Figures reflect 2026 rate analyses from Bankrate, MoneyGeek, ValuePenguin, The Zebra, and Insurify unless a different year is noted inline; individual quotes vary by carrier, state, and driver profile.
TL;DR — Quick Verdict
- Drivers with poor credit pay roughly 98% more for full coverage than drivers with good credit nationally, per ValuePenguin’s 2026 analysis — an average gap near $3,838 per year according to MoneyGeek.
- The insurer you pick matters more than the credit gap itself: GEICO charges a poor-credit driver about $212 per month while State Farm charges about $590 for the identical profile (MoneyGeek, 2026).
- Four states — California, Hawaii, Massachusetts, and Michigan — ban credit-based insurance scoring for auto policies entirely.
- Comparison result: shopping three or more carriers beats waiting for a credit rebuild, because the carrier penalty spread (GEICO vs. State Farm) can exceed the credit penalty.
- Recommendation: if your credit is fair or poor, quote credit-lenient carriers first, then improve credit for a second-round re-rate at renewal.
Two drivers park identical 2017 Honda Accords in the same ZIP code with spotless driving records. One pays $1,853 a year for full coverage; the other pays $2,602. The only difference is a three-digit number neither of them earned behind the wheel. That 40% gap comes from Insurify’s 2026 rate study, and it sits at the conservative end of the range — Bankrate’s November 2025 study found the spread can reach 105% depending on the carrier, and MoneyGeek’s 2026 analysis pegs the average annual difference at $3,838.
Insurers call the number a credit-based insurance score, and roughly 95% of auto carriers use one, according to FICO. It is not your FICO lending score, though it is built from the same credit report. This article breaks down verified 2026 rates by credit tier, shows which major carriers — GEICO, State Farm, Progressive — punish poor credit hardest, identifies the states where the practice is banned outright, and models whether shopping or credit repair saves you more money faster. Every figure below traces to a named rate study or a government source.
What Poor Credit Actually Costs: 2026 Rates by Tier
Start with the dollars. Across major carriers and states, ValuePenguin’s 2026 research finds poor credit raises full coverage rates by 98% compared to good credit — a driver with bad credit pays roughly $204 more per month, or about $2,448 more per year, than a good-credit driver with an identical record. The Zebra’s 2026 study, which examined more than 83 million quotes, stretches the extremes further: drivers in the Very Poor tier (below 523) average $6,254 per year for full coverage, while Exceptional-credit drivers (823+) pay $1,673 — a $4,581 gap that represents a 273% increase for the lowest tier.

The tiers matter because the jump is not linear. Moving from Poor to Fair delivers a larger percentage saving than moving from Good to Excellent, which is why the fastest financial wins come from escaping the bottom tier. If your rate already reflects a recent accident, credit stacks on top of that surcharge — the two penalties compound rather than cancel. Drivers weighing whether to file at all should first review how a claim affects your premium before assuming credit is the only lever.
How a Credit-Based Insurance Score Is Built
Your lender’s FICO score and your insurer’s score share a source but not a formula. According to the NAIC, a credit-based insurance score weighs payment history at 40%, outstanding debt at 30%, credit history length at 15%, new credit inquiries at 10%, and credit mix at 5%. Income and employment are excluded entirely — the model predicts claim likelihood, not loan repayment.
Consider a real-world scenario. A 34-year-old renter carries three credit cards near their limits and missed two payments last year. Her utilization and payment history — the two heaviest factors, 70% of the score combined — drag her into the poor tier. She has never had an accident. Under a typical carrier’s model, she still pays close to double what her neighbor with the same car and record pays, purely on that score. The FTC’s 2007 Report to Congress, still the definitive federal study, concluded that these scores are effective predictors of both the number of claims a consumer files and the total cost of those claims — the statistical basis insurers cite for the practice.
