Trying to figure out how much car insurance you actually need? Most states require minimum coverage for auto insurance, but your insurance company usually advises full coverage.

Can you have too much car insurance? While it’s certainly true you can run — sometimes literally — into serious financial trouble with too little insurance coverage, your wallet would also argue that there’s such a thing as too much car insurance.

Ideally, the answer to "how much car insurance do I need" strikes a balance between affordability and covering all the costs associated with an auto accident, including medical bills, property damage, and car repairs.

How much car insurance is required in your state?

Looking at minimum requirements for basic car insurance in your state is a good place to start when you’re building an auto insurance policy. Most states require proof of car insurance coverage, specifically liability insurance, once you hit any public road.

Minimum liability insurance requirements vary from state to state, but the most common usually looks like this:

• $25,000 bodily injury per person

• $50,000 bodily injury per car accident

• $25,000 property damage per car accident

Some states also require uninsured motorist coverage, personal injury protection, or medical payments coverage.

Which states don't require car insurance?

There are two states where car insurance isn’t a requirement for all drivers. In New Hampshire, you still have to prove you have financial resources to cover an at-fault accident, and the state does require drivers with certain convictions like DUI or reckless driving to carry car insurance.

In Virginia, you can waive car insurance requirements by paying a $500 uninsured motorist fee.

How much liability coverage do I need?

You might be wondering if the state’s minimum requirements for liability car insurance are enough to protect you in the event of an at-fault accident. And the answer actually depends on your net worth.

Your net worth is a fairly simple calculation of the value of your assets (home, cars) plus any savings or investments you have minus your debts. Both your bodily injury liability coverage and your property damage liability limits should exceed your net worth. If they don’t, you’ll want to increase them to bridge the gap.

What would your financial responsibility look like if you didn’t increase your liability limits? Let’s say you’re at fault in a car accident where multiple people are injured and their medical expenses top $100,000. If you only have minimum bodily injury insurance coverage, the insurance company would cover medical bills up to $50,000, and you’d be personally responsible for the remaining $50,000.

5 types of recommended car insurance coverage

While additional insurance is not required, a majority of motorists carry extra coverage for a reason. Car accidents can be incredibly costly and a little insurance goes a long way toward deferring unexpected accident costs like lost wages or a rental car.

Here are the main types of auto insurance coverage you should consider and when it might make sense to pay a little more for protection on and off the road.

1. Collision coverage

Best for leased, financed, and new cars

Collision insurance covers damage to your car in the case of a motor vehicle accident. Collision coverage costs are affordable, so you should add it to your policy if you can’t afford the costs of repairing or replacing your vehicle.

2. Comprehensive coverage

Best for leased, financed, and new cars

Comprehensive insurance covers damage to your vehicle from weather, theft, vandalism, fire, and even animal strikes. Glass coverage is usually included in comprehensive and collision coverage. Comprehensive coverage is best for more expensive vehicles that you can’t afford to repair or replace out-of-pocket.

3. Personal injury protection (PIP)

Best for no-fault states

Personal injury protection is required in some states as part of no-fault accident insurance. PIP coverage pays for medical expenses not covered by health insurance, childcare, lost wages, funeral expenses, and rehabilitation from injuries incurred in a car accident regardless of fault.

4. Medical payments (MedPay) coverage

Best for those without health insurance

Medpay is an optional coverage available in some states that pays for medical bills. It can be a good idea even if you have good health insurance but are worried about being able to pay your out-of-pocket medical expenses or meeting your deductible after a car accident.

5. Uninsured/underinsured motorist coverage

Best for everyone

Some states require drivers to protect themselves from damages and injuries caused by a hit-and-run from uninsured or underinsured motorists. According to the Insurance Research Council, one in eight drivers is uninsured or underinsured. In some states like Mississippi, the percentage can climb to nearly 30% of motorists on the road driving without insurance.

Uninsured motorist insurance, or UIM, protects you, your passengers, and your vehicle if you are the victim in an accident caused by a driver without car insurance.

5 kinds of additional coverage

Here are five other less common types of car insurance coverage available from auto insurance companies that you may want to consider.

1. Gap insurance

If you bought a new (or new to you car) or if you’re leasing a car, you may need or be required by your lender to get gap coverage. This type of insurance protects you (or the leasing company) in the event your vehicle is a total loss and the actual cash value the insurance pays doesn’t meet your car loan obligations.

2. Rental reimbursement

Rental reimbursement coverage is a type of insurance that will pay the costs of a rental car if your vehicle is damaged in a covered claim. It’s relatively inexpensive and can cover other costs besides a rental car, including rideshare services or public transportation costs.

3. Roadside assistance

Getting roadside assistance coverage as part of your insurance premium can pay off for drivers who own an older car, have long commutes, or just don’t want the hassle of emergency roadside repairs or the agonizing wait for a jump start.

4. Classic car insurance

Classic car insurance policies recognize the intangibles that make older or collector vehicles valuable — typically far more valuable than the day they rolled off the showroom floor. For the insurance to remain affordable, however, classic car insurance provides less coverage than standard auto insurance. For example, it won’t cover the car if it’s used for regular transportation or is not securely stored.

5. Rideshare insurance

Personal car insurance doesn’t usually cover driving for business use, which is where rideshare insurance comes in, helping close coverage gaps when you drive for a rideshare company in your spare time.

This type of insurance is typically sold as an add-on to your personal car insurance policy, meaning you don’t need a separate rideshare insurance policy.

What coverage limits should I have on my car insurance policy?

Determining your coverage limits really boils down to your net worth and how comfortable you are with paying out-of-pocket expenses in the event of an accident. However, here are some commonly recommended coverage limits to consult when you’re buying car insurance.

The cost of having these coverage limits will vary depending on several factors, including your driving history, vehicle, and deductible. And keep in mind that some of these types of insurance aren’t available everywhere and have maximum and minimum coverage limits mandated by each state.

5 steps to determining how much car insurance you need

Before buying car insurance, it pays to do your research. Here’s a step-by-step guide to what you’ll need to know before gathering car insurance quotes.

1. Know your net worth

Because you’ll need liability coverage limits that protect your assets, you should have at least a ballpark estimate of your net worth before you talk to an insurance agent.

2. Know your state minimum requirements

Don’t get ambushed by surprise state requirements. Research whether you live in an at-fault or no-fault state and what the minimum requirements are for liability and uninsured motorist coverage. For instance, New York, Oregon, and Florida are all no-fault states while Alaska and Maine are at-fault states.

3. Determine your financial risk

Part of determining how much car insurance you need is how comfortable you are with the risk of significant out-of-pocket expenses. For instance, Progressive indicates a basic auto insurance policy starts at $81 per month, but you may be willing to pay an extra $25-$50 more per month to get better coverage or a lower deductible.

4. Try an insurance coverage calculator

Quite a few insurance companies offer coverage calculators so you can determine the amount of car insurance you need and your car insurance rates depending on your state of residence, the vehicles you own, your driving record and how much your home costs.

5. Get at least three car insurance quotes

The Insurance Information Institute recommends putting yourself in the driver’s seat by getting at least three different auto insurance quotes to better understand your coverage options and car insurance costs. You can shop online using a comparison tool.
