Cost benchmark
Car Insurance Cost After an At-Fault Accident (2026)
An at-fault accident raises your full-coverage premium about 44 percent on average per published aggregator benchmarks. For a clean-record 35-year-old whose pre-accident premium was $2,400 per year, year 1 after an at-fault totals roughly $3,450; year 2 roughly $3,100; year 3 roughly $2,700; and the surcharge ages off by year 4 in 3-year-lookback states. Total 3-year cost impact is approximately $2,500 to $3,800 above the baseline. This page is the money math; for what to DO after an accident see after-accident, and for the specific liability-pay-who-what see at-fault accident.
Year-by-year math (clean-record $2,400 baseline)
| Year | Typical surcharge | Annual premium | Delta vs baseline |
|---|---|---|---|
| Year 1 | +44% (front-loaded) | ~$3,450 | +$1,050 |
| Year 2 | +30% | ~$3,100 | +$700 |
| Year 3 | +13% | ~$2,700 | +$300 |
| Year 4+ (3-yr lookback states) | 0 | ~$2,400 | $0 |
Carrier lookback windows
- Progressive: 3 years for most at-fault incidents; 5 years for serious or injury accidents.
- Allstate: 5-year standard lookback.
- State Farm: 3 years for minor accidents; up to 5 years for serious.
- GEICO: 5 to 7 years severity-dependent.
- California: state insurance code 1861.025 caps most at-fault surcharges at 3 years.
Does switching carriers mid-surcharge save money?
Sometimes. The current carrier's surcharge is their underwriting view, not a universal rate. A competitor can price the same event more leniently, especially if your other rating factors (credit, prior insurance tenure, discounts) favor the new carrier. CLUE loss history travels with you, so the new carrier sees the accident and can surcharge it, but it typically applies a fresh clock. Expect quotes to vary by 15 to 40 percent across carriers for the same at-fault profile.
Accident forgiveness can zero the surcharge
If you had accident forgiveness on the policy at the time of the loss, your current carrier does not apply the surcharge. The accident still appears on CLUE for future carriers.
What drives the rate change: components
An after-accident premium increase is not one line item. It is a stack of carrier-filed effects that start and age off independently. Decomposing the stack is the fastest way to see which part a specific intervention (shopping, forgiveness, telematics) can actually change. Rules are carrier-filed with each state department of insurance and vary; the table below describes the mechanisms, not national rate percentages. For claim-type variation see will my insurance go up after a claim.
| Component | What it is | How long it lasts | Mitigation |
|---|---|---|---|
| Chargeable-accident surcharge | Carrier-filed rate increase applied at renewal after an at-fault accident, under the carrier's filed rating plan with the state DOI. | Carrier-filed, typically 3 to 5 years. The exact window is on your filed rating plan; California caps most at-fault surcharges at 3 years. | Accident forgiveness endorsement where offered, or shop at renewal. |
| Loss of good-driver discount | Dropping from a lower-rate tier to a higher-rate tier because a chargeable incident disqualifies the discount. | Until the discount is re-earned, typically 3 to 5 claim-free years under the carrier's filed definition. | Clean driving plus telematics enrollment in some programs; shop carriers that tier differently. |
| Deductible paid at claim | Out-of-pocket amount paid when a first-party coverage (collision or comprehensive) pays your damage. | One-time at claim. Not a recurring premium effect. | Not applicable to premium. Your deductible may be recovered via subrogation if a third party is at fault; see subrogation. |
| Possible nonstandard-market move | If the carrier declines to renew after a serious or repeat incident, re-entry is typically in the nonstandard market at higher rates. | Until continuous-coverage history and clean driving return you to the standard market. | Compare quotes before the non-renewal takes effect; a standard-market carrier placing you now is faster than clawing back from nonstandard later. |
File or pay out of pocket? A decision box
The comparison is not deductible against repair cost alone. It is deductible plus the surcharge stack above against repair cost. We do not quote fixed surcharge percentages: the number depends on your carrier's filed rating plan, your state, and your prior record. Treat the surcharge qualitatively (typically 3 to 5 years at carrier-filed rates) and shop at renewal to test it. For the structured version of this call see should I file a car insurance claim and what if repair cost is less than deductible.
| Repair cost | Deductible | Insurer payout | Decision |
|---|---|---|---|
| $400 damage | $500 | $0 (under deductible) | Do not file. Nothing to collect, and even a reported-only loss can appear on CLUE for future quotes. |
| $1,500 damage | $500 | $1,000 | Marginal. A $1,000 recovery is often less than the multi-year surcharge if the loss is at-fault and chargeable. Surcharge typically runs 3 to 5 years at carrier-filed rates; shop at renewal. |
| $5,000 damage | $1,000 | $4,000 | File. The recovery exceeds a typical multi-year surcharge impact at most carrier filings; use accident forgiveness if the endorsement was in force. |
Three considerations the raw math leaves out: a not-at-fault loss is generally non-chargeable (see rate impact by claim type); even a closed-without-payment report can appear on CLUE at some carriers; and the surcharge stack is a rolling clock, so an accident filed late in one carrier's window can still produce multi-year effects at the next.
