When you’re on a tight budget, maximizing calories per dollar is key to stretching your food dollars. Whether you’re a college student, a frugal shopper, or preparing for emergencies, knowing which foods give you the most energy for the least money can make a huge difference.

In this guide, we’ll break down Walmart’s cheapest foods by cost per calorie, so you can stock up without breaking the bank.

Why Cost per Calorie Matters

Calories = energy, and some foods pack far more energy per dollar than others. While nutrition is important, this list focuses purely on affordable calorie sources—perfect for supplementing a budget diet or emergency stockpiling.

(Note: Many of these foods lack balanced nutrition. Pair them with vegetables, proteins, or vitamins for a healthier diet.)

Top 10 Cheapest Foods per Calorie at Walmart

Best Ways to Stretch These Foods Further

• Store properly (keep flour, rice, and beans airtight to prevent pests).

Final Thoughts
