30-Day Emergency Food Supply: Complete List
A 30-day emergency food supply for one adult works out to roughly 60,000 calories across 90 meals. The practical list centers on white rice, dried beans, rolled oats, pasta, canned proteins, vegetable oil, and powdered milk. Stored in sealed containers in a cool, dark location, most of these foods stay good for 5 to 25 years.
That baseline covers survival. What you actually build should account for the number of people in your household, any dietary restrictions, how you plan to cook without a stove, and whether you need shelf-stable vegetables for nutritional completeness. Each variable shifts the quantities meaningfully.
How many calories does a 30-day food supply need to cover?
The USDA Dietary Guidelines recommend 2,000 calories per day for the average sedentary adult, putting the 30-day target at 60,000 calories per person (USDA Dietary Guidelines for Americans 2020-2025). Active adults, teenagers, and people doing heavy physical work need 2,500 to 3,000 calories daily, so plan 75,000 to 90,000 calories for those household members. Children under 8 generally need 1,200 to 1,400 calories per day.
Most storage mistakes happen because people count cans or volume rather than calories. A number-10 can of freeze-dried strawberries looks substantial but delivers fewer than 300 calories total. A 10-pound bag of white rice, by contrast, provides about 16,400 calories and costs roughly $7. Calorie density is the right unit for planning.
A simple household formula: multiply each adult’s daily calorie target by 30, add children’s totals, then divide that grand total by the calorie density of each food you plan to store. The table below shows the math already done for a single adult at 2,000 calories per day.
What goes on a 30-day emergency food supply list?
Six categories cover most of the calories, protein, and cooking flexibility you need: grains, legumes, fats, canned proteins, dairy alternatives, and a small amount of preserved vegetables. Below is a complete 30-day list for one adult, with quantities, calories per pound, and expected shelf life in properly sealed storage:
| Food | Qty (1 adult, 30 days) | Cal/lb | Shelf life (sealed) |
|---|---|---|---|
| White rice | 10 lbs | 1,640 | 25+ years |
| Dried pinto or black beans | 10 lbs | 1,530 | 25+ years |
| Rolled oats | 5 lbs | 1,700 | 30 years |
| Pasta (spaghetti or penne) | 3 lbs | 1,570 | 25+ years |
| All-purpose flour | 3 lbs | 1,650 | 5-10 years |
| Vegetable oil or shortening | 2 lbs | 3,500 | 2-4 years |
| Powdered whole milk | 3 lbs | 1,630 | 20+ years |
| Sugar | 2 lbs | 1,760 | Indefinite |
| Honey | 1 lb | 1,380 | Indefinite |
| Canned tuna (5 oz) | 8 cans | varies | 3-5 years |
| Canned chicken (12.5 oz) | 4 cans | varies | 3-5 years |
| Freeze-dried mixed vegetables | 1 lb | 200-300 | 25+ years |
| Salt | 1 lb | 0 | Indefinite |
| Multivitamins | 30-count bottle | minimal | Per label |
The dry goods in this list total roughly 62,500 calories before adding canned proteins and vegetables, which contribute another 3,000 to 5,000 calories. The 5 to 12 percent buffer above the 60,000-calorie minimum accounts for cooking losses, variety, and the fact that calorie needs vary day to day.
Grocery cost for this list runs $90 to $140 per adult at standard supermarket prices as of mid-2026, depending on brand choice and whether you buy in bulk. A warehouse club cuts the grain and bean costs by 30 to 40 percent.
How much water should you store alongside your food?
FEMA recommends one gallon of water per person per day for drinking and basic sanitation, which puts the 30-day total at 30 gallons per person (FEMA Ready.gov). Cooking dried beans and rice from scratch uses an additional 1 to 2 cups per meal, so plan for 3 to 5 extra gallons per person per month on top of drinking water.
Thirty gallons weighs 250 pounds, which is a real storage challenge. Practical options include five stackable 7-gallon containers, one 55-gallon food-grade drum (stores water for four adults at roughly $80 to $120), or a combination of store-bought bottled water and stored tap water. A portable gravity filter rated at 0.1 micron or finer reduces how much pre-stored water you need by giving you the ability to treat additional sources on site.
How do you store a 30-day food supply so it actually lasts?
Grains, legumes, and pasta reach their 25-year shelf life only when four conditions are met: low oxygen, low moisture, stable cool temperature, and light exclusion. Standard paper bags and thin plastic packaging satisfy none of them.
The reliable storage method is Mylar bags with oxygen absorbers placed inside food-grade 5-gallon buckets with gamma-seal lids. A 5-gallon bucket holds roughly 30 to 33 pounds of rice or 25 pounds of beans. For each bucket, use one 2,000cc oxygen absorber (or two 1,000cc absorbers), heat-seal the Mylar bag with a clothes iron, then close the lid. Label every bucket with the food type, pack date, and expected expiration year.
For canned goods, storage between 50 and 70 degrees Fahrenheit is the standard target. A 10-degree temperature increase roughly halves effective shelf life, which makes a hot garage a poor location regardless of what the can label says. A climate-controlled interior room, a basement, or a stable interior closet works well.
