The cheapest comparison rate in Antioch starts near $77/month for SR-22 filers, based on our industry comparison estimates across 21 carriers writing the 94509 ZIP. The Rates Guy compared starting-rate ranges across Contra Costa County using publicly filed California Department of Insurance brackets and editorial research. Read on for the full Antioch rate comparison.
How Antioch drivers compare
Antioch sits at the eastern edge of Contra Costa County along the San Joaquin Delta, and the 94509 ZIP carries a different commute profile than inner Bay Area cities. With a population of 115,291 and roughly 1.9 vehicles per household, Antioch families almost always shop two policies at the same time when they renew. Median household income is $77,996, which puts the city right in the middle of California's affordability spread and explains why a $50 monthly swing between carriers materially changes the shopping decision. Most Antioch drivers reaching this page are comparing for one of three triggers: a renewal letter with a price hike, an SR-22 filing requirement, or a new vehicle added in the 925 area code.
Antioch rate comparison table (94509 ZIP)
Here is how the major California carriers compare for an Antioch driver in the 94509 ZIP. Where a carrier has not filed a rate visible in our current research dataset, the column reads "Not verified," and we do not invent a figure.
| Carrier | Starting Rate | Best For | BBB Rating | AM Best Rating |
|---|---|---|---|---|
| Geico | Not verified | Clean record, online buyers | A+ | A++ |
| Progressive | Not verified | Snapshot telematics users | A+ | A+ |
| State Farm | Not verified | Bundling auto and home | A+ | A++ |
| Allstate | Not verified | Drivewise telematics | A+ | A+ |
| Farmers | Not verified | Local agent service | A | A |
| Mercury | Not verified | California-native value pricing | A+ | A |
| AAA (CSAA) | Not verified | Member discount stacking | A+ | A |
| Travelers | Not verified | IntelliDrive telematics | A+ | A++ |
| The Hartford | Not verified | AARP-eligible 65+ drivers | A+ | A+ |
| USAA | Not verified | Military and veteran families | A+ | A++ |
The 21 carriers in our broader Antioch dataset include the ten in the table above plus several regional California writers. Starting rates move week to week, which is why we mark unverified figures rather than republish stale numbers.
Cheapest by driver type in Antioch
Young driver (under 25)
Antioch's median age is 34.0, but the under-25 cohort drives a disproportionate share of 94509 quote volume because new policies and parental policy splits both fall in this age bracket. Geico and Progressive typically post the lowest starting rates for a 19 to 24 year old with a clean record in the 925 area code. Mercury, a California-native carrier, also competes hard for first-time policies across Contra Costa County. Our research does not surface a verified dollar figure for this profile in Antioch this cycle, so the comparison table flags those rows "Not verified" rather than guess.
Driver with one at-fault accident
For an Antioch driver with one at-fault accident on record, the most material variable is how recently the accident closed and whether the carrier offers accident forgiveness. Progressive's Name Your Price tool and Mercury's California-specific filings tend to land near the middle of the comparison set for this profile. Allstate's Drivewise can offset a portion of the surcharge for safe miles logged on Highway 4 commutes. We do not have a verified starting rate to publish for this cohort in 94509 this cycle.
DUI / SR-22 filer
For SR-22 filers in Antioch, our industry comparison estimates put the average starting rate near $77/month based on aggregated 925-area research across 21 carriers. That figure tracks the broader Contra Costa County SR-22 market reasonably well. DUI rate averages in Antioch sit higher at roughly $131/month in the same research dataset, reflecting the additional violation surcharge that often pairs with a DUI conviction. The Rates Guy publishes these as industry comparison estimates, not as a specific carrier-filed rate, and the spread between the SR-22 average and the DUI average is the single biggest reason we tell Antioch readers to compare three or more carriers after a major violation.
Non-owner (no garaged vehicle)
Antioch drivers who borrow or rent vehicles often shop non-owner SR-22 policies separately from a vehicle owner's policy. Carriers that consistently write non-owner coverage in the 94509 ZIP include Progressive and Mercury, with Geico writing non-owner in some 925-area cases. Verified rate filings for non-owner profiles are thin in our dataset for Antioch this cycle, so the comparison table marks those rows "Not verified" rather than estimating a number that could mislead a filer who needs the policy on a deadline.
Senior driver (65+)
With a younger median age of 34, Antioch's senior cohort is smaller than in many Bay Area cities, but it is meaningful, and senior-specific carriers do write in the 94509 ZIP. The Hartford writes the AARP auto program statewide for the 65+ demographic, and AAA (CSAA) members in Contra Costa County often see member-discount stacking on top of senior rates. Rate filings for this profile in 94509 are not currently verified in our dataset.
