How much liability and umbrella coverage do I need?

Liability coverage pays when someone is hurt on your property or you damage theirs, and it is the limit most households set once and never revisit. A serious injury suit can run past what a typical homeowners policy offers. The calculator adds up what a judgment could reach, then splits the answer between your homeowners liability limit and an umbrella policy.

How to use it

Enter four figures. Home equity is value minus the mortgage. Savings and taxable investments come from your statements. Retirement accounts are counted at only a share of their balance, which you set. Annual income matters because a judgment can reach future wages in many states. Then tick every exposure that applies: a pool, hot tub or trampoline; a dog; a teen or newly licensed driver; a rental or short-term rental property; a boat, jet ski, ATV or golf cart; or regular party hosting, coaching, board service or public posting.

How the math works

Assets at risk equal home equity, plus savings, plus the protected share of retirement accounts, plus two years of income. The target is the larger of $300,000 and that total rounded up to the next $100,000, and ticking two or more exposures lifts the target to at least $1,000,000. At $500,000 or less, the whole target is homeowners liability (personal liability, Coverage E). Above that, Coverage E is set at $300,000 and the shortfall, rounded up to the next $1 million, becomes an umbrella policy. The headline is Coverage E plus the umbrella.

Say, hypothetically, $250,000 of equity, $150,000 of savings, $300,000 in retirement accounts at the default 50% share, and $120,000 of income. Assets at risk are $250,000 + $150,000 + $150,000 + $240,000 = $790,000, so the target is $800,000. Coverage E is $300,000, the $500,000 shortfall rounds up to one $1 million umbrella layer, and the headline is $1.3 million. With two exposures ticked, even a household with half those assets lands on the same combination.

What it assumes

The $300,000 floor, the two years of income, the 50% retirement share, the $500,000 cutover and the $1 million layers are the tool's rules of thumb, not law and not any insurer's rating rule. The Insurance Information Institute reports that most insurers want about $250,000 of liability on your auto policy and $300,000 on your homeowners policy before they sell an umbrella (Triple-I, accessed October 2026). Each umbrella insurer sets its own required limits, so treat those figures as typical, not universal. Every dollar entry is an editable example.

Where it stops being right

What a creditor can actually reach depends on your state and on the type of account, so the retirement share and the income multiple are guesses an attorney can replace with facts. The tool also stops at the answer; it has no price. When assets round to something like $400,000, it shows that figure as the homeowners limit, but your insurer may offer only certain limits, so ask which.

An umbrella is not a cure-all. Business activities and intentional acts are generally excluded, and household drivers must be listed on the auto policy (Liability exclusions: what Coverage E won't pay). The ISO homeowners form (HO 00 03 05 11) provides a legal defense and pays claim expenses in addition to the Coverage E limit, but the duty to defend ends once a judgment or settlement uses the limit up. For the exposure checkboxes, read pools, trampolines and attractive nuisances and dog bites, breed lists and homeowners liability, and see umbrella insurance for homeowners: what it adds and where it stops for how the layers interact.
