Climbing — whether on a stair climber, a rock wall, or a steep hiking trail — is one of the most effective low-impact ways to torch calories while building lower-body strength. This calculator estimates how many calories you burn per hour of climbing based on your body weight, the intensity of your effort, and the type of climbing you're doing.
Using the standard MET (Metabolic Equivalent of Task) values from the Compendium of Physical Activities, the tool applies a simple formula: calories per hour = MET × weight (kg) × 1.0. You can choose from several climbing activities — from gentle stair stepping to vigorous rock climbing — and adjust your weight in either pounds or kilograms. The result includes a clear breakdown so you can see exactly how the number is calculated.
Whether you're planning a workout, tracking your daily energy expenditure, or just curious about your favorite climbing activity, this calculator gives you a quick, reliable estimate. It's perfect for fitness enthusiasts, hikers, and anyone exploring gentle yet effective exercise options.

How to Use This Tool
Enter your body weight (in kilograms or pounds), select the climbing activity that best matches your session, and set the duration in minutes. The calculator uses the MET value for that activity, adjusted by the intensity level you choose (light, moderate, or vigorous). Press Calculate to see your estimated calorie burn for the entire session, plus a per-hour figure and a breakdown of the inputs used.
The intensity presets let you fine-tune the estimate: choose Light if you're taking it easy, Moderate for a typical workout, or Vigorous if you're pushing hard. The calculator multiplies the base MET value by 0.8, 1.0, or 1.2 respectively. This gives you a more personalized estimate than a one-size-fits-all number.
Formula Explained
The calculation follows the standard metabolic equivalent (MET) method used by exercise scientists. One MET is the energy cost of sitting quietly, roughly 1 kcal per kilogram of body weight per hour. For any activity, the energy expenditure is:
Calories per hour = MET × weight (kg)
For a session of d minutes, multiply by d/60.
The MET values used here come from the Compendium of Physical Activities, a widely cited reference for physical activity energy costs. For example, stair-treadmill ergometer (vigorous) has a MET of 9.0, while moderate rock climbing is 5.8. These values represent the energy cost relative to resting metabolism.
Worked Examples
Example 1: A 70 kg person does vigorous stair-treadmill climbing for 45 minutes. MET = 9.0. Calories per hour = 9.0 × 70 = 630 kcal. For 45 minutes: 630 × (45/60) = 472.5 kcal.
Example 2: A 150 lb person (68.0 kg) does moderate rock climbing for 1 hour. MET = 5.8. Calories per hour = 5.8 × 68.0 = 394.4 kcal. For 60 minutes: 394.4 kcal.
Example 3: A 60 kg person does light stair stepping (MET 5.0 × 0.8 = 4.0) for 30 minutes. Calories per hour = 4.0 × 60 = 240 kcal. For 30 minutes: 240 × 0.5 = 120 kcal.
Tips & Best Practices
- Use your current body weight for the most accurate estimate. If you're tracking weight loss, update the value regularly.
- Be honest about intensity. Most people overestimate how hard they're working. If you're not sure, choose moderate.
- For rock climbing, the MET values assume continuous climbing. If you spend a lot of time resting between attempts, your actual burn will be lower.
- Combine this estimate with a heart-rate monitor for a more personalized number, especially if you have a high fitness level.
Factors Affecting Accuracy
The MET method provides a good population average, but individual calorie burn can vary by 20–30% due to factors like age, gender, muscle mass, and fitness level. Heavier people burn more calories because moving a larger body requires more energy. Similarly, people with more muscle mass tend to burn more at the same intensity. The intensity adjustment helps, but it's still an estimate.
For the most precise measurement, consider using a wearable device that tracks heart rate and movement. However, for planning workouts or estimating daily energy expenditure, this calculator is a reliable and convenient tool.
Frequently Asked Questions
How many calories do I burn climbing stairs for 30 minutes?
For a 70 kg person at moderate intensity (MET 5.0), you'd burn about 5.0 × 70 × 0.5 = 175 kcal. At vigorous intensity (MET 9.0), it would be about 315 kcal.
Is rock climbing a good workout for weight loss?
Yes. Rock climbing engages your entire body, builds strength, and can burn 400–600 kcal per hour depending on intensity and body weight. It's also low-impact, making it gentle on joints.
Why does the calculator ask for weight in kg or lb?
The formula uses kilograms. If you enter pounds, the calculator converts to kg automatically (1 lb = 0.4536 kg).
Can I use this for hiking uphill?
Yes, the "Climbing Hills (no load)" option (MET 6.0) is a good approximation for hiking uphill without a backpack. If you carry a heavy pack, add 1–2 METs.
