The rule of thumb, and why it’s only a starting point
The standard guidance is that umbrella coverage should be at least equal to your net worth. For a household with meaningful equity, that number climbs fast, which is exactly why high-net-worth families commonly carry $3 million to $10 million in umbrella coverage, sometimes $25 million or more, well above what a standard auto or home policy’s built-in liability limit provides.
It’s also cheaper than most people expect. A first $1 million of umbrella coverage typically runs $300 to $500 a year, with the average closer to $380 for $1 to $2 million, and the cost per additional million drops from there. Relative to what’s actually at risk, an Ohio homeowner with a pool, a boat, a rental property, or a teenage driver in the house is paying very little to close a very large gap.
Where the gap actually shows up
Your homeowners and auto policies each carry a liability limit, usually $300,000 to $500,000. That’s the ceiling on what they’ll pay if you’re found liable for someone else’s injury or property damage. A serious accident, a lawsuit after a pool party, an injury on your property, can exceed that ceiling without much difficulty. Once it does, the umbrella policy picks up where the underlying policy stops, and without one, the difference comes directly out of personal assets.
Ohio-specific liability exposures we see most often
- Pools and ponds: attractive nuisance liability doesn’t require the injured party to be invited.
- Watercraft on Ohio lakes: Lake Erie and the state’s larger inland lakes carry their own liability considerations separate from auto and home policies.
- Domestic staff: household employees introduce workers’-comp-adjacent liability many homeowners don’t realize they’re carrying.
- Rental and investment property: a landlord’s liability exposure is distinct from, and usually not covered by, a primary-residence policy.
- Teen drivers: the single most common reason umbrella claims get triggered in practice.
- Board seats and executive roles: personal liability exposure that follows you outside the home entirely.

How we size it
We start from net worth, not a flat default number, then adjust for the specific exposures above. A household with a pool, a lake house, and a teenage driver needs a different umbrella limit than a household with none of those, even at identical net worth. This is one of the pieces we walk through during the full asset review, alongside dwelling and valuables coverage, since liability sized in isolation from the rest of the picture tends to be either wrong or expensive for no reason.
Umbrella insurance is the cheapest coverage most high-net-worth households own, and the one most likely to be sized wrong.
