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

Q: Is Costco or Shelter 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 Shelter's $1,749/yr. The only way to know is to quote both.

Q: Which handles claims better, Costco or Shelter?

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

Q: Is Costco better than Shelter 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. Shelter scores 3.9 out of 5. Compare them on the individual categories above, and on the quotes you actually get.

Q: Can I switch from Costco to Shelter 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.

CostcoNot scored

Shelter

Across our six scoring categories, Costco comes out ahead in 0, Shelter in 1, with 5 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. Shelter 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.

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

CostcoShelter

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 Shelter's $1,749/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.

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.

Shelter

$1,749 a year for full coverage, 26% below the national average — second-cheapest here behind MAPFRE.

Claims satisfaction

Too close to call

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

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.

Shelter

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

Complaint record

Shelter ahead

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

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.

Shelter

Fewer complaints than expected for its size.

Financial strength

Too close to call

Neither pulls ahead on financial strength: Costco posts A and Shelter A, a difference too small to choose on.

Costco

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

Shelter

AM Best A (Excellent). Its long-term issuer rating was downgraded a notch in October 2024 on underwriting performance, though the financial strength rating held.

Discounts

Too close to call

Neither pulls ahead on discounts: Costco posts 9 published and Shelter 9 published, a difference too small to choose on.

Costco

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

Shelter

Nine published discounts — but Shelter is the only carrier in this review with no usage-based program whatsoever, so there is no way to earn a discount by proving you drive well.

Digital experience

Too close to call

Neither pulls ahead on digital experience: Costco posts Not published and Shelter 3.35 iOS / 4.0 Android, a difference too small to choose on.

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.

Shelter

3.35 on the App Store across just 49 ratings, and 4.0 on Google Play across 424. The small Apple sample makes that score noisy.
