  "summary": "Find the exposed net worth an umbrella policy needs to cover after underlying limits.",
  "description": "An umbrella policy sits on top of your auto and homeowners liability limits and kicks in once those underlying limits are exhausted, extending coverage in $1 million increments typically for a few hundred dollars a year. This calculator focuses specifically on sizing: it takes your net worth, future earnings you'd want protected from wage garnishment in a lawsuit, and your existing underlying liability limits, then shows the exposure gap an umbrella policy should close — different from a general 'how much umbrella should I buy' rule of thumb, this ties the number to your actual balance sheet plus a buffer for future income at risk in a large judgment.",
  "formula": "Assets at risk = net worth + (years of future income to protect × annual income × protection factor). Coverage gap = assets at risk − existing liability limits (auto + home combined, not stacked). Recommended umbrella = round up gap to nearest $1M increment.",

  "faq": [
    {
      "q": "Why does net worth matter more than income for sizing umbrella coverage?",
      "a": "In a lawsuit, a judgment creditor can generally go after non-exempt assets you already own more directly than future wages, which in many states have partial garnishment protections and practical collection limits. The bigger your net worth, the more there is to lose outright, which is why umbrella sizing usually starts from total assets, not income alone."
    },
    {
      "q": "Do umbrella policies require minimum underlying liability limits?",
      "a": "Yes. Insurers typically require you to carry at least $250,000–$300,000 in auto liability and $300,000 in homeowners liability before they'll write an umbrella policy, since the umbrella only pays after those underlying limits are exhausted, not from dollar one."
    },
    {
      "q": "How much does umbrella insurance typically cost?",
      "a": "Roughly $150–$400 per year for the first $1 million of coverage, with each additional million usually cheaper, often $75–$150 more, since it's a fairly rare and standardized risk for insurers to price. It's consistently one of the cheapest layers of protection per dollar of coverage available."
    },
    {
      "q": "Does umbrella insurance cover intentional acts or business liability?",
      "a": "No. Standard personal umbrella policies exclude intentional harm, business or professional liability (you need separate professional liability or business umbrella coverage for that), and contractual liability. It's designed for personal liability exposure — auto accidents, dog bites, slip-and-falls, and similar claims."
