This is a household planning estimate. Real needs vary by age, health, activity, diet, cooking losses, and available storage.
How we calculate
Adults count as full portions. Children count as 0.7 of an adult in this simple model. We multiply daily needs by the number of family members and days, then apply the selected buffer and supply mode.
