Know what this estimate is based on
- Jurisdiction
- United States — state-regulated insurance
- Scope and limitations
- Educational estimate only. Insurance in the U.S. is regulated state by state, so rates, required coverages and available discounts differ by where you live. Your premium is set by an insurer's own underwriting — driving record, claims history, credit-based insurance score where permitted, the property itself — and only a quote is binding. What a policy pays depends on its exclusions and limits, not on this estimate.

How to use
- 01
Enter your net worth — everything you own, less what you owe.
- 02
Enter your annual income and how many years of it a judgment could realistically reach. Future wages can be garnished, which is why they belong in the exposure.
- 03
Open Advanced options and enter the liability limits your home and auto policies already carry.
- 04
Read the recommended coverage, then the rounded figure — umbrella policies are sold in whole millions.
- 05
Take that figure to your existing insurer first. Umbrella coverage is usually cheapest bought alongside the home and auto policies it sits above.
Formula
Recommended coverage = net worth + (annual income x the years of future earnings you want protected) − the liability limits you already carry. Umbrella policies are sold in whole millions, so the result is also shown rounded up to the next million, which is what you would actually buy. Future income is included because a judgment is not limited to what you own today: in most states wages can be garnished for years afterward, so someone with modest assets and a long career ahead can have a larger exposure than their balance sheet suggests. The tool sizes the limit, not the premium — and the premium for this coverage is small enough that rounding up is usually the cheap decision.
Example
A household with $600,000 of net worth and $95,000 of annual income, wanting ten years of earnings protected, carrying no umbrella today. Step 1 — Assets at risk: $600,000. Step 2 — Future income at risk: $95,000 x 10 = $950,000. Step 3 — Total exposure: $600,000 + $950,000 = $1,550,000. Step 4 — Subtract existing umbrella coverage: none, so the recommendation stands at $1,550,000. Step 5 — Round to what is sold: $2,000,000. At roughly $150 to $300 for the first million and $75 to $100 for the second, that is about $250 to $400 a year — the cheapest coverage in this whole category, protecting the largest single number on the page. Note what the home and auto policies would have paid on their own: a $300,000 auto liability limit against a $1.2 million judgment leaves $900,000 to be found from savings and future wages.
Definitions
- Umbrella policy
- Personal liability coverage that sits above your home and auto limits and pays when those are exhausted.
- Underlying limits
- The home and auto liability limits an umbrella carrier requires before it will write over them — commonly $300,000 and $250,000/$500,000.
- Liability
- What you legally owe someone else for injury or damage you caused. Distinct from coverage for your own losses.
- Judgment
- A court's award against you. It can be collected from assets and, in most states, from future wages.
- Garnishment
- Collecting a judgment directly from your paycheck, which is why future income belongs in the exposure this calculator measures.
- Duty to defend
- The insurer's obligation to fund your legal defense, normally in addition to the policy limit rather than out of it.
- Exclusion
- Something the policy does not cover — business activity, intentional acts, and often certain dogs, vehicles or rentals.
- Attractive nuisance
- A feature on your property likely to draw children, such as a pool or trampoline. It raises liability exposure and sometimes the premium.
- Split limits
- Auto liability written as per-person and per-accident amounts, such as $250,000/$500,000.
- Excess liability
- Coverage that extends underlying limits without adding new categories. An umbrella does both — it extends and it broadens.
- Personal injury coverage
- The umbrella's cover for libel, slander and similar claims that home and auto policies generally exclude.
- Net worth
- Everything you own less everything you owe. The starting point for sizing liability coverage, but not the whole exposure.
Good to know
What an umbrella policy is, and what it is not
An umbrella policy pays liability claims after your home and auto liability limits are exhausted. If a court awards $1.2 million and your auto policy caps at $300,000, the umbrella pays the remaining $900,000. It also broadens as well as extends: personal injury claims such as libel, slander and false arrest are typically covered by an umbrella and excluded by the policies underneath it. What it is not is coverage for you. It pays what you owe other people. Your own injuries are your health plan's job, your own car is collision coverage, your own house is the homeowners policy. And it is strictly personal — business activity, including most side businesses run from home, is excluded, which is one of the most expensive assumptions people make about it.
Why future income belongs in the exposure
Most guidance says to carry umbrella coverage equal to your net worth, which understates the risk for anyone young. A judgment is not limited to what you own on the day it lands. In most states, wages can be garnished for years afterward, and a large judgment can follow you for a decade or more. That makes a 32-year-old with $80,000 of savings and a thirty-year career ahead of them more exposed, in the only sense that matters, than a 65-year-old with the same savings and no earnings left. This calculator counts both: net worth plus the years of future income you choose to protect. Retirement accounts complicate it in the other direction — ERISA plans are strongly protected under federal law and IRAs to a large but capped amount, with state law varying beyond that. Do not treat those protections as absolute when sizing coverage.
