Auto Insurance Premium Calculator

Credit-based insurance scoring is a real, statistically-grounded rating practice used by most auto insurers in most U.S. states -- studies have found a correlation between credit-based scores and claims frequency. That said, it is restricted or banned in a handful of states (including California, Hawaii, and Massachusetts), so whether it applies to your actual quote depends on where you live and which insurer you use. Treat the Credit Factor here as illustrative of common industry practice, not a universal rule.

A higher deductible means you agree to pay more out of pocket before insurance coverage kicks in on a claim, which lowers the insurer's expected payout per claim -- insurers pass that reduced risk back to you as a lower premium. This calculator's Deductible Factor steps down at $500, $1,000, and $2,000 deductible thresholds, each unlocking a bigger discount.

Age Factor is deliberately non-monotonic: it's elevated for drivers under 25 (reflecting statistically higher accident rates for less-experienced younger drivers), flat at the baseline multiplier between 25 and 65, and rises again gradually past 65. This U-shaped pattern mirrors how real insurers commonly structure age-based rating, though the exact breakpoints and magnitudes vary significantly by company and state.

No -- they're illustrative multipliers built to mirror the general shape of real auto insurance rating (higher risk factors raising the base rate, lower risk factors and higher deductibles reducing it), not actual filed rate data from any specific insurer. Real premiums come from an insurer's actuarially-developed rating plan, which is filed with and approved by state insurance regulators and varies by company, state, and your specific driving record.

It doesn't include your actual claims history, moving violations, vehicle safety/theft ratings, marital status, or usage-based (telematics) discounts, all of which real insurers commonly factor into pricing. It also doesn't distinguish liability-only from full (collision + comprehensive) coverage beyond the deductible input. Use this as a rough planning estimate, then get actual quotes from insurers licensed in your state for a real number.
