How This Estimate Is Built
The tool starts from a base annual premium, then adjusts it for the things insurers actually rate on: how much your car is worth, how old it is, how old you are, the coverage level you choose, and the state you drive in. Full coverage adds a comprehensive and collision charge tied to vehicle value, while minimum liability strips most of that out.
What Moves Your Car Insurance Rate
Carriers price auto insurance on risk and replacement cost. Younger drivers and brand new drivers pay more because crash data says they file more claims. A newer, pricier car costs more to insure for comprehensive and collision because the insurer could have to repair or replace it. Your record matters too: tickets and at-fault accidents push the number up, often for three to five years. According to the Insurance Information Institute, the average annual cost of full coverage runs well above minimum liability, which is why the coverage level you pick changes the result so much.
Use the range above to sanity check a quote you already have. If an agent's number lands far above this estimate, ask what is driving it. If it lands far below, check that the liability limits and deductibles actually match what you picked here, then compare at least three carriers before you buy.
Calculator methodologyCar Insurance Reference Data
The constants this calculator runs on are published in full on the 2026 Insurance Needs Formulas Reference, alongside the other eight tools on this site. Nothing below is invented for this page; it is the same base rate and multiplier the calculator above uses.
| Component | How it prices |
|---|---|
| Base liability | $620/yr |
| Comp and collision | Vehicle value × age depreciation × 3.4% × state factor |
| Default profile result | $940/yr ($78.33/mo) |
Default profile: $25,000 vehicle, 4 years old, age 35 driver, standard coverage, national-average state. Full methodology, every constant, and the downloadable CSV live on the reference page above.
