Formula
Total calories = (Adults × 2200 + Kids × 1400) × days
Water (L) = (Adults + Kids) × daily liters × days
Example: 2 adults, 2 kids, 14 days → 2×2200 + 2×1400 = 7200 cal/day → 100.8k calories total, 168 L water.
Tip: Add 10% buffer for unexpected guests or extended outages.
Full Description
Extended quarantines or emergencies require thoughtful pantry planning. This calculator estimates daily caloric needs, protein intake, water storage, and staple categories so your household stays nourished. Customize for different diets and use the pantry breakdown to balance grains, proteins, vegetables, and snacks.
Maintain a rotation system—consume older items first and restock to keep inventory fresh. Pair this plan with vitamin-rich items (canned tomatoes, frozen berries) and consider special needs such as baby food or medications.
Frequently Asked Questions
