Choosing liability limits for five different households
Five fictional households, one method: what a judgment could reach, which limit tier fits, and when an umbrella policy is the cheaper way to add protection.
The right liability limit is the one that covers a serious injury claim you could realistically cause, measured against what a court judgment could take from you: assets you hold now and income you will earn later. For a household with little to lose, that is still usually well above the state minimum. For a household with a home, savings and a high income, it usually means 250/500/100 or more, with an umbrella policy on top. The best way to see why is to run the same method on different families.
The five households below are invented for illustration. Every dollar figure is a made-up example, not market data, and the limits they land on are examples of reasoning, not recommendations for any real person. The general version of this question is covered in how much liability coverage do you need?; this article is the worked-example companion.
The method: five questions to ask before picking a number
Every household below goes through the same five steps.
- What can a judgment reach today? Bank and brokerage balances, home equity, a second car, a rental property, cash value in a life policy. Some assets are partly or fully protected by law, which comes up in the profiles.
- What can it reach tomorrow? A judgment is usually collectible for many years and in many states can be renewed. Wages can be garnished, and a person who is a student or has just started a career may have little today but a lot of future income.
- How bad could a crash be? Not the average claim, which is modest, but a bad one: a surgeon-level medical bill, months off work, a permanent injury, or a death. The Insurance Research Council reported in 2026 that average bodily injury payments rose from roughly $14,000 in 2017 to more than $20,000 in 2022, but the claims that matter for limit-setting are the rare ones far above that average.
- Which tier fits? The common choices are the state minimum, 50/100/50, 100/300/100 and 250/500/100. Not sure how to read those numbers? The liability limits decoder and what 25/50/25 means: split liability limits explained explain the three-number format.
- Is an umbrella cheaper than raising the auto limit? Often, once the auto limit reaches a certain point.
A note on step 2: the federal Consumer Credit Protection Act caps ordinary wage garnishment. The Department of Labor's Fact Sheet #30 (December 2024) says the weekly amount may not exceed the lesser of 25% of disposable earnings or the amount by which disposable earnings exceed 30 times the federal minimum wage, and that when a state law would garnish less, the lower amount governs. That limit protects a paycheck from being emptied. It does not make a person judgment-proof: 25% of a good income, taken year after year, is a lot of money.
Household one: the renter with a car loan
The facts. Dana is 27, rents an apartment, earns $48,000, has $9,000 in savings and a $400 monthly car loan on a three-year-old sedan. She owns nothing a court would find tempting.
What a judgment can reach. Very little today. Ordinary renters are not unusual here: the Federal Reserve's 2022 Survey of Consumer Finances put median net worth for renters at about $10,400, against about $396,200 for homeowners and $192,900 for all families. But Dana's future matters more than her present. A judgment against her could follow her for years, with a quarter of her disposable pay at risk, while she tries to save for a first home.
What a bad crash looks like. She runs a red light and hits a motorcyclist, who has a leg amputation and a year out of work. A claim in that range can run into the hundreds of thousands of dollars.
Where the limits land. The state minimum is too thin for this risk, and many states' minimums are well below $50,000 per person (check yours with state car insurance requirements lookup). For Dana, 50/100/50 is a floor, and 100/300/100 is a reasonable step if the quote allows it. The reasoning is not that her savings are in danger. It is that her next ten years of paychecks are. Raising bodily injury limits costs far less than most people expect (the mechanism is in why doubling liability limits does not double the premium), and property damage of $50,000 or more is realistic because of the cars on the road today (see why property damage limits fall short in today's crashes).
What she can skip. An umbrella. She has no assets that an umbrella would protect, and many umbrella carriers want to see assets or at least solid underlying limits first.
Mistake to avoid. Treating the lender's requirements as the coverage plan. A lender asks for collision and comprehensive to protect the car. It does not care what happens if she injures someone.
Household two: the new homeowner with young kids
The facts. Marcus and Priya have two children under 6, a $400,000 house with $60,000 of equity, $30,000 in savings, $45,000 in retirement accounts and a combined income of $115,000. One minivan, one sedan.
What a judgment can reach. More than they might think. Home equity may be partly protected by their state's homestead exemption; those exemptions range from small to very large depending on the state, which is why state car insurance requirements lookup and a local attorney matter. Savings and non-retirement investments are generally reachable. Retirement accounts in employer plans have strong protection under federal law (ERISA's rule that pension plan benefits may not be assigned or alienated), but protection for IRAs differs by state.
What a bad crash looks like. A rear-end collision with a van of four people, two seriously injured. Per-person limits are used up by each injured person, and the per-accident limit caps the total. That is why the middle number in 100/300/100 matters as much as the first.
