An umbrella liability policy sits on top of auto and homeowner's liability, extending coverage beyond their limits. It is cheap — often $200–$400 a year for a million dollars of additional coverage — and it is the correct policy for any household with meaningful net worth or a public profile that could attract litigation.

The layering
In a lawsuit exceeding auto or homeowner's liability limits, the umbrella policy fills the gap up to its own limit. Coverage typically starts at $1 million and rises in increments. The underlying auto and homeowner's policies must meet minimum limits set by the umbrella carrier, which is why raising auto to $250/$500 often precedes buying the umbrella.
The right limit
A common rule is to hold umbrella coverage at least equal to net worth. Higher-net-worth households often hold $5 million or more; $1 million is the entry level. The premium curve is flat — the second million costs roughly the same as the first.
- Layer above auto and homeowner's.
- Cheap coverage for large marginal exposure.
- Hold at least equal to net worth as a starting rule.
