Stockpile Calculator

Build your exact household and we'll calculate how much water, food and supplies you really need — using FEMA, American Red Cross, USDA and CDC guidelines. Every number traces back to a real source (listed at the bottom).

Who are you preparing for?

Needs vary a lot by age, sex and size — add each person and pet so the numbers fit your household, not an average.

Sources & assumptions

  • Water — 1 gallon/person/day (½ drinking, ½ sanitation), doubled in extreme heat or for pregnancy/illness. Source: FEMA Ready.gov & American Red Cross.
  • Calories by age & sex from the USDA Dietary Guidelines for Americans 2020–2025 estimated energy needs, adjusted by activity; +400 cal/day when pregnant or nursing.
  • Food weight is calculated from those calories using USDA FoodData Central calorie densities (rice ≈1,650, dry beans ≈1,540, oats ≈1,690, canned meat ≈700, oil ≈4,000 cal/lb).
  • Medications — 7-day minimum, 30-day ideal supply of prescriptions. Source: CDC & Ready.gov.
  • Pets — roughly 1 oz of water per lb of body weight per day (AVMA); food per package feeding guidelines.

These are planning estimates for general preparedness, not medical or dietary advice. For specific health conditions, infants, or medications, follow your doctor's and the product's guidance.
