Our Exercise Calories Burned Calculator helps you estimate the calories you burn during gentle, low-impact activities like walking, cycling, yoga, and stretching. Whether you're new to fitness, recovering from injury, or simply prefer a softer approach to movement, this tool gives you a realistic estimate based on your body weight, activity duration, and the intensity of your session.
Using the widely accepted MET (Metabolic Equivalent of Task) method, the calculator applies activity-specific MET values to your personal data. You can choose from a range of common gentle activities, adjust the intensity level, and even include your age and gender for a more personalized estimate. The result includes a clear breakdown of the calculation, so you can see exactly how the number was derived.
This calculator is perfect for anyone tracking daily activity, planning a gentle fitness routine, or simply curious about the energy cost of their favorite low-impact exercises. It's also a great companion for those who want to balance calorie intake with gentle movement.

How to Use This Tool
Using the Exercise Calories Burned Calculator is straightforward. Start by selecting the activity that best matches your session from the dropdown list. Then choose the intensity level — light, moderate, or vigorous — based on how hard you feel you're working. For example, a leisurely walk in the park would be light, while a brisk walk that gets you slightly out of breath would be moderate.
Next, enter your body weight and the duration of your activity. You can switch between kilograms and pounds, and between minutes and hours, to suit your preference. The optional age and gender fields allow the calculator to apply a small adjustment to the MET value, making the estimate more personalized. Once you click Calculate, you'll see the estimated calories burned along with a breakdown of the calculation.
If you're in a hurry, use the quick-fill buttons to load a common weight and duration combination, then adjust as needed. The reset button clears all inputs and results so you can start fresh.
How It Works
This calculator uses the MET (Metabolic Equivalent of Task) method, which is a standard way to estimate energy expenditure during physical activities. One MET is the rate of energy expenditure while sitting at rest, roughly equivalent to consuming 1 kcal per kilogram of body weight per hour. When you exercise, your body burns more energy, and the MET value reflects how many times more energy you're using compared to rest.
The formula we use is:
Calories burned = MET × 3.5 × weight (kg) ÷ 200 × duration (minutes)
The constant 3.5 represents the oxygen consumption in milliliters per kilogram per minute at rest, and dividing by 200 converts the result into calories. This formula is widely used in fitness research and by health organizations. The MET values for each activity are based on the Compendium of Physical Activities, a comprehensive list of MET values for hundreds of activities, maintained by researchers at Arizona State University and the National Institutes of Health.
For example, walking at a moderate pace has a MET of about 3.5, while gentle yoga has a MET of about 2.5. If you weigh 70 kg and do moderate walking for 30 minutes, the calculation would be: 3.5 × 3.5 × 70 ÷ 200 × 30 = 128.6 calories. That's a reasonable estimate for a 30-minute walk.
Worked Examples
Example 1: Walking
Weight: 70 kg, Activity: Walking (moderate), Duration: 45 minutes.
MET = 3.5. Calories = 3.5 × 3.5 × 70 ÷ 200 × 45 = 192.9 kcal.
Example 2: Gentle Yoga
Weight: 60 kg, Activity: Yoga (gentle), Duration: 60 minutes.
MET = 2.5. Calories = 2.5 × 3.5 × 60 ÷ 200 × 60 = 157.5 kcal.
Example 3: Leisurely Cycling
Weight: 80 kg, Activity: Cycling (leisurely), Duration: 30 minutes.
MET = 4.0. Calories = 4.0 × 3.5 × 80 ÷ 200 × 30 = 168 kcal.
Tips & Best Practices
- Be honest about your intensity level. It's easy to overestimate how hard you're working, which can lead to an inflated calorie estimate.
- Use your current body weight, not your goal weight, for the most accurate result.
- If you're doing an activity that isn't listed, choose the closest match. For example, light gardening can be similar to moderate walking.
- Remember that this is an estimate. Individual metabolism, fitness level, and body composition all affect actual calorie burn.
- For weight management, focus on consistency and overall activity rather than obsessing over exact numbers.
Factors Affecting Accuracy
Several factors can influence how accurate the estimate is for you personally. Your metabolic rate, muscle mass, and even the temperature of your environment can change how many calories you burn. The MET values are averages from population studies, so your actual burn may be higher or lower. Additionally, the optional age and gender adjustment is a simple linear correction and may not capture all individual differences.
For the most precise measurement, you could use a heart rate monitor or a fitness tracker that accounts for your heart rate and other personal data. However, for most people, this calculator provides a useful ballpark figure that can help with planning and motivation.
Frequently Asked Questions
How many calories do I burn walking for 30 minutes?
For a 70 kg person walking at a moderate pace (MET 3.5) for 30 minutes, the estimate is about 128 calories. If you weigh more, you'll burn more; if you weigh less, you'll burn fewer.
Is yoga a good way to burn calories?
Gentle yoga burns fewer calories than more vigorous activities, but it still contributes to your daily energy expenditure. A 60-minute gentle yoga session for a 60 kg person burns about 157 calories. More dynamic styles like Vinyasa or power yoga can burn more.
Can I use this calculator for weight loss planning?
Yes, you can use the estimate to understand how much energy you're expending through gentle exercise. To lose weight, you generally need to create a calorie deficit, which means burning more calories than you consume. This calculator can help you track the exercise side of that equation.
Why is the MET value different for the same activity at different intensities?
MET values are designed to reflect the energy cost of an activity at a given intensity. Higher intensity means your body works harder, uses more oxygen, and burns more calories per minute. The Compendium of Physical Activities provides separate MET values for light, moderate, and vigorous versions of many activities.
Where can I learn more about MET values?
The Compendium of Physical Activities is a great resource. You can find it online at the Compendium website. It's maintained by researchers and is widely used in health and fitness research.
