How much car insurance do I need?

Figuring out how much car insurance you need can feel weirdly complicated. For many drivers, a good starting point is liability limits of 100/300/50, plus collision and comprehensive coverage if your car is expensive to replace (auto loan lenders also typically require this coverage for financed vehicles). But the “right” amount of coverage really depends on a myriad of factors.

Here’s how to figure out how much car insurance coverage you actually need (and where you might be able to save money without leaving yourself underinsured).

Minimum vs. recommended car insurance coverage

State minimum car insurance is the least amount of coverage you’re legally required to carry. Recommended coverage is what many insurance professionals suggest to better protect you financially if you cause a serious accident or your car is badly damaged.

These two things can be very different. For instance, your state minimum liability limits might only cover $25,000 worth of property damage. That might sound like a lot until you, for example, total someone’s newer SUV or cause a multi-car accident.

Here’s a simple breakdown of how minimum vs. recommended coverage usually compares:

How much liability insurance do you need?

For many drivers, liability coverage of 100/300/50 is considered a strong starting point. Here’s what these three numbers (which is how auto liability insurance is often represented) actually mean:

• $100,000 bodily injury liability per person: Covers injuries to one person in an accident you cause.
• $300,000 bodily injury liability per accident: Covers total injuries across everyone involved in the accident.
• $50,000 property damage liability: Covers damage you cause to someone else’s car or property.

If you caused an accident that injured multiple people and damaged another vehicle, your liability coverage would help pay up to these limits.

Many experts recommend carrying more than your state minimums, however, especially if you:

• Own a home
• Have savings or investments
• Have a higher income
• Simply want stronger financial protection

And for even more liability protection (like $300,000 to $1 million or more), you could need an umbrella insurance policy. Umbrella coverage adds an extra layer of liability protection on top of your auto and homeowners insurance limits.

Do you need full coverage insurance?

Full coverage insurance usually refers to having liability, collision, and comprehensive coverage together. In other words, it helps protect both other people and your own car.

Having full coverage often makes sense if:

• Your car is newer or still worth a decent amount.
• You have a loan or lease (lenders usually require it).
• You couldn’t easily afford to replace your car after a major accident.
• You live somewhere with higher risks for theft, hail, flooding, vandalism, or other non-crash damage.

On the other hand, you might decide full coverage isn’t worth it if:

• Your car is older and has low market value.
• The annual premium is getting close to what the car is worth.
• You could comfortably replace your vehicle yourself if it were totaled.

How much collision and comprehensive coverage do you need?

Unlike liability insurance, collision and comprehensive coverage aren’t usually applied in coverage amounts like 100/300/50. Instead, the payout is generally based on your car’s actual cash value (ACV) at the time of the claim.

So if your car is totaled, your insurer typically pays what the car was worth right before the accident or loss, minus your deductible (unless you have a special add-on like new car replacement coverage, which will pay to replace your vehicle with the same or a newer model).

That means the bigger decision usually isn’t how much collision or comprehensive coverage you need but whether carrying the coverage is worth the premium in the first place.

Here are some general rules of thumb that could help you decide:

• Collision coverage makes more sense for newer cars or vehicles that would be expensive to repair or replace after an accident.
• Comprehensive coverage can be valuable no matter what, especially if you live somewhere with risks like hail, flooding, theft, falling trees, or deer collisions.

How to choose the right deductible amount

Your car insurance deductible is the amount you agree to pay first before your insurance covers the rest (up to your policy limits). Common deductible amounts are $250; $500; $1,000; and even $2,000.

The higher deductible amount you choose, the lower your monthly premium will be. For example:

• Choosing a $1,000 deductible will usually make your monthly insurance bill cheaper.
• Choosing a $250 deductible means you’ll likely pay more each month, but less if you file a claim.

Realistically, the best deductible is usually the amount you could realistically afford to pay tomorrow if something happened to your car. This is the part that drivers sometimes overlook. Saving $20 per month sounds great until you, for example, suddenly need to come up with $1,000 after an accident. The goal is finding the balance between:

• A monthly premium you can comfortably afford
• An out-of-pocket cost you could realistically handle in an emergency

How your financial situation affects how much insurance you need

Figuring out how much car insurance you need requires you to consider your entire financial situation — not just your car. If you cause a serious accident and your insurance limits aren’t high enough, you could potentially be responsible for the remaining costs yourself. But if you have higher liability limits, they can help to protect your finances, including assets like savings, investments, or a home.

On the flip side, someone driving an older, paid-off car with very little savings might make different coverage decisions simply because the math doesn’t look the same.

Some factors that can affect how much coverage makes sense for you include:

• Your income and savings
• Whether you own a home or other assets
• How expensive your car would be to replace
• Whether you have a loan or lease
• Your risk tolerance and emergency savings

How to decide how much car insurance you need

There’s no single “perfect” amount of car insurance for everyone. However, here’s a quick way to think through different situations:

How much car insurance costs at different coverage levels

Car insurance rates vary based on your age, location, driving record, credit, and vehicle. But here’s a general idea of how different coverage levels compare:

• State minimum coverage: As of March 2026, the national average is $1,573 per year, according to Experian data.
• Higher liability limits (like 100/300/50): The national average is $1,822 per year for 100/300 coverage, according to the latest Policygenius data.
• Full coverage insurance: As of March 2026, $2,930 per year is the national average, according to Experian data.

Is minimum coverage enough for car insurance?

For some drivers, minimum coverage might technically be enough to meet legal requirements. But legally enough and financially enough are two very different things.

The biggest issue with minimum coverage is that the limits are often pretty low. For example, if your policy only includes $25,000 in property damage liability and you total a newer vehicle worth $45,000, your insurance might only pay up to that limit. The same idea applies to medical bills and lawsuits after a serious accident.

This doesn’t mean that everyone needs the highest coverage limits possible. But many drivers choose higher liability limits because the added protection can be worth the relatively modest increase in monthly cost.

How to lower your car insurance cost without sacrificing coverage

If car insurance feels expensive right now, there are ways to lower your premium without dropping to bare-minimum coverage. Here are several strategies that could help you save on car insurance:

• Compare quotes from multiple auto insurance companies. Rates can vary wildly between insurers for the exact same coverage. Shopping around is one of the easiest ways to potentially save money and get the car insurance you need at a fair price.
• Raise your deductible carefully. Choosing a higher deductible can lower your monthly premium. But make sure you do this only if it’s an amount you could realistically afford after an accident.
• Ask about discounts. Many insurers offer auto insurance discounts for bundling policies, low mileage, safe driving, being a student, paying in full, and more. Call and ask what’s available to you — you might be surprised.
• Keep your driving record clean. Tickets and accidents can raise rates for three or more years, depending on your state. Avoiding violations can make a big, long-term difference — keep up with safe driving habits and avoid any lapses in auto insurance coverage.
• Reevaluate coverage for older vehicles. If your car isn’t worth much anymore, it could make sense to drop collision coverage at some point (but still consider keeping higher liability limits if you have sizable assets).
