California does not post a single statewide cancellation fee for auto policies. What drivers usually see is cancellation math: unused premium coming back, earned premium staying with the old carrier, or an account charge that was already owed. Insurance Code Section 481 is the refund rule to keep open when the carrier explains the final number.California Legislative InformationCalifornia Department of InsuranceNAIC
The wording gets messy fast. You say fee. The carrier may say short-rate, pro-rata, earned premium, unearned premium, billing balance, returned-payment charge, or policy fee. Those are not all the same thing. Some are refund methods, and some are ordinary charges that would have been due even if you waited for renewal.California Legislative InformationCalifornia Department of InsuranceNAIC
Our desk treats the question like a price check, not a debate over labels. If the new policy is cheaper on the same driver, vehicle, ZIP, limits, deductible, mileage, and start date, then the old-policy calculation is cleanup. If the new quote only wins because coverage got cut, the fee answer is not the real problem.California Legislative InformationCalifornia Department of InsuranceNAIC
Here is the order we use with California shoppers: match the replacement quote against the current declarations page, bind the replacement, save proof, cancel with a written effective date, then ask the old carrier for every line of the calculation. Boring order. Better outcome.California Legislative InformationCalifornia Department of InsuranceNAIC
