How It Works
This calculator creates a balanced calorie storage plan distributed across multiple food types for nutritional variety and practical storage. Each food contributes a percentage of total calories.
The basic rule:
- The plan allocates calories across 6 food types for nutritional balance and variety
- Calories per pound vary widely: rice at 1,650 vs peanut butter at 2,600 cal/lb
- All weights, costs, and space are calculated per food type and totaled
This calculator uses current average bulk pricing and standard storage densities. Actual costs depend on purchase source, quantity discounts, and regional pricing. Store all foods in proper containers for maximum shelf life.
Tips & Considerations
- Double-check your number of people before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both total calories needed and total weight — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to get accurate results.
- If you're unsure about your daily calories per person, start with a conservative estimate and adjust from there.
Frequently Asked Questions
How many calories per pound does rice have?
White rice has approximately 1,650 calories per pound (dry weight). It is one of the most calorie-dense, affordable, and shelf-stable foods for long-term storage. Properly stored in mylar bags with oxygen absorbers, white rice can last 25+ years.
What is the most calorie-dense food for storage?
Peanut butter is one of the most calorie-dense storable foods at approximately 2,600 calories per pound. Other calorie-dense options include oils (3,900 cal/lb), sugar (1,700 cal/lb), and rolled oats (1,700 cal/lb).
How much food do I need to store for one year?
For one person eating 2,000 calories per day for one year, you need approximately 730,000 total calories. Using a balanced mix of rice, beans, oats, and other foods, this works out to roughly 400-500 pounds of food total.
How much does a one-year food supply cost?
A basic one-year supply of bulk staples (rice, beans, oats) for one person costs approximately $400-700. Adding variety with peanut butter, honey, freeze-dried meals, and canned goods brings the cost to $1,000-2,500 per person.
What is the shelf life of each food type?
When properly stored: white rice 25+ years, dried beans 25+ years, rolled oats 25+ years, peanut butter 2-5 years, honey indefinitely (it never spoils), freeze-dried meals 25+ years. Proper storage means sealed mylar bags or #10 cans with oxygen absorbers.
How do I store food for maximum shelf life?
Use food-grade mylar bags with oxygen absorbers inside 5-gallon buckets for bulk grains and beans. Store in a cool (50-70 degrees F), dry, dark location. Label with contents and pack date. For shorter-term items like peanut butter, rotate using FIFO (first in, first out).
