Car insurance company ratings come in three main types: financial strength ratings, which measure whether an insurer can pay its claims; customer satisfaction surveys, which capture how policyholders feel about their experience; and complaint ratios, which show how often customers complain to state regulators relative to the company’s size. No single rating tells the whole story, so the smart move is to check all three types together. Here’s how each one works and how to combine them into a clear picture.
Why Ratings Matter When Choosing an Insurer
When you buy car insurance, you’re buying a promise: that the company will be there with money when you need it. Ratings are the closest thing you have to an outside check on that promise. Financial agencies evaluate an insurer’s balance sheet, independent surveys capture real customer experiences, and state regulators publish hard data on complaints. Together, these sources do something marketing can’t — they give you an evidence-based view of the company behind the quote.
Ratings are especially useful because you can’t test claims service until an accident happens. They let you benefit from millions of other policyholders’ experiences and from analysts who study insurers’ finances full time. See our guide to how to choose a car insurance company for how ratings fit into the bigger picture.
Financial Strength Ratings
Financial strength ratings are issued by independent rating agencies that analyze insurance companies’ ability to meet their financial obligations — in plain language, whether the insurer has the reserves and stability to pay claims, even in a bad year. These agencies review balance sheets, investment portfolios, operating results, and business profiles, then assign a letter-grade rating.
What the grades mean in practice
Each agency uses its own scale, but the structure is similar: top grades indicate exceptional or superior ability to meet policyholder obligations, middle grades indicate adequate or good ability, and lower grades signal vulnerability to adverse conditions. You don’t need to memorize every notch on every scale. The practical rule is simple: prefer insurers whose ratings sit comfortably in the upper portion of the scale, and be cautious about companies with ratings near or below the “vulnerable” range.
Check ratings from more than one agency when you can. Agencies weight factors differently, so a company rated strongly by two or three agencies is a safer bet than one rated strongly by a single source. Note the rating’s outlook if one is published: a stable outlook is reassuring, while a negative one suggests risks ahead.
How deep should you go?
For most shoppers, confirming a strong rating is enough. If you’re considering a smaller or newer insurer, our guide to checking an insurer’s financial strength walks through finding and interpreting ratings in more depth.
Customer Satisfaction Surveys
Customer satisfaction surveys ask large samples of policyholders to rate their insurers across categories like overall satisfaction, claims handling, billing, communication, and digital tools. Because these scores come from real customers rather than analysts, they capture the lived experience of being insured — hold times, clarity of explanations, and how a claim actually felt.
Reading survey results carefully
Pay attention to which categories score well or poorly, not just the headline number. A company might rank highly overall but score poorly on claims satisfaction — and since claims are the moment that matters most, that detail should weigh heavily in your decision. Look at scores across your region too; a company can perform well nationally and poorly in your state, or the reverse.
Also check consistency over time. A company that ranks near the top year after year shows something durable about its service culture. Use surveys mainly to compare the companies on your shortlist, not as an absolute pass-fail test.
Complaint Ratios
Every state insurance department collects consumer complaints against insurers and publishes the data, usually as a complaint ratio: the company’s share of complaints divided by its share of the market. A ratio of 1.0 means the company gets exactly the complaints you’d expect for its size. Above 1.0 means more than expected; below 1.0 means fewer.
Why complaint ratios are powerful
Unlike surveys, complaint ratios aren’t based on opinions — they count actual complaints filed with regulators. And unlike individual online reviews, they’re adjusted for company size, so a giant insurer isn’t penalized simply for having more customers. A consistently low complaint ratio is one of the strongest signals that a company treats its customers fairly.
Look at trends over several years rather than a single snapshot, and note the complaint types: claims-handling complaints matter more than billing disputes. Find this data on your state insurance department’s website or through the National Association of Insurance Commissioners, which publishes complaint data for cross-state comparison.
A Warning About Rating Scales
One of the most common rating mistakes is assuming every scale works the same way. It doesn’t. A “B” from one financial rating agency can mean something quite different from a “B” at another, and customer satisfaction scores use entirely different ranges from letter grades. Always read the scale you’re actually looking at — most rating publishers explain their scales on their websites.
Be careful with marketing too. Insurers sometimes advertise one flattering rating out of context — a top mark from a minor agency, or an old rating that hasn’t been updated. If marketing cites a rating, verify it at the source and check the date.
How to Combine the Three Types Into One Verdict
Here’s a simple process for turning ratings into a decision about any company you’re considering:
- Start with financial strength. Confirm a strong rating from at least one major agency. If the rating is weak, that’s usually enough to rule the company out — no amount of good service compensates for an insurer that might not be able to pay.
- Add the complaint ratio. Check the company’s ratio in your state. Below average is good; well above average is a warning sign worth taking seriously.
- Layer in satisfaction scores. Compare the company’s survey scores against the other insurers on your shortlist, paying special attention to claims satisfaction.
- Weigh the pattern. Strong across all three? That’s a company you can buy from with confidence. Mixed? Decide which weakness matters least to you — but don’t ignore a pattern where two or three signals point the same negative direction.
This takes less than an hour per company once you know where to look.
Rating Types at a Glance
| Rating type | What it measures | Where to find it | What “good” looks like |
|---|---|---|---|
| Financial strength | Ability to pay claims and meet obligations | Independent rating agencies’ published ratings | Upper-range grade from at least one major agency |
| Customer satisfaction | Policyholder experience with service and claims | National independent satisfaction surveys | Above-average scores, especially for claims handling |
| Complaint ratio | Complaints to regulators relative to market share | State insurance department websites | Ratio below 1.0, trending stable or improving |
Red Flags to Watch For
- No financial strength rating at all: Established insurers are rated. A company with no public rating from any agency deserves extra scrutiny.
- A rating that’s slipped: A downgrade, especially more than one notch, means analysts see real deterioration. Find out why before you buy.
- Complaint ratio far above average: Occasional bad years happen, but a persistently high ratio suggests systemic problems with claims or service.
- Great price, terrible ratings: An unusually cheap quote from a poorly rated company is a trade-off, not a deal. The savings evaporate the first time a claim goes badly.
- Ratings cited without a source or date: If you can’t verify a rating at its original publisher, treat it as marketing, not evidence.
Frequently Asked Questions
What is the most important type of car insurance rating?
Financial strength comes first, because an insurer must be able to pay claims for anything else to matter. After that, complaint ratios and customer satisfaction scores tell you how the company treats its customers. Use all three together rather than relying on any one.
Can I trust the ratings an insurance company advertises?
Verify them yourself. Companies sometimes highlight one favorable rating while omitting less flattering ones, or cite ratings that are out of date. Check the rating at the original publisher’s site, note the date, and compare across agencies before drawing conclusions.
Do small or regional insurers have ratings too?
Many do, though smaller companies may be rated by fewer agencies than national ones. If you can’t find a financial strength rating for a company you’re considering, that’s a gap in your research — either dig deeper or lean toward insurers whose ratings you can confirm.
How often should I recheck my insurer’s ratings?
Once a year at renewal is a sensible rhythm. Ratings change slowly, but a downgrade or a rising complaint ratio is exactly the kind of thing you want to catch before you renew for another term. Pair this habit with our advice to review your car insurance policy every year.
What to Do Next
Pick the two or three companies you’re most seriously considering and run each one through the three-part check: financial strength, complaint ratio, and satisfaction scores.
