Costco can be a gold mine for retirees — or a money pit. The difference comes down to what you buy and how much of it you’ll actually use before it goes bad.

GOBankingRates asked ChatGPT to build the ideal monthly Costco budget for retirees, and its answer was surprisingly practical. The key, it said, is buying in bulk only where bulk makes sense and skipping the oversized traps that lead to waste.

How Much Should Retirees Spend at Costco?

ChatGPT suggested a monthly target of $250 to $400 for one or two people. That assumes you’re still hitting a regular grocery store for smaller or fresher items, not trying to get everything at Costco.

Where To Spend Your Budget

ChatGPT broke the budget into five categories.

Protein ($80 to $120) is where Costco earns its membership fee. Rotisserie chicken, salmon, chicken breasts, eggs and Greek yogurt all come at prices that beat most grocery stores. Buy in bulk and freeze what you don’t use right away.

For produce ($40 to $70), the advice was to be selective. Large fresh packs are risky because they spoil fast. Frozen vegetables are the smarter call for retirees since they last longer and create less waste.

Pantry staples ($60 to $100) are Costco’s sweet spot. Olive oil, nuts, rice, pasta, oatmeal and canned goods all keep for months, which means every dollar stretches further over time.

Freezer-friendly meals ($40 to $80) are worth keeping in rotation for low-effort nights. Frozen fish, shrimp, dumplings, and premade soups or lasagna make it easy to eat well without cooking from scratch every day.

Daily essentials ($20 to $30) round out the haul: coffee, milk, bread and butter. These are things you’ll always use, so buying in quantity makes sense.

What To Skip

ChatGPT was direct about what retirees should leave on the shelf. Giant fresh produce packs, snack multipacks, bulk baked goods and trendy seasonal items all carry a high risk of going to waste. If you’re not sure you’ll finish it, don’t buy it.

A Sample $300 Budget for Two People

ChatGPT mapped out a simple breakdown.

• Protein: $100
• Produce: $60
• Pantry staples: $80
• Frozen meals: $40
• Essentials: $20
• Total: $300

That haul, it said, can cover two to three weeks of meals when combined with a regular grocery store run. Think daily breakfasts (eggs, oatmeal, yogurt), simple lunches (salads, sandwiches) and easy dinners built around chicken, fish or pasta.

A Few Extra Tips

ChatGPT also flagged some habits that help retirees get the most out of a Costco membership. Shopping once a month cuts down on impulse buys. Splitting bulk items with a friend or family member helps when a package is just too large for one household. And the rotisserie chicken, it pointed out, is one of the best deals in the store because you can stretch it across multiple meals.

The bottom line: Costco works best for retirees when it’s used strategically, not as a one-stop shop. Lean into protein and pantry staples, use your freezer, and skip anything you’re not confident you’ll finish.
