The right coverage limit is the amount that would keep one bad day from wrecking your finances, not the cheapest amount that keeps you legal. For most households that means starting with your state's minimum, adding up what a lawsuit could reach (your home equity, savings, investments and future income), and then buying liability limits that sit comfortably above that minimum. Many advisors point to $100,000 per person and $300,000 per accident as a sensible floor for auto liability, with an umbrella policy on top once your assets outgrow it.
This guide shows you how to do that in order: what a limit is, what states require, how to size liability, when an umbrella makes sense, and how to keep premiums reasonable while you do it.
TL;DR
- A coverage limit is the most your insurer will pay for a covered loss. Once a claim goes past it, you pay the rest.
- State minimums are a legal floor, not a safety level. Regulators themselves suggest considering more than the minimum.
- Size liability limits to what you could lose: assets, income and risks such as teen drivers, a pool or rental property.
- An umbrella policy adds liability protection above auto and home limits, but it usually requires minimum underlying limits first.
- Raise limits where the loss would be ruinous. Keep deductibles and small-loss coverage lean where your savings can absorb the hit.

What a coverage limit actually is
Every liability policy has a ceiling. If you cause an accident and the other driver's medical bills and car repairs come to more than that ceiling, the insurer stops paying and the balance becomes your problem. That balance can be collected from your savings, investments and, in some cases, future wages.
Auto limits are usually written as three numbers. A 100/300/100 policy pays up to $100,000 per injured person, up to $300,000 for all injuries in one accident, and up to $100,000 for property damage. Some policies use a single combined limit instead, one number that covers injuries and property damage together.
Limits are different from deductibles. A deductible is what you pay before the insurer pays. A limit is where the insurer's payment ends. Mixing them up is the most common reason people feel "fully covered" and then are surprised by a claim. Our insurance glossary defines both in plain language.
Start with what your state requires
Almost every state sets a minimum. According to CNBC Select's 2026 state roundup, all states except New Hampshire require drivers to carry a minimum amount of liability insurance, and the amounts vary by state.
A few official examples show how much they differ:
| State | Bodily injury | Property damage | Source |
|---|---|---|---|
| Ohio | $25,000 per person / $50,000 per accident | $25,000 per accident | Ohio Department of Insurance |
| Kansas | $25,000 per person / $50,000 per accident | $25,000 per accident | Kansas Insurance Department |
| Maryland | 30/60/15 minimum | (the last number) $15,000 | Maryland Insurance Administration |
| Georgia | Single limit of at least $75,000 | Included | Georgia Office of Commissioner of Insurance |
Some states also require extras. Kansas, for example, requires personal injury protection (PIP) and uninsured/underinsured motorist coverage in addition to liability, per the same Kansas guide. Check your own state's insurance department for the current figures before you buy.
The key point is what regulators say about these numbers. Ohio's department calls them bare minimums and notes that a serious crash needs much more insurance. Kansas advises drivers to consider a policy that exceeds the state minimum. Treat the legal floor as the starting line.
How much liability coverage is enough
There is no universal number, but there is a reliable process. Regulators and extension programs describe the same logic: figure out what you could lose, how likely each risk is, and then decide which risks to insure and which to carry yourself. The University of Georgia Extension puts the test simply: insurance is a necessity when a loss could cause financial ruin, and more of a nuisance when current income or emergency savings could cover it.
Step 1: Inventory what a judgment could reach
List the following, with rough values:
- Home equity (value minus what you owe).
- Cash, savings and brokerage accounts.
- Other real estate, including rental property.
- IRAs and other retirement accounts that may not have strong creditor protection.
- Your future earnings, especially if you are in your peak earning years.
Ohio's insurance department notes that the value of your assets may help you decide how much coverage to carry. Employer plans such as 401(k)s are generally protected from civil liability under federal law and are often left out of the tally, while IRAs may be wise to include, according to Fidelity's umbrella guidance. Protection for retirement accounts varies, so ask a licensed attorney about your state.
Step 2: Add up your risk factors
Assets are only half the picture. Your lifestyle changes the odds that a claim lands on you. Fidelity lists homeowner or renter risks, causing an accident, and potentially dangerous activities as the exposures to weigh. In practice, these raise the stakes:
- A long daily commute or heavy highway driving.
- Teen or inexperienced drivers on your policy.
- A pool, trampoline, dog or frequent guests at home.
- Rental property or a side business.
- A boat, an ATV or other recreational vehicle.
