When you actually sit down to build an emergency food kit, the vague advice — “store some food and water” — falls apart fast. How much? Of what? For how many people? This guide gives you concrete numbers: a real shopping list by category, with quantities, calorie and water math, and a clear path from a 72-hour kit to a full year of supply.
The two numbers that drive everything
- Calories: plan for roughly 2,000 calories per person, per day. Active adults and cold climates may need more.
- Water: store at least 1 gallon per person, per day — for drinking and basic cooking. More in hot climates or for anyone with extra needs.
For a family of four, a 72-hour kit means about 24,000 calories and 12 gallons of water. A 30-day supply for that same family is roughly 240,000 calories and 120 gallons. Those figures look big, which is exactly why freeze-dried ingredients shine: they pack enormous calories into a tiny, shelf-stable footprint.
Build to tiers, not all at once. Get a solid 72-hour kit first, then extend to two weeks, then a month, then beyond. Each tier is a real milestone of readiness.
The category checklist
A balanced kit covers every food group so you’re not living on crackers. Here’s what to include and why:
| Category | Why it matters | Examples |
|---|---|---|
| Fruits | Energy, vitamins, morale | Strawberries, bananas, apples, blueberries |
| Vegetables | Fiber, variety in meals | Corn, peas, broccoli, peppers, onions |
| Meats | Protein, satiety | Chicken, beef, sausage crumbles |
| Dairy & eggs | Protein, cooking, baking | Powdered milk, cheese, whole eggs |
| Staples & bulk | Calorie backbone | Rice, beans, oats, wheat |
| Snacks | Morale, quick energy | Freeze-dried fruit, trail-friendly bites |
The fastest way to cover all of these at once is with bulk and variety packs, which bundle multiple food groups into a single purchase sized for weeks or months.
Tier 1: The 72-hour kit (per person)
- ~6,000 total calories (2,000/day x 3 days) of freeze-dried ingredients and staples
- 3 gallons of water, plus a basic filter
- A mix from at least three food groups so meals feel like meals
- A manual can opener and a way to heat water

Tier 2: Two weeks to one month
Scale the 72-hour numbers up. For one person over 30 days, that’s about 60,000 calories and 30 gallons of water. At this tier, prioritize:
- A calorie-dense base of grains and beans
- Reliable protein from freeze-dried meats and eggs
- Enough fruits and vegetables to keep meals balanced and palatable
- A robust water and filtration plan, since storing 30+ gallons per person gets bulky
Tier 3: Three months to one year
This is long-term resilience. The math per person:
| Duration | Approx. calories/person | Approx. water/person* |
|---|---|---|
| 3 months | ~180,000 | ~90 gallons |
| 6 months | ~360,000 | ~180 gallons |
| 1 year | ~730,000 | ~365 gallons |
*Storing a year of water outright is impractical for most homes — this is where filtration and treatment become essential, paired with a stored reserve. Freeze-dried ingredients sealed in #10 cans last 20-30 years, so a year’s supply can sit ready for decades without rotation headaches.
Don’t forget the non-food essentials
- Water filtration and purification — see water
- Cooking and heat source, fuel, and a manual can opener
- Lighting, first aid, and off-grid tools from survival gear
- Shelter and portability items from camping & outdoor
Practical tips that save you grief
- Store what you’ll actually eat. A kit full of foods your family hates won’t get used.
- Keep it cool and dark. A closet or basement beats a hot garage for shelf life.
- Label and date. Even with decades of shelf life, knowing what you have prevents waste.
- Plan for cooking water. Rehydrating ingredients uses water — budget for it beyond drinking needs.
