Hiking Calorie Calculator
Estimate calories burned while hiking based on body weight, distance, duration, elevation gain, backpack weight, and terrain difficulty.
Results
This is a fitness estimate only. Actual calories burned can vary based on fitness level, hiking efficiency, trail surface, weather, altitude, rest stops, body composition, and tracking-device accuracy.
Use this Hiking Calorie Calculator to estimate calories burned during a hike using body weight, hiking distance, duration, elevation gain, backpack weight, and terrain difficulty. The calculator also estimates MET level, calories per hour, pace, and additional hiking metrics.
Important: Hiking calorie estimates are approximations. Actual energy expenditure varies significantly between individuals and environments.

What Is a Hiking Calorie Calculator?
A Hiking Calorie Calculator estimates how many calories may be burned during hiking activity. Hiking energy expenditure is influenced by more than just distance. Elevation gain, terrain difficulty, backpack load, and hiking speed can substantially change calorie requirements.
Compared with flat walking, hiking often requires additional energy because of climbing effort and uneven terrain.
Factors Affecting Hiking Calories Burned
| Factor | Effect on Calories |
|---|---|
| Body weight | Heavier individuals generally expend more energy |
| Distance | Longer hikes usually increase calories burned |
| Duration | More time generally increases expenditure |
| Elevation gain | Climbing typically increases energy demand |
| Backpack weight | Additional load may increase effort |
| Terrain difficulty | Uneven trails often require more energy |
Hiking Calorie Formula
Many hiking calorie tools estimate energy expenditure using MET values.
Calories Burned = MET × 3.5 × body weight (kg) × duration (minutes) ÷ 200
MET stands for Metabolic Equivalent of Task.
Higher MET values indicate more physically demanding activity.
Common Hiking MET Examples
| Activity | Approximate MET |
|---|---|
| Easy trail hiking | 5–6 |
| Moderate hiking | 6–7 |
| Steep hiking | 7–9 |
| Heavy backpack hiking | 8–10+ |
Worked Example
| Input | Example Value |
|---|---|
| Body weight | 180 lb |
| Distance | 5 miles |
| Duration | 2 hours 30 minutes |
| Elevation gain | 800 feet |
| Backpack | 10 lb |
| Terrain | Moderate trail |
| Output | Example Result |
|---|---|
| Calories burned | Estimated value |
| Calories/hour | Estimated value |
| MET estimate | 6.6 METs |
| Average pace | 2 mph |
MET Intensity Interpretation
| MET Range | Intensity |
|---|---|
| Below 3 | Light activity |
| 3–6 | Moderate activity |
| Above 6 | Vigorous activity |
Terrain Difficulty Examples
| Difficulty | Typical Description |
|---|---|
| Easy | Flat maintained path |
| Moderate | Mixed terrain with some climbing |
| Difficult | Steeper uneven terrain |
| Technical | Rocky or challenging conditions |

Frequently Asked Questions
How accurate is a hiking calorie calculator?
Results are estimates and may differ from actual calorie expenditure.
Does elevation affect calorie burn?
Yes. Climbing generally increases energy demand.
Does carrying a backpack increase calories burned?
Additional load often increases physical effort.
Why do MET values matter?
MET values estimate activity intensity and are commonly used in calorie calculations.
Can slower hiking burn more calories?
Steeper or difficult terrain can increase energy expenditure despite lower speed.
Disclaimer: This Hiking Calorie Calculator provides an estimated calorie expenditure only. Actual calories burned can vary substantially based on fitness level, hiking efficiency, altitude, trail conditions, weather, body composition, rest periods, terrain surface, and wearable tracking accuracy. Results should be used as approximations rather than exact measurements.
