Understanding Insurance Financial Strength Ratings

When shopping for car insurance, it's tempting to pick the cheapest policy and call it a day. But price is only half the equation. The other half — one most consumers overlook — is whether your insurer can actually pay your claim when you need it most. That's exactly what financial strength ratings measure.

Three major agencies — AM Best, Standard & Poor's (S&P), and Moody's — independently evaluate insurance companies and assign ratings that reflect their financial health. Each uses its own methodology and scale, but they all answer the same core question: How well-positioned is this insurer to meet its obligations to policyholders?

The Three Major Rating Agencies Explained

Here's a side-by-side breakdown of how each agency's rating scales compare:

AM Best (The Insurance Specialist)

AM Best has been rating insurance companies since 1906, making it the oldest and most specialized rating agency in the industry. Their 16-level scale runs from A++ (Superior) all the way down to F (In Liquidation). For most consumers, any rating of A- or better is generally considered solid ground. Ratings are searchable for free at ambest.com.

S&P Global Ratings

S&P uses a 22-level scale, with AAA as the gold standard and D indicating default. Their ratings focus on an insurer's capacity to meet ongoing policyholder obligations. An S&P rating of A- or higher is widely considered financially sound for a personal lines insurer.

Moody's

Moody's evaluates insurers using a 21-level scale from Aaa down to C, with numeric modifiers (1, 2, 3) within each letter category. Their methodology closely mirrors bond rating systems and focuses on the insurer's ability to pay senior policyholder claims on time.

What Happens If Your Insurer Goes Bankrupt?

An insurance company going insolvent isn't just a theoretical risk — it happens. When an insurer becomes financially unable to meet its obligations, it enters court-ordered liquidation, operations are halted, and claim payments can be delayed or reduced. AM Best assigns an "F" rating to companies in liquidation, a stark signal that the company can no longer function normally.

For policyholders, the consequences can be serious:

• Pending claims may be delayed for months or even years
• New claims may receive reduced payouts or none at all beyond guaranty fund limits
• Active policies may be cancelled, forcing you to scramble for new coverage
• Any amounts above guaranty fund caps become general creditor claims against the insolvent insurer's remaining assets

This is why choosing an insurer based solely on the lowest premium is a gamble. A policy from a financially shaky company is only as good as that company's ability to pay — and if they can't, you may be left with little recourse.

State Guaranty Funds: Your Safety Net (With Limits)

Every U.S. state — plus Washington D.C. — has a state guaranty association that steps in when a licensed insurer becomes insolvent. These associations are funded by assessing premiums against other healthy insurers operating in the state, which may then pass those costs to policyholders.

Here's how typical coverage limits break down for life and health lines (property/casualty limits vary by state):

Important: For auto insurance (property/casualty), your state's guaranty fund operates separately from life/health associations. Most states cover auto claims up to $300,000 per claim, but limits vary. Check your state's Department of Insurance website or ncigf.org for exact figures.

Warning Signs of a Financially Troubled Insurer

You don't need a finance degree to spot red flags. Here are the signals that warrant a closer look before you commit to a policy:

1. Premiums Far Below the Competition

If a quote is more than 15–20% lower than comparable coverage from other reputable insurers, that's a warning sign. Insurers price policies based on actuarial data — a company pricing significantly below market may not have the reserves to cover future claims.

2. Declining Financial Ratings

A recent downgrade from AM Best, S&P, or Moody's is a serious red flag. Even if a company still holds a passing grade, the direction matters. A move from A to B+ signals deteriorating financial health.

3. High NAIC Complaint Ratios

The National Association of Insurance Commissioners (NAIC) publishes complaint ratio data for every licensed insurer. A ratio significantly above 1.0 may indicate systemic claim-handling issues — which can sometimes be linked to financial strain.

4. Difficulty Getting Basic Policy Information

A legitimate insurer should provide your policy documents, insurance ID cards, and verifiable contact information promptly. Difficulty accessing these basics is a red flag worth taking seriously.

5. Aggressive or Pressure-Based Sales Tactics

Insurers urging you to buy immediately — especially with threats that prices are about to jump — may be prioritizing cash flow over your best interest. Reputable companies don't pressure you.

Balancing Price with Financial Strength

Here's the honest truth: a cheap policy from a financially weak insurer isn't a bargain — it's a liability. But that doesn't mean you have to pay top dollar to be safe. There are plenty of financially sound insurers that are also competitively priced. The key is knowing how to filter your options.

Practical Steps to Find the Best Value

1. Set a floor of A- (AM Best) or A- (S&P) as your minimum acceptable financial strength rating before comparing prices.
2. Get at least three to five quotes from companies that meet that floor — you'll be surprised how much prices vary among stable insurers.
3. Factor in discounts — many financially strong insurers offer significant savings for bundling, safe driving, or good credit. See what affects car insurance rates for a full breakdown.
4. Consider usage-based programs — telematics programs from major, financially stable carriers can cut your premium by up to 40%. Learn more in our guide to cheap car insurance in 2026.
5. Re-evaluate annually — ratings change, and so do your options. The best deal this year might not be the best deal next year.

Frequently Asked Questions

What is the best AM Best rating an insurance company can receive?

The highest AM Best rating is A++ (Superior), which signals the strongest ability to meet ongoing policyholder obligations. Very few insurers achieve this top rating — companies like New York Life are among the select group that consistently hold it. For most consumers, any rating of A- or higher is considered financially solid and appropriate for purchasing coverage.

Are insurance companies required to be rated by AM Best or S&P?

No — financial strength ratings are voluntary. Insurers choose whether to be evaluated by rating agencies. A company with no rating isn't automatically unsafe, but the absence of a rating from any major agency should prompt further research through your state's Department of Insurance to verify the company's financial standing.

If my insurance company goes bankrupt, will I still be covered?

You'll have some protection through your state's guaranty association, which steps in to cover certain claims up to defined limits. However, payouts can take time, and amounts above the cap may not be fully recovered. This is why it's critical to choose a financially healthy insurer rather than relying on the guaranty fund as a fallback.

How often should I check my insurer's financial strength rating?

It's a good habit to check your insurer's rating at least once a year, especially at renewal time. Rating agencies continuously review and update their assessments, and a company that was highly rated when you bought your policy could have been downgraded since. Checking takes only a few minutes and could save you from a major headache later.

Does a higher financial strength rating mean better customer service?

Not necessarily. Financial strength ratings measure solvency and claims-paying ability — they don't evaluate how quickly claims are processed, how helpful agents are, or how easy the company is to work with. For a complete picture, pair financial ratings with NAIC complaint ratios and third-party customer satisfaction scores from sources like J.D. Power.
