How to Check the Financial Strength Rating of an Insurance Company

I almost signed a three-year commercial property policy before someone at my co-working space asked a single question: "Did you check their AM Best rating?" I had not. Fifteen minutes of searching later, I found the carrier had a B+ grade with a negative outlook — not disqualifying on its own, but enough for me to call my broker, ask some pointed questions, and ultimately switch to a different insurer. That lookup cost me nothing and probably saved a lot of stress. Here is exactly how to do it yourself.

What a Financial Strength Rating Actually Means

A financial strength rating (FSR) is an independent assessment of how able an insurance company is to meet its ongoing claims obligations. Think of it as a credit score for the insurer, not for you. Rating agencies examine things like the company's reserve levels, investment portfolio quality, reinsurance arrangements, and overall balance sheet health.

What it is not is a review of the company's customer service, pricing, or claims handling speed. Plenty of A-rated insurers have grumpy claims departments, and a few lower-rated ones are genuinely pleasant to deal with. The FSR is a narrow, specific signal: can this company likely pay a valid claim even if a large catastrophe hits, or if the economy turns sharply? That question matters most for long-tail policies — long-term care, life insurance, or large commercial lines where you might not file a claim for decades.

For shorter-term personal policies like annual auto or renters insurance, the risk of an insurer becoming insolvent between policy inception and your claim is lower. Still, checking the rating is a two-minute task that gives you a data point most buyers skip entirely.

The Four Major Rating Agencies You Should Know

Four agencies dominate insurance financial strength ratings, and each uses a slightly different scale and methodology. Knowing which one to start with saves time.

• AM Best — The only agency focused exclusively on insurance. Its FSR scale runs from A++ at the top down through A+, A, A-, B++, B+, B, B-, C++, C+, C, C-, D, E, and F. For most consumers buying personal lines, AM Best is the first and often sufficient stop.
• S&P Global Ratings — Uses the familiar AAA through D scale. S&P rates a broad range of companies, so its insurance ratings sit within a larger corporate-credit framework. The public site requires free registration to view most ratings.
• Moody's Investors Service — Uses Aaa, Aa, A, Baa, Ba, B, and so on, with numeric modifiers (1, 2, 3). More common in institutional and large commercial contexts than in personal lines research.
• Fitch Ratings — Similar AAA-to-D structure to S&P; widely used in Europe and for global reinsurers. Worth checking if your insurer is a subsidiary of a European group.

My honest take: unless you're buying a whole-life policy or a large commercial umbrella, AM Best alone covers the bases. Cross-reference with S&P if the policy runs longer than five years or if you find anything that makes you uneasy.

How to Look Up a Rating Step by Step

The lookup process is simpler than most people expect. Here is the step-by-step for AM Best, which has the most accessible free tier.

1. Go to ambest.com and click "Ratings." You do not need an account for basic FSR lookups. The public search box is right on the ratings homepage.
2. Search by company name. Type in the full legal name of the insurer as it appears on your policy declarations page — not just the brand name. Many large insurers have multiple subsidiaries (e.g., a parent group may have separate entities for auto, home, and life). Make sure you're looking at the right entity.
3. Read the FSR and the Outlook. The letter grade alone is not enough. An "A" with a "negative outlook" is worth less than a stable "A". A "positive outlook" on a B++ signals the agency expects improvement. These outlooks are one click away from the main rating page.
4. Note the date of the most recent review. A rating that hasn't been reviewed in 18 months in a volatile market is less reassuring than a freshly confirmed one.
5. Check S&P as a second opinion (optional but recommended for major policies). Visit spglobal.com/ratings, use the public search, and look for the insurer's Insurer Financial Strength rating specifically — distinct from its corporate credit rating.

For Moody's and Fitch, basic access typically requires a free account. The registration takes under three minutes and is worth it if you're comparing multiple carriers for a significant policy.

Decoding the Letter Grades: What A++, Baa2, and BBB+ Actually Mean

The letter scales look intimidating at first glance, but they map fairly cleanly to a handful of plain-English categories.

On the AM Best scale, anything from A- through A++ is considered "Secure" — these insurers have strong to superior ability to meet ongoing obligations. B++ and B+ are "Good" but sit one tier below secure. Once you drop below B+, you're in territory that most consumer advocates would flag as worth a closer look before committing.

