Does Filing a Claim Raise Your Rate, Even a No-Fault One?

Most drivers assume that only an accident they caused raises their insurance. It is a reasonable assumption and, at many carriers, an incomplete one. Insurers price two related but separate things: who was at fault for a crash, and how many claims you have filed. The first drives a driving-record surcharge; the second drives a distinct prior-claims factor that can rise even when a claim was not your fault, and even when it had nothing to do with driving at all, like a theft or a hailstorm. That second lever is the one most people never see coming.

This page examines it with real filed numbers rather than rules of thumb. We read Mercury Casualty Company's Nevada personal-auto filing and pulled its Prior Claims Factor table directly, along with the filed definitions of the claim types it counts, so you can see exactly how a not-at-fault accident and a no-fault comprehensive claim move the price. Every figure here is a value we read in the filing on file with the state, not an estimate.

Even a no-fault claim raises your rate

Here is the part that surprises people. A comprehensive claim covers losses that are, by definition, not a driving mistake: theft, vandalism, fire, flooding, hail, a cracked windshield, or hitting a deer. No one is "at fault" in the way they are for a fender-bender. Yet in this filing a single comprehensive claim still raises the bodily-injury factor, to 1.049 for a smaller one and 1.089 for a larger one, and repeated comprehensive claims climb steeply from there. The same is true of a not-at-fault accident: even though it adds no driving-record points, it nudges this factor from 0.980 to 0.990.

Why would a claim you did not cause cost you? Because insurers price on claim frequency as a predictor, not only on blame. Statistically, a driver who has filed claims, of any kind, is somewhat more likely to file again than one who never has, whether the reason is where they park, how they drive, or simple bad luck that tends to repeat. The insurer is allowed to reflect that pattern in a filed factor. It feels unfair to be surcharged for a stolen catalytic converter, and consumer advocates such as the Consumer Federation of America have criticized the practice, but it is a real and filed part of how this carrier prices risk.

When it is worth filing a claim, and when it is not

Because a claim can raise your rate for years, a small claim is not always worth filing. The practical test is to weigh the payout against the likely added premium over the surcharge period. If a windshield or a minor comprehensive loss is close to your deductible, filing it can cost more in higher renewals than it returns, especially since, in this filing, even that no-fault claim moves the factor. For a large loss you could not absorb yourself, filing is what the coverage is for; for a small one near your deductible, paying out of pocket often comes out ahead.

Two practical notes. First, your claim history is not private to one insurer: most carriers report and read claims through a shared industry database (commonly the C.L.U.E. report), and you are entitled to your own copy. Second, because carriers weight claim history very differently, and some far more gently than others, comparing carriers matters most right after a claim, when the surcharge is freshest. The Insurance Information Institute covers this trade-off in its guidance on what determines your auto price.
