How much car insurance do I need?

You need at least enough car insurance coverage to meet your state’s minimum requirements; the most common required limits are $25,000 per person and $50,000 for bodily injury and $25,000 per incident for property damage. However, some states have much lower requirements and some states have higher limits.

In addition, you may need uninsured/underinsured motorist coverage, personal injury protection, and medical payments in some states. And finally, if you have a loan or lease, you need comprehensive and collision.

How much car insurance coverage you need beyond the requirements depends largely on your level of risk, what you have to lose and how much you can afford to pay out-of-pocket. Below we’ll take a closer look at how much car insurance you need.

How much car insurance do you need?

How much auto insurance coverage you need depends on your vehicle, your financial status, your state, and what you want from coverage.

Liability insurance is the foundation of a car insurance policy, and it’s required by law in most states. Some states require additional coverage, including uninsured motorist insurance and personal injury protection.

If you have a loan or lease, you’re required to carry comprehensive and collision coverage; along with state requirements, that’s known as full coverage. Even if you own your car outright, you should carry full coverage if you can’t afford to repair or replace your car out-of-pocket.

There are a lot of coverage options you can add for more protection, and you can increase your coverage limits, too. To find out how much car insurance you need, it’s important to understand how each coverage works and think about your personal financial situation.

State minimum car insurance requirements

Each state defines the minimum amount of coverage you require just to be on the road legally. These coverages are a starting point but are rarely enough coverage to really protect you on the road. In addition, there are no state requirements that provide protection against damage to your car.

Types of car insurance coverage and how much you need

There are a lot of different types of car insurance coverage. Some are considered part of a basic policy, others part of a full coverage policy and yet others are add-on options you can pick and choose. To make sure you have enough coverage, it’s important to understand what those coverages are and how much you need.

Car insurance coverage that may be required

Let’s start by looking at the car insurance coverages that may be required either by law or by your lender if you financed your car.

Liability

One of the most important types is liability insurance, mandatory coverage in nearly every state. The two types of liability coverage included in auto insurance policies are:

• Bodily injury (BI). Pays for injuries you cause to others in an accident.
• Property damage (PD). Pays for damage to others’ property you cause in an accident.

Liability limits are written like this: 50/100/50. In this example, the coverage limits are $50,000 per person for bodily injury, $100,000 per incident for bodily injury, and $50,000 per incident for property damage. Many states’ minimum limits are much lower than this.

How much liability coverage you need depends on a lot of factors, but experts recommend at least 100/300/100 for most people.

Uninsured/underinsured motorist (UM/UIM)

Uninsured motorist coverage reimburses you when an uninsured motorist causes an accident or when you’re involved in a hit-and-run accident.

"This is usually an affordable coverage to add on and a great way to further protect yourself from others on the road," suggests Tiffany Lemke, senior manager of Customer Experience for Metromile.

Your limits should match your liability limits for this coverage.

Personal injury protection (PIP) and medical payments (MedPay)

Personal injury protection pays your medical bills and other related costs regardless of fault in an accident. It’s required in some states, but not offered in all.

"For those who live in a no-fault state, personal injury protection coverage extends to you and passengers in your vehicle. It covers you regardless of fault and is primary coverage -- meaning you must submit your medical bills to your car insurance provider first," says Damico. 

How much PIP coverage you need depends on state laws and also your health insurance. If you have good health insurance, you may be ok with a minimum amount of PIP.

Collision and comprehensive

Collision and comprehensive coverage both pay for damage to your car but from different sources.

Collision coverage pays for repairing or replacing your vehicle if you crash into another vehicle or object or in a single-car accident. 

Comprehensive insurance, also optional, "provides coverage against theft and damage caused by an incident other than a collision, such as theft, vandalism, fire, flood, hail, falling rocks or trees, and other non-collision hazards," says Mark Friedlander, director of corporate communications for the Insurance Information Institute.

You don’t have to choose the amount of coverage since it’s based on the value of your car, but you will choose the deductible. A higher deductible means lower rates, but you need to be sure you can pay it, so choose wisely. This coverage is required if you have a loan or lease.

Car insurance coverage that’s always optional

There are other types of auto insurance coverage that aren’t mandatory but are often recommended. Consider your personal needs when adding options; many are low-cost and provide extra peace of mind.

Roadside assistance

Roadside assistance provides towing or help on the side of the road if something goes wrong, like a flat tire or dead battery. You can add roadside emergency assistance for a small amount, usually only a few dollars a month. It’s generally more affordable than a motor club membership.

Rental reimbursement

Rental reimbursement covers the cost of a rental vehicle while your car is being repaired, as long as it’s for a covered claim.

Gap insurance

"Gap insurance covers the difference between a car's actual cash value when it is stolen or wrecked and the amount the consumer owes the leasing or finance company," says Friedlander.

If you finance or lease your vehicle, you may be required to purchase gap insurance. If the debt you owe on a lease or loan is more than your vehicle is worth, getting gap insurance is a smart choice.

Accident forgiveness

Many carriers offer accident forgiveness coverage, which may prevent your auto premium from going up as a result of being involved in an at-fault accident (usually your first accident).

Full glass replacement

Although comprehensive insurance covers glass, you might be able to add full glass replacement coverage, which pays to repair or replace auto glass with no deductible.

How much car insurance do experts recommend?

While no one wants to overpay for coverage they don’t really need, it’s rare that extra car insurance is a bad investment, especially when it comes to liability insurance. In a serious accident, state minimum liability limits will be met and exceeded very quickly. Even a moderate accident can leave you with bills.

Some states have property damage limits as low as $5,000-$10,000. That’s not nearly enough when you consider the average cost of a new car is over $40,000 according to Kelley Blue Book. If you’re responsible for totaling a new car, you could be in real trouble with state minimum coverage.

When it comes to optional coverage, it’s best to weigh your financial resources. As a general rule, if you can’t afford the potential out-of-pocket cost without insurance, you should buy the coverage.

Average cost of car insurance by state and coverage level

Part of deciding how much car insurance you need is knowing how much it will cost. State minimum coverage is always the cheapest option, but shopping around can help you get better coverage at an affordable price.

For comparison, here are the average car insurance costs by state for both full coverage at 100/300/100 with $500 deductibles and state minimum liability coverage.
