Based on 7,116 six-month personal-auto policy terms written over the past 12 months, the statewide average premium in our California book is $766 per 6-month term (about $128/month) — down 8.8% from $840 the year prior. Median is $558. Below is the full city-by-city breakdown, the drivers behind the shift, and what it means for what you'll actually pay.
This index is published quarterly by Via Rapida Services, a licensed California independent insurance brokerage (CA Insurance License #6003045). The figures below are aggregated from anonymized policy terms in our own book — real premiums paid by real California drivers, not modeled estimates or industry survey data. The methodology is at the bottom of this page.
The gap between average ($766) and median ($558) is meaningful: it tells you that a subset of higher-risk or higher-value-vehicle drivers pulls the average up significantly. The typical California driver in our book is paying closer to $558 for six months — under $100 a month — not the $766 headline figure.
The table below shows average and median 6-month personal-auto premiums by city, drawn from the same 7,116-term dataset. All figures are per 6-month policy term.
| City | Avg 6-Month Premium | Median 6-Month Premium | Avg Monthly Equiv. |
|---|---|---|---|
| Stockton | $636 | $400 | ~$106/mo |
| Lodi | $654 | $342 | ~$109/mo |
| San Rafael | $772 | $605 | ~$129/mo |
| Novato | $838 | $619 | ~$140/mo |
| San Jose | $869 | $666 | ~$145/mo |
| California (statewide) | $766 | $558 | ~$128/mo |
A few things stand out in this data:
California auto insurance rates had a historically sharp run-up in 2022–2024. After years of rate suppression under Proposition 103's prior-approval framework, inflation hit — repair costs, medical costs, and used-car values all rose sharply. Carriers that had been paying out more in claims than they collected in premiums either raised rates dramatically or left the state.
Starting in late 2024, the cycle began to turn:
The net effect in our book: the average 6-month term premium fell from $840 to $766, an 8.8% decrease. Not a dramatic drop, but consistent and broad-based — we see it across city, risk segment, and vehicle type, not concentrated in any one group.
California carriers price auto insurance by zip code, using the geographic location where the vehicle is garaged as the primary rating factor. Here's what drives the spread between Lodi ($342 median) and San Jose ($666 median):
More cars per square mile means more collisions. San Jose's Highway 101, 680, and 87 corridors are among the highest-volume corridors in the state. Stockton's surface streets carry far less traffic, and Lodi even less.
Bay Area residents drive higher-value vehicles on average, which raises comprehensive and collision costs for carriers. A $45,000 SUV costs far more to repair or replace than a $12,000 older sedan — and that difference flows directly into premiums.
Auto body labor rates in the Bay Area run materially higher than in the Central Valley. The Bureau of Labor Statistics' regional wage data confirms Bay Area automotive service technicians earn significantly more than their Central Valley counterparts — and those costs land in your premium.
Certain San Jose and Marin zip codes have elevated vehicle theft rates, particularly for specific makes. This raises the comprehensive component of full-coverage premiums for drivers in those areas.
Via Rapida's Stockton book (through Insurance City) is heavily weighted toward the nonstandard market — drivers who need SR-22, have prior incidents, or are new to US insurance. That concentration of higher-risk drivers raises the Stockton average, yet the median is still the lowest in our book because most drivers are paying for basic liability coverage on older, lower-value vehicles.
This data is a useful benchmark, but your specific premium depends on factors this aggregate can't tell you:

The new 30/60/15 minimums forced a large segment of drivers who were carrying the old state minimum to upgrade their policies. For some drivers, that upgrade alone added $50–$150 to their 6-month term. It's one reason the statewide average has not fallen as steeply as competitive pressure alone would suggest — a portion of the market was effectively required to buy more coverage.
National data aggregators publish California average auto insurance figures drawn from broader carrier samples. Our data differs in two important ways:
The result: our statewide average of $766 is likely somewhat above a "typical" California driver's premium, but it is a realistic benchmark for anyone whose profile is nonstandard — which describes a large share of California's uninsured and underinsured population.

This index is based on 7,116 six-month personal-auto policy terms written over the 12-month period ending July 2026, through Via Rapida Services (CA Insurance License #6003045), an independent California brokerage.
Based on 7,116 six-month policy terms in our California brokerage book, the statewide average is $766 per 6-month term (about $128/month) and the median is $558 per term. These figures are from Q3 2026 and reflect the nonstandard-weighted market mix of an independent California brokerage. The year-over-year change is −8.8% from $840 the prior period.
In our dataset, Stockton has the lowest average at $636 per 6-month term. Lodi has the lowest median at $342. San Jose is the most expensive city in our book at $869 average / $666 median per 6-month term, driven by Bay Area vehicle values, traffic density, and higher repair labor costs.
The rate cycle that peaked in 2023–2024 — driven by inflation in repair costs, labor, and medical — began unwinding. Carriers returned to the state, competitive pressure resumed, and the CDI streamlined rate-filing reviews. In our book, the average 6-month term premium fell from $840 to $766, a decrease of 8.8% year over year.
The nonstandard market covers drivers who don't qualify for standard carrier programs: SR-22 filers, drivers with DUIs or multiple accidents, ITIN holders without an SSN, and drivers with no prior US coverage. These drivers typically pay higher premiums, which pulls our book's average above what a general statewide sample of clean-record drivers would show. If you have a clean record, your rate may be lower than these figures suggest.
As of January 1, 2025, California requires 30/60/15 liability: $30,000 per-person bodily injury, $60,000 per-accident bodily injury, and $15,000 property damage. This replaced the prior 15/30/5 minimums. Uninsured motorist coverage at the same limits is also required unless waived in writing by the policyholder per CDI guidance.
Carriers price by zip code. San Jose has higher average vehicle values, denser traffic, higher accident frequency on major corridors (101, 680, 87), higher auto body labor rates, and elevated theft rates in certain zip codes. All of those factors raise the cost of claims for carriers — and that cost is reflected in premiums for every driver in the area, regardless of their personal driving record.