Step 3: Match limits to the total
Use your inventory as a ceiling for what you want to protect. Many advisors suggest at least $100,000 per person and $300,000 per accident for auto liability, or an equivalent combined single limit. Common split limits run from 25/50/25 up through 50/100/50 and 100/300/100. Treat those as reference points, not a prescription.
Here is an illustration with made-up numbers. Suppose a family has $180,000 in home equity, $60,000 in savings and brokerage accounts, and two incomes. A 25/50/25 policy would leave nearly all of that exposed if one accident injured several people. Moving to 100/300/100 raises the protection a lot, and an umbrella could then cover anything above that. Your own numbers will differ, and a licensed agent can run them with you.
Step 4: Price the tiers side by side
The step-up from state minimum to higher limits is often smaller than people expect, because the first dollars of coverage carry most of the premium. The way to know is to price several tiers on the same policy. Asking for quotes at three levels, for example 50/100/50, 100/300/100 and a higher combined limit, shows exactly what each rung costs. We do that comparison across more than 25 A-rated carriers on our auto insurance page.
Coverage limits beyond auto
Homeowners and renters liability
Your home policy has a personal liability limit that pays if a visitor is hurt on your property or you damage someone else's. It also has a separate limit for your belongings. Both should reflect what you own today, not what you owned when you bought the policy. Our homeowners insurance page explains how those pieces fit together, and renters have the same liability exposure with a lower-cost policy.
The dwelling limit matters just as much. It should match what it would cost to rebuild, which is a different figure from market value. If your home has been renovated, or building costs have shifted, revisit it. Our guide on when to switch home insurance lists the signals that your current policy no longer fits.
Umbrella policies
An umbrella adds liability protection on top of your auto, home and similar policies. The Massachusetts Division of Insurance explains that umbrella and excess policies require underlying coverage listed on the declarations page and respond only when those primary limits are used up. If you let the underlying coverage lapse, those limits are treated as a deductible you pay yourself.
The Kansas Insurance Department describes umbrella coverage as an additional $1 million to $5 million above your primary auto liability. Insurers commonly require underlying auto limits in the range of $250,000 to $300,000, so umbrella shoppers usually raise their auto and home liability first.
A workable sizing approach is to cover the value of your taxable assets and any homes beyond your primary residence, then consider future income. Our umbrella insurance page shows how we help clients set that number.
Business coverage limits
Business owners face the same logic with more moving parts. Before choosing limits, map out where a claim could come from: customers on your premises, your products, your vehicles, your employees. A walk through business insurance types is a useful way to evaluate exposure and possible losses before you pick a number for each policy.
Know what a general liability policy leaves out. Per the Minnesota Department of Commerce, standard liability does not cover employment-practices claims, professional liability or errors and omissions claims, claims tied to operating a vehicle, or workers' compensation claims. Each needs its own policy and its own limit. Our business insurance team can map those gaps with you.
Balancing protection and price
The goal is not the highest limits on every line. It is high limits where a loss would be devastating and lean choices where it would not. The University of Georgia Extension warns that paying for coverage you do not need is a nuisance, just as being underinsured is.
A practical split:
- Raise the limit on liability (auto, home, umbrella), because one claim can exceed your net worth and the added premium is modest.
- Raise the deductible on small, predictable losses you could pay from emergency savings.
- Reconsider optional coverage on older vehicles. Our 10% rule for full coverage car insurance explains when collision and comprehensive stop paying off.
- Bundle where it genuinely lowers cost, and compare it against standalone pricing.
Revisit limits at least once a year and after big changes: a new home, a marriage, a baby, a teen driver, a promotion or an inheritance. Our page on the annual insurance review walks through what to look at, and the 30 minute policy review checklist shows the contract lines worth checking first.

FAQ
How much liability coverage do I need?
It depends on what you could lose. State minimums are the legal floor, and regulators say a serious crash can exceed them. Many advisors suggest at least 100/300/100 for auto, then an umbrella if your assets are larger than your combined limits. A licensed agent can size it to your numbers.
What is not covered by liability insurance?
Liability pays for harm you cause to others, not your own losses. For businesses, standard liability generally excludes workers' compensation, professional errors and omissions, employment-practices claims and vehicle-related claims, per the Minnesota Department of Commerce. Those need separate policies.
Do I need an umbrella policy if I already have high auto limits?
Possibly. An umbrella sits above auto and home limits and pays only after they are exhausted. If your assets and future income are larger than your highest primary limit, an umbrella extends protection at a relatively modest cost compared with raising every underlying limit.
How often should I review my coverage limits?
At least once a year, and after major life changes such as buying a home, adding a teen driver or starting a business. Values and risks shift, and limits that fit three years ago may now leave you exposed.
