There are a few things to consider when thinking about the cheapest Costco membership. The first is whether or not you will be using the membership for personal or business purposes. If you plan on using the membership for business purposes, then you will need to purchase a Business Membership.
The business memberships start at $60 per year. If you are looking for a membership for personal use, then you will need to purchase a Gold Star Membership. The Gold Star memberships start at $55 per year.
Another thing to consider is whether or not you want to add on any additional memberships. For example, adding a household member to your account will cost an additional $40 per year. You can also add on an executive membership, which will cost an additional $120 per year but comes with a few extra perks, such as 2% cash back on all purchases made at Costco.
Taking all of these things into consideration, the cheapest Costco membership would be the Gold Star Membership at $55 per year. However, depending on your specific needs, there may be a better option for you.
