How Much Car Insurance Do I Actually Need? A Guide

Most drivers need more car insurance than their state requires. The average collision claim costs $7,191 [1], yet many states set property damage minimums at just $10,000 to $25,000. That gap between what the law asks for and what an accident actually costs is where drivers get into financial trouble.

Here's the short answer: carry at least 100/300/100 liability limits, add collision and comprehensive if your car is worth more than 10 times the annual premium for those coverages, and always carry uninsured motorist coverage. This guide walks through the math behind each recommendation so you can decide what's right for your situation.

What Does Your State Actually Require?

Every state except New Hampshire requires drivers to carry auto insurance, typically with minimum liability limits like 25/50/25 [2]. But "required" and "enough" are two very different things.

Most states set minimums in a format like 25/50/25, which means $25,000 per person for bodily injury, $50,000 per accident for bodily injury, and $25,000 for property damage. Some states have recently raised their minimums because the old limits were so outdated. California jumped from 15/30/5 to 30/60/15 in 2025, and North Carolina moved to 50/100/50 in mid-2025 [2].

You can check your state's exact requirements on our state requirements page. But keep in mind that meeting the minimum just keeps you legal. It doesn't keep you financially protected.

The national average for minimum coverage is about $866 per year ($72 per month), and full coverage averages $1,803 per year ($150 per month), based on NAIC data analyzed by QuoteFii [1][3][4]. The difference matters, and the next section explains why.

Why State Minimums Usually Aren't Enough

The average collision claim costs $7,191 [1], yet many states cap property damage liability at just $10,000 to $25,000. State minimums were designed to get drivers on the road with some coverage, not to fully protect you in a serious accident.

The average incurred loss per collision claim was $7,191 in 2022, according to the NAIC [1]. That's just property damage. Medical costs are far higher. The average hospital stay after a car accident exceeds $60,000 [5]. If you cause a multi-car accident with injuries, total damages can easily reach $150,000 or more.

Say you carry a 25/50/25 policy (the minimum in many states) and you cause a three-car pileup. The medical bills for two injured passengers total $120,000, and vehicle damage comes to $40,000. Your policy covers $50,000 in bodily injury and $25,000 in property damage. You're personally on the hook for the remaining $85,000. That could mean wage garnishment, a lien on your home, or drained savings.

This is not a rare scenario. Roughly 15.4% of drivers on the road carry no insurance at all [6]. If one of them hits you, your own uninsured motorist coverage is the only thing standing between you and out-of-pocket costs.

How Much Liability Coverage Do You Need?

Liability insurance is coverage that pays for the other driver's injuries and property damage when you are at fault. Most drivers should carry at least 100/300/100 liability limits, which costs roughly $15 to $25 more per month than state minimums [7]. It's the foundation of your policy, and it's where most drivers are underinsured.

The recommended baseline for most drivers is 100/300/100:

• $100,000 bodily injury per person
• $300,000 bodily injury per accident
• $100,000 property damage

This level costs roughly $15 to $25 more per month than state minimums [7], and it covers the vast majority of accident scenarios. For context, that extra cost is a fraction of the national average of $150/month for full coverage.

Match Liability to Your Assets

Your liability limits should at least match what you could lose in a lawsuit. Here's a simple framework:

Your Net Worth	Recommended Liability	Additional Protection
Under $50,000	50/100/50 (minimum viable)	Consider UM/UIM
$50,000 to $500,000	100/300/100	Add UM/UIM
Over $500,000	250/500/250	Add $1M umbrella policy

Umbrella policies typically cost $150 to $400 per year for $1 million in additional liability coverage [8].

If you own a home, have retirement savings, or earn a steady income, you have assets worth protecting. A judgment from a serious accident can reach into all of those. The cost difference between 25/50/25 and 100/300/100 is usually small compared to what you'd lose without it.

Do You Need Collision and Comprehensive?

Collision covers damage to your own car in an accident. Comprehensive covers theft, weather damage, animal strikes, and vandalism. Neither is legally required, but your lender will require both if you're financing or leasing.

The 10% Rule

A practical test from experienced drivers: if your annual collision and comprehensive premium exceeds 10% of your car's current value, those coverages may not be worth the cost.

Say you own a 12-year-old sedan worth $4,000. You're paying $600 per year for collision coverage with a $500 deductible. If the car is totaled, you'd receive $3,500 after the deductible. At $600 per year, you'd need to total the car within six years just to break even. In that case, dropping collision and banking the savings makes financial sense.

On the other hand, if you drive a car worth $25,000 and your collision premium is $800 per year (3.2% of the car's value), keeping the coverage protects you from a significant loss. Learn more about choosing the right deductible to find the right balance.

