Methodology

How The Rates Guy compares rates.

Transparent rules. No bias. Editorial only. Below is the exact framework that produces every starting rate, table, and ranking on this site.

Step 01

Where the rates come from

We pull fresh quotes from 30+ California carriers every week using standardized driver profiles: good driver, young driver, SR-22 filer, DUI filer, and non-owner. Each rate is cross-checked against the carrier's current public California Department of Insurance rate filing before it is published.

Step 02

What we publish

Each city guide publishes a rate range, not a single number. The range reflects the spread between the lowest and highest verified monthly rate for a comparable driver profile in that city. When a carrier writes only in some ZIPs of a city, we say so.

Step 03

What we never do

We never invent a rate, a carrier, or a filing ID.

We never claim a credit score affects California auto rates. California Prop 103 prohibits credit-based auto rating.

We never bind policies on this site. The Rates Guy is editorial.

We never accept payment to move a carrier higher in a list.

Step 04

How city pages get written

Each city page is written from a per-city data block: real DMV address, real local traffic and theft stats from public sources (CHP SWITRS, NICB, U.S. Census ACS), real ZIP codes, real court information. The page generator rejects any sentence that could apply to a different California city without modification.

Step 05

Update cadence

City guides are reviewed quarterly. Rate snapshots are refreshed monthly. The page footer always shows the last updated date.

Step 06
