Uninsured Motorist Coverage Need Calculator

Calculate how much uninsured motorist coverage you need based on medical costs, lost wages, and the rate of uninsured drivers in your state.

About the Uninsured Motorist Coverage Need Calculator

About 1 in 8 drivers on the road has no auto insurance. If an uninsured driver hits you, your only financial protection is your own uninsured motorist (UM) coverage. Without it, you'd be responsible for your own medical bills, lost wages, and vehicle repairs — even though the accident wasn't your fault.

This calculator estimates the uninsured motorist coverage you need based on potential medical expenses, lost income, and the percentage of uninsured drivers in your area. It helps you determine appropriate UM bodily injury and property damage limits.

Why Use This Uninsured Motorist Coverage Need Calculator?

Getting hit by an uninsured driver can be financially devastating. Average emergency room visits cost $2,000-$3,000, and serious injuries can run into six figures. UM coverage is your safety net, often costing only $20-$50 extra per year. This calculator shows the potential gap so you can make an informed coverage decision.

How to Use This Calculator

  1. Enter estimated medical costs if you were seriously injured in an accident.
  2. Enter your monthly income to calculate potential lost wages.
  3. Enter the estimated months of recovery time.
  4. Enter the percentage of uninsured drivers in your state.
  5. Review the recommended UM coverage limits.

Formula

Potential Medical Costs = Estimated Medical Expenses Lost Wages = Monthly Income × Recovery Months Total Exposure = Medical Costs + Lost Wages + Pain & Suffering (estimated at 1.5× medical) Recommended UM Coverage = Total Exposure rounded to nearest standard limit Risk Factor = Uninsured Driver Rate / 100

Example Calculation

Result: $250,000 UM coverage recommended

With potential $50,000 medical costs, $15,000 lost wages (3 months at $5,000/mo), and $75,000 estimated pain & suffering (1.5× medical), total exposure is $140,000. With 13% of drivers uninsured, the recommended UM coverage is $250,000 per person to provide adequate protection.

Tips & Best Practices

The Hidden Risk on Every Road

One in eight drivers has no insurance. In some states, it's one in four. When an uninsured driver causes an accident, victims face medical bills, lost wages, and vehicle damage with no one to pay. Suing an uninsured driver rarely produces results since they typically lack assets.

Why UM Coverage Is a Bargain

UM coverage typically costs $20-$50 per year for $100,000/$300,000 limits. That's equivalent to a few coffees per month for protection against potentially devastating financial losses. It's one of the best values in auto insurance.

Stacking UM Coverage

Some states allow "stacking" — multiplying your UM limits by the number of vehicles on your policy. If you have $100,000 UM coverage and two cars, stacking gives you $200,000 in protection. Ask your agent about stacking availability in your state.

Frequently Asked Questions

What is uninsured motorist coverage?

Uninsured motorist (UM) coverage pays for your injuries and damages when you're hit by a driver who has no insurance. It acts as a substitute for the at-fault driver's nonexistent liability policy, covering your medical bills, lost wages, and pain and suffering.

How many drivers are uninsured?

Nationally, about 12.6% of drivers are uninsured. However, rates vary dramatically by state — from under 5% in Maine and Massachusetts to nearly 30% in Mississippi. Urban areas tend to have higher uninsured rates.

Is uninsured motorist coverage required?

It depends on your state. About 20 states require UM coverage, while others make it optional. Even where it's optional, most insurance experts strongly recommend it given the high rate of uninsured drivers.

Does UM coverage apply to hit-and-run accidents?

Yes, in most states. If a hit-and-run driver injures you and can't be identified, your UM coverage typically applies. Some states require physical contact between vehicles; others cover all hit-and-run scenarios.

What's the difference between UM and UIM coverage?

UM (uninsured motorist) covers you when the at-fault driver has NO insurance. UIM (underinsured motorist) covers you when the at-fault driver has insurance but not enough to cover your damages. They're often sold together.

Does UM coverage raise my premium if I use it?

Generally no. Since UM claims involve accidents that aren't your fault, most states prohibit insurers from surcharging your premium after a UM claim. However, practices vary by state and insurer.