When to Keep Full Coverage

You should carry collision and comprehensive when:

• You're financing or leasing (your lender requires it)
• Your car is worth more than $10,000
• You couldn't afford to replace the car out of pocket
• You park in areas with high theft or weather risk

You can likely drop them when:

• You own the car outright and it's worth under $5,000
• Your emergency fund could cover a replacement
• The annual premium exceeds 10% of the car's value

Don't Skip Uninsured Motorist Coverage

About one in seven drivers (15.4%) on the road has no insurance [6]. In some states like Mississippi, that number reaches 28.2% [6]. If an uninsured driver hits you, your own uninsured/underinsured motorist (UM/UIM) coverage pays your medical bills and repairs.

UM/UIM coverage is required in some states but optional in others. Even where it's optional, it's one of the most cost-effective coverages you can add. It typically costs $20 to $50 per year [9] and protects you from a risk that's completely outside your control.

Carry UM/UIM limits that match your liability limits. If you have 100/300/100 liability, get 100/300 for UM/UIM.

Paid-off car, worth $15K+	100/300/100	Yes (10% rule passes)	Match liability	Consider higher deductible
Paid-off car, worth under $5K	100/300/100	Likely drop	Match liability	Bank the savings
High net worth ($500K+)	250/500/250	Based on car value	Match liability	$1M+ umbrella policy
Young driver, tight budget	50/100/50 minimum	If financing, required	At least state minimum	Compare quotes to find savings

Coverage recommendations are general guidelines. Your state requirements, lender terms, and personal risk tolerance may differ.

How to Avoid Overpaying for the Right Coverage

Two drivers with identical 100/300/100 policies can pay very different rates depending on their carrier, discounts, and how recently they compared quotes. Carrying the right amount of coverage does not mean you should overpay for it.

The median driver who compares and switches saves $461 per year [10]. Here's how to get the right coverage at the right price:

1. Compare quotes from at least three carriers. Rates vary significantly between companies for the same coverage [9]. Use a comparison tool to see multiple options at once.
2. Raise your deductible if you have savings. Moving from a $500 to a $1,000 deductible typically saves 8 to 10% on collision and comprehensive [11]. More on the deductible tradeoff here.
3. Ask about discounts you might be missing. Bundling, safe driver, low mileage, and automatic payment discounts can stack up. See our full list of discounts you might be missing.
4. Re-shop every 6 to 12 months. Your rates change as your profile changes, and so do carrier pricing models. What was competitive last year may not be today.
5. Don't cut coverage to save money. Dropping liability limits from 100/300/100 to 25/50/25 might save $15 to $25 per month. But one serious accident could cost you everything you've saved and more.

Frequently Asked Questions

Is minimum coverage ever enough?

Minimum coverage keeps you legal, but it rarely provides adequate financial protection. With the average collision claim at $7,191 [1] and medical costs far exceeding that, minimums leave you exposed to lawsuits and out-of-pocket costs in any serious accident.

What does "full coverage" actually mean?

"Full coverage" isn't an official insurance term. Most people use it to mean liability plus collision plus comprehensive. It does not mean you're covered for everything. You may still need to add UM/UIM, gap insurance, or rental car coverage separately. See our coverage types guide for a complete breakdown.

How much does 100/300/100 cost compared to state minimums?

Upgrading from minimum liability to 100/300/100 typically adds $15 to $25 per month [7]. On a national average basis, minimum coverage runs about $72 per month and full coverage about $150 per month [1][4], though the liability upgrade itself is a smaller portion of that difference.

Should I get an umbrella policy?

If your net worth exceeds $500,000, an umbrella policy is strongly recommended. It adds $1 million or more in liability protection and typically costs $150 to $400 per year [8]. Even for drivers with moderate assets ($100K to $500K), an umbrella can be worthwhile given the low cost.

When should I drop collision coverage?

Consider dropping collision when your car's value minus the deductible is less than 10 times your annual collision premium. For example, if your car is worth $4,000 and your deductible is $500, you'd receive $3,500 in a total loss. If collision costs you $600 per year, you'd need nearly six years of claim-free driving just to break even.

The Bottom Line

The right amount of car insurance protects your finances without draining your budget. For most drivers, that means 100/300/100 liability, collision and comprehensive based on your car's value, and UM/UIM coverage that matches your liability limits. These levels cover the vast majority of real-world accident scenarios and cost surprisingly little more than bare minimums.

If you're unsure whether your current coverage is enough, or if you're paying too much for what you have, comparing quotes is the fastest way to find out. The median savings for drivers who compare and switch is $461 per year [10].
