American Family vs Costco: which is better for car insurance in 2026?
Across our six scoring categories, American Family comes out ahead in 2, Costco in 0, 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. American Family 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.

Category by category
Price
Too close to callCostco does not release public rate data, so there is no like-for-like premium to set against American Family's $2,785/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.
$2,785 a year for full coverage, 18% above the national average. American Family is priced above the market.
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 callNeither pulls ahead on claims satisfaction: American Family posts 702/1,000 and Costco Not rated, a difference too small to choose on.
702 out of 1,000, two points above the segment average. Essentially average.
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.

Nine published auto discounts, counting the member discount itself. No usage-based program is offered through Costco.
Digital experience
Too close to callNeither pulls ahead on digital experience: American Family posts 4.72 iOS / 3.0 Android and Costco Not published, a difference too small to choose on.
4.72 on the App Store but 3.0 on Google Play. That Android score is among the lowest in this review and hard to overlook.
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.
