How Much Personal Liability Coverage Do I Need?

To decide how much personal liability coverage you need, add up the assets a court judgment could reach, add a realistic share of the income a creditor could garnish, then add a buffer for defense costs and household risk. That total is your minimum policy limit. For most households with meaningful home equity or savings, the answer lands above the $100,000 default on a homeowners policy and often calls for a $1 million umbrella on top.

Add Up the Assets a Judgment Could Reach

Start with what a plaintiff’s attorney could actually collect on. Home equity is usually the largest line: current market value minus the mortgage balance. Then add checking and savings, taxable brokerage accounts, other real estate equity, vehicles, valuable personal property, and business interests. That sum is your starting exposure.

Subtract what the law puts out of reach. Employer-sponsored retirement plans governed by ERISA, including 401(k)s and pensions, are shielded from creditors in civil lawsuits and bankruptcy.¹ Traditional and Roth IRAs carry separate federal bankruptcy protection up to roughly $1,512,350, adjusted every three years.

Homestead Exemption

Nearly every state protects some portion of your primary residence’s equity from a civil judgment. Amounts range from no specific exemption in a few states to unlimited protection in roughly seven states and the District of Columbia, with most states falling between $25,000 and $500,000. Look up your state’s figure and subtract it from your exposed home equity. The exemption does not block mortgage lenders, tax liens, or child support.

Joint Ownership

In about half the states, married couples can hold property as tenants by the entirety. When a judgment names only one spouse, a creditor cannot reach property held this way. The protection ends if the debt is joint or if one spouse dies. If your home or accounts are titled this way and only you are being sued, those assets may fall outside your exposed total.

Add the Income a Creditor Could Take

A judgment that exceeds your assets does not stop there. Federal law lets a creditor garnish the lesser of 25% of your disposable earnings per pay period or the amount by which your weekly disposable earnings exceed 30 times the federal minimum wage of $7.25 per hour, which works out to $217.50 per week.² Earn more than $290 per week in disposable income and a creditor can take the full 25% of each paycheck until the judgment is paid.³

Civil judgments stay enforceable for about 10 years in most states, and many states let plaintiffs renew them, so a large judgment can shadow your paychecks for 20 years or more while interest keeps accruing. For someone earning $100,000, 25% garnishment over 10 years is $250,000 in lost wages on top of whatever assets were seized. Project five to ten years of your income, take 25%, and add that number to your coverage target.

Add a Buffer for Household Risk

Certain features of your household make a claim both more likely and more expensive. If any of these apply, your target should include a buffer above the raw asset-plus-income figure.

Swimming pools and trampolines fall under the attractive nuisance doctrine, which can hold property owners liable when children are hurt by a hazard on the property, including trespassing children. Drowning and spinal injury verdicts routinely reach six or seven figures.
Roughly 36 states impose strict liability for dog bites, so the owner pays damages regardless of whether the dog has ever shown aggression. Other states follow a one-bite rule tied to prior knowledge. Settlements frequently top $50,000.
A newly licensed driver in the household sharply raises accident exposure, and a serious collision can produce judgments in the hundreds of thousands.
Rental property creates landlord liability for tenant and guest injuries. Your homeowners policy on your primary residence will not cover incidents at a rental, so separate landlord coverage is required.
Entertaining with alcohol raises the odds of a premises liability claim if a guest is hurt on your property or causes harm after leaving.

If one of these applies, add 20% to your subtotal. If two or more apply, 30% to 50% is a reasonable adjustment. Legal defense alone can run $50,000 to $100,000 or more in a serious injury case, and those costs come out of your policy limit before any payout to the plaintiff.

Match the Number to a Policy

Homeowners and Renters Liability

Most homeowners and renters policies offer personal liability in standardized tiers of $100,000, $300,000, and $500,000.⁴ The $100,000 level is the common default. Moving from $100,000 to $300,000 often costs less than $50 a year, which makes it one of the cheapest upgrades available for anyone whose calculation lands above the default.

Auto Liability

Every state except New Hampshire sets a minimum auto liability requirement, with mandated per-person bodily injury limits running from about $10,000 to $50,000.⁵ A common floor is 25/50/25: $25,000 per injured person, $50,000 per accident, and $25,000 for property damage. A single emergency-room visit after a crash can wipe out the $25,000 per-person limit, leaving your assets exposed. Industry guidance generally points to at least $100,000/$300,000 for bodily injury and $100,000 for property damage, with higher limits if your net worth or earnings warrant it.

Umbrella Coverage

When your target exceeds what you can buy on a base policy, an umbrella sits on top of your homeowners and auto coverage and pays once those underlying limits are exhausted. Umbrella policies start at $1 million and go up in $1 million increments, with some carriers offering $5 million or $10 million. Insurers typically require you to carry at least $250,000/$500,000 on auto liability and $300,000 on homeowners liability before writing one.

A $1 million umbrella usually costs $150 to $400 a year when bundled with your home and auto policies, and each additional million adds roughly $75 to $150. If your calculation points to $1.5 million or more, an umbrella is almost always cheaper than pushing base limits that high. Some umbrellas also provide drop-down coverage for a few claim types that your base policies exclude, which raising the base limit will not fix.

Where a Higher Limit Will Not Help

Personal liability coverage pays for accidents, not everything that could cost you money. An excluded claim hits your assets no matter how high your policy limit runs.

Intentional acts are not covered. Courts read “intentional” to mean you meant the harm, so reckless or negligent conduct can still be covered even when it was not purely accidental.
Business activities, including a home-based side business, are excluded from personal homeowners and renters liability. A client who trips on your stairs during a home office visit is a business claim, and separate business or professional liability insurance is what covers it.
Cars, boats above a certain size, and aircraft are excluded. Auto insurance handles vehicle liability; boats and aircraft need their own policies.
Defamation, libel, slander, false arrest, and invasion of privacy fall outside standard coverage unless you add a personal injury endorsement to your homeowners policy.

Read your declarations page and exclusion list before you settle on a limit. If an exclusion overlaps with a real risk in your life, close that gap with a separate policy or endorsement rather than buying more of the same coverage.

A Worked Example

Say you own a home worth $400,000 with a $250,000 mortgage, leaving $150,000 in equity. You have $100,000 in a taxable brokerage account, $30,000 in savings, and a $20,000 car. Your 401(k) holds $200,000, and your state’s homestead exemption shields $50,000 of home equity.

Assets subject to judgment: $150,000 + $100,000 + $30,000 + $20,000 = $300,000.
Less the homestead exemption: $300,000 − $50,000 = $250,000 exposed. The 401(k) is fully protected under ERISA and does not enter the calculation.¹
Future earnings at risk: $90,000 annual income × 25% × 10 years = $225,000.²
Subtotal: $475,000.
Risk buffer for a dog and a pool: 30%, or $142,500.
Coverage target: about $620,000.

A $500,000 homeowners liability limit plus a $1 million umbrella clears the target and extends over auto liability as well. A household with fewer risk factors might land closer to $400,000 and get there on a $500,000 base policy alone. Redo the calculation when your equity grows, your income changes, or a new risk factor enters the picture, such as a rental property or a teen driver.
