Umbrella Insurance Calculator
Coverage amount based on net worth and risk profile.
Recommended umbrella coverage
$1,000,000
Umbrella sits on top of auto + home liability. Cheap insurance — typically $200-$400/yr per $1M of coverage.
Umbrella insurance is the coverage that sits on top of your auto and home liability and kicks in when a lawsuit exceeds those limits. It’s cheap relative to what it protects — often a few hundred dollars a year for $1M+ — but only if you buy the right amount.
This calculator sizes umbrella coverage to what you actually need to protect: your net worth plus future income that a judgment could come after.
How this calculator works
A common guideline is to carry umbrella coverage at least equal to your net worth, since that’s what a large judgment can reach. The calculator totals your assets (home equity, savings, investments) and adds a buffer for future income, then subtracts the liability limits you already carry on auto and home — the gap is the umbrella amount to consider.
Assumptions and data behind the estimate
Recommended coverage follows the common guideline of carrying umbrella limits at least equal to your net worth — the amount a large judgment can reach — plus a buffer for future income, minus the liability limits already on your auto and home policies. It is a planning guideline, not underwriting; insurers require minimum underlying limits (often $250k/$500k auto) and price on your specific exposures.
What affects the number
- Net worth — home equity, savings, and investments a judgment could target
- Future income exposure (wages can be garnished to satisfy a judgment)
- Existing auto and home liability limits (umbrella sits above these)
- Risk profile — a pool, teen drivers, a dog, rental property, or a public profile raise exposure
- Umbrella policies usually require minimum underlying limits (e.g., $250k/$500k auto)
Frequently asked questions
How much umbrella insurance do I need?
A good rule is to carry at least as much umbrella coverage as your net worth, since that’s what’s exposed in a large lawsuit. Many advisors add a buffer for future income. The calculator gives you a number based on your assets and existing limits.
Is umbrella insurance worth it?
For most people with meaningful assets or higher-risk exposures (teen drivers, a pool, rental property), yes — $1M of coverage often costs only $150–$300/year, far less than a single serious judgment.
What does umbrella insurance cover?
It extends your liability coverage above auto and home limits for things like serious at-fault accidents, injuries on your property, and certain personal-injury claims (libel, slander). It doesn’t cover your own property or business liability.
