01A legal minimum is not a coverage recommendation
State requirements set a legal floor, not a promise that the limits will cover a serious injury or repair bill. The floors also change. North Carolina moved to 50/100/50 for new and renewed policies from July 1, 2025. Massachusetts moved to 25/50/30 on the same date, and Hawaii moved to 40/80/20 for new and renewed policies from January 1, 2026.
Liability is written as bodily injury per person, bodily injury per accident, then property damage. A 30/60/15 policy can therefore leave a large gap even though it satisfies the applicable minimum. If a covered claim exceeds a policy limit, you may be personally responsible for the remainder.
The calculator uses net worth only as an educational asset-protection guide. It checks per-person injury, per-accident injury and property-damage limits separately.
- Liability covers injuries and damage you cause to others, subject to the policy.
- Collision and comprehensive cover defined damage to your own vehicle; they are not liability coverage.
- Uninsured and underinsured motorist rules vary, and required coverage may already be inside a quoted policy.
02Compare four tiers without mixing coverage types
State minimum applies the listed legal floor. Standard is liability-only at 50/100/50. Full uses 100/300/100 plus collision and comprehensive, while High uses 250/500/250 plus the same physical-damage coverage. Raising liability limits does not magically increase the value of your car, so the High tier does not reprice physical damage merely because liability is higher.
The phrase full coverage is a convenient comparison label, not a promise that every loss is covered. Exclusions, deductibles, actual cash value, optional benefits and state-specific required coverages still matter. Read the declarations page and policy before treating two quotes as equivalent.
- A lender or lessor may require collision and comprehensive even when the state does not.
- Gap exposure here is the positive difference between your entered payoff and vehicle value; an actual gap contract can have caps and exclusions.
- If you could not replace the car without insurance, that is a reason to review physical-damage coverage even when no lender requires it.
03How the premium estimate is built
The 50 state premium anchors match Forbes Advisor state rates audited July 23, 2026. Its compatible full-coverage benchmark uses a 40-year-old female driver, a new Toyota RAV4, 100/300/100 liability, 100/300 uninsured motorist coverage, and collision and comprehensive with a $500 deductible. Its published national averages are $2,459 for full coverage and $788 for minimum coverage; those national figures are not an average of the 50 state rows.
For modeling, the full-coverage anchor is split into 55% liability and UM and 45% physical damage. That allocation is a disclosed assumption, not an insurer filing. Standard liability-only interpolates between the state minimum anchor and the liability component of the full anchor. Vehicle value and deductibles affect physical damage only.
Age, record, mileage and the other visible adjustments are illustrative. Selected verified statewide restrictions suppress factors where they cannot be used as modeled: for example, the credit adjustment is not applied in California, Hawaii, Massachusetts or Michigan. The result remains a per-car estimate when you test a multi-vehicle adjustment.
04Read the deductible and discount comparisons correctly
Every deductible alternative holds the driver, coverage, rating adjustments and optional add-ons constant. That prevents an add-on or payment-plan change from masquerading as a deductible saving. Break-even divides the extra claim out-of-pocket by the annual premium saving, then converts the result to months.
A higher deductible is not automatically better. It lowers the illustrated physical-damage premium but increases what you pay on a covered claim. Emergency savings, claim likelihood, lender rules and the actual policy all belong in that decision.
The adjustment stack uses signed amounts. A saving is shown with a minus sign and a surcharge with a plus sign. Optional coverages are listed separately, and the multi-car selection does not turn the result into a household policy total.
05What this estimate cannot know
A carrier can use ZIP-level territory, exact vehicle, driving experience, household drivers, prior claims, underwriting rules and discount eligibility that this anonymous model does not reproduce. Different insurers can quote materially different prices for the same person and coverage. Use the estimate for planning, then request several quotes with identical limits and deductibles.
The current Forbes table omits Washington, D.C. Swiftly retains a prior-series D.C. anchor and labels that limitation rather than assigning it to the current table. Legal minimums and selected rating restrictions are checked against regulators or statutes separately from the premium source; neither source type makes the result a bindable quote.
