Food and water calculator
How much water and food your household needs for a set number of days. Start with 3 days, then build to 2 weeks.
Keep in mind
- Water: at least 1 gallon per person per day, for drinking plus cooking and washing. Plan more in hot weather and for kids, nursing mothers and sick people. Sources are in the water guide.
- Food: about 2,000 calories per adult per day is the standard planning number. Sources are in the pantry guide.
- The rice number is only there to show scale. A real pantry mixes foods you already eat.
- Build it up a little at a time. Never go into debt to prepare. See prep on a budget.
