California Auto Insurance Cost Calculator
Estimate estimated car insurance premiums based on California averages
California Calculator
Find the right coverage
Updated for 2025 with real California rates, brackets, and regulations
California's Proposition 103 (1988) makes car insurance uniquely regulated: insurers CANNOT use credit scores, education level, or occupation to set rates. Instead, rates must be primarily based on driving record, annual miles driven, and years of experience. Despite this consumer protection, CA auto insurance averages $2,000-$2,500/year — well above the national average — driven by high vehicle values, traffic density, and repair costs. LA and SF are among the most expensive zip codes in the nation. This calculator estimates your premium based on Prop 103-compliant factors.

Frequently Asked Questions
How does Proposition 103 affect my car insurance?
Prop 103 prohibits insurers from using credit score, education level, occupation, or gender to set rates. The three primary rating factors must be: driving safety record, annual miles driven, and years of driving experience.
What is California's minimum auto insurance?
CA minimums are: $15,000 bodily injury per person, $30,000 per accident, $5,000 property damage (15/30/5). These are among the lowest minimums in the US and are widely considered inadequate for CA's high costs.
Why is car insurance so expensive in California?
High vehicle values, dense urban traffic, expensive repair/medical costs, high theft rates (especially in LA/SF), and large uninsured motorist population (~15%). Despite Prop 103 consumer protections, costs remain well above national average.
Which California city has the most expensive car insurance?
Los Angeles has the highest average premiums, followed by Oakland, San Francisco, and parts of the Central Valley. Zip codes in South LA and parts of Oakland can exceed $3,500/year for standard coverage.
Can I get a discount for low mileage in California?
Yes. Under Prop 103, annual mileage is a mandatory rating factor. Drivers under 7,500 miles/year typically receive 5-15% discounts. California Low Cost Auto Insurance Program also offers reduced rates for low-income drivers.