Where the limits land. 100/300/100 is the minimum sensible tier for them; 250/500/100 is worth pricing because their household is both asset-bearing and growing. An umbrella of $1 million becomes worth pricing too. The cost of a $1 million umbrella is often a few hundred dollars a year; Progressive's umbrella cost page cites an ACE report putting the average at $383 a year for a household with one home, two cars and two drivers, and cost varies by carrier, state and driving record.
A wrinkle. Their own children are covered by the liability policy in a narrower way than other people. Many policies exclude injuries to family members, or limit them to the state minimum, and the rules vary by state. See can passengers and family members claim on your liability coverage?.
Household three: the high-earning single professional
The facts. Simone is 38, earns $240,000, owns a condominium with substantial equity, has a $400,000 brokerage account and drives an SUV about 12,000 miles a year. No dependents.
What a judgment can reach. Her income is the biggest asset. A plaintiff's lawyer can see it in a few minutes of research. A court judgment is not the same as a payout, but a large verdict against someone with a high income and visible assets is more likely to be pursued, and more likely to be settled at the policy limit.
What a bad crash looks like. She injures a 40-year-old with a spinal injury who cannot return to work. Economic damages (lifetime lost earnings and medical care) plus pain and suffering produce an amount many times a $100,000 limit. See pain and suffering: how noneconomic damages are valued and capped for how that second part is valued.
Where the limits land. 250/500/100 as the auto base, plus an umbrella sized to her net worth and income, commonly starting at $1 million and moving up from there. The reason to go to the higher auto tier first is that most umbrella carriers set underlying-limit requirements. Commonly they ask for something like 250/500/100 on the auto policy and a stated minimum on the home policy, though the exact figures vary by carrier, so ask for the list before quoting.
Mistake to avoid. Buying the umbrella and forgetting to raise the underlying limits. If the umbrella requires 250/500 and the auto policy carries 100/300, the gap between the two is a coverage hole she has to fill herself.
Household four: the retiree with a paid-off house
The facts. Walter is 71, widowed, owns a house worth $350,000 outright, holds $380,000 in an IRA and receives $3,200 a month from Social Security and a pension. He drives 5,000 miles a year.
What a judgment can reach. The house, subject to his state's homestead rules; the IRA, to the extent that his state does not protect it; any bank savings. Social Security benefits are in a different category. Under 42 U.S.C. 407, those payments are not subject to execution, levy, attachment, garnishment or other legal process. That is a real protection, but it covers only that income, not the house, the IRA or the savings. Median net worth for ages 65 to 74 was roughly $410,000 in the Federal Reserve's 2022 survey, so Walter's situation is typical of a retiree who has built wealth in a house and an account rather than in cash.
What a bad crash looks like. Fewer miles means fewer crashes, but older drivers face higher injury risk in a crash and may have vision, reaction or medication issues. A left-turn crash with a family minivan is a plausible serious claim. At his age, a judgment would also be paid from assets he cannot easily rebuild. See protecting retirement savings from an auto liability judgment for the retiree-specific version of this analysis.
Where the limits land. 250/500/100, and a $1 million umbrella is the next consideration. His low mileage may make the premium for higher limits lower than he fears. He should also ask whether an umbrella will cover him and any household members who drive, and whether it applies if a grandchild borrows his car (see lending your car: owner liability and negligent entrustment).
Mistake to avoid. Cutting liability limits to save money in retirement because "I am a careful driver." The cost of liability limits is mostly a function of exposure to loss, not of how careful he is. Collision and comprehensive deductibles are better places to trim.
Household five: the family with a teen driver
The facts. Alex and Jordan earn $130,000 combined, own a home with $150,000 in equity, and just added their 16-year-old to the policy. Three cars, one new driver.
What a judgment can reach. In most states, parents face some form of liability for a minor's driving, ranging from owner liability for the family car to statutory rules about a parent who signs the minor's license application. That varies widely; see are parents legally liable for a teen's car crash?. Practically, if the teen causes a serious crash in the family car, the plaintiff's lawyer will name the teen, the parents and the car's owner, and the family assets are in play.
What a bad crash looks like. The teen is driving friends home at night. Three passengers in the teen's car and two in the other car are injured. The per-accident limit is stretched across five claimants, and the passengers in the teen's car are not guaranteed to be treated the way the family expects. See how insurers split limited coverage among several injured claimants.
Where the limits land. 250/500/100 is where this household usually ends up, and an umbrella of $1 million or more deserves a quote. Some umbrella insurers ask for teen drivers to be listed, may want a driver's license history, and may price the umbrella higher or require higher underlying limits for a household with a new driver, so ask early. The months after a teen starts driving are when the premium is highest, and also when the family has the most reason to look at the limit.
