How to Convert Oven Recipes to Air Fryer
This calculator helps you plan a balanced emergency food supply based on calorie targets and common storable foods. It creates a diversified plan across multiple food types.
The basic rule:
- Adults need 1,800–2,500 calories per day depending on activity level
- A balanced plan combines grains, proteins, fats, and freeze-dried meals
- Store foods with long shelf lives: rice (25+ years), beans (25+ years), honey (indefinite)
The calculator distributes calories across food types for variety and nutritional balance. Actual needs vary by age, gender, and activity. Always store what you eat and rotate stock regularly.

Frequently Asked Questions
How many calories per day do I need in an emergency?
The minimum for a sedentary adult is about 1,800 calories per day. For moderate activity (likely during an emergency), 2,000-2,500 is recommended. Children need 1,200-2,000 depending on age, and nursing mothers may need 2,500+.
What are the best foods for long-term storage?
White rice, dried beans, rolled oats, honey, peanut butter, and freeze-dried meals are top choices. When properly stored in mylar bags with oxygen absorbers, rice and beans can last 25+ years. Honey never expires.
How much does a year of emergency food cost?
A basic year supply of rice, beans, and oats for one person can cost $300-500. Adding freeze-dried meals, peanut butter, and variety brings it to $1,000-2,000 per person. Premium pre-made kits from brands cost $2,000-5,000 per person per year.
How much space does emergency food storage require?
A one-month supply for one person takes about 2-3 cubic feet. A one-year supply takes roughly 20-30 cubic feet per person (about the size of a large closet). Using #10 cans and 5-gallon buckets maximizes space efficiency.
What is a #10 can?
A #10 can is the large institutional-size can (about 6.25 inches wide by 7 inches tall) commonly used for freeze-dried and dehydrated food storage. Each can holds about 0.82 gallons and contains roughly 8-20 servings depending on the food type.
How should I store emergency food?
Store in a cool (50-70 degrees F), dry, dark location. Use food-grade containers, mylar bags with oxygen absorbers for bulk grains and beans, and keep canned goods off concrete floors. Label everything with pack dates and rotate using FIFO (first in, first out).