Two mechanical details change your strategy. First, quoting a policy triggers only a soft credit pull, so shopping never dents your score. Second, most carriers re-check credit at each 6- or 12-month renewal, which means an improvement translates into a lower rate on a predictable schedule rather than immediately. Drivers rebuilding credit should time a re-quote to land just after a renewal review. Those exploring other levers can compare telematics and usage-based savings, which price on driving behavior instead of credit.
GEICO vs. State Farm: Which Is Better for Poor-Credit Drivers?
The single most expensive mistake a poor-credit driver makes is assuming all insurers penalize credit equally. They do not — and the spread between them frequently dwarfs the credit gap itself. MoneyGeek’s 2026 analysis puts hard numbers on it: for the same driver, same car, and same coverage, GEICO charges a poor-credit driver about $212 per month, while State Farm charges about $590. That $378 monthly difference — roughly $4,536 a year — has nothing to do with how bad the credit is and everything to do with each company’s internal formula.

Verdict
For a driver with poor credit, GEICO is the stronger starting point — its penalty is a fraction of State Farm’s for the identical profile. But “better” is profile-specific: State Farm may win for a driver with excellent credit and a bundled home policy. The rule is not “pick GEICO,” it is “quote at least three carriers before renewing,” because the carrier you default to can cost more than your credit does.
This is why brand-name loyalty is expensive for poor-credit drivers. Before committing, weigh each insurer’s claims reputation alongside price using independent claims ratings and price data, and check whether stacking a multi-car or home bundle discount closes the remaining gap.
Where Credit Can’t Touch Your Rate: The Four Banned States
Geography can erase the credit penalty completely. Four states prohibit auto insurers from using credit information to set rates: California, Hawaii, Massachusetts, and Michigan. In these states, every insurer automatically skips the credit check, and a poor score costs you nothing on premium.
The bans arrived by different routes. California outlawed the practice in 1988 under Proposition 103, which limits auto rating to driving record, annual mileage, and years of experience. Michigan eliminated credit scoring as part of its 2019 no-fault insurance reform; The Zebra reports that before the ban, Michigan poor-credit drivers paid around $8,640 for full coverage — 271% more than the $2,326 excellent-credit drivers paid — and now everyone averages roughly $3,096 regardless of credit. Hawaii and Massachusetts bar the practice to protect lower-income residents.
Three more states — Maryland, Oregon, and Utah — restrict rather than ban credit use, typically forbidding insurers from denying coverage or raising renewal premiums on credit alone. Legislators in New York, Pennsylvania, Oklahoma, and Iowa introduced bills in 2026 to expand restrictions, though none had taken effect at publication. Because rules and base rates diverge so sharply, comparing average premiums by state is the fastest way to see where you stand, and drivers who move across state lines should re-quote immediately rather than assume portability.
What Most People Get Wrong About Credit and Premiums
Three misconceptions cost drivers real money every renewal cycle.
Mistake 1: Believing a quote hurts your credit. The consequence is that fearful drivers stop shopping and overpay indefinitely. The correct action: quote freely — insurers use a soft pull that never affects your score, so there is no downside to comparing every renewal.
Mistake 2: Waiting for a “perfect” score before switching carriers. The consequence is months of inflated premiums while you rebuild. Because the GEICO-versus-State-Farm spread can exceed the credit penalty, the correct action is to switch to a credit-lenient carrier now and improve credit in parallel, capturing both savings.
Mistake 3: Assuming paying your insurance bill builds credit. The consequence is misplaced effort. Insurers typically do not report premium payments to the bureaus, so on-time premium payments do not lift your score. The correct action: focus credit effort on the two factors that move the insurance score most — payment history and lowering utilization. Experian recommends keeping card balances below 30% of the limit. Drivers who have had a lapse or a serious violation should also verify whether an SR-22 filing applies, since that requirement stacks its own cost on top of credit.
