3 Reasons Costco Has Membership Fees. Numerous critics say prices at Costco Wholesale Corp. (COST), the members-only, big box discount retailer, aren't competitive. Its membership fees â $55 per year for a basic card or $110 per year for a 2% cash back card â are also too high, they say. But Costco uses a subscription model of business for three reasons.
More than one-third of Costco shoppers pay $110 for an executive membership, which reimburses them 2% cash back on their purchases. To cover the cost of the extra $55, executive members have to spend a minimum of $230 per month, or $2,750 a year. Executive members who spend twice that earn enough to cover the full cost of membership. To reap the full benefit of up to $750 cash back, they have to spend $37,500 per year.
