The calculator picks a base maintenance-style calorie rate for each adult from your activity tier, then multiplies by one plus the buffer fraction to cover imperfect portions or an extra hungry night. That per-person-day value is multiplied by the number of campers and the number of days to produce total trip energy. The optional weight line assumes about 125 dietary kilocalories per ounce of realistic mixed trail food—adjust mentally if your menu is mostly oil, cheese, or fresh produce.
kcal/person/day = base_kcal × (1 + buffer% / 100)total_kcal = kcal/person/day × people × daysfood_lb ≈ total_kcal ÷ 125 ÷ 16The 125 kcal/oz heuristic is a mid-pack average for bars, dinners, nut mixes, and chocolate—not a lab measurement of your exact meals.
