About Auto Insurance Calculator

Calculate auto insurance premiums based on vehicle and driver profile. Part of the DevTools Surf developer suite. Browse more tools in the Calculators collection.

Use Cases

• Estimate annual insurance cost before purchasing a new vehicle
• Compare coverage levels to find the right deductible/premium balance
• Model the premium impact of adding a young driver to a policy
• Understand which vehicle features affect insurance rates

Tips

• Enter your vehicle's year, make, and model accurately — these drive the collision rate tables that determine the bulk of the premium estimate
• Compare liability-only vs full coverage outputs; full coverage on vehicles older than 10 years often costs more than the vehicle's actual cash value
• Adjust the deductible slider — raising from $500 to $1,000 typically reduces comprehensive/collision premiums by 10-15%

Fun Facts

• The first auto insurance policy in the US was issued in 1897 in Dayton, Ohio, to Gilbert Loomis — for a single-cylinder Winton automobile, at a premium of $7.50 for $500 of coverage.
• US auto insurance premiums rose by 26% in 2023 alone — the largest single-year increase in 40 years — driven by repair cost inflation, supply chain disruptions raising parts prices, and increased accident severity.
• Telematics (usage-based insurance) programs track acceleration, braking, and cornering via smartphone or OBD-II plug-in. Safe drivers can earn discounts of up to 30% — a form of individual actuarial pricing previously impractical.

FAQ

How accurate is the estimate?

This calculator uses actuarial rate tables for illustrative estimates. Actual premiums from insurers incorporate proprietary credit scores, claims history, and local market factors not available in a generic tool.

What factors most affect auto insurance premiums?

Driving record (accidents/violations), age and gender of drivers, vehicle make and model (repair cost, theft rate), coverage limits, deductibles, annual mileage, and location (ZIP code accident rates).

What is the minimum coverage required by law?

Minimum requirements vary by state. Most require liability coverage (bodily injury and property damage). Some states require personal injury protection (PIP) or uninsured motorist coverage. No state requires collision or comprehensive.
