How We Research Insurance Rates
Last updated: September 8, 2026
Every rate range, discount claim, and coverage explanation on QuoteCompareNow traces back to a public, checkable source. This page documents where those numbers come from, how our editors decide what is safe to publish, and what we refuse to do. If a page here cites a figure you want to verify yourself, this is the map.
Sources we use
- State insurance department filings. Every state publishes the rate filings insurers submit when they change premiums for defined driver profiles. Those filings, and the consumer guidance departments publish alongside them, drive our state-level and carrier-level commentary.
- Public complaint data. The National Association of Insurance Commissioners maintains a consumer information source, and individual state departments publish complaint counts by insurer and line of business. We use that material to describe service reputations qualitatively — not to manufacture a score.
- Insurer product disclosures. Public policy forms, endorsement wording, and coverage explainers from the insurers themselves. When we describe what comprehensive coverage pays for, we are describing what the standard policy form actually says.
- Independent industry research. Work from the Insurance Information Institute and comparable nonprofit and academic researchers is used where it materially shapes a range we publish.
- Published comparison benchmarks. To sanity-check national and state averages, we cross-reference benchmark methodology that comparison sites publish openly, and we discount for known bias — most obviously that their averages describe people who chose to shop, not all drivers.
Why we publish ranges, not exact rates
An individual auto premium turns on variables the driver never sees: insurance credit tier, ZIP-level loss history, prior coverage tenure, claims data, and how each company weights all of it inside a proprietary rating algorithm. Announcing that “the average driver pays exactly X” implies a precision that does not exist outside a specific quote.
So we publish ranges. A typical range on this site describes what a benchmark driver — mid-thirties, clean record, mid-tier credit, one moderately priced sedan, standard limits — would tend to see across several mainstream insurers in that state, built from public filings and cross-checked against published benchmarks. If your profile differs in any meaningful way, expect your real quotes to land outside our range in one direction or the other. That is not the range failing; that is how underwriting works.
What we do not do
- Take payment for favorable coverage. Advertisers and marketplace partners do not review or approve our content before publication and cannot change what a guide says.
- Publish a “best insurer” ranking. We describe what companies do well and where they draw criticism. Best is a function of your ZIP code, your profile, and what you value; a national ranking would be a guess dressed as a verdict.
- Publish a number without a source. If we cannot point to a public filing, a regulator's data, or published research, we describe the pattern in words rather than invent a figure.
- Chase the algorithm. We do not pad guides with keyword filler or restate a question five ways to lengthen a page.
How our editors work
A guide moves through the same stages before it goes live:
- Scoping. Our editors identify the single question the guide has to answer and the sources that can defensibly answer it.
- Drafting. An editor writes the guide from those sources.
- Number check. Every rate range, discount percentage, and timeline is checked against a second independent source before it survives the draft.
- Fact check. Claims about state law, minimum coverage requirements, and insurer practice are verified against primary sources rather than against other articles.
- Edit. A second member of our editorial staff edits for clarity, structure, and plain language, and strips anything that reads as advice rather than information.
- Publication. The guide goes live with an updated date.
- Review cycle. Guides are revisited at least annually, and immediately when a state changes a requirement or a market shift makes a range wrong.
Our calculators
The calculators on this site run entirely in your browser. They apply the arithmetic described on each tool's page to the figures you enter, and nothing you type is sent to us or stored. They are estimating aids for planning, not quotes; only an insurer can tell you your actual price.
How advertising fits in
QuoteCompareNow makes money when visitors request quotes through our links on a comparison marketplace operated by QuinStreet. That arrangement funds the research described on this page, and it is deliberately kept away from it: our compensation does not depend on which insurer a guide praises, so there is nothing to gain by shading a source. Full detail is on the disclaimer page.
