Calorie calculator

Estimate how many calories you burn per day on trail, then use it as your planner target.

Estimated daily burn

3,350 kcal

Most backpackers pack 2,500–4,500 kcal/day; it's normal to pack less than you burn on short trips.

Estimate only — actual burn depends on terrain, temperature, fitness, and metabolism. Not medical advice.
