TLDR
  • California averages around $3,668/year — pricing is driven almost entirely by the major metro markets
  • Rates rose +6.1% in 2026, continuing a multi-year climb after carriers pulled back and then returned
  • Wawanesa is consistently the highest-rated carrier in CA; State Farm recently re-entered new business here
  • California prohibits using credit scores in underwriting — rates are based more on driving record and miles driven
  • Rate spreads are enormous — the cheapest carrier can be 60%+ below the most expensive for the same profile

California drivers are facing a projected 6.1% rate increase in 2026 — one of the five steepest projected increases nationally. The state average of $3,668 per year for full coverage is already well above the national baseline, and the trend is moving in the wrong direction.

California's insurance market is structurally different from most states. Proposition 103, passed in 1988, requires prior approval for rate changes and prohibits carriers from using credit scores in pricing. The result: carriers can't adjust rates as quickly as costs change, which creates cycles of underpricing followed by large correction increases when regulators approve catch-up filings.

Why 2026 increases are hitting California hard

Wildfire exposure is the dominant factor. As climate-driven fire risk has expanded geographically, auto carriers have had to recalibrate comprehensive coverage pricing for large parts of the state. High repair costs in LA and San Francisco metros — labor rates, parts prices, EV repair complexity — are a secondary driver. And California's litigation environment keeps bodily injury claims elevated relative to comparable states.

Some carriers have restricted their California appetite or paused new business in certain territories. That reduces competition, which over time pushes prices up. Shopping aggressively at renewal is more important in California than in most states precisely because the market is less competitive.

California rule: Carriers cannot use credit scores to set rates in California. This means your credit history won't help or hurt you here — but your driving record, vehicle, and ZIP code carry even more weight than in other states.

What are California's minimum auto insurance requirements?
As of January 1, 2025, California increased its mandatory minimums to 30/60/15: $30,000 per person for bodily injury, $60,000 per accident, and $15,000 for property damage. The previous limits of 15/30/5 — unchanged since 1967 — were widely considered inadequate. California is a tort (at-fault) state, and all rate changes by insurers must be approved by the state Department of Insurance under Proposition 103.

Why is car insurance so expensive in California?
California consistently ranks among the most expensive states for auto insurance due to a combination of high vehicle repair costs, dense population, and a litigation environment that drives up bodily injury claims. Proposition 103 requires state approval before insurers can raise rates, which has historically slowed carriers from keeping pace with rising claims costs — leading some major insurers to limit new business or exit certain markets. Wildfire risk also adds to comprehensive insurance costs in many parts of the state.

Can California insurers use my credit score to set my rates?
No — California is one of a small number of states that prohibits the use of credit-based insurance scores in auto insurance pricing. Insurers in California must base premiums primarily on your driving record, miles driven, and years of driving experience. This means a driver with poor credit but a clean driving record pays the same rate as someone with excellent credit and the same record.
