuting daily versus occasional errands), where you're garaging it, the coverage limits and deductible you've chosen,how many drivers and vehicles are on the policy, and the individual carrier's own underwriting guidelines. None of these require you to have done anything differently. A carrier adjusting its overall pricing, or reassessing risk in your area, can change your number even in a year where nothing about your driving changed at all.

One Thing California Won't Hold Against You: Your Credit

Whatever else is behind a rate increase, it isn't your credit. California is one of the states that doesn't allow insureres to use credit-based scores or credit history to set auto insurance rates. If your premium went up, the reason lives somewhere else, not your credit report. 

A Claim or Ticket Can Follow You for a While

Accidents and moving violations don't just affect the renewal right after they happen. Insurers can weigh them for a period of time afterward, which is one reason a rate can stay elevated even after you've since been driving clean. If you're not sure whether something is still factoring into your premium, it's worth asking your agent directly rather than guessing.

The Good Driver Discount Can Push Back

If you've held a license for at least three years and have one or fewer points on your record, California requires that your rate as a Good Driver be at least 20 percent lower than what a non-Good Driver would pay for the same coverage. It's one of the few places state law works directly in your favor, and it's worth confirming you're actually receiving it.

Keeping Your Rate as Affordable as Possible

A rising renewal isn't something you just have to accept. Reviewing your coverage limits and deductible, asking about available discounts, and comparing how your current carrier prices you against others can all make a real difference, especially since pricing varies by carrier even for the same driver and the same car.

Frequently Asked Questions (FAQs)

  1. Why did my car insurance go up if I didn't file a claim?

    Rates can change due to factors beyond claims, including your carrier's overall pricing adjustments, changes in your coverage limits or deductible, and the vehicle, mileage, and location factors insurers reassess at each renewal.

  2. What are the three main factors California insurers must use to set my rate?

    By law, driving safety record, annual mileage, and years of driving experience come first, in that order of importance, before any other approved rating factor.

  3. Does my credit score affect my car insurance rate in California?

    No. California doesn't allow insurers to use credit-based scores or credit history to set auto insurance rates.

  4. What is the Good Driver Discount?

    Drivers with at least three years of licensed experience and one or fewer points must be offered a rate at least 20 percent lower than a non-Good Driver rate for the same coverage.
