National Average Car Insurance Cost
2026 estimates from NAIC data, CPI-adjusted to current dollars
The average cost of car insurance in the US is $150 per month ($1,803 per year) for full coverage in 2026, based on NAIC data adjusted for inflation using the BLS Consumer Price Index. Minimum coverage (liability only) averages $72 per month ($866 per year). The gap between full and minimum coverage is $78 per month ($937 per year). See our methodology.
How is this calculated?
Our full coverage national average uses the NAIC combined average premium ($1,438 in 2023), which reflects what drivers actually paid. We adjust this figure to current dollars using the BLS Consumer Price Index for motor vehicle insurance. Other sites may report higher averages because they use rate quotes (what insurers offer) rather than actual premiums paid. See our full methodology.
| Coverage Type | Monthly Average | Annual Average |
|---|---|---|
| Minimum (Liability Only) | $72 | $866 |
| Full Coverage | $150 | $1,803 |

What Full Coverage Includes
Full coverage is not a single policy. It is a bundle of three separate coverages: liability (required by nearly every state), collision (pays to repair your car after an accident regardless of fault), and comprehensive (covers non-collision damage like theft, hail, flooding, and animal strikes). The NAIC figure above reflects what Americans actually paid for this combined package, making it a more grounded benchmark than rate quotes from commercial comparison sites.
Why Our Average Differs from Other Sites
Commercial insurance sites often report national averages between $180 and $220 per month. The difference is not an error. Those sites typically use rate quotes (what insurers offer new customers shopping for coverage), while the NAIC reports actual premiums paid by all insured drivers, including those with loyalty discounts, bundling discounts, and other reductions. Quotes tend to skew higher because they reflect prospective risk pricing. Actual premiums reflect the full range of real-world pricing. We use the NAIC figure because it represents what people actually pay, not what they are offered. See our full methodology for how we adjust NAIC data to current dollars.
What the Coverage Gap Means for You
The $78/month gap between full and minimum coverage buys meaningful protection. Minimum coverage pays only the other party's expenses when you are at fault. If your car is damaged (in any scenario), you pay out of pocket. For a vehicle worth $15,000 or more, collision and comprehensive coverage typically pays for itself the first time you need it. For older vehicles worth less than $4,000, the math often favors dropping collision and comprehensive, since the maximum payout would be less than a year of premiums.

Frequently Asked Questions
What is the average cost of car insurance?
The average cost of car insurance in the United States is $150 per month ($1,803 per year) for full coverage in 2026, based on NAIC data adjusted for inflation. Minimum coverage (liability only) averages $72 per month ($866 per year).
What is the difference between full coverage and minimum coverage car insurance?
Full coverage includes liability, collision, and comprehensive insurance, while minimum coverage is liability only (the legal minimum your state requires). Full coverage costs about $78 more per month ($937 per year) but protects your own vehicle in addition to covering the other party's expenses.
Why is the NAIC average lower than what other sites report?
The NAIC reports what consumers actually paid in premiums, while many commercial sites report rate quotes (what insurers offer new customers). Rate quotes are typically higher because they include prospective pricing for risk, while actual premiums reflect discounts, bundling, and loyalty pricing that existing policyholders receive.
