Costcoâs business model is called a subscription business model â customers who want to shop at the store must buy a membership (currently $55 in the U.S.) with the promise of lower prices to make up for the initial upfront cost.
Citing UBS analysts, Business Insider reported that Costco is due to jack up its membership fees sometime this year or early 2017 by roughly 10%. If and when the change comes, the cost of a basic membership will increase from $55 to $60 annually, and an executive membership would go from $110 to $120.
