Hiking Calorie Calculator
Estimate calories burned hiking from body weight, backpack weight, distance, duration, elevation gain, and descent. Unlike a flat walking estimate, this calculator shows how much of the result comes from moving across the route and how much comes from climbing or descending.
Calculate hiking calories
Elevation awareEnter the route details you know. Use total ascent and total descent from your trail app or route profile, not only the difference between the start and finish elevations.
This is a planning estimate, not a medical or laboratory measurement. Weather, trail surface, altitude, fitness, stops, poles, and movement efficiency can change real energy use.

How to read this result
Use the output as a route-planning range and compare it with your own hiking log over several trips.
How this hiking calorie calculator works
The calculation separates the cost of covering horizontal distance from the extra cost of climbing and descending. Body weight and backpack weight are combined because both must move along the trail.
Add body and pack weight
A heavier hiker or backpack generally requires more energy over the same route. Pack weight stays visible so you can compare a light day hike with an overnight load.
Estimate horizontal travel
Distance provides the base route cost. Duration is used to show hourly burn and to flag unusually long sessions, but speed alone does not erase the work of moving the full route.
Add ascent and descent
Climbing has a larger energy cost than level travel, while descending still requires muscular work. Enter cumulative gain and loss for a more useful estimate than start-to-finish elevation difference.
Example hiking calorie estimates
These route patterns show which inputs change the result most. Calculate your actual route instead of treating the examples as fixed calorie claims.
Short hike with little climbing
A light backpack and modest elevation change keep most of the estimate in the horizontal-distance portion, similar to a demanding walk.
Moderate distance with major ascent
A route with 600–1,000 m of gain can shift a large share of the estimate toward climbing, even when the distance is not especially long.
Long route with a heavier pack
The pack raises the mass moved across every kilometer and every meter of ascent. Split multi-day trips into stages so rest and fueling assumptions stay realistic.
Accuracy, assumptions, and safer planning
No hiking calories burned calculator can reproduce an individual metabolic test or every trail condition. Use the number as a transparent estimate, not a food reward or performance guarantee.
Use cumulative elevation
A loop that starts and ends at the same altitude can still contain substantial climbing. Export total ascent and descent from a trustworthy route profile when possible.
Surface and weather still matter
Mud, snow, loose rock, altitude, heat, cold, and strong wind can change effort without changing the route statistics entered here.
Do not automatically eat back every calorie
For weight management, compare the estimate with maintenance calories, hunger, recovery, and several weeks of body-weight trend rather than one hike or one wearable reading.
Method notes and references
The tool uses a transparent distance-and-elevation model informed by established activity-energy concepts. The sources explain the underlying ideas; they do not make one calculator exact for every hiker.

Hiking calorie calculator FAQ
Direct answers about hiking calories, elevation gain, backpacks, watches, and route data.
How many calories does one hour of hiking burn?
It depends on body weight, backpack weight, distance covered, and elevation change. Enter the actual route because a steep one-hour climb can require much more energy than an hour on a gentle trail.
How much does elevation gain affect hiking calories?
Elevation gain can materially raise energy use because the hiker and pack must be lifted vertically. The calculator separates the estimated climbing contribution so you can compare the same distance with different ascent totals.
Does carrying a backpack burn more calories while hiking?
Usually yes. Backpack weight increases the total mass moved across the route and uphill. A heavier load also changes balance, fatigue, and pace, so treat large-pack estimates conservatively.
Why not use a normal walking calorie calculator?
A walking calculator is useful for flatter sessions. Hiking often includes cumulative ascent, descent, uneven terrain, and backpack weight, so a route-aware estimate better matches that search task.
Why does my watch show a different calorie number?
Wearables may use heart rate, GPS pace, personal fitness data, and proprietary models. This page uses route inputs instead. Compare both as estimates and look for consistency over repeated hikes.
