How to Use the Food Storage Calculator
Use this calculator to estimate how much emergency food your household should store for disasters, power outages, or long-term emergencies. The calculator estimates food quantities based on household size, calorie needs, and how long you want your food supply to last.
Follow these steps:
1. Enter the Number of People
Start by entering the number of people in your household who will rely on the food storage supply.
Include:
- Adults
- Children
- Anyone living in the household full-time
Example:
If you are preparing food storage for two adults and two children, enter 4 people.
2. Select Your Storage Duration
Choose how long you want your emergency food supply to last.
Common preparedness timeframes include:
- 7–14 days – basic emergency kit
- 30 days – short-term disaster preparedness
- 3 months – recommended minimum preparedness level
- 6–12 months – advanced prepper storage
If you’re new to preparedness, starting with 30–90 days of food storage is a realistic goal.
3. Choose Daily Calorie Needs
Select the approximate number of calories each person needs per day.
Typical ranges include:
- 1800–2000 calories – light activity

- 2500–3000 calories – physically active individuals
During emergencies, calorie needs may increase due to physical work, stress, and colder temperatures.

Important Food Storage Tips
Keep these preparedness tips in mind when building your emergency pantry:
Store foods you actually eat.
Rotate supplies regularly to maintain freshness.
Focus on calorie-dense staples.
Foods like rice, beans, oats, and oil provide essential calories.
Build your supply gradually.
Most preparedness experts recommend starting with a 30-day food supply and expanding over time.
Don’t forget water storage.
A good rule is one gallon of water per person per day.
Example Food Storage Calculation
For example:
Household: 4 people
Duration: 3 months
Calories: 2000 per day
Estimated supplies may include:
- 120 lbs of rice
- 60 lbs of beans
- 45 lbs oats
- 30 cans of vegetables
- 10 gallons of cooking oil
This provides enough calories to support a family during an extended emergency.
