Auto Insurance Quote Calculator — 2026 Monthly Premium by Age, Record, Vehicle & ZIP

As of April 2026, the US national average for full coverage auto insurance is roughly $177 per month ($2,314 per year), while minimum-coverage liability averages about $54 per month ($644 per year). The typical range spans $55/mo for state-minimum liability on a clean 45-year-old driver in rural Iowa to $320/mo for premium full coverage on a 35-year-old in New York City. Teenage drivers average $369/mo for full coverage — and a 16-year-old in New York State can hit $609/mo. Michigan full coverage averages $270+/mo due to its no-fault unlimited-medical law; Florida averages $311/mo.

• Minimum liability: $55–$75/mo (state-minimum, varies by state)
• Liability-only 50/100/50: $75–$110/mo
• Standard full coverage 100/300/100: $150–$220/mo (national avg $177/mo)
• Premium full coverage + low deductible: $220–$320/mo
• Teen / new driver: $350–$500/mo for full coverage
• DUI conviction: 1.8–3x baseline premium for 3–5 years

Teenage drivers pay dramatically more than any other age bracket. Sixteen-year-olds average $436–$478/mo for full coverage nationally and can hit $609/mo in New York. Premiums drop roughly 20% at age 25 as drivers move out of the "inexperienced" class, and the 35–54 bracket is the cheapest band, averaging $90–$175/mo. Rates tick up modestly at 65 and climb more sharply past 75 as crash frequency rises. Adding a teen driver to a parent's policy typically adds $150–$300/mo to the family's total bill.

• Under 21: $250–$500/mo (highest band, 2–3x the 35–54 baseline)
• 21–24: $150–$280/mo, drops ≈20% at age 25
• 25–34: $110–$200/mo
• 35–54: $90–$175/mo (cheapest band, the reference baseline)
• 55–64: $95–$170/mo
• 65+: $100–$190/mo with senior uplift over age 70

A single at-fault accident lifts the national average full-coverage premium from roughly $2,524/yr to $3,836/yr — an extra $110/mo on average, and the surcharge typically runs for 3–5 years. A single DUI raises the national average to about $4,850/yr, which is $391/mo for full coverage. In eleven states (including California, Georgia, Michigan, and Minnesota) a DUI more than DOUBLES the premium; North Carolina quadruples it. Most carriers also require an SR-22 filing ($15–$50 fee) for 3–5 years. Two at-fault accidents in a five-year window will push many standard carriers to non-renew — you then move into the non-standard market (Dairyland, The General, Bristol West) at 2–4x baseline.

• At-fault accident: +35–55% for 3–5 years
• Speeding ticket (1 point): +15–30% for 3 years
• DUI national average increase: +80–100%, some states +200%+
• SR-22 filing fee: $15–$50 one-time, held 3–5 years
• Two at-fault accidents: typical standard-carrier non-renewal trigger
• Non-standard market (post-non-renewal): 2–4x baseline

Yes, in 46 of 50 states. Drivers with poor credit pay an average of $2,602/yr for full coverage versus $1,853/yr for excellent-credit drivers — a 40% premium penalty, or about $62/mo. In some states the gap exceeds 76% and in a handful of outlier states can reach 336%. Credit is NOT allowed as a rating factor in California, Hawaii, Massachusetts, or Michigan; Maryland, Oregon, and Utah restrict but do not ban it. If you are in a state that prohibits credit-based rating, select the "Not used" option for the most accurate estimate. Every 100-point improvement in your score typically cuts 5–15% off the premium at renewal.

• Excellent credit (740+): baseline
• Good credit (670–739): −0 to −5% vs baseline
• Fair credit (580–669): +10–25%
• Poor credit (<580): +40–80% in most states, up to +336% in outliers
• Credit banned in rating: CA, HI, MA, MI
• Credit restricted: MD, OR, UT

Florida, Michigan, Louisiana, Nevada, and New York consistently rank as the five most expensive auto insurance states. Michigan averages $270+/mo for full coverage because of its no-fault unlimited-medical law, which forces insurers to underwrite lifetime injury care on every policy. Florida averages $311/mo due to a high uninsured-driver rate (20%+ in some counties), heavy traffic congestion, and hurricane/flood comprehensive exposure. New York is driven by dense urban theft rates and no-fault PIP minimums. Rural Midwest states (Iowa, Ohio, Wyoming, Idaho) run 20–35% below the national average. California is mid-range at $221/mo and cannot use credit or gender as rating factors.

• Michigan: avg full coverage $270+/mo (no-fault unlimited medical)
• Florida: avg full coverage $311/mo (3rd highest nationally)
• Louisiana, Nevada, New York: top 5 most expensive
• California: $221/mo (credit + gender prohibited as factors)
• Rural Midwest (IA, OH, WY, ID): 20–35% below national avg
• Top 5 cheapest states: Vermont, Maine, New Hampshire, Idaho, Ohio

The biggest single lever is bundling home or renters insurance with auto — typical savings 8–25%. Raising your collision and comprehensive deductible from $500 to $1,000 cuts the full-coverage portion of your premium 15–20%. Dropping collision and comprehensive on a car worth less than $4,000 (market value divided by annual comp+collision premium less than 10× is the break-even) moves you to liability-only and can halve the premium. Low-mileage discounts trigger under 7,500 miles/yr, telematics programs (Progressive Snapshot, State Farm Drive Safe & Save, GEICO DriveEasy) reward brake-smoothness and late-night avoidance with 10–25% cuts, and paying the six-month premium in full routinely saves 3–8% over the monthly-installment fee.

• Bundle home + auto: 8–25% discount with most carriers
• $500 → $1,000 deductible: cuts full-coverage portion 15–20%
• Drop comp/collision on car worth <$4,000: can halve premium
• Low-mileage (<7,500 mi/yr): 5–15% discount
• Telematics (Snapshot, Drive Safe, DriveEasy): 10–25% cut
• Pay-in-full 6-month premium: 3–8% savings vs monthly
