When setting premiums, companies look at driving records, the number of cars you own and in some states, the driversâ€™ ages. Rates may also vary based on the general litigiousness where you live. If you had trouble getting auto or homeownerâ€™s insurance it might be a lot tougher to get a personal umbrella policy.
An idea of what you might pay annually for $1 million of umbrella liability protection is around $150 for a married couple with two cars, good driving records, and no underage drivers. Adding another car or an underage driver would increase the cost. An umbrella policy will automatically extend the coverage of your auto and homeowners policies but it costs extra to spread the umbrella over other policies such as boat insurance.
