Estimate your umbrella liability premium
Free umbrella insurance calculator. Estimate your annual umbrella liability premium based on coverage amount, vehicles, and properties.
Estimate only · not a real quote
Choose a coverage amount and enter how many vehicles and properties you insure to get an instant, illustrative estimate of what umbrella liability insurance might cost per year. This tool is meant to give you a starting number before you talk to your auto or home insurer.
Umbrella insurance is priced with strong economies of scale: the first million dollars of coverage carries the highest per-dollar cost, because it is the layer most likely to actually be used in a serious liability claim, while each additional million costs progressively less because it is progressively less likely to be reached. This calculator uses an illustrative tiered cost table — a base cost for the first $1,000,000 of coverage (representative of the commonly cited $150–$350 per year range for a single-million policy), then smaller, decreasing per-million costs for $2,000,000 through $10,000,000 of total coverage.
On top of the coverage-tier base cost, the calculator applies a small illustrative risk adjustment for the number of vehicles and properties you enter, since umbrella coverage sits on top of your underlying auto and home policies and insurers generally charge more to extend excess liability across more underlying risks. The baseline assumes 2 vehicles and 1 property; each additional vehicle or property above that adds a modest percentage surcharge in this model.
This calculator does not use any real insurer’s rate filing, your claims history, your state, your net worth, or the specific limits on your underlying auto and home policies — all of which materially affect real umbrella pricing and, in most cases, whether you even qualify (insurers typically require minimum underlying liability limits before they will write an umbrella policy at all).
Umbrella insurance is excess liability coverage that sits on top of your existing auto, homeowners, or renters policy limits. If you are found liable for an injury, property damage, or certain lawsuits — such as libel or slander — and the judgment exceeds your underlying policy’s liability limit, umbrella coverage pays the difference up to the umbrella policy’s own limit, rather than the excess coming out of your personal assets.
Most insurers require you to carry minimum liability limits on your underlying auto and home policies (commonly $250,000/$500,000 for auto and $300,000 for home) before they will sell you an umbrella policy, since the umbrella is designed to activate only after those underlying limits are exhausted. Umbrella policies are often sold in $1,000,000 increments and can typically be added by the same insurer that writes your auto or home coverage.
A common rule of thumb is to carry umbrella coverage at least equal to your net worth, since that is roughly what a large liability judgment could put at risk. This calculator does not calculate a recommended amount — it only estimates the cost of an amount you choose.
Relative to the amount of coverage it provides, no — a first $1,000,000 of umbrella coverage is often surprisingly affordable compared to the liability limits on a standalone auto or home policy, because it only activates after your underlying coverage is exhausted.
Generally, yes. Insurers typically require you to carry and maintain specific minimum liability limits on your underlying policies as a condition of writing (and keeping) an umbrella policy.
Typically not for a business you own or operate — personal umbrella policies are generally designed for personal liability exposure (auto accidents, home injuries, certain personal lawsuits), not commercial activity, which usually needs separate commercial umbrella coverage.
Umbrella coverage extends excess liability across all of your underlying policies, so insurers generally charge more as the number of insured vehicles and properties grows, reflecting the larger number of ways a liability claim could arise.
Sometimes, through certain specialty umbrella carriers, but many insurers require the underlying policies to be written with them (or a partner company) as a condition of umbrella eligibility.
