Directional estimates only. Real premiums depend on your full underwriting profile and insurer algorithms. Always compare quotes from multiple carriers.

How We Estimate Rate Ranges
This calculator uses a weighted scoring model based on publicly available rate-filing data, actuarial research, and industry averages from sources such as the Insurance Information Institute, NAIC, and state insurance department filings.
Each input is assigned a weight reflecting its typical directional impact. A recent DUI carries a high positive weight (rate increase), while bundling home and auto carries a negative weight (rate decrease). These weights are summed into a composite score mapped to a percentage range.
A state-level cost multiplier adjusts the range — high-cost states (FL, MI, NY) apply 1.15x to positive impacts, while low-cost states (ME, VT, ID) apply 0.9x.
The resulting range is intentionally wide to reflect the significant variation between insurers. Two companies can quote the same driver rates that differ by 50% or more, which is why comparing quotes is the single most effective way to save.
Is this an exact insurance quote?
No. This calculator provides a directional estimate based on industry averages and weighted scoring models. It is not a substitute for an actual insurance quote.
Real insurance premiums are determined by each insurer's proprietary rating algorithm, which considers hundreds of variables that this tool does not capture. For an actual price, we recommend comparing quotes from at least three carriers. Get a quick quote here →
Does checking rates hurt my credit score?
No. Checking insurance rates or using this calculator does not affect your credit score in any way.
Insurers perform a "soft inquiry" which does not impact your FICO score. This calculator doesn't access your credit report at all — everything runs in your browser. Learn more about credit scores and insurance →
Why did my rate go up even though I had no accidents?
Insurance rates can increase for many reasons beyond your personal driving record, including inflation, rising repair costs, increased claims frequency in your area, and regulatory changes.
The best response to an unexpected rate increase is to compare quotes from competing insurers. Understand all the factors that affect your rate →
What's the fastest way to lower my auto insurance premium?
Compare quotes from at least three insurers. Beyond that, bundling policies, raising your deductible, and asking about every available discount can produce immediate savings.
Quick wins: bundle home + auto (5–15%), switch to autopay and paperless (3–5%), pay annually (5–10%), raise your deductible to $1,000 (15–25%). See all auto insurance discounts →
Why do two insurers give such different prices for the same driver?
Each insurer uses its own proprietary rating algorithm with different weightings for the same factors.
A carrier that specializes in high-risk drivers may offer competitive rates for someone with a DUI, while a standard carrier charges a steep surcharge. This variation is exactly why comparing multiple quotes is so important. Learn how to effectively compare quotes →
How many quotes should I compare?
We recommend comparing at least three to five quotes to get an accurate picture of the market.
The more quotes you compare, the more likely you are to find a carrier whose rating model favors your profile. Start comparing quotes now →
