The membership fee is the least interesting number in warehouse club math

Sixty-five dollars a year is easy to work out. What decides the question is whether the food gets eaten, and the USDA has put a number on that too.

by · · 8 min read

A Costco Gold Star membership costs $65 a year, and the Executive tier is another 65 dollars on top of it[1]. BJ's charges 60 dollars for Club and 120 for Club+[2]. Sam's Club lists 60 dollars, currently with a first-year promotional price of 25[4].

Go twice a month and the card costs 2.71 dollars a visit. That is the whole fee question, and it takes ten seconds. It is also not the question.

The number that actually decides it

The US Department of Agriculture put the value of food bought and never eaten at 371 dollars per person per year at the consumer level – 9.2 percent of what the average American spent on food that year[6]. In volume: 21 percent of the American food supply, about 90 billion pounds, is thrown away by consumers themselves[7].

Hold those two numbers next to each other. The membership is 65 dollars. The food already going in the bin is 371 dollars a person. Bulk buying moves the second number, and it can move it in either direction – a case of something you finish is a saving, a case of something that goes off is a purchase you made twice.

What nobody has measured

How much buying in bulk actually saves per dollar spent. No institution publishes it, so we are not going to put a percentage here. What exists is the retailers' own claim: BJ's tells its investors that members can save more than ten times the 60-dollar fee if they spend 2,500 dollars or more a year there on branded groceries[3]. That is a seller describing its own product, in a document written for shareholders, and it implies a saving rate roughly a quarter of the way up the receipt. Treat it as a claim, not a finding.

Assumptions behind this calculation

  • How often you actually use it comes from you. We assume no typical usage – that would be exactly the invented number this is about.

Loaded with the Costco fee, two visits a month, and five dollars as the saving per visit. That last number is yours to supply and it is the only one we cannot give you: no source measures it, and any figure we printed would be invented. Take one real receipt, price four or five of the same items at your usual store, and use the difference. It is twenty minutes and it replaces a guess with your own arithmetic.

The threshold that comes out is not a verdict either. If it says thirteen visits and you go twice a month, the card pays – provided the food is eaten. If it says thirteen visits and you go five times a year, it does not, and no amount of enthusiasm at the door changes that.

The honest counterweight to our own scepticism

92.3 percent of Costco members in the United States and Canada renew, and 89.8 percent worldwide[5]. That is a very high number for a product people pay for up front and can walk away from every year. Whatever the arithmetic looks like on paper, a lot of members have run it against their own receipts and concluded it works – and it would be dishonest to leave that out of an article that started sceptically.

The point is not that warehouse clubs are a trap. It is that the fee is the part everyone checks and the part that barely matters, while the part that decides it – how much of what you carry out actually gets eaten – nobody checks at all.

One thing the fee tier hides

The higher tiers cost double and pay a percentage back on what you spend. That turns the membership into a bet on your own annual spend at one retailer: below a certain figure the upgrade costs more than it returns, above it the reverse. It is exactly the sort of switch worth running through the switch calculator with your own last twelve months of receipts, rather than deciding at the counter.

What you can do about it

  1. Price five real items before you renew

    Take one receipt and check the same five things at your normal store. Not a website comparison of headline products – the specific items you actually buy, at the sizes you actually finish. That gives you the saving-per-visit number the calculator needs, and it is the only input in this article nobody can supply for you.

  2. Count the bin before you count the savings

    For two weeks, note what gets thrown out. Not to feel bad about it – to find out whether bulk perishables are a saving or a purchase made twice. If nothing is going out, buy in bulk with confidence. If half a bag of salad goes weekly, the club is not the problem and it is not the solution either.

  3. Split a membership, if the rules allow it

    Household cards and second cards exist, and the terms differ by club and change. Read the current membership terms rather than taking a friend's word from three years ago; where sharing is permitted, it halves the least interesting number in the calculation, which is at least tidy.

  4. Do not upgrade the tier on the strength of a percentage

    The higher tier pays back a share of what you spend, which means it only pays if you spend a great deal at that one retailer. Take your last twelve months, apply the rate, subtract the extra fee. If the answer is close, the upgrade is a bet on next year looking like last year – and it is much easier to say yes to at the counter than at the kitchen table.

Frequently asked

Why is there no figure for how much bulk buying saves?

Because nobody has measured it in a way we could cite. Retailers publish claims about their own value, comparison sites publish baskets chosen by the person building the basket, and neither is a finding. The calculator takes your saving per visit as an input for exactly that reason – the number exists, it is just specific to you and to what you buy.

The USDA food waste figure looks old.

It is: the per-capita dollar value is stated at 2010 retail prices in the ERS study, and we have not adjusted it, because adjusting somebody else's figure and presenting the result as theirs is how numbers drift. What it is good for is the proportion – roughly a tenth of food spending, a fifth of the supply – and proportions age better than dollar amounts.

If the fee barely matters, why lead with it?

Because it is the only part most people check, and the gap between what gets checked and what decides the outcome is the subject of this site. The fee is knowable in ten seconds and roughly irrelevant. The waste rate is invisible and decides everything.
