Your premium isn’t a judgment on how you drive. It’s a calculation, built from a fairly short list of rating factors, and you can see most of them yourself before you ask anyone for a quote. That’s why two drivers with the same car on the same road can be charged very different amounts.
We care just as much about the factors you can’t touch. If your garaging zip code and your claims history are carrying more weight than anything you could change this week, knowing that beats one more list of tips.
Who we’re writing for
Anyone in the US who has opened a renewal notice and wondered where that number came from. You won’t need insurance know-how. Each breakdown just assumes your policy documents are close by and that you’d like to know which parts of them are pushing your price around.
What you’ll find
- What Moves a Premium: which rating factors insurers use, roughly how much weight each carries, and why neighbors with identical cars get charged differently.
- Factors You Can Change: your deductible, the mileage you declare, how you pay, and keeping your coverage unbroken.
- Comparing Quotes: why two quotes for one car rarely agree, which coverage lines to match up first, and how to catch a cheap quote that’s leaving something out.
You can browse all of them on the Breakdowns page.
How a breakdown works
One factor at a time. We say what it is, run it through an everyday example to show how it shifts a price, and name the choice it leaves you with, even when that choice is simply to wait. Since each state’s rules and each insurer’s rates vary between readers and over time, we stick to how pricing tends to work. When a regulator in your state or an industry group has already explained something well, we’ll send you there.
Articles get revisited whenever the rules or the usual practice shift. Spotted something outdated or confusing? Drop us a line and we’ll check it.
Things we won’t do
- Sell you insurance, quote you a premium, or act as your agent or broker.
- Rank insurers or recommend one over another.
- Give legal advice about claims or disputes.
How we make money
A few pages and emails carry partner offers, including a free form that compares quotes, and we may get paid if you take one up. That doesn’t change what any breakdown says, and who might pay us never changes how we write about a factor.

One honest caveat: we’re explaining how US car insurance works in general, so none of it can speak to your specific coverage, a claim you’ve made or your particular situation. What’s covered, how programs run and what the law requires all shift over time, and they differ between insurers and between states. Please run anything that matters past your insurer or the appropriate regulator before you lean on it.
