Excess Liability Tool

How Much Umbrella Insurance Do You Need?

Most coverage reviews compare limits. This one shows you the band between them — the gap where your umbrella has not attached yet and your primary policy has already run out.

$2,500,000

Your umbrella would not reach your underlying coverage. A typical carrier requires $500,000 underlying before an umbrella attaches. At your current limits there is an uninsured band of up to $200,000 that you would pay yourself before the umbrella responds.

Above the top of your tower, $1,000,000 of net worth sits outside any liability policy.

Illustrative structure only — not a quote, and not coverage or legal advice. This tool performs arithmetic on the figures you enter; it does not price policies or reflect any specific carrier's underwriting. Underlying limit requirements vary by carrier and by policy; the $500,000 figures used here reflect requirements common among private-client carriers. Umbrella policies also carry exclusions — business activities in particular — that a limit comparison does not capture.

The gap most households never see

An umbrella policy is not a bigger version of your auto or home liability coverage. It is a separate layer that sits above them, and it only begins paying at a specific figure the carrier sets — the attachment point.

When your underlying limits meet that figure, the layers touch and the tower is continuous. When they do not, there is a band in the middle that neither policy covers. A household carrying $100K/$300K auto limits under an umbrella that requires $500,000 has a $200,000 uninsured band sitting directly in the path of the exact claim the umbrella was purchased to handle.

This is rarely anyone's error in the moment. Primary policies and umbrellas are often bought years apart, sometimes through different agents, and carriers revise their underlying requirements at renewal. The tower drifts apart quietly, and the gap is typically discovered during a claim.

The number above your tower matters too. Liability judgments can reach assets no policy is standing in front of — which is why the exposed band in the illustration is measured against net worth rather than against your current limits.

What this tool deliberately does not do

  • It does not price anything. No premium shown, no carrier contacted, no rate applied.
  • It does not surface exclusions. Business activities, board service, rental property, and watercraft are common umbrella exclusions that a limit comparison cannot reveal.
  • It does not know your carrier's actual requirements, which vary and can change at renewal.

It is meant to make one specific structural problem visible, so it can be asked about directly.
