About this calculator
Umbrella liability sits above your auto and homeowners limits and pays when a judgment exceeds them. The right amount is not a guess: creditors can reach your non-exempt assets and, in many states, garnish future wages, so the standard planning rule is to carry at least your net worth excluding protected assets, then add a slice of future earnings if you are early in a high-income career. This calculator totals your exposure — home equity, investments outside retirement accounts, business equity, and a discounted portion of future income — subtracts assets protected by your state's exemptions (retirement accounts are broadly protected under federal law, and homestead exemptions vary from nothing to unlimited), and rounds the result to the million-dollar increments umbrella policies are sold in. It also estimates annual cost, which is famously cheap: the first million typically runs $150-350 a year, with each additional million costing less than the one before, because the probability of piercing a higher layer falls steeply.

FAQ
Do I need an umbrella if I don't feel wealthy?
The trigger is exposure, not wealth. Teen drivers, a pool or trampoline, a dog, rental property, and volunteer board service all raise the chance of a claim above your auto or home limits, and future wages can be garnished in many states.
Are retirement accounts safe from judgments?
ERISA-qualified plans have strong federal protection and IRAs have substantial protection that varies by state. That is why they are excluded from the exposure figure here — but confirm your state's rules rather than assuming.
Why does the insurer require higher underlying limits?
The umbrella only attaches above a required underlying limit, commonly 250/500 or 500 combined single limit on auto. Carrying less can leave a gap you pay yourself, so raise the base policy first.
Does umbrella cover business liability?
Personal umbrella policies exclude business activities. A business needs commercial excess or umbrella coverage sitting above its own general liability and commercial auto policies.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
