Fact-checking car insurance headlines about percent increases

A headline percent almost never applies to your policy directly. It describes an index, an average, a set of filings or a panel of imaginary drivers, over a particular period, and your own change depends on your insurer, your coverage and your rating factors. To use a headline, find what was measured, over what dates, for whom, and then compare it with your own renewal notice. This article gives a checklist, runs it on five representative claims built from real source documents, and ends with a way to turn a national figure into a personal estimate.

The five headlines below are composites written for this article, not quotations from any outlet. The numbers inside them come from the sources named, as of November 2026.

A nine-point checklist

Run every claim through these questions before you believe it or repeat it.

The how to read car insurance rate studies and average-cost claims guide covers the same ground in a shorter form, and reading auto insurance studies by who paid for them looks at who pays for the research.

Headline 1: "Car insurance prices jump more than 22% in a year"

Source: the Bureau of Labor Statistics (BLS) consumer price index for motor vehicle insurance. I pulled the not-seasonally-adjusted series for the U.S. city average.

Does the number hold up? Yes, with a date attached. The year-over-year change reached 22.6% in April 2024, the highest reading in the 2020-2026 data I pulled, and was 20.3% for the year to December 2023. A headline using it is accurate for that month.

What the index measures. The BLS fact sheet says the index covers physical damage, liability and miscellaneous coverage for private passenger vehicles. BLS follows selected policies with the driver and vehicle characteristics held fixed, and it uses premiums calculated for those unchanging characteristics, not the premiums people actually pay, because real policies change. Premiums are collected monthly, and the sample vehicles' model years are updated once a year.

What it does not measure. It is not what a typical household's bill rose by. People who respond to price increases by raising deductibles or dropping coverage see a smaller bill increase than the index shows. The National Association of Insurance Commissioners (NAIC) makes exactly this point, which is the next headline.

Checklist result: percent only, baseline is the same month a year earlier, population is the BLS sample of policies, coverage is held constant, national scope. Convert it by comparing the index with your own renewal percent, not by applying 22.6% to your bill.

Data note. The BLS data for October 2025 carry a footnote saying data were unavailable because of the 2025 lapse in appropriations, and the series I pulled has no value for November 2025, so year-over-year comparisons for those two months are missing.

Headline 2: "Americans now pay $1,281 a year for car insurance, up 14%"

Source: the NAIC's Auto Insurance Database Report for data years 2019 through 2023. Its state average expenditure table shows a countrywide 2023 figure of $1,281.92 against $1,124.57 for 2022, and the report text calls it an increase of 13.99%.

Does the number hold up? Yes, and the report explains what it is. Average expenditure is total written premium for liability, collision and comprehensive coverage divided by liability written car-years, an estimate of what consumers in a state spent on average. The report assumes every insured vehicle carries liability but not necessarily collision or comprehensive. It also warns that the calculation makes no distinction between policyholder classes, vehicle types, limits or deductibles, and it cautions readers to treat comparisons between states with a high degree of care.

Two official numbers for the same year. The same NAIC report shows the BLS price index for auto insurance rising 20.30% in 2023, while average expenditure rose 13.99%. The NAIC's explanation is that the price index holds the amount of insurance constant, whereas average expenditure is affected by choices consumers make about the types and amounts of coverage they buy. As prices rise, buyers reduce coverage or raise deductibles, so expenditure rises less than price. Neither number is wrong. They answer different questions.

Mean versus median. The report gives a countrywide average expenditure of $1,281 in 2023 and a median state average expenditure of $1,114. That is a median across states, not across drivers, but it shows how much the distribution matters: the countrywide mean is pulled up by high-cost states.

Regional skew. In the same table, Florida's 2023 average expenditure is $1,864.63, North Dakota's is $807.77 and Texas's is $1,428.94. A national average says little about any of those three. See average expenditure vs average premium vs quoted rate and What NAIC auto insurance data measures for the full explanation of how these measures differ.

Headline 3: "Full-coverage car insurance now costs an average of $X a month"

Source: typically a quote panel. Publishers buy rate data from a vendor and price an imaginary driver. Two examples show how much the choice of driver changes the result.

• Insurance.com's methodology page says its full-coverage averages use $100,000/$300,000 bodily injury and $100,000 property damage liability, $500 comprehensive and collision deductibles, a 40-year-old driver in a Honda Accord LX, good credit, a clean driving record and a 12-mile commute with 10,000 annual miles.
• LendingTree's methodology page says it obtains rates from the same vendor and describes a typical driver as a 30-year-old with a clean driving record and good credit.

Both pages name Quadrant Information Services as the rate source. Even with the same vendor, the two publishers define the driver differently, so their "average" figures are not comparable, and neither describes you.

Conflict of interest. LendingTree's page states that it is compensated by companies whose listings appear on its site and that this compensation may affect where and how listings appear. That statement is about the ratings and listings, not the rate averages, but it is the kind of disclosure to look for. The how car insurance comparison sites and lead generators work guide explains how these sites earn money.

Checklist result: the population is new-customer quotes for one profile, not what current policyholders pay. A panel average also tells you nothing about renewal pricing. Ask whether the headline discloses driver age, vehicle, limits, deductibles and credit. If it does not, the number cannot be checked.

Headline 4: "Insurers are asking for 25% increases"

This one is a hypothetical. The 25% is invented for illustration; the point is how to read any headline built on rate filings.