Working through an example
Take a household with $600,000 of net worth and $95,000 of annual income, protecting ten years of earnings. Assets at risk: $600,000. Future income at risk: $95,000 times ten, or $950,000. Total exposure: $1,550,000. If they already carry no umbrella, the recommendation stands at the full $1,550,000, and since umbrella policies are sold in whole millions, the practical answer is $2,000,000. Price that: roughly $150 to $300 for the first million and $75 to $100 for the second, so about $250 to $400 a year. Now look at what the underlying policies would have done alone. Against a $1.2 million judgment, a $300,000 auto liability limit leaves $900,000 to be found from savings and future paychecks. That is the entire case for the coverage, and it costs less than most people spend on streaming subscriptions.
What the existing-limits field is really asking
The Advanced field asks what liability coverage you already carry — but it is worth understanding what an umbrella carrier does with that number, because it works differently from the way other coverage stacks. The carrier will not write over the top of thin underlying limits. Most require at least $300,000 of liability on the home policy and $250,000 per person and $500,000 per accident on auto before they will issue an umbrella at all. So raising those underlying limits is frequently part of the cost of buying the umbrella, not an alternative to it. The good news is that the increase is usually modest, and that going from $100,000 to $300,000 of auto liability is itself one of the better-value changes most drivers can make.
Keeping the coverage right over time
Umbrella coverage is set once and then quietly goes stale. Net worth grows, income grows, and the policy stays where it was. Re-check it after a promotion, a house purchase, an inheritance, or anything that changes what a court could reach. Also re-check it after anything that changes your risk rather than your balance sheet: a teenage driver joining the policy, a pool or trampoline going in, taking in a rental — including short-term listings — or getting a dog whose breed appears on carrier exclusion lists. Tell the carrier about all of it. An undisclosed rental or an unlisted driver is a coverage argument at the worst possible moment, and the whole value of this policy is that it holds when the number is large.
Frequently asked questions
What does umbrella insurance actually cover?
Liability beyond the limits of your home and auto policies. If a court awards $1.2 million after an accident and your auto policy caps at $300,000, the umbrella covers the difference. It also covers some things the underlying policies exclude, such as libel, slander and false arrest.
How much does it cost?
Less than people expect — commonly $150 to $300 a year for the first million, and roughly $75 to $100 for each million after that. Claims that large are rare, which is exactly why the coverage is cheap and why carrying too little is a poor trade.
Do I need it if I am not wealthy?
Wealth is not the only test. A judgment can reach future wages through garnishment, which puts anyone with a steady income and decades of working life ahead of them at risk. Teenage drivers, a swimming pool, a dog, rental property or a boat all raise the odds enough to matter.
How much coverage should I carry?
At least your net worth, and more if a large share of your exposure is future income. The common guidance is net worth plus a few years of earnings, rounded up to the next million — which is what this calculator does.
Will my insurer require anything first?
Yes. Umbrella carriers normally require underlying liability limits — typically $300,000 on the home policy and $250,000/$500,000 on auto — before they will write over the top. Raising those limits is part of the cost of the umbrella.
Does it cover my business?
No. A personal umbrella excludes business activity, including most side businesses run from home. A business needs commercial liability coverage; assuming otherwise is a common and expensive mistake.
What about renting out a room or a property?
Landlord activity is often excluded or needs to be scheduled specifically. Tell your carrier about any rental, including short-term listings — an undisclosed rental is a claim denied at the worst possible moment.
Does it pay my legal costs?
Usually yes, and this is underrated. The duty to defend generally sits outside the policy limit, so the carrier funds the lawyers without eating into the coverage. Defense costs alone can run into six figures on a case that never reaches a verdict.
Does an umbrella cover my own injuries or property?
No. It is liability coverage only — it pays what you owe others. Your own medical bills and your own damaged property are the job of health, auto and homeowners coverage.
Are retirement accounts at risk in a judgment?
Federal law protects most ERISA-qualified plans strongly, and IRAs to a large but capped amount; state law varies considerably beyond that. Do not treat the protection as absolute when sizing coverage — it differs by state and by account type.
Does it cover an at-fault accident by my teenage driver?
Yes, if they are a listed household driver on the auto policy the umbrella sits above. Teenage drivers are among the most common reasons families buy one in the first place.
Is a million enough?
For many households, yes. But the figure to test against is not your assets today — it is your assets plus the wages a court could reach for years afterward. That is why this calculator counts future income rather than net worth alone.
