# How Exposed Are You? (umbrellaexposure.com)

> Free, anonymous educational tools and sourced answers about personal umbrella liability insurance for households with significant assets: an exposure calculator (reachable assets plus the present value of future earnings, compared with the umbrella limit), a 1–100 umbrella readiness score, and short answers to common coverage questions. Not insurance, legal, or tax advice. No products are sold on the site; visitors can request a review by a licensed professional.

Last reviewed: 2026-10-10. Coverage statements cite the ISO personal umbrella form (DL 98 01) as analyzed by Rough Notes RNC-Pro and FC&S, IRMI, the NAIC, the Massachusetts Division of Insurance, and the Insurance Information Institute. Policy wording varies by insurer and state.

## Calculator method

- Exposed assets = (primary home equity − homestead protection) + other real estate equity + brokerage and cash + business interests + other assets.
- Future earnings (present value) = the sum, for each remaining working year y = 1 to N, of I × (1 + g)y−1 ÷ (1 + r)y, where I is current annual earned income, g is the income growth rate, and r is the discount rate.
- Total exposure = exposed assets + future earnings.
- Gap = the greater of zero and (total exposure − current umbrella limit).
- Rounded starting point = total exposure rounded up to the next $1 million, with a $1 million minimum.
- Defaults: income growth 2% (matches the Federal Reserve’s 2% longer-run inflation goal, FOMC statement reaffirmed Jan. 27, 2026) and discount rate 4% (a round-number assumption, not a market rate). Both are adjustable. Retirement accounts are not counted. Underlying home and auto limits are not counted, which keeps the estimate conservative.

## Readiness score (1–100)

Yes = full weight; No or Not sure = 0; N/A removes the item. Score = round(100 × earned ÷ applicable), between 1 and 100. Weights total 100:

1. The umbrella limit is at least equal to net worth, with future earnings considered. (weight 14, severity High)
2. Underlying liability limits meet the minimums the umbrella requires. (weight 12, severity High)
3. Every home, vehicle, and boat is scheduled as underlying insurance on the umbrella. (weight 11, severity High)
4. Trusts and LLCs that own property are named on the umbrella and the underlying policies. (weight 10, severity High, N/A allowed)
5. Watercraft are confirmed covered by size, length, and horsepower, or scheduled underneath. (weight 9, severity Medium, N/A allowed)
6. Teen and young drivers are listed on the auto policy and recognized by the umbrella. (weight 8, severity Medium, N/A allowed)
7. Household employees are addressed, including workers compensation and employment practices. (weight 7, severity Medium, N/A allowed)
8. Rental properties, including short-term rentals, are scheduled and covered. (weight 7, severity Medium, N/A allowed)
9. All underlying policies are in force, with no lapse planned for a renovation, vacancy, or sale. (weight 6, severity Medium)
10. Board service is covered by the organization’s D&O, or excess D&O is in place. (weight 5, severity Lower, N/A allowed)
11. Excess uninsured/underinsured motorist coverage is included or was deliberately declined. (weight 5, severity Lower)
12. Personal injury coverage (libel, slander, invasion of privacy) is included. (weight 3, severity Lower)
13. The program was reviewed in the last 12 months or after the last major life change. (weight 3, severity Lower)

Bands:
- 90–100: Well positioned (Requires no High-severity item answered No or Not sure; otherwise shown as “Solid, with gaps to close.”)
- 75–89: Solid, with gaps to close
- 50–74: Meaningful gaps
- 1–49: Significant exposure

