Chubb vs Costco: which is better for car insurance in 2026?

Q: Is Chubb or Costco cheaper?

We cannot answer that with published data. Costco does not release public rate information, so no independent study — ours included — can put a national average next to Chubb's $2,676/yr. The only way to know is to quote both.

Q: Which handles claims better, Chubb or Costco?

Neither has a clear edge. Chubb scores Not rated and Costco Not rated on the claims measure we use — close enough that the individual adjuster you draw matters more than the company average.

Q: Is Chubb better than Costco overall?

We can't put two scores side by side here. Costco does not publish enough of the underlying data for us to give it an overall score — we would rather say so than compute one from the two or three figures that do exist. Chubb scores 3.0 out of 5. Compare them on the individual categories above, and on the quotes you actually get.

Q: Can I switch from Chubb to Costco mid-policy?

Yes. Auto policies can be cancelled at any time, and most insurers refund the unused premium pro-rata — though some charge a short-rate cancellation fee, so check your policy before you cancel. The one rule worth following: get the new policy bound and in force before you cancel the old one. Even a single day uninsured can count as a coverage lapse, which raises your rate at the next renewal and, in some states, exposes you to a registration penalty.

Chubb

CostcoNot scored

Across our six scoring categories, Chubb comes out ahead in 1, Costco in 1, with 4 too close to call. There is no overall score to compare, though: Costco does not publish enough of the underlying data to earn one, and we would rather leave it blank than build a number out of the two or three figures that happen to exist. Chubb is the better-documented of the two, which is not the same as being the better insurer for you. Judge these two on the categories where both have real figures — and on what they actually quote you.

Chubb vs Costco across all six categoriesScored 1–5. Longer is better in every category — the price bar already accounts for cheaper being better.

ChubbCostco

Category by category

Price

Too close to call

Costco does not release public rate data, so there is no like-for-like premium to set against Chubb's $2,676/yr. That is a real gap in the comparison, not a rounding error — treat Costco's price as unknown until you have a quote in hand.

Chubb

$2,676 a year for full coverage on our standard benchmark, 14% above the national average — though Chubb's real book is valuable vehicles, not the Camry we benchmark with.

Costco

No published premium. The rate study behind every other price on this site does not quote Costco separately, so the price category carries no score.

Claims satisfaction

Too close to call

Neither pulls ahead on claims satisfaction: Chubb posts Not rated and Costco Not rated, a difference too small to choose on.

Chubb

Not in the J.D. Power claims study, which samples only the largest insurers.

Costco

Costco is not a ranked brand in the J.D. Power 2025 claims study. American Family's 702 is measured on a different book of business and is not borrowed here.

Complaint record

Chubb ahead

Chubb takes complaint record on Fewer than expected against Costco's More than expected.

Chubb

Fewer complaints than expected for its size.

Costco

More complaints than expected for its size, per NerdWallet's analysis of 2022–2024 NAIC data — a worse record than American Family's own brand.

Financial strength

Too close to call

Neither pulls ahead on financial strength: Chubb posts Not published and Costco A, a difference too small to choose on.

Chubb

An A++ rating for the Chubb group circulates widely and is very likely current, but AM Best and Business Wire both block automated access, so we could not read it from a primary page.

Costco

AM Best A (Excellent), affirmed in September 2025 for all three companies that underwrite Costco auto policies.

Discounts

Costco ahead

Costco takes discounts on 9 published against Chubb's 0 published.

Chubb

None. Chubb's own auto page names no discounts whatsoever — not a short list, an absent one. That is a deliberate positioning choice, not an oversight.

Costco

Nine published auto discounts, counting the member discount itself. No usage-based program is offered through Costco.

Digital experience

Too close to call

Neither pulls ahead on digital experience: Chubb posts 4.53 iOS / 3.6 Android and Costco Not published, a difference too small to choose on.

Chubb

4.53 on the App Store and 3.57 on Google Play. Only 306 iOS ratings across a 49-state footprint, which is itself evidence of how small and specialised the book is.

Costco

No app-store figures we could attribute to the program. Policies are serviced through American Family's account system, and we could not confirm which app Costco policyholders use.
