Cheap Grocery List: Feed a Family of 4 for $100/Week

The USDA says a "thrifty" food plan for a family of four costs about $250/week. That's over $13,000 a year. Plenty of families do it for less than half that amount without resorting to ramen every night.

The trick isn't extreme couponing or driving to five different stores. It's building your meals around cheap, filling staples and buying everything else around them.

Here's a concrete grocery list, broken into categories, that feeds a family of four for roughly $100/week. Every item has an approximate price based on 2026 US grocery averages.

The Foundation: Cheap Staples

These items cost pennies per serving and form the base of almost every budget meal.

Subtotal: ~$26

These items last 1-2 weeks and provide the caloric base for most meals.

Proteins ($20-$25/week)

Subtotal: ~$23

Produce ($15-$20/week)

Buy seasonal and buy frozen when fresh is expensive.

Subtotal: ~$18.50

Dairy & Bread ($10-$12/week)

Subtotal: ~$12.50

Extras & Flavor ($8-$10/week)

Subtotal: ~$9

Grand Total: ~$89

That leaves $11 of buffer for the occasional treat, a forgotten ingredient, or a sale item worth stocking up on.

What You Can Make With This List

Breakfasts:

• Oatmeal with bananas and peanut butter
• Scrambled eggs with toast
• Rice porridge with egg
• Pancakes from flour, eggs, milk, and butter

Lunches:

• Bean and rice burritos with salsa
• Tuna sandwiches
• Egg fried rice with frozen broccoli
• Lentil soup (lentils, carrots, onion, garlic, canned tomatoes)

Dinners:

• Chicken thigh stew with potatoes and carrots
• Spaghetti with meat sauce (ground beef, canned tomatoes, pasta)
• Black bean tacos with cheese and salsa
• Baked chicken thighs with rice and broccoli
• Lentil curry over rice (lentils, canned tomatoes, spices, rice)

That's easily 5+ dinners, 5+ lunches, and 7 breakfasts for four people. Leftovers fill in the gaps.

How to Make This Even Cheaper

Buy in bulk at warehouse stores. Rice, beans, oats, and cooking oil are significantly cheaper in bulk. A 25 lb bag of rice at Costco costs about $12, which is $0.48/lb versus $0.70/lb in regular stores.

Watch for weekly sales on proteins. Chicken thighs and ground beef cycle through sales every 2-3 weeks. When they're on sale, buy double and freeze the extra.

Grow herbs. A $3 basil plant from the store produces $30+ worth of basil over its lifetime. Same with green onions (stick the roots in water and they regrow).

Don't buy pre-cut anything. A whole chicken ($6-$8) gives you more meat than two packs of chicken breasts ($12-$15) plus bones for stock. A whole block of cheese is cheaper per ounce than shredded.

Tracking What You Spend

The hardest part of grocery budgeting isn't the shopping. It's knowing where you actually stand. Most people underestimate their grocery spending by 20-30%.

Scanning your receipts after each trip and categorizing the items takes 30 seconds with a receipt scanning app. After a month, you'll see exactly which categories eat up your budget (pun intended) and where to focus your cuts.

Your Next Move

Print this list or save it to your phone. Try it for one week. If $100 feels tight, start at $120 and work down. The goal isn't to hit a perfect number on week one. It's to build the habit of planning meals, buying staples, and tracking what you spend. The savings compound from there.