Vegetable oil is the shortest-lived item on this list at 2 to 4 years. Keep it in rotation: buy, use, replace on a cycle. Coconut oil and ghee last closer to 2 years at room temperature and up to 5 years refrigerated; neither requires refrigeration until opened.
What do most 30-day emergency food lists overlook?
Four categories appear on almost no beginner list but matter significantly in practice.
Cooking fuel
A 30-day supply of dry goods is not usable if you cannot boil water consistently. Cooking dried beans from scratch requires a rolling boil for 60 to 90 minutes. A propane camp stove with two or three one-pound canisters gives you roughly 3 to 5 hours of total cooking time at high flame. For a full month of cooking, plan on one 1-lb canister per 2 to 3 days, or consider a rocket stove that burns small-diameter wood, which eliminates the fuel storage problem entirely.
Fat calories
The list above includes 2 pounds of vegetable oil. At 3,500 calories per pound, that is 7,000 calories total, or about 233 calories per day from fat. Fat keeps you satiated, carries fat-soluble vitamins A, D, E, and K, and makes plain rice and beans palatable across an extended period. Under-storing fat is one of the most consistent mistakes in beginner supply lists. If you can fit 3 pounds of oil instead of 2, do it.
Comfort and morale foods
Palate fatigue on a monotonous diet is a documented issue in extended-emergency situations. Coffee, tea, hot cocoa mix, or hard candy (indefinite shelf life when sealed) cost almost nothing and matter more than the calorie math suggests by week three. Add a small quantity of any shelf-stable food your household actually enjoys.
Special dietary needs
Infants require formula or breastmilk, not powdered cow’s milk. People managing diabetes need to account for the high glycemic load of white rice and flour. Anyone on daily prescription medication needs a parallel 30-day medication plan. These are not uncommon situations; address them in your household’s specific list before you buy anything else.
How do you scale a 30-day food supply for more than one person?
Multiply each line item by household size, then adjust upward for members with higher calorie needs. For a family of four with two adults and two school-age children, a conservative working estimate is 2.5 adult-equivalents. Multiply each single-adult quantity by 2.5.
Children ages 5 to 12 generally need about 60 percent of adult calories but closer to 80 percent of adult protein. Teenagers often need as many calories as adults, and sometimes more if they are active. When in doubt, store slightly more than the calculation suggests. Surplus long-term storage food is not wasted; it becomes your rotation stock and reduces future grocery spending.
One useful cross-check: verify that your total stored calories divided by 30 days divided by household adult-equivalents lands at or above 2,000. If it does not, add more rice and beans first since those deliver the highest calories per dollar and per cubic foot of storage space.
Frequently Asked Questions
How long does it actually take to build a 30-day food supply?
Most households can assemble a functional 30-day supply over 4 to 8 weeks by buying a few extra items each grocery trip. No single large purchase is necessary. Prioritize grains and legumes first (highest calorie density per dollar), then canned proteins and fats, then storage containers and oxygen absorbers. By week four of this approach, the core of the supply is usually in place.
Can you survive on just the foods on this list for a full month?
Yes, provided the list covers enough total calories, adequate protein (50 to 60 grams per day for adults), sufficient fat, and some micronutrients. The freeze-dried vegetables and multivitamins address the most likely deficiency gaps: vitamin C drops out of most canned foods within 18 months, and the dried grains and beans provide almost no vitamins A or D. A daily multivitamin covers these gaps reliably.
What is the least expensive way to build a 30-day food supply?
White rice and pinto beans bought in 25-pound bags from a warehouse club or restaurant supply store are the most cost-efficient calories available. As of mid-2026, a 25-pound bag of white rice costs $12 to $18 and a 25-pound bag of pinto beans costs $18 to $28. Together they cover 30-plus days of carbohydrate and protein calories for one adult for under $50, before adding any other food.
Do you need to rotate a sealed 30-day supply?
Foods sealed in Mylar bags with oxygen absorbers inside buckets do not need rotation for 10 to 25 years. Items that do need rotation on shorter cycles: canned goods (3 to 5 years), vegetable oil (2 to 4 years), and baking powder (1 to 2 years). A label with the pack date on every container plus an annual inventory check in January keeps the supply current without significant ongoing effort.
How do you plan meals around stored food when you have no power?
Match your recipes to your fuel source before you finalize the list. If your only cooking option is a propane camp stove with limited fuel, avoid foods that require long boiling times. Canned beans (already cooked, need only heating), rolled oats (5 minutes on low heat), and pasta (10 minutes) are efficient fuel users. Dried beans from scratch take 60 to 90 minutes of boiling and should be reserved for situations where fuel is not a constraint.
Building a 30-day emergency food supply is a straightforward inventory problem. Start with the calorie math for your household, fill the table above scaled to your household size, store everything in sealed containers with oxygen absorbers, and record your pack dates. Check the list once a year. The shelf-stable items require almost no attention after that.
