Your auto policy might top out at $100,000 per person — but one serious accident can trigger a $500,000 court judgment. The gap between your policy limits and the judgment comes straight out of your savings, your home equity, and sometimes your future wages. Umbrella insurance is the cheap extra layer that catches that overflow.

So how much do you actually need? Answer three quick questions — your net worth, whether you own a home, and the risk factors in your household — and this free calculator gives you a recommended umbrella coverage amount for 2026 plus an estimated annual premium range. It takes less than a minute.

How we estimate

This tool applies the most common advisor rule of thumb for umbrella insurance, transparently:

Recommended coverage = round-up-to-next-$1M(net worth) + $1M if you own a home + $1M per risk factor

Premium estimate: the first $1 million of umbrella coverage typically costs roughly $150–$350 per year; each additional $1 million usually adds about $75–$150 per year. The tool starts at $275 for the first million, adds $100 per extra million, then adjusts up for households with risk factors (×1.1 with one, ×1.25 with two or more) and shows the result as a ±25% range, since pricing varies widely by insurer and state.

Estimates only — not an insurance quote or financial advice. This tool produces a rough planning estimate from a common rule of thumb and approximate premium data. Your actual need and premium depend on your assets, claims history, state, insurer and underlying policy limits. Talk to a licensed insurance agent before buying an umbrella policy.

Frequently asked questions

How much umbrella insurance do I need?

A common rule of thumb is to carry at least as much umbrella coverage as your net worth — the total value of everything you own minus what you owe. Policies are sold in $1 million increments, so you round your net worth up and add $1 million more if you own a home, have a teen driver, a pool or a dog. The calculator above applies exactly this method and caps typical recommendations at $5 million.

What does umbrella insurance cost?

Umbrella insurance is one of the cheapest forms of protection. A first $1 million of coverage typically costs roughly $150 to $350 per year, and each additional $1 million usually adds only about $75 to $150 per year. Your driving record, risk factors and the insurer you choose move the price within that range.

Do I need umbrella insurance if I do not own a home?

Maybe. Umbrella coverage is not just for the wealthy — a serious at-fault car accident can produce a judgment of several hundred thousand dollars, and a court can reach future wages, not just current assets. Renters with teen drivers or significant savings can also benefit, though homeowners with more assets at risk are the most common buyers.

What do insurers require before they sell me umbrella coverage?

Almost every insurer requires you to raise your underlying auto and home liability limits first — typically 250/500/100 on auto ($250k per person, $500k per accident, $100k property) and $300,000 on homeowners. Those underlying limits must pay out before the umbrella layer kicks in.

Shopping for umbrella coverage? It is usually cheapest bundled with the insurer that already covers your home and cars — and most carriers require those underlying policies (or equivalent limits) anyway.
