Car Insurance Affordability by State: Where Auto Coverage Eats the Most Income
The useful state comparison is not just premium dollars. It is insurance spending relative to household income. Triple-I’s September 2026 index gives a current affordability lens.
The 2026 affordability picture
National affordability measure
Share of median household income reported by Triple-I. The index uses state-level data through 2025.
The 2020 bar is back-calculated from Triple-I’s statement that the latest 1.7% level is 9% higher than 2020, so it is an approximation for context, not a separately reported data point.

Triple-I points to different combinations of uninsured-driver exposure, claims litigation, repair costs and market conditions. That is why a state ranking should not be interpreted as a driver-specific quote.
Turn the state article into a shopping worksheet
For SEO visitors, the most useful CTA is not “the average is X.” Give them a four-column quote sheet: same liability limits, same comp/collision deductibles, same drivers/vehicles, then compare total premium and exclusions. An average can explain the market; only standardized quotes can answer what they should buy.
FAQ
Does the cheapest state mean every driver there pays less?
No. Age, location, driving record, vehicle, limits, credit-based insurance scoring where allowed, and other rating factors can dominate an individual quote.
Why use percent of income?
It distinguishes raw price from household burden.
How often should this page update?
At least when Triple-I/IRC or NAIC releases a new affordability dataset; the page should show the data year separately from the publication year.
Sources & methodology
We favor regulators, government agencies and primary insurance-industry data for factual rules and current limits. Calculators use the numbers you enter and clearly labeled illustrative assumptions rather than pretending a national average is your quote.
