How Much Food to Store Per Person (Real Numbers)
It is the number-one prepper question, and most answers are vague. Here are real numbers. The floor is calories: about 2,000 a day for an adult. From there you scale to your goal, whether that is a 3-day kit or a full year of shelf staples. This guide gives you the per-day, per-year, and per-family math, then points you to a free calculator that does it for your exact household.

Start with the floor: about 2,000 calories per adult per day
Every food-storage plan starts with one number: daily calories. Public health guidance from sources like the USDA Dietary Guidelines uses roughly 2,000 calories a day as a common reference for an adult. That is your floor. Store less and people lose weight and strength fast, which is dangerous in an emergency when they need to work.
Calories are the floor, not the whole plan. A pile of white rice can hit your calorie target and still leave you short on protein, fat, and vitamins. Think of calories as the foundation, then build protein and nutrients on top. More on that below.
Adjust for real bodies. Active adults, teens, cold weather, and hard physical work push the number higher. Small children eat less. Count a young child as a partial share and bump it up as they grow.
- About 2,000 calories per adult per day is the standard planning floor.
- Active bodies, teens, and cold weather need more.
- Count young children as a partial share by age.
- Calories keep you alive, but add protein and vitamins for health.
Pick your target: 3 days, 2 weeks, 1 month, or 1 year
How much to store depends on how long you want to be covered. Most families should build up in stages instead of buying a year at once. Each stage below is a real, common target. Hit the first, then work toward the next.
The classic advice is to reach two weeks before you chase a year. A two-week supply covers most storms, outages, and short job gaps, and it is cheap and easy to rotate. A one-year supply is a serious project built on bulk staples, covered in the next section.
- 3 days (72-hour kit): the FEMA-style minimum. About 6,000 calories per adult. Grab-and-go food that needs no cooking.
- 2 weeks: the widely recommended baseline. About 28,000 calories per adult. Mostly canned and dry pantry food you already eat.
- 1 month: about 60,000 calories per adult. A deeper pantry plus some bulk staples like rice and beans.
- 1 year: about 730,000 calories per adult. Built on bulk grains, legumes, fats, and long-term storage methods.
The classic one-year bulk-staple framework
For a one-year supply, most preppers lean on a well-known bulk-staple list. These pound targets trace back to LDS and Provident Living food-storage guidance and university extension long-term storage guidance. Treat them as ranges and a starting point, not a law. They are cheap, calorie-dense, and store for years when sealed against moisture and oxygen.
The list below is per adult, per year. Scale it to your household and adjust to what your family actually eats. Grains carry most of the calories, legumes carry protein, and fats pack the most calories into the least space.
- Grains (wheat, rice, oats, cornmeal, pasta): about 300 to 400 lb.
- Legumes (dried beans, lentils, split peas): about 60 lb.
- Fats and oils (cooking oil, shortening): about 20 to 25 lb.
- Sugar or honey: about 60 lb.
- Dry milk (powdered): about 15 lb.
- Salt: about 8 lb.
Calories are the floor: add protein and vitamins
A pile of grain will keep you alive, but not well. Long-term stores built only on rice, wheat, and sugar can leave gaps in protein and key vitamins, and after weeks that shows up as fatigue and slow healing. The bulk framework already builds in legumes and dry milk for a reason: they cover protein the grains miss.
Round out the plan with protein and nutrient sources. Canned meat and fish, peanut butter, and dried beans add protein. Canned or freeze-dried vegetables and fruit, plus a simple multivitamin, help cover the vitamins that bulk staples lack. This is general information, not medical advice.
- Protein: canned tuna and chicken, dried beans, peanut butter, dry milk.
- Fat: cooking oil, shortening, nuts, peanut butter.
- Vitamins: canned or freeze-dried fruit and vegetables, plus a multivitamin.
- Variety fights appetite fatigue, which is real when the menu never changes.
Store it right so it lasts
Your numbers only hold if the food survives storage. Dry staples like rice, wheat, beans, and oats last for years when you keep three things out: moisture, oxygen, and light. Extension services note that oxygen and moisture control are what separate food that keeps for years from food that goes rancid or buggy in months.
For a renter or a small budget, you do not need a $2,000 freeze dryer to store bulk staples. Seal dry staples in Mylar bags with an oxygen absorber, drop the bags into food-grade 5-gallon buckets, and store them cool, dark, and dry under a bed or in a closet. Freeze-dried food always needs an oxygen absorber. A freeze dryer only makes sense when you are storing for many years and want to keep the most nutrients.
- Keep moisture, oxygen, and light out of dry staples.
- Mylar bag plus one oxygen absorber per bag for grains and beans.
- Drop sealed bags into food-grade 5-gallon buckets.
- Store cool, dark, and dry, and rotate oldest to front.
Do not forget water
Food is only half the plan. Store at least one gallon of water per person per day in food-grade containers, which covers drinking and basic cooking. For a two-week supply, that is 14 gallons per person. Water is heavier and bulkier than food, so plan the space early.
Store water in clean, food-grade containers, never in old milk jugs or containers that held chemicals. Keep it cool and dark, and rotate it on a schedule. Our free calculator below sizes both your food and water at once so you are not guessing.
- At least one gallon of water per person per day.
- That is 14 gallons per person for two weeks.
- Use clean, food-grade containers only.
- Store cool and dark, and rotate on a schedule.
Get your exact numbers in two minutes
The math above is per adult. Real households mix adults, teens, and kids, and different storage goals. Doing that by hand is where most plans stall.
Use our free Prepper Supply Calculator to skip the math. Enter your household and your target, from 3 days to 1 year, and it gives you the calories, the bulk-staple pounds, and the water to store. It turns a vague worry into a clear shopping list you can build a little at a time.
- Enter adults, children, and your day target.
- Get calories, staple pounds, and water in one screen.
- Build the list a few items per grocery trip.
Questions, answered straight
Plan about 730,000 calories per adult, or roughly 2,000 a day. The classic bulk-staple framework, from LDS and Provident Living and extension long-term storage guidance, puts it at about 300 to 400 lb of grains, 60 lb of legumes, 20 to 25 lb of fats, 60 lb of sugar, 15 lb of dry milk, and 8 lb of salt per adult. Treat these as ranges.
About 2,000 calories per adult per day is the standard planning floor, in line with common USDA Dietary Guidelines references. Active adults, teens, and people in cold weather need more, while young children need less. Store extra as a buffer if you can.
Scale the per-adult numbers to your household. Four adults need about 8,000 calories a day, or roughly 2.9 million calories for a year. Kids eat less, so count young children as a partial share. Add one gallon of water per person per day. A calculator makes the exact math easy.
For most families, start with two weeks, not a year. A two-week supply covers the great majority of storms, outages, and short job gaps, and it is cheap and easy to rotate. Build toward one month, then a year, only after the basics are in place. A year is a real project, not a first step.
