Calorie estimates come from the federal table published with the 2015–2020 Dietary Guidelines. The 2025–2030 Guidelines say needs vary by age, sex, height, weight and activity and do not give one number for everyone.
This is a planning sketch, not a diet. Medical conditions, age, and heavy work change needs.
- CDC: at least 3 days, and a 2-week supply if possible. https://www.cdc.gov/water-emergency/about/how-to-create-and-store-an-emergency-water-supply.html
- Red Cross: 3 days for evacuation, 2 weeks at home. https://www.redcross.org/get-help/how-to-prepare-for-emergencies/survival-kit-supplies.html
- CDC: Consider storing more water than this for pregnant women, people who are sick, pets, or if you live in a hot climate. Ready.gov: Children, nursing mothers and sick people may need more water. https://www.ready.gov/water
- ASPCA kit list: At least seven days' worth of bottled water for each person and pet (store in a cool, dry place and replace every two months). https://www.aspca.org/pet-care/general-pet-care/disaster-preparedness

Add height and weight for everyone above to carry your household into the planner.
The Wolf Den Pack Planner is Wolf Den Foods' own tool. It estimates calories with the 2023 National Academies Estimated Energy Requirement equations (Dietary Reference Intakes for Energy, 2023, https://doi.org/10.17226/26818) using each person's height and weight. This page uses the 2015–2020 Dietary Guidelines calorie table (reference-size people). Both are estimates and neither is a resting metabolic rate (BMR), so the totals can differ.
