How to use this calculator
Enter your body weight, the total hiking distance, and elevation gain for the trail. Add pack weight if you are carrying a daypack or backpack. Select the terrain type that best matches your trail conditions.
The calculator estimates total calories burned, calories per mile, and calories per hour. It also shows equivalent food items so you can plan your trail snacks and meals accordingly.
What affects hiking calorie burn
Body weight is the single biggest factor. Heavier hikers burn more calories because it takes more energy to move more mass. Elevation gain is the second most important factor because climbing against gravity is extremely energy intensive.
Terrain difficulty matters because uneven, rocky, or snowy surfaces force your muscles to work harder for stability. Pack weight adds load to every step you take. Even a 15 pound daypack makes a noticeable difference over several miles.
Frequently asked questions
How many calories does hiking burn?
Hiking burns about 80 to 100 calories per mile for a 150 pound person on flat terrain. Steep trails can burn 150 to 250+ calories per mile. Your actual burn depends on body weight, pack weight, elevation gain, and terrain difficulty.
Does elevation gain matter?
Yes, significantly. Climbing adds roughly 48 extra calories per 500 feet of gain for a 150 pound person. A hike with 2,000 feet of gain burns substantially more than the same distance on flat ground.
How does pack weight affect burn?
A 20 pound pack on a 150 pound person adds about 10 to 15 percent more calorie burn. The effect compounds with elevation and rough terrain, making backpacking much more demanding than day hiking.
Hiking vs walking calories?
Hiking typically burns 30 to 60 percent more calories than walking the same distance on pavement. The difference comes from uneven terrain, elevation changes, and engaging more stabilizer muscles.