Is Fixing Your Credit Worth It? Run the Math
Whether credit repair pays off depends on your starting tier and your timeline. The conditional logic is straightforward. If you sit in the Poor tier and your carrier penalizes credit steeply, the payoff is large: escaping to the Fair tier can trim hundreds to over a thousand dollars annually, and the biggest percentage drop happens on that first tier jump. If you are already in the Good tier, the marginal gain from reaching Excellent is smaller — often a single-digit-percentage reduction — so your effort may be better spent on deductible or coverage optimization.
Model it with your own numbers: take your current full-coverage premium, apply the ~98% national poor-to-good gap from ValuePenguin as a ceiling, and treat one tier of improvement as capturing roughly a third to a half of that gap over 6–12 months. A driver paying $4,500 with poor credit could plausibly see $1,000–$1,500 in annual savings from a one-tier improvement plus a carrier switch — but only if the new carrier is credit-lenient. Pair the credit work with structural moves: raising your deductible and confirming you carry the right coverage mix can compound the savings.
Worth it for whom? Drivers in the Poor or Fair tiers with a 6–12 month horizon get the clearest return. Drivers in banned states get nothing from credit repair on the auto side and should skip it as an insurance strategy. Everyone benefits from shopping first — it is free, instant, and frequently outperforms months of credit rebuilding.
Frequently Asked Questions
How much more does poor credit cost per year?
Nationally, poor credit raises full coverage premiums about 98% versus good credit, according to ValuePenguin’s 2026 analysis — roughly $2,448 more per year. MoneyGeek’s 2026 study puts the average gap at $3,838, and The Zebra found a $4,581 spread between its Very Poor and Exceptional tiers. Your figure depends heavily on your carrier and state.
Does getting a quote lower my credit score?
No. Insurers use a soft credit pull to generate quotes, which does not affect your credit score and is not visible to lenders as a hard inquiry. You can compare quotes across as many carriers as you want at renewal with zero credit impact — one reason shopping every cycle is the lowest-risk way to cut your premium.
Which states ban credit scoring for car insurance?
California, Hawaii, Massachusetts, and Michigan ban auto insurers from using credit-based insurance scores entirely. California’s ban stems from 1988’s Proposition 103; Michigan’s came with its 2019 no-fault reform. Maryland, Oregon, and Utah restrict the practice without a full ban. In these four banned states, a poor credit score costs you nothing on your auto premium.
How fast can improving credit lower my rate?
Most insurers re-check credit at each 6- or 12-month renewal, so improvements typically show up at your next renewal rather than instantly. The Zebra found that improving credit by one tier yields an average 54% rate reduction. Some carriers permit a mid-term re-rate if you request one after a significant credit improvement.
How We Researched This Article
This analysis synthesizes 2026 rate studies from five independent research operations alongside two federal and one state-regulatory primary source. Premium figures by credit tier were drawn from ValuePenguin’s 2026 rate analysis, MoneyGeek’s 2026 credit-impact study, and The Zebra’s 2026 examination of more than 83 million quotes. Carrier-specific penalty spreads (GEICO versus State Farm) come from MoneyGeek’s matched-profile modeling, in which a single driver profile — same vehicle, record, and coverage — is quoted across carriers to isolate the credit variable. These carrier figures are modeled from rate filings, not measured from individual policyholder bills, and real quotes vary.
The scoring-factor weights (payment history 40%, outstanding debt 30%, length 15%, new credit 10%, mix 5%) reflect NAIC and FICO documentation. The finding that credit-based insurance scores predict claim frequency and cost comes from the FTC’s Report to Congress on Credit-Based Insurance Scores, the definitive federal study, supplemented by the NAIC’s regulatory brief and Experian’s state-by-state restriction summary. State ban details were cross-checked across NAIC, The Zebra, and Experian.
Limitations: national averages mask wide state and carrier variation, and mid-tier point figures (Good, Fair) differed enough across studies that we report them as ranges rather than single numbers. Carrier penalty figures are modeled estimates. This research was last conducted July 2026. All figures were verified against named primary sources before publication.
