How much car insurance do I need?
Choosing car insurance limits is more than meeting your state’s minimum. Use this guide to match coverage to your car, your loan or lease, your budget, and the risk you can afford—without over- or under-insuring.
Start with your state minimums (then check if they’re enough)
Every state sets required minimum limits for things like liability. The minimum is designed to meet legal requirements—not to protect you if you cause a serious crash.
In many situations, the cheapest policy that only meets minimums can leave you exposed. If you injure someone or damage property beyond your limits, you may have to pay the difference out of pocket.
Your goal is usually to choose limits high enough to cover the worst “reasonable” outcome for your situation—not just what’s required.
Liability coverage: protect your savings and future income
Liability coverage pays when you’re at fault and cause injuries or property damage to others. It’s commonly the most important part of deciding “how much” insurance you need.
A practical way to think about it: compare your liability limits to what you could reasonably lose in a claim or lawsuit. If you have savings, a home, investments, or strong future earnings, higher liability limits can be a safer choice.
If you’re a new driver, recently got your license, or are considered higher-risk in your state, you may want to be extra careful. Higher risk can mean a greater chance of claims, so “just minimums” can be riskier.
Collision and comprehensive: base it on the value of your car and your loan terms
Collision helps pay to repair or replace your car after a crash, even if it’s your fault. Comprehensive helps with non-crash events like theft, vandalism, hail, and many types of weather damage.
Whether you carry collision and comprehensive often depends on two things: (1) your car’s current value and (2) your loan or lease requirements. Many lenders require these coverages while you still owe money, and your policy may also require specific deductible amounts.
If you own an older car with low market value, some drivers drop collision and comprehensive. That can lower your premium, but it also means you’d pay for repairs or replacement if something happens. Consider what you could afford to pay immediately after a loss.
Uninsured/underinsured motorist: when other drivers don’t have enough
Even when you carry liability coverage, the other driver’s insurance may be too low—or they may be uninsured. Uninsured motorist (UM) and underinsured motorist (UIM) can help cover you and your passengers in those situations.
Some states require certain UM/UIM coverage. In others, it’s optional, but it can still be important. If you live in an area where crashes with uninsured or underinsured drivers are a known concern, this coverage can fill a real gap.
If you want a simple approach, many people consider matching UM/UIM liability limits to their liability coverage so the protection level is similar.
Medical payments and personal injury protection (PIP): plan for treatment costs
Medical payments coverage (MedPay) helps pay for certain medical bills after an accident, regardless of fault, up to the coverage limit. Personal Injury Protection (PIP) is required in some states and can work similarly, depending on local rules.
The right amount depends on what health insurance covers, whether you have medical coverage limits, and how you want expenses handled after a crash. If you don’t have strong health coverage or you want more predictable help with bills, higher limits for MedPay/PIP may be worth it.
Also think about time off work and follow-up care. Insurance can help, but not every policy covers every type of expense.
Deductibles and limits: the levers that usually change your price
Insurance has “limits” (the maximum it pays) and “deductibles” (what you pay first when you file a claim). Higher deductibles often lower premiums, but you must be able to pay that deductible when something happens.
If you choose a low deductible to reduce your out-of-pocket cost during a claim, you may pay more each month. If you choose a higher deductible, make sure it fits your savings plan.
When you review policy options, don’t just compare the monthly total. Look at the coverage types, the liability limits, UM/UIM limits, and how deductibles apply to collision and comprehensive.
How to compare coverage amounts and avoid common mistakes
When comparing policies, look at the actual coverages and limits—not only the premium. A plan that looks cheaper can be missing important protection (like UM/UIM or comprehensive/collision) or may have much lower liability limits.
Use how to read a car insurance policy to understand the difference between liability limits, deductibles, and optional coverages. Then use how to compare car insurance quotes to compare apples to apples.
Common mistakes to avoid:
- Choosing only state minimums when you can’t afford the gap
- Forgetting about loan/lease requirements for collision and comprehensive
- Picking deductibles you can’t realistically pay after a loss
- Skipping UM/UIM or underestimating how it helps when another driver has little coverage
- Relying on the cheapest number without checking coverage limits
Get help choosing limits that fit your situation
If you’re not sure which coverages and limits match your car, loan, and risk level, you can get guidance from a licensed insurance professional. CoverPair is a free matching service that helps you find and connect with a licensed insurance agent or broker in your state.
A good agent can explain what your state typically requires, what options mean in plain language, and which coverages are usually most important for your situation—without you needing to guess.
Before you share any details, remember: don’t provide sensitive numbers (like your Social Security number, driver’s license number, or policy numbers) on a matching form.
Quick checklist: decide “how much” car insurance you need
Use this checklist to guide your comparison when shopping for coverage.
- Liability: Choose limits that protect your assets and future income, not only the state minimum
- Collision/Comprehensive: Confirm any loan/lease requirements; decide based on car value and what you can afford to pay
- UM/UIM: Consider matching UM/UIM to your liability limits for similar protection
- MedPay/PIP: Pick limits based on your health coverage and your preference for predictable accident expense help
- Deductibles: Choose deductibles you can pay without stress if you file a claim
Pick liability limits that protect you beyond the state minimum, add collision/comprehensive based on your car value and loan rules, and compare deductibles and limits—not just monthly cost.