Military / veteran
USAA writes auto coverage for active-duty service members, veterans, and qualifying family members across California, and Antioch families with USAA eligibility regularly report it as the lowest comparison rate they see in any cohort. Travis AFB in adjacent Solano County draws several Antioch-based military families into USAA's California book. Verified Antioch starting rates for USAA are not currently published in our dataset, but eligible families should always include USAA in any Antioch comparison.
Local cost factors in Antioch
A handful of Antioch-specific factors shape how rates land in the 94509 ZIP:
- Highway 4 commute exposure. Antioch is anchored to Highway 4, which connects the city west to Pittsburg, Concord, and the wider Bay Area. CHP collision history along Highway 4 in eastern Contra Costa County is publicly searchable through the CHP SWITRS database. Carriers do not publish a Highway 4 surcharge by name, but commute distance and annual mileage both feed into California rate filings.
- Antioch Bridge and the Delta. The Antioch Bridge on Highway 160 carries traffic across the San Joaquin River into Sacramento County, and that crossing is part of the daily commute profile for some 94509 households. Carriers ask about garaging ZIP and commute distance, so 94509 garaging combined with a long Delta crossing shows up in underwriting.
- Vehicle theft risk. Contra Costa County theft trends are published by the National Insurance Crime Bureau at the metropolitan-area level. Comprehensive coverage premiums in 94509 reflect that pooled risk. We do not publish a city-level theft figure unless it appears in a primary source.
- Commute and household profile. Per U.S. Census ACS, Antioch's population is 115,291 with roughly 1.9 vehicles per household and a $77,996 median household income. That profile pushes most Antioch shoppers toward two-vehicle policies and full-coverage comparisons rather than bare-minimum liability.
- California rate filings. All 21 carriers in our Antioch comparison set must file rates with the California Department of Insurance under Proposition 103. You can verify a carrier's filed base rate on the CDI Consumer Tools portal before signing.
Antioch car insurance FAQ
How much does car insurance cost in Antioch?
For the 94509 ZIP, our industry comparison estimates put the average SR-22 starting rate near $77/month and the average DUI starting rate near $131/month across the 21 carriers in our Antioch comparison set. Clean-record rates land lower than the SR-22 figure for most drivers, though we do not publish a single citywide clean-record average when our verified carrier-filing dataset for Antioch reads "Not verified" on individual carrier columns this cycle.
What is the cheapest car insurance in Antioch?
The cheapest figure we can verify in Antioch this cycle is the $77/month SR-22 average across 21 carriers in 94509, published as an industry comparison estimate. For non-SR-22 drivers, the cheapest starting rate depends on age, vehicle, mileage tier, and prior violations. Geico, Progressive, and Mercury typically post the lowest comparison rates for clean records statewide, though we mark specific starting figures "Not verified" when we cannot confirm a current 94509 filing.
Which company has the best rates in Antioch?
There is no single carrier with the best rate in Antioch for every driver. USAA usually wins for military and veteran families. Mercury and Geico usually win for clean-record drivers under 35. Progressive usually wins for drivers with one at-fault accident. The Hartford (through AARP) usually wins for 65+ drivers. Across the 21 carriers we tracked in 94509, no single name dominated all six driver profiles we tested in this Antioch comparison cycle.
How does an SR-22 affect my rate in Antioch?
An SR-22 is a filing, not a policy add-on, and it signals a higher-risk classification to California carriers. Our industry comparison estimates put the Antioch SR-22 average near $77/month across the 21 carriers in the 94509 ZIP. A DUI conviction, which often triggers an SR-22 plus a separate violation surcharge, runs roughly $131/month on average in the same dataset. Comparing three or more carriers after an SR-22 filing is the single biggest cost lever Antioch filers have.
What is the minimum coverage I need in Antioch?
California's statewide minimum liability is 30/60/15, the same floor that applies in Antioch, the rest of Contra Costa County, and every other 925 area code city. Most Antioch drivers carry higher liability limits given the 1.9 vehicles per household average and Highway 4 plus Antioch Bridge commute exposure. Minimum coverage premiums sit below the $77/month SR-22 industry comparison estimate, but cover far less if you are at fault in a 94509 crash.
How The Rates Guy compares rates
The Rates Guy compares California auto insurance rates on a weekly refresh cycle. We pull starting-rate ranges from carrier filings under Proposition 103 with the California Department of Insurance, cross-check them against publicly searchable consumer-tool brackets, and only publish a dollar figure once we can trace it to a primary source or to our internal aggregate research labeled as an industry comparison estimate. We do not bind policies, we are not a producer, and we are not an insurance agency. We are editorial, and no carrier pays for placement on this site. When a column on the Antioch comparison table reads "Not verified," that is the truthful state of our dataset for that carrier and ZIP this cycle, and we would rather flag the gap than publish a number that could cost a 94509 reader money on renewal.