Source: rate filings that insurers submit to state regulators. A filing's requested change is an average across the insurer's policyholders in that state, and the amount a regulator approves can be lower. how car insurance rate approval works and loss ratios and rate filings: how insurers justify an increase explain the process.

What to check. Is the figure the requested change or the approved one? Is it for one insurer or the whole market? Is it a simple average of filings or weighted by premium? And what is the effective date? The from filing to your bill: the timeline of an auto rate increase article explains the lag between a filing and your bill.

A real contrast shows why. In an April 2026 announcement, the Pennsylvania Insurance Department said that PID-approved private passenger auto rate filings in 2025 averaged a 0.2 percent rate decrease, and that recent approved filings in 2026 averaged a 0.5 percent decrease, a $60 million reduction in proposed premium costs. It also said Pennsylvania drivers, like drivers nationwide, faced significant average rate increases from 2022 to 2024. That is a statement about approved filings, in one state, during a set period. It is not a statement about what any driver paid, because your premium depends on your own rating factors and on the insurer you have. The department itself says only that the stabilization could result in the same or a lower premium at purchase or renewal, not that it will.

Headline 5: "Car insurance prices fall 5% for the first time in years"

Source: the same BLS series as Headline 1, read at a different point. The year-over-year change was -5.1% in August 2026 and -5.0% in September 2026.

Does the number hold up? Yes, but the baseline carries the story. The index is still far above its earlier levels:

Two things follow from the table. First, the choice of baseline moves the long-run figure by about seven points, because the index fell during 2020. A "since 2020" number that starts in December 2020 begins from a dip. Second, the -5.0% is measured against September 2025. Prices fell from an early-2026 high, but they remain well above where they were three years earlier; September 2023 to September 2026 is +14.0%.

Percent math. A 5% fall does not undo a 5% rise. Prices that rise 5% and then fall 5% end 0.25% lower. A fall of 5% needs a rise of about 5.3% to get back. And percentages stack: the index rose 20.3% in 2023 and 11.3% in 2024, which compounds to about 33.9% over the two years, not 31.6%.

Turning a headline into a number for you

Use this procedure when a headline makes you wonder whether your own renewal is out of line.

1. Write down your own change. Take the last two renewal premiums for the same coverage and same limits, and compute the percent and dollar change. If your coverage, vehicle, address or drivers changed, the comparison is less clean; the renewal rate increase checker helps separate those causes.
2. Find the matching measure. If the headline cites the CPI, compare with the year-over-year change for the same month. If it cites NAIC averages, compare with the dollar level for your state, not the nation. If it cites a quote panel, compare with quotes you actually collect.
3. Check the baseline and the date. Make sure the headline's period matches yours.
4. Compute the gap. If your renewal rose 8% and the index rose 20% over the same 12 months, you did better than the index; if it rose 35%, ask your insurer which factors changed.
5. Ask for a reason. Your insurer can tell you what moved your rating: a surcharge, a rate-level change in your territory, a changed vehicle or mileage.
6. Get comparison quotes for identical coverage before you decide; the why your premium went up at renewal with no claims guide lists what to ask.

A worked example

Say your annual premium was $1,500 last year and your renewal notice says $1,740, with the same car, same limits and same address.

• Your change is $240, or 16%.
• Percent against dollars: a 20% headline applied to $1,500 would be $300. Your $240 is below that, but a 16% rise is still large, and the headline does not tell you why yours rose.
• Suppose a friend's premium was $900 and rose 20%, to $1,080. Her change is $180. Same percent, a very different dollar effect.
• Suppose a state average of $1,400 is in your report and your premium is $1,740. That does not mean you are overcharged. Your car, driving record, mileage and ZIP code may justify the gap. It is a reason to get quotes, not a verdict.

These figures are made up to show the arithmetic.

Common questions

Why do two reputable sources report such different percent increases for the same year?

Because they measure different things. The BLS index holds coverage constant and tracks price. NAIC average expenditure reflects what consumers actually bought, including cutbacks in coverage as prices rise. For 2023 they reported 20.30% and 13.99%.

Is the CPI number my premium increase?

No. It is a national index built from selected policies with fixed characteristics. Your change is driven by your insurer's rate changes and by your own rating factors. Compare, don't substitute.

Can I trust a quote-panel average?

It is useful for a rough sense of level when the publisher discloses the driver, vehicle, limits and deductibles. Without those details, treat it as marketing. Even with them, it describes new-customer quotes for one profile.

What if a headline cites a "study" and I can't find it?

Look for a named author, a date and a link to the data table. If you cannot trace it to a regulator, a statistical agency or a document with a methods section, discount it. Press releases that report only percents, with no base year, fail the checklist at the second item.

Key takeaways

• A headline percent describes an index, an average, a set of filings or a panel of imaginary drivers; it is not your premium change.
• The BLS price index and the NAIC average expenditure disagreed for 2023 (20.30% against 13.99%) because one holds coverage fixed and the other reflects what consumers bought.
• Baselines matter: the BLS index is up 47.7% from December 2019 and 55.1% from December 2020, and fell 4.8% during 2020.
• Quote-panel averages depend on the imaginary driver; Insurance.com and LendingTree define theirs differently.
• Convert a headline to a number by comparing it with your last two renewal premiums for identical coverage, and get quotes when the gap is large.
