Is this a government site?

No. PremiumTally is published by Inventum, an Australian-registered company, and has no affiliation with any insurance regulator or government agency. Where a figure comes from an official document, that document is linked so it can be read directly.

Why is no insurance company ever named?

Because naming them would change what this site is. Republishing per-insurer filed rates turns a data reference into an insurer ranking, which is a marketing surface with an incentive to shade the numbers. Publishing only the distribution removes that incentive and keeps the framing honest: these are sample rates filed for a defined hypothetical driver, not prices offered to anyone.

Why is there no average car-insurance cost here?

Because the 13 regulators that publish premium data define their drivers, coverages, deductibles and policy terms differently, and 38 jurisdictions publish nothing usable at all. An average across them would depend mostly on which surveys happen to exist.

How current is the data?

It varies by source and every page says so. The oldest survey is Arizona, rates effective March 2023; the newest is Maryland at August 2026. The price index refreshes with each release, most recently for June 2026.

About PremiumTally

PremiumTally is a data reference. It publishes what state insurance regulators have already published about car-insurance premiums, recomputed into a form a reader can use, alongside the statutory requirements of every US jurisdiction read from the statutes themselves.

What this site publishes

Three layers of data, and nothing else. The first is premium data, from 13 state regulators that each run a survey in which insurers file sample premiums for hypothetical drivers the regulator itself defines. We archive those documents and compute a distribution for every geography and profile the regulator published. Behind the 18,789 cells committed so far sit 744,460 individually filed rates.

The second layer is statutory. Each of the 51 US jurisdictions gets a requirements page built from the statute that sets its minimum liability limits, its tort system and its rating rules, with the citation and effective date attached to each figure.

The third is the federal price index: the U.S. Bureau of Labor Statistics motor-vehicle-insurance component of the Consumer Price Index, series CUUR0000SETE. It is the only national number here, because it is the only one that is measured rather than assembled.

In the first batch that comes to 369 pages: 117 geography pages, 142 driver-profile pages, one requirements page per jurisdiction, 10 cross-state rule tables, and the reference pages around them.

What this site refuses to publish

The refusals define the site more than the inventory does, so they are stated plainly and enforced by build gates rather than by good intentions.

No insurer is ever named. Not in a table, not in prose, not in a footnote. Every source document names insurers and prints their filed premiums; we publish only counts and distribution statistics computed from them.
No ranking, no answer to the question of which company, and nothing a reader could mistake for a price offered to them.
No national average car-insurance cost. The regulators define their hypothetical drivers so differently that a national figure assembled from them would measure the mixing rather than the market.
No recommendation. Copy states what the data shows. It never tells a reader what to buy or which coverage to choose.
No lead generation of any kind: no quote forms, no affiliate links, no phone numbers, no third-party widgets. The only outbound links anywhere on the site go to the regulator that published the data, to the statute, or to the Bureau of Labor Statistics.

Who publishes it

PremiumTally is published by Inventum, an Australian-registered company. The site covers US data and is written for a US reader, but it is not a US-based publication, and it is not affiliated with, endorsed by, or acting on behalf of any insurance regulator, government agency or insurance company. Nothing here is official and nothing here carries authority beyond the documents it cites.

Pages are attributed to PremiumTally Editorial, the brand as author. There are no personal bylines by policy. The work is dataset construction and verification rather than opinion, and the thing worth holding to account is the pipeline: every figure names the regulator that published it, that regulator’s own definition of the driver, the date the rates took effect, and the number of filed rates behind it. That is a harder claim to make than a name, and an easier one to check.

Corrections, source suggestions and permission requests go to support@inventum.com.au.

How the site is paid for

PremiumTally is supported by display advertising. That is the whole model: no subscriptions, no sponsored placements, no paid inclusion, no affiliate revenue, no relationship of any kind with an insurer.

Advertising has no influence over which figures are published, and the reason is structural rather than a promise. The figures are computed at build time from committed source documents by code in this repository. Nobody selects them. An advertiser cannot move a median, because no person sets a median on this site.

Ad units are kept away from the data as well. No advertisement sits between a tool’s input and its result, and no interstitial ever covers a tool.
