How Much Car Insurance Do You Actually Need?
It usually starts with a fender bender. A quick stop, a distracted second, and suddenly there’s damage, paperwork, and an uncomfortable question: is your insurance actually enough to cover this? For a lot of drivers, the honest answer only becomes clear after the accident already happened — which is exactly the wrong time to find out.
State minimum coverage will keep you legal. It won’t necessarily keep you financially protected. Here’s how to figure out the difference.
The short answer
Most insurance experts, including the Insurance Information Institute and Consumer Reports, recommend liability coverage of at least 100/300/100 — meaning $100,000 in bodily injury coverage per person, $300,000 per accident, and $100,000 in property damage coverage. That’s well above what most states legally require, and it exists for a simple reason: the gap between state minimums and real accident costs has gotten wide.
If you have significant assets to protect — savings, home equity, investments — experts generally recommend going higher, to 250/500/250.
Why state minimums usually aren’t enough
Every state except New Hampshire requires some form of liability insurance, but the minimums vary widely and haven’t kept pace with actual medical and repair costs. Some states still require as little as $25,000 in per-person bodily injury coverage. A single moderate hospital stay after a crash can exceed that limit on its own, leaving you personally responsible for whatever your policy doesn’t cover.
Several states raised their minimums in 2025 and 2026 — California increased its requirements for the first time since 1967 — but even the updated numbers in most states fall short of what a serious accident can actually cost.
How to figure out your number
Your right coverage level comes down to four questions:
1. What are your assets worth? Insurance is designed to protect what you have, not just what your state requires. If someone sues you after an at-fault accident, they can potentially go after your savings, home equity, and future wages if your liability coverage doesn’t cover the full claim. A rough guideline:
- Under $50,000 in assets: consider 50/100/50 if you can afford it
- $50,000–$500,000 in assets: 100/300/100 is the common recommendation
- Above that: consider 250/500/250, or add a separate umbrella policy
2. Is your car financed or leased? If so, your lender almost certainly requires full coverage — meaning liability plus collision and comprehensive — along with a set deductible, usually around $500. Check your loan or lease agreement for the exact requirement rather than assuming state minimums apply.
3. Could you afford to repair or replace your car out of pocket? If not, collision coverage (which pays for damage from an accident, regardless of fault) and comprehensive coverage (which covers theft, weather, vandalism, and animal damage) are worth carrying even if your lender doesn’t require them.
4. What are the uninsured driver rates where you live? Roughly one in three US drivers is uninsured or underinsured. Without uninsured/underinsured motorist coverage, your only recourse after being hit by one is a lawsuit — and if the other driver has no money, that lawsuit won’t get you much. Most experts recommend matching your UM/UIM limits to your liability limits, even in states where it isn’t required.
Liability vs. full coverage: what’s the actual difference?
Liability-only covers injuries and property damage you cause to others. It does not pay to repair or replace your own car.
Full coverage adds collision and comprehensive on top of liability, covering damage to your own vehicle regardless of the cause. It costs more — typically an extra $50 to $250 a month depending on your location, car, and driving record — but it’s the only option that protects your own vehicle.
A common rule of thumb: if your annual full-coverage premium equals 10% or more of your car’s current market value, or your car is more than 10 years old, it may make more financial sense to drop collision and comprehensive and self-insure that risk instead.
Other coverages worth knowing about
- Gap insurance — pays the difference between what you owe on a loan and what your car is actually worth if it’s totaled. Especially useful in the first two to three years of a loan, when new cars depreciate fastest. It’s usually cheaper through your insurer than through the dealership.
- Personal injury protection (PIP) — required in 12 states, this covers your own medical bills and lost wages after an accident regardless of fault.
- Umbrella insurance — if you have significant assets and want liability protection beyond what a standard auto policy allows, an umbrella policy adds coverage in increments, often starting at $1 million, layered on top of your existing auto and home policies.
Frequently asked questions
What does 100/300/100 car insurance mean? It means $100,000 in bodily injury liability coverage per person, $300,000 per accident total, and $100,000 in property damage liability coverage. It’s a commonly recommended coverage level that sits well above most state minimums.
Is full coverage car insurance worth it? It depends on your car’s value and your ability to cover repair or replacement costs out of pocket. Full coverage is generally worth it for financed or leased vehicles and newer cars, and less necessary for older cars worth only a few thousand dollars.
How much does full coverage car insurance cost compared to liability-only? Liability-only policies average roughly a third of the cost of full coverage, though exact numbers vary significantly by state, driving record, and vehicle.
Do I need uninsured motorist coverage if it’s not required in my state? Most experts recommend it regardless, since a significant share of drivers on the road are uninsured or underinsured, and without this coverage your only option after being hit by one is a lawsuit.