## Questions

- [How much umbrella insurance do I need?](https://umbrellaexposure.com/questions/how-much-umbrella-insurance-do-i-need/): A common starting point is an umbrella limit at least equal to your net worth plus the future earnings a judgment could reach, less assets your state protects. Umbrellas are usually sold in $1 million increments, so round up. Then adjust for lifestyle risks such as teen drivers, a pool, boats, rental property, or household staff, and for the limits insurers will actually offer you.
- [How do I calculate my liability exposure (assets plus future earnings)?](https://umbrellaexposure.com/questions/how-to-calculate-liability-exposure/): Add the assets a judgment could reach: home equity not shielded by homestead law, other real estate, brokerage and cash, business interests, and other valuables. Add the present value of your future earned income over your remaining working years. Leave out assets your state generally protects, such as many retirement accounts. Compare the total with your umbrella limit. The difference is your gap.
- [Does an umbrella policy cover a home owned by a trust or LLC?](https://umbrellaexposure.com/questions/does-umbrella-cover-trust-or-llc-home/): Not automatically. A personal umbrella is written for individuals and their households, so a home titled to a trust or LLC can fall outside it unless the entity is added. For trusts, standard forms include a homeowners trust endorsement and a matching personal umbrella trust endorsement. LLC-owned property is harder: personal umbrellas commonly exclude business activities, so it may need commercial coverage instead.
- [Does an umbrella policy cover my boat or yacht?](https://umbrellaexposure.com/questions/does-umbrella-cover-boat-or-yacht/): Often only if the boat’s liability is insured underneath it. The standard ISO personal umbrella excludes watercraft liability except to the extent underlying watercraft coverage applies, and many insurer forms add length or horsepower limits. For a larger boat or yacht, the umbrella usually expects a watercraft or yacht policy with liability (protection and indemnity) at a required minimum, listed on the umbrella’s declarations.
- [What are underlying limits, and why do they matter for an umbrella?](https://umbrellaexposure.com/questions/what-are-underlying-limits/): Underlying limits are the liability limits your home, auto, watercraft, and similar policies must carry before the umbrella pays. The umbrella’s declarations list a required minimum for each. The umbrella pays only above those amounts, so if a policy carries less than required, you pay the difference yourself. Triple-I says most insurers want about $250,000 of auto liability and $300,000 of homeowners liability first.
- [Does an umbrella policy cover household employees?](https://umbrellaexposure.com/questions/does-umbrella-cover-household-employees/): Partly. A personal umbrella can respond to liability claims involving household staff, such as a guest hurt by something an employee did, but the standard form excludes injury to anyone who is, or should be, covered under a workers compensation or similar law. Injuries to the employees themselves usually belong under workers compensation. Employment disputes such as wrongful termination are commonly excluded or limited, so they may need separate employment practices coverage.
- [Does an umbrella policy cover a teen driver?](https://umbrellaexposure.com/questions/does-umbrella-cover-teen-driver/): Usually, if the teen is a resident relative and is listed on an auto policy that meets the umbrella’s underlying requirement. Personal umbrellas generally extend to household members. Problems arise when a teen drives a car that isn’t scheduled, a car titled in the teen’s own name or a business’s name, or when the auto liability limit is below the umbrella’s minimum. Triple-I lists a teenage driver as a reason to consider an umbrella.
- [Does a personal umbrella cover nonprofit board service?](https://umbrellaexposure.com/questions/does-umbrella-cover-nonprofit-board-service/): Sometimes, within limits. The standard ISO personal umbrella excludes liability for acting as a corporate or organization officer or director, except when the only compensation is reimbursement of expenses for a nonprofit organization. Many personal umbrellas therefore cover unpaid nonprofit board service but exclude paid or for-profit boards, and some limit certain claim types. The organization’s own directors and officers (D&O) policy is normally the first line of defense.
- [What is excess uninsured/underinsured motorist coverage?](https://umbrellaexposure.com/questions/what-is-excess-uninsured-underinsured-motorist-coverage/): Excess uninsured/underinsured motorist (UM/UIM) coverage extends UM/UIM protection above your auto policy’s limits. It pays for your own household’s injuries when an at-fault driver has no insurance or too little. The standard ISO personal umbrella does not provide it unless an endorsement is added, and availability varies by state and insurer, so it usually has to be requested specifically.
- [What happens to my umbrella if my homeowners policy lapses or is cancelled?](https://umbrellaexposure.com/questions/what-happens-if-underlying-policy-lapses/): The umbrella does not fill in for it. Under the standard ISO wording, you must keep the underlying insurance at the full limits shown, and if you don’t, the insurer will not be liable for more than it would have been had that coverage stayed in force. In practice, you pay the missing underlying layer yourself before the umbrella responds. Renovations, vacancies, and sales are common times for this to happen.
