How many people are in your household, and how much do you cook at home?

Family of four or more, or 2-3 of us who cook at home a lot; Couple or 2-3 of us who cook sometimes; Single, or a couple who eats out often and barely cooks

How far is the nearest Costco?

Close — within about 15 minutes; Moderate — 20 to 40 minute drive; Far — 45+ minutes, or only practical on rare trips

Do you have storage space — pantry, garage, basement, freezer — for bulk groceries and paper goods?

Yes — garage, deep pantry, chest freezer, or otherwise generous storage; Some — I'd make it work but it'd be tight; No — small apartment, no garage, limited freezer space

How much driving do you do — and would you regularly fill up at Costco gas?

A lot — gas savings alone could justify the membership for me; Some — I'd use Costco gas occasionally; Not much — gas isn't a meaningful expense for me

Honestly, how disciplined are you with impulse buys at warehouses or big stores?

Disciplined — I'd come for chicken and leave with chicken; Pretty good, with some slippage; Not great — I tend to leave warehouses with way more than I planned

What specifically would you actually use it for?

Several things — groceries plus gas plus optical, pharmacy, tires, or travel; Mostly groceries and gas — the basics; Honestly not sure — I just keep hearing it's a good deal

Are there alternatives that already work for you — Sam's Club, BJ's, Amazon Prime, a great local grocery?

Not really — Costco would fill a gap for me; Some, but Costco still seems worth trying; Yes — I already have alternatives I'm happy with

Whether you should get a Costco membership comes down to four practical factors: how big your household is (bulk math needs people to actually eat the bulk), how far you live from a store, whether you'll use Costco gas, and whether you have storage for everything you'd buy. For a family within a 15-minute drive who already cooks at home and tops up at Costco gas, the $65 Gold Star membership usually pays for itself many times over — Consumer Reports consistently ranks Costco among the cheapest national supermarkets in their basket-price comparisons, before you add gas savings, Kirkland house-brand quality, and the famously generous return policy. For a single person or couple in a small apartment 40 minutes away who doesn't really cook, it's mostly a long drive for things they'll throw away. The trap to watch is the 'Costco effect' — saving on individual items while overspending overall because bulk and impulse-buys ('I came for chicken and left with a kayak') eat the savings. Start with the basic Gold Star ($65); only upgrade to Executive ($130) once you know you're spending more than about $3,250 a year on rewards-eligible purchases, since that's where the 2% cash-back actually clears the extra fee — and the 2% reward is capped at $1,250 per year, so heavy spenders hit that ceiling around $62,500 in annual spend.
