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

Q: Is Costco or Erie 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 Erie's $1,842/yr. The only way to know is to quote both.

Q: Which handles claims better, Costco or Erie?

Neither has a clear edge. Costco scores Not rated and Erie 743/1,000 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 Erie 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. Erie scores 4.2 out of 5. Compare them on the individual categories above, and on the quotes you actually get.

Q: Can I switch from Costco to Erie 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.

Erie

Across our six scoring categories, Costco comes out ahead in 0, Erie in 2, 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. Erie 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 Erie across all six categoriesScored 1–5. Longer is better in every category — the price bar already accounts for cheaper being better.

CostcoErie

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 Erie's $1,842/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.

Erie

$1,842 a year for full coverage, 22% below the national average — third-cheapest here and the cheapest available without a military or membership restriction beyond geography.

Claims satisfaction

Too close to call

Neither pulls ahead on claims satisfaction: Costco posts Not rated and Erie 743/1,000, 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.

Erie

743 out of 1,000, the highest score of any ranked insurer in the J.D. Power 2025 claims study and 43 points above the segment average.

Costco

Financial strength

Too close to call

Neither pulls ahead on financial strength: Costco posts A and Erie 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.

Erie

AM Best A (Excellent) — downgraded from A+ in September 2025 after multi-year surplus declines driven by weather losses.

Discounts

Erie ahead

Erie takes discounts on 11 published against Costco's 9 published.

Costco

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

Erie

Eleven published discounts, plus Rate Lock, which freezes your premium year to year even after a claim — a feature essentially nobody else offers.

Digital experience

Too close to call

Neither pulls ahead on digital experience: Costco posts Not published and Erie 4.38 iOS / 2.9 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.

Erie

4.38 on the App Store and just 2.9 on Google Play. Erie's app is the weakest in this review and the gap between platforms is severe.
