The honest answer: an at-fault accident raises full-coverage rates about 30% to 50% nationally, with most published rate analyses landing near 40%. On a $150-a-month policy that's roughly $63 more per month, or $756 a year — and it keeps coming for three to five years. The surcharge, not the repair, is usually the expensive part of a fender bender. Here's what drives the number, how long it lasts, and when paying out of pocket wins.
Insurers don't publish one national surcharge, but rate filings and industry analyses (The Zebra, Bankrate, and carrier data) cluster in a consistent range. Property-damage accidents land near the middle; injury claims and repeat incidents push toward the top:
| Incident | Typical increase | On a $150/mo policy |
|---|---|---|
| Accident, not at fault | 0% – 12% | $150 – $168/mo |
| At-fault accident (property damage) | 30% – 50% | $195 – $225/mo |
| At-fault accident (injury claim) | 45% – 65% | $218 – $248/mo |
| Second at-fault accident | often 60% – 90% | $240 – $285/mo |
| DUI / DWI (first offense) | 65% – 85% | $248 – $278/mo |
Notice how much less a not-at-fault accident costs you. Some states, including California, prohibit surcharges for accidents you didn't cause. If your premium jumps double digits after a crash that wasn't your fault, treat it as an invitation to shop.

Car Insurance Rate Increase Calculator →Three to five years, with three the industry default. Two clocks run at once: the surcharge window your insurer applies (usually 3 years) and the record window — accidents stay on your CLUE claims report for five to seven years, and a DUI can stay on your motor vehicle record for five to ten depending on the state.
The pricing effect isn't flat, either. Many carriers step the surcharge down at each clean renewal, so year three of a 42% surcharge might look more like 20% before it drops off entirely. The practical takeaway: put a calendar reminder on each renewal. Loyalty after an accident is rarely rewarded — insurers count on you not re-shopping while the surcharge decays.
Do the arithmetic before you call your agent. Say you backed into a parked car and the repair estimate is $1,800 with a $500 deductible. Filing nets you $1,300 from the insurer — but a 42% surcharge on a $150 monthly policy costs about $2,268 over three years. Paying out of pocket saves you roughly $968 and keeps the claim off your CLUE report.
The out-of-pocket logic collapses the moment another driver, a passenger, or any injury is involved. Liability claims — the kind where someone else's medical bills and lost wages enter the picture — routinely dwarf any surcharge, and state law often requires you to report them. Never hide an accident from your insurer to avoid a surcharge; an unreported claim that resurfaces can get coverage denied when you need it most.
Nationally, full-coverage rates rise 30% to 50% after an at-fault accident, with most industry analyses near 40%. On a $150-a-month policy, a 42% surcharge is $213 a month — $63 more per month and $756 more per year. Injury claims run higher, often 45% to 65%.
Three to five years at most insurers, with three the most common. The accident stays on your CLUE claims report five to seven years, but the pricing impact steps down each clean-renewal year.
It can, but usually much less — 0% to 12%. California and a few other states bar surcharges for not-at-fault accidents. A large increase after a not-at-fault crash is a signal to shop elsewhere.
Often, yes, for minor single-car damage. A 42% surcharge on a $150 monthly policy costs about $2,268 over three years — more than most fender-bender repairs. File the claim whenever another driver, a passenger, or injuries are involved; those costs dwarf the surcharge.
If you bought it (or earned it through tenure) before the accident, yes — the first at-fault claim is usually waived. It cannot be added after the accident, and it typically doesn't transfer if you switch carriers.