On the S&P and Fitch scales, BBB- and above is investment grade. For insurance specifically, anything AA or above is exceptional; A-range is solid and common among mid-to-large carriers; BBB-range is acceptable for short-term personal policies but worth monitoring.

On the Moody's scale, the Baa2 I mentioned at the top of this section is the rough equivalent of BBB on the S&P scale — the lower end of investment grade. Anything Ba1 or below is considered non-investment grade, which does not mean the company is about to fail, but it does mean the agency sees meaningful uncertainty in its financial position.

One nuance worth knowing: a company can carry different ratings from different agencies for the same entity. Small divergences (one notch) are normal and reflect different weighting in methodology. A two-notch-or-more gap is worth investigating — sometimes it reflects a specific concern one agency weights more heavily.

Red Flags: When a Rating Should Make You Think Twice

A low grade is the obvious warning, but there are subtler signals that deserve attention:

• Rating on "Under Review" or "Watch" status — This means the agency is actively reassessing and a change is likely imminent. It's not necessarily bad (a positive review could result in an upgrade), but it's worth waiting for the resolution before committing to a multi-year policy.
• Recent downgrade without a clear recovery narrative — A single downgrade in isolation is less alarming than a pattern of two or three in quick succession. Look at the rating history, which AM Best shows on the company's public page.
• Withdrawal of rating — If an agency has withdrawn its rating on a company (often noted as "NR" or "Rating Withdrawn"), it frequently means the company stopped cooperating with the rating process. That itself is a yellow flag.
• Very small company with no rating at all — Some regional specialty insurers are simply too small for the agencies to rate. This doesn't mean they're bad — many are financially sound — but you'd want to check their state regulator filings and NAIC data instead.

A useful cross-check that most articles skip: look up the company's complaint ratio on the NAIC Consumer Information Source. A financially strong insurer with an unusually high complaint index is a different kind of risk — the kind you feel when you actually file a claim.

My Own Experience Checking a Rating Before Buying a Policy

Going back to that co-working space conversation: when I pulled up the carrier's AM Best page, the B+ grade with a negative outlook wasn't the only thing I noticed. The last rating action had happened eight months earlier following a significant hurricane season, and the agency's notes mentioned higher-than-expected catastrophe losses. The company hadn't been downgraded yet, but the direction of travel was clearly uncomfortable.

I called my broker and asked two direct questions: what is the reinsurance structure on this policy, and has any other agency changed their view of this carrier in the past year? Within 24 hours I had answers — one agency had quietly placed them on watch, which I wouldn't have found without specifically asking. We moved the policy to a carrier with a stable A rating. My premium went up by about eight percent, roughly $340 a year. That felt like a reasonable price for not wondering, every hurricane season, whether my insurer would still be solvent when I needed them.

The lesson I took from it: the rating lookup is only the start of due diligence. The outlook, the recent history, and a one-question conversation with your broker complete the picture. None of it takes more than half an hour, and this information is genuinely public — the agencies want you to use it.

Frequently Asked Questions

Is AM Best the only rating agency I need to check?
For most personal lines (auto, home, renters), AM Best alone is a solid starting point because it focuses exclusively on insurance. For large or long-duration policies, cross-referencing with S&P's insurer financial strength ratings adds a useful second opinion.

Can I check an insurance company's rating for free?
Yes — AM Best's basic FSR lookup is free without an account. S&P and Moody's require free registration for full detail. Your state insurance department and the NAIC Consumer Information Source offer additional data at no cost.

What is the minimum acceptable financial strength rating?
Most independent consumer guides suggest A- or above on the AM Best scale for standard personal policies. This is general guidance, not a hard rule — your risk tolerance and the duration of the policy both factor in. This article is general information, not professional financial advice, and your situation may differ.

How often do ratings change?
Agencies formally review ratings on a regular cycle, typically annually, but can issue interim actions — watches, outlooks, or emergency downgrades — at any time. Checking before you sign and once a year at renewal is a reasonable cadence.

Does a high rating guarantee my claim will be paid?
No. A strong FSR means the company is financially able to pay claims; it says nothing about whether your specific claim falls within policy terms. Read your policy carefully and understand what is and isn't covered regardless of the rating.

The short version: pull up ambest.com, search the legal name of your insurer, read the grade and the outlook, check the date of the last review, and ask your broker one direct question if anything looks off. It is a fifteen-minute habit that most policyholders never build — worth bookmarking this guide before your next renewal comes around.
