How much emergency food to store (per person)
When people plan emergency food, they count cans. The better unit is calories: enough energy per person, per day, in food you will actually eat. Here is how much to store, and how to keep it from expiring in the back of a closet.
The target: think in calories
Plan for roughly 2,000 calories per person, per day as a working number. Active adults and teens may need more, small children less, so adjust for your household. Counting calories instead of cans keeps you from storing a shelf of one item and still coming up short.
How many days should you cover?
- 3 days is the minimum, and what belongs in a grab-and-go kit.
- 2 weeks is the recommended home target, since real disruptions often outlast three days.
- Longer supplies, a month or more, are a personal choice. If you go there, rotation matters even more.
How much that actually is
| Household | 3 days | 2 weeks |
|---|---|---|
| 1 person | ~6,000 cal | ~28,000 cal |
| 2 people | ~12,000 cal | ~56,000 cal |
| Family of 4 | ~24,000 cal | ~112,000 cal |
As a rough feel, 28,000 calories is around two weeks of canned meals, grains, and snacks for one adult.
What to stock
The best emergency food is shelf-stable, needs little or no cooking, and is food your household already likes:
- Canned proteins: tuna, chicken, beans.
- Peanut or other nut butter, and crackers.
- Rice, oats, and pasta, with a plan to cook them if the power is out.
- Canned vegetables, fruit, and soups.
- Energy and granola bars, dried fruit, and a few comfort foods.
- A manual can opener, the most-forgotten item on the list.
Do not forget
Account for dietary restrictions, baby formula, and pet food. Store a way to cook without power if your plan leans on rice or pasta, and keep some food that needs no heat at all.
The catch: storage only works if you rotate
A two-week supply is only real if it is not expired. The reliable approach is to buy what you normally eat, cook from your stockpile, and replace what you use, so the food keeps moving instead of aging on a shelf. Use whatever expires soonest first, and restock to the back.
Quick checklist
- Plan around 2,000 calories per person, per day.
- Cover three days minimum, two weeks at home.
- Stock shelf-stable food you actually eat, plus a manual can opener.
- Cover dietary needs, infants, and pets.
- Rotate: use soonest-to-expire first, restock to the back.
