Is a Costco membership worth it? The break-even math for 2026
A Costco membership is worth it when the money you save on what you buy there, minus whatever of it you end up throwing away, is more than the $65 fee. If Costco is 10% cheaper than your usual store and you waste 5% of what you buy, you need to spend about $1,300 a year there, or $108 a month, to break even. The $130 Executive membership beats the basic one once you spend more than $3,250 a year on qualifying purchases.
Everything else is detail, but the detail is where most memberships quietly stop paying: the discount is smaller than people think on the things they actually buy, and the waste is bigger.
What a Costco membership costs in 2026
Costco's annual report for the year ended August 31, 2025 sets out the US fees:
| Costco membership | Yearly fee | What it adds |
|---|---|---|
| Gold Star (or Business) | $65 | Shopping at Costco |
| Executive | $65 on top, $130 in total | A 2% reward on qualified purchases, up to $1,250 a year |
The same report says 92.3% of members in the US and Canada renewed, and that Executive members made up about 73.6% of Costco's sales worldwide. A few pages still quote a $60 fee or a $1,000 reward cap; neither matches the current annual report.
The break-even, worked out
Three numbers decide it, and only you know them:
- What you'd spend at Costco in a year.
- How much cheaper Costco is than where you'd otherwise buy the same things.
- What share of it ends up in the bin.
The membership pays for itself when spend × (discount − waste) is more than $65. So:
| Costco cheaper by | Waste | You need to spend a year | A month |
|---|---|---|---|
| 10% | 0% | $650 | $54 |
| 10% | 5% | $1,300 | $108 |
| 15% | 5% | $650 | $54 |
| 8% | 5% | $2,167 | $181 |
| 5% | 5% | never | never |
Our arithmetic. The last row is the one that surprises people: if you throw away as much as you save, no amount of shopping pays for the card.
Our warehouse club calculator does this sum with your own numbers, for Costco, Sam's Club or BJ's, and shows both membership levels side by side.
Is the Executive membership worth it?
The upgrade costs $65 and pays 2% of what you spend on qualifying purchases. It covers its own cost at $65 ÷ 2% = $3,250 a year, or about $271 a month. Below that, the basic membership is cheaper; above it, the Executive one is.
The cap only matters to heavy spenders: 2% reaches $1,250 at $62,500 of qualifying purchases a year.
The real break-even is a little higher than $3,250, because Costco pays the reward on qualified purchases and not everything you buy there counts. And the upgrade only answers which of the two cards is cheaper. If the basic membership doesn't pay for itself, fix that first.
How to find your own discount
The discount is the number people guess worst, because the big wins are memorable and the items that cost the same, or more, are not. Measure it instead:
- List the 10 or 15 things you'd actually buy there most often.
- Write down the shelf price and pack size at Costco and at your usual store.
- Compare them per ounce, per pound or per item. Our unit price calculator does the conversion.
- Weight the result by how much you buy of each.
A grocery price book is the same exercise kept up over weeks, and it's the best way to see whether a warehouse price beats your usual store's sale price, which is the fair comparison. For one item at a time, the bulk buy calculator sets a warehouse pack against a supermarket one, waste included.
Bigger packs aren't always cheaper per unit. Is buying in bulk cheaper walks through the evidence on that, and how to set a pack discount against what you'd waste.
Waste is what breaks it
A warehouse discount on a pack you don't finish is not a discount. The EPA puts the cost of food bought and not eaten at $728 per person a year, and big packs of perishables are an easy way to add to it.
The fix is to be strict about what goes in the cart:
- Buy big on things that keep for months: rice, pasta, oats, canned goods, frozen vegetables, coffee, oil, paper towels, detergent.
- Buy perishables there only when you have a plan for all of them, or a freezer for the rest.
- Keep a list of what you already have at home so the second pack of something doesn't come home by accident. Our pantry inventory list is a free printable for it.
Duneed, our iPhone app, builds that list from photos of your grocery receipts, with the price you paid for each line, so a warehouse run shows up both as what's at home and as what the month cost.
Is a Costco membership worth it for one person?
It can be, but the margin is thin. A person living alone on USDA's Moderate plan budgets about $405 to $478 a month for all groceries, which we work through in grocery budget for one person. If a third of that goes through Costco, that's roughly $1,600 to $1,900 a year, above the $1,300 break-even in the example only if the waste stays low.
For one person, the membership works best on non-perishables and household goods, and badly on fresh food. The Executive upgrade rarely pays: $3,250 a year of qualifying purchases is most of a single person's grocery budget.
For a couple and a family
The more people finish the big pack, the better the math gets. A couple on the Moderate plan budgets about $809 a month (grocery budget for 2 people); a family of four with school-age children about $1,391 (grocery budget for a family of 4).
A family that puts a third of a $1,391 month through Costco spends about $5,560 a year there. At 10% cheaper and 5% waste, the Gold Star membership comes out about $213 ahead, and the Executive one about $259 ahead, because the $111 reward is more than the extra $65.
Costco, Sam's Club or BJ's?
| Basic | Upper tier | Reward | Upper tier pays above | |
|---|---|---|---|---|
| Costco | $65 Gold Star | $130 Executive | 2%, up to $1,250 | $3,250 a year |
| Sam's Club | $60 Club | $120 Plus | 2% Sam's Cash, up to $750 | $3,000 a year |
| BJ's | $60 Club | $120 Club+ | 2%, up to $500 | $3,000 a year |

The fees are close enough that the fee shouldn't decide it. Which club is nearer, and which one sells the things you actually buy at a lower unit price, matters far more.
Common questions
How much do you have to spend at Costco to make the membership worth it?
It depends on how much cheaper Costco is for your basket and how much you waste. At 10% cheaper and 5% waste, about $1,300 a year covers the $65 fee. At 10% cheaper and no waste, $650.
Is the Costco Executive membership worth it?
If you spend more than $3,250 a year on qualifying purchases, yes: the 2% reward is then more than the extra $65. Below that, the Gold Star membership is cheaper.
How much is a Costco membership in 2026?
$65 a year for Gold Star or Business, and $130 for Executive, according to Costco's annual report for the year ended August 31, 2025.
Is Costco cheaper than a regular grocery store?
For many bulk items, often, but not for everything, and not always per unit. The only reliable answer is to compare your own list by unit price.
Should a single person get a Costco membership?
Only if they buy enough shelf-stable food and household goods there to cover the fee, and can finish or freeze what they buy. The basic membership is usually the right tier for one person.
