Find your limits

Answer what applies. Only your state is required. The result is a recommended liability limit set and the reasoning behind it, never a price. The second group of questions is about what a lawsuit could reach. This calculator runs in your browser and does not send the numbers you enter.

Your recommendation

This calculator needs JavaScript. The method: add home equity, savings and investments, and other assets; pick the smallest standard limit set whose per-accident bodily injury limit covers that total and your state's minimum, with at least $50,000 of property damage.

Methodology and sources

What a lawsuit could reach is home equity plus savings and investments plus other assets. Retirement accounts often receive protection from creditors, and homestead protections vary widely by state. We excluded retirement balances from this estimate, and you should confirm your own state's exemptions with an attorney before relying on any of this.

The recommended per-accident bodily injury limit is the larger of that total and your state's minimum, snapped up to the smallest of these standard limit sets with at least $50,000 of property damage: 50/100/50, 100/300/100, 250/500/100, 250/500/250, 500/500/500, 500/1000/500. Because of that property damage floor, the lowest recommendation is 50/100/50, never the 25/50/25 set some carriers sell. Above 500/1000/500, the recommendation becomes maximum available auto limits plus a personal umbrella policy. This ladder is FinanceRazor's own heuristic, not a figure published by any regulator.

It derives from the NAIC: "You should consider buying more coverage than the law requires because accidents happen every day, even to good drivers. If you do not have enough liability coverage, and you are found at fault for an accident, you would be responsible to pay for anything your insurance does not cover." And: "You should purchase the most coverage you can reasonably afford to protect your financial security."

State minimums come from the Triple-I's Automobile Financial Responsibility Limits By State table, which the Triple-I sources to the American Property Casualty Insurers Association and state departments of insurance. Where that table lags state law, we use the state's own source, checked October 1, 2026: California (California DMV and California Department of Insurance), Florida (Florida Department of Highway Safety and Motor Vehicles), Hawaii (Hawaii Insurance Division), Massachusetts (Massachusetts Division of Insurance), Michigan (Michigan Department of Insurance and Financial Services, lowest allowed limit), New Jersey (New Jersey Department of Banking and Insurance), New York (New York Department of Financial Services), North Carolina (North Carolina Department of Insurance), Tennessee (Tennessee Department of Revenue), Utah (Utah Code section 31A-22-304) and Virginia (Virginia DMV).

Triple-I: "State laws regarding mandatory requirements for uninsured and underinsured motorists vary. State departments of insurance should be consulted to determine whether these coverages are compulsory."

Uninsured motorist shares are 2023 estimates from the Insurance Research Council, published by the Triple-I (countrywide 15.4 percent). They set how strongly the result talks about uninsured motorist coverage, never the limit.

Disclaimer

This calculator provides general educational information, not insurance advice, legal advice, or a coverage recommendation for your specific situation. It does not estimate or quote premiums. State minimum liability limits shown are from the Insurance Information Institute's Automobile Financial Responsibility Limits By State table, accessed August 6, 2026 and rechecked October 1, 2026, which the Triple-I sources to the American Property Casualty Insurers Association and state departments of insurance, except where that table lags state law; for those states the limit shown is taken from the state's own DMV or insurance department source, checked October 1, 2026. Requirements change and your state's insurance department is the authority. The recommended limit ladder is FinanceRazor's own heuristic, derived from the NAIC's published guidance that consumers should "purchase the most coverage you can reasonably afford to protect your financial security." It is not a standard published by any regulator. Asset protection rules, including homestead and retirement account exemptions, vary significantly by state; consult a licensed attorney about your own exposure. Confirm all coverage decisions with a licensed insurance agent before you buy.

How to use this calculator

Pick your state, the only required answer. Then add what you can: whether the car is owned, financed or leased, what a lawsuit could reach (home equity, savings, other assets), who drives in your household, and the limits on your declarations page.

The result is a liability limit set, such as 100/300/100, with the reasons behind it and your state's legal minimum beside it. It never shows a price. To price it, get quotes for the same limits from several insurers, as the NAIC's shopping guide advises. The limit ladder is FinanceRazor's own heuristic, not a regulatory standard.

What do liability limits like 50/100/50 mean?

The numbers are thousands of dollars. Using the NAIC's explanation of the three numbers, 50/100/50 pays at most $50,000 for injuries to any one person, $100,000 for all injuries in one accident, and $50,000 for property you damage. Liability pays other people, never your own car.

Past the limit, the bill is yours. The NAIC says that if you are at fault without enough liability coverage, "you would be responsible to pay for anything your insurance does not cover."

Why are state minimums so low?

A minimum is a legal floor, not an estimate of what a crash costs. Pennsylvania's Insurance Department lists $15,000 per person, $30,000 per accident and $5,000 of property damage. The Texas Department of Insurance warns that its 30/60/25 minimum "might be too low if you cause a multi-vehicle accident or the other driver's car is totaled." Hawaii raised its minimum to 40/80/20 in 2026, and its Insurance Division still says "serious accidents can exceed these amounts." Your state is in minimum car insurance by state.

Other drivers may carry low limits or none. Triple-I, citing the Insurance Research Council, says 15.4 percent of motorists were uninsured in 2023. The result sets uninsured and underinsured motorist coverage to the same limits as your recommended liability limits; your state's uninsured share changes how strongly it makes that point, not the limit.

When does an umbrella policy make sense?

A personal umbrella pays liability and defense costs above your auto and home limits. The Massachusetts Division of Insurance says it pays only after your primary policy limits are used up, is usually sold in million dollar increments, and that "the more assets you have, the more you are at risk." The result suggests one when what a lawsuit could reach passes $500,000.

An umbrella requires underlying auto limits, and if you let them lapse, the Massachusetts page says, it treats them as a deductible you pay yourself. See umbrella underlying limits.

FAQ

Is my state's minimum enough car insurance?

It keeps you legal but may not protect your savings. The NAIC advises buying "the most coverage you can reasonably afford to protect your financial security."

What happens if damages go over my liability limits?

The NAIC says you "would be responsible to pay for anything your insurance does not cover," and the injured person can sue you for it. What can be collected, and what is protected, varies by state, so ask an attorney.

Does higher liability coverage pay for my own car?

No. Collision and comprehensive cover your car. The liability-only break-even calculator shows whether they still make sense on a paid-off car.

Should uninsured motorist limits match my liability limits?

That is the default here. The NAIC says uninsured motorist coverage pays your and your passengers' injuries when an uninsured at-fault driver hits you, and underinsured coverage applies when that driver's limits fall short.

Do I need to list a student away at school?

Usually yes. The NAIC says a policy should cover all household members, "including students away at school," because you "may be responsible for any damages or injuries they cause."