Mistake to avoid. Assuming the teen's risk is covered by simply listing them. Listing them gets them covered. It does not mean the limit is high enough for the claim size.
The five side by side
| Household | Main exposure | Reasonable tier to price (example) | Umbrella? |
|---|---|---|---|
| Renter with a car loan | Future wages | 50/100/50, consider 100/300/100 | Not yet |
| New homeowner with young kids | Home equity, savings, growing family | 100/300/100, price 250/500/100 | Price a $1 million |
| High-earning single professional | Income and investments | 250/500/100 | Yes, sized to net worth |
| Retiree with a paid-off house | House, IRA, savings | 250/500/100 | Price a $1 million |
| Household with a teen driver | Family assets, multi-claimant crash | 250/500/100 | Price $1 million or more |
These are starting points for a conversation with an agent, not answers. The point of the table is the pattern: the more there is to reach, and the more people that can be hurt at once, the higher the tier.
When an umbrella is cheaper than raising auto limits
Auto insurers price higher limits with factors that rise more slowly than the limit, so the first step up from the minimum is the best value. Further up, many insurers stop offering auto limits above 500/500 or a $1 million combined single limit, and the next layer is cheaper to buy as an umbrella. An umbrella of $1 million typically costs a few hundred dollars a year, according to published estimates, while an umbrella carrier that requires 250/500/100 underneath will often tell you to raise your auto limits first.
A useful rule is to compare three quotes:
- Your current limits.
- The auto limit the umbrella carrier requires underneath.
- The same plus a $1 million umbrella.
Quote 2 minus quote 1 is the price of the underlying step. Quote 3 minus quote 2 is the price of the umbrella itself. If the second number is small compared with the extra protection, the umbrella is the better value per dollar. See umbrella insurance: liability protection above your auto policy and adding an umbrella policy to your auto bundle: what it requires.
State exemptions: the same crash, different exposure
Two households with identical assets can face different risk because of where they live. States set their own rules for how much home equity is exempt, which retirement accounts are protected, whether a tenancy-by-the-entirety deed shields a home from one spouse's creditors, how long a judgment lasts and at what interest rate. A few states protect a primary home heavily; many protect only a modest amount. The federal wage garnishment cap above sets a ceiling on garnishment but states can be stricter. Nobody should rely on a general rule here. A lawyer who handles creditor-debtor law in your state can describe your actual exposure, and your state insurance department can answer questions about the coverage side.
Revisiting the choice at life events
Review your limits when any of these happens:
- You buy a home, or your equity grows by a large amount.
- A child is born, or a teen starts to drive.
- Your income rises sharply, or you inherit money.
- You start a side business or work that uses your car (which may need commercial coverage).
- You retire, downsize or move to a new state.
- You add a vehicle, such as a pickup, or start lending your car to relatives.
- Your state raises its minimum limits, which changes what the "floor" is.
An hour spent re-quoting at renewal is the cheapest part of this process.
Common questions
If I have no assets, do I need more than the minimum?
Probably yes. A judgment can reach future income, and the minimum limits in many states are lower than a single serious injury claim. Your assets today are a poor guide to your exposure over the next ten years.
Does a higher limit make me a target for lawsuits?
Claimants sue because they were hurt and the facts support a claim, not because of the number on a declarations page. Whether and when your limit is disclosed to the other side depends on the state and the stage of the claim. The practical effect of a higher limit is that more of a large claim is paid by the insurer instead of by you.
Are there cases where the state minimum is enough?
Sometimes, for a household with very little income or assets that is required to carry only the minimum to register a car. Even then, the added cost of a step up is worth pricing. Whether to go higher is a personal decision; this article cannot make it for you.
Does the umbrella cover everything my auto policy does?
No. An umbrella generally pays above your underlying limits for covered liability, and it has its own exclusions. It does not replace collision or comprehensive coverage, and it may not cover business use or intentional acts. Read the policy.
How often should I recheck the limits?
At every renewal, and at the life events listed above. Insurers and states change their rules too, and a limit that was generous five years ago may be thin today.
Key takeaways
- Choose liability limits by asking what a judgment could reach now and later, not by copying the state minimum or a friend's policy.
- Future income is an asset in a lawsuit. Federal law caps ordinary wage garnishment, but the cap is a ceiling, not immunity.
- Households with a home, savings, a high income or a teen driver commonly price 250/500/100, and an umbrella above it once the auto limit tops out.
- Raise your underlying auto limits to meet the umbrella carrier's requirement, or you will be left with a gap.
- State exemptions for homes and retirement accounts differ widely; ask an attorney in your state, and revisit your limits at each major life event.
