How much car insurance do I need? (2026 coverage guide)
The honest coverage guide. State minimums protect almost no one with assets. The right baseline is 100/300/100 plus uninsured motorist — usually $5–$25/month more.
Most drivers carry too little car insurance — usually because they bought at state minimums and never re-evaluated. A single at-fault accident with injured parties can produce $250K+ in medical bills. State minimums of 25/50/25 expose you personally for everything above $25K per injured person.
The cost difference between dangerously low and adequately protected is usually $5–$25 a month — the best dollar-for-dollar protection in personal finance.
How car insurance coverages are written
A liability policy is typically written as three numbers, in thousands of dollars: 100/300/100.
- First number ($100K): Bodily injury liability per person.
- Second number ($300K): Bodily injury liability per accident (total across all injured parties).
- Third number ($100K): Property damage liability per accident.
State minimums in most states are 25/50/25 — and that's nowhere near enough. Mid-back surgery alone often runs $80K+. A single passenger with a broken leg can exceed $25K. State minimums work for the no-asset, no-income, easy-to- judgment-proof driver — which probably isn't you.
The recommended baselines
| Profile | Liability | UM/UIM | Umbrella |
|---|---|---|---|
| Renter, <$50K assets | 100/300/100 | 100/300 | — |
| Homeowner, $100K–$250K net worth | 100/300/100 | 100/300 | Optional |
| $250K–$1M net worth | 250/500/250 | 250/500 | $1M |
| $1M+ net worth | 250/500/250 or higher | 250/500+ | $2M+ |
| Teen driver in household | Bump up one tier | Same | Strongly recommended |
Rule of thumb: liability limits should be at least equal to your net worth. Below that and a serious accident exposes your assets.
The other coverages you probably need
Uninsured/underinsured motorist (UM/UIM)
~1 in 8 U.S. drivers is uninsured (Insurance Research Council). When an uninsured driver hits you, your own UM coverage steps in to pay your medical bills and lost wages. UIM kicks in when the at-fault driver's limits are too low to cover your damages.
Match UM/UIM limits to your liability limits. Adding UM/UIM at 100/300 typically costs $5–$15/month. Outsized protection for the price.
Comprehensive and collision
- Collision — pays for damage to YOUR car in an accident regardless of fault.
- Comprehensive — pays for non-collision damage (theft, vandalism, weather, animal strike).
Keep both when your car's actual cash value is over $4,000–$5,000. Drop both when annual premium for comp + collision exceeds 10% of car ACV. Look up your car's ACV on Kelley Blue Book.
Personal Injury Protection (PIP) / MedPay
PIP pays your medical bills regardless of fault (required in no-fault states). MedPay is similar but optional. If your health insurance is good (low deductible, broad network), keep PIP/MedPay at the minimum. If your health insurance is thin or high-deductible, raise PIP/MedPay to $5K–$10K.
The umbrella policy — high leverage for high net worth
An umbrella policy adds $1M–$5M of extra liability coverage on top of your auto and homeowners policies. Typically $150–$400/year for $1M of coverage — by far the cheapest large-coverage insurance dollar available.
When you should have one:
- Net worth (home equity + retirement + savings + business equity) over $250K.
- You own a rental property.
- You have a teen driver in the household.
- You own a dog (especially a "high risk" breed per insurer lists).
- You're a public-facing professional (doctor, lawyer, real estate agent) with extra exposure.
- You have a pool, trampoline, or other "attractive nuisance."
Requirement: umbrella policies usually require you to first carry higher liability limits on auto (250/500/250) and home ($300K+) before they'll attach.
Coverages most people overpay on
- Rental car reimbursement — $1–$3/month for $30/day rental coverage. Skip if you have a credit card with rental coverage or if you could absorb the cost.
- Roadside assistance — $1–$3/month. AAA or your credit card may already cover it.
- New car replacement — only useful for cars under 2 years old. Drop when the car is older.
- OEM parts endorsement — useful for newer cars; small fee.
- Glass coverage — useful in some markets, optional in others.
How to actually size your coverage
- List your net worth — home equity + retirement + investments + savings + business interests minus debts.
- Set liability AT LEAST equal to net worth, rounded up to standard tiers (100/300/100, 250/500/250, etc.).
- Match UM/UIM to liability.
- Decide on comp/collision based on car ACV (drop if < $4K).
- Add umbrella if net worth $250K+ OR high-exposure profile.
- Audit annually — net worth grows, coverage should keep pace.

The bottom line
100/300/100 liability + matching UM/UIM is the right baseline for almost anyone with assets. Going from state minimums to that baseline typically costs $5–$25/month — the best protection-per-dollar in personal finance.
High net worth households should add 250/500/250 liability + a $1M+ umbrella policy. Low-value cars can drop comp/collision; everyone else should keep both.

Frequently asked questions
- Are state minimums enough?
- Almost never for any driver with assets to protect. State minimums are often 25/50/25 or lower — $25K bodily injury per person, $50K total per accident, $25K property damage. One serious accident with even moderate medical bills can blow through that, leaving you personally liable for the rest. The cost difference to move to 100/300/100 is usually $5–$25/month — cheap protection.
- What's the right liability coverage for most people?
- 100/300/100 as a baseline — $100K bodily injury per person, $300K per accident, $100K property damage. Goes up from there as your net worth or income grows. Anyone with $250K+ in assets should consider an umbrella policy on top.
- Should I have comprehensive and collision?
- Yes if your car is worth more than $4,000–$5,000 of actual cash value. No if it's older and the annual premium for comp + collision exceeds ~10% of the car's value. Liability stays mandatory either way.
- What's uninsured/underinsured motorist coverage?
- Protection when the at-fault driver has no insurance or insufficient limits. About 1 in 8 U.S. drivers is uninsured. UM/UIM covers your medical bills and lost wages when you can't recover from the at-fault party. Often cheap (~$5–$15/month) and worth taking at limits matching your liability.
- Do I need an umbrella policy?
- Yes if your net worth (home equity + retirement + savings + business interests) is $250K+ OR if you have public-facing exposure (rental property, teenage driver, dog owner, public profession). A $1M umbrella typically runs $150–$400/year — the cheapest large-coverage insurance dollar in personal finance.
- What's the cost of going from state minimum to 100/300/100?
- Typically $5–$25/month — small relative to the protection. The cost-to-coverage ratio is best at this step than at any other. Going from 100/300/100 up to 250/500/250 is also cheap (~$5–$15/month more) and worth it for higher-asset households.
