Curious how many calories a 20-minute yoga session actually burns? This calculator gives you a realistic estimate based on your body weight, the style of yoga you practice, and your effort level. Whether you're flowing through a gentle Hatha class, holding poses in Vinyasa, or pushing through a hot power session, the numbers vary more than you might think.
Built for yogis of all levels, this tool uses the standard metabolic equivalent (MET) values for yoga to convert your effort into calories burned. Just enter your weight, pick your yoga style, and adjust the intensity slider to match how hard you worked. You'll get an instant estimate plus a breakdown of calories per minute and per pose, so you can compare sessions and plan your practice with confidence.
Use it to track your gentle movement goals, compare yoga to other low-impact activities, or simply satisfy your curiosity after class. No sign-up, no guesswork — just clear, science-based numbers.
🧘 Yoga Calories in 20 Minutes
How to Use This Tool
Enter your body weight in kilograms or pounds, select the yoga style that matches your session, and adjust the effort slider to reflect how hard you actually worked. The calculator uses the standard MET (metabolic equivalent) values for each yoga style, then multiplies by your weight and the 20-minute duration to estimate calories burned.
For the most accurate result, be honest about your intensity. A slow, mindful Hatha class with lots of resting poses is very different from a fast-paced Vinyasa flow or a hot power session. The effort slider lets you fine-tune between light, moderate, and vigorous effort, which can change the final number by up to 50%.
How It Works
The calculation follows the widely used formula for estimating energy expenditure:
Calories per minute = (MET × 3.5 × weight in kg) / 200
MET values represent how many times more energy an activity uses compared to sitting at rest. For yoga, the Compendium of Physical Activities assigns values ranging from about 2.0 for gentle stretching to 6.0 for vigorous power yoga. This calculator uses those standard values as a baseline, then adjusts them with your effort multiplier.
For example, a 70 kg person doing moderate Vinyasa (MET 4.0) burns about 4.0 × 3.5 × 70 / 200 = 4.9 calories per minute, or roughly 98 calories in 20 minutes. The same person doing gentle Hatha (MET 2.5) would burn about 61 calories, while a vigorous power session (MET 6.0) would push that to around 147 calories.
Worked Examples
Example 1: A 60 kg person does a gentle Hatha class at moderate effort. MET = 2.5. Calories per minute = 2.5 × 3.5 × 60 / 200 = 2.63. In 20 minutes: 52.5 calories.
Example 2: A 75 kg person does a vigorous power yoga session. MET = 6.0. Calories per minute = 6.0 × 3.5 × 75 / 200 = 7.88. In 20 minutes: 157.5 calories.
Example 3: A 55 kg person does restorative yoga at light effort. MET = 2.0 × 0.7 = 1.4. Calories per minute = 1.4 × 3.5 × 55 / 200 = 1.35. In 20 minutes: 27 calories.
Factors Affecting Accuracy
This estimate is based on averages and may not match your exact energy expenditure. Your age, gender, muscle mass, fitness level, and even room temperature can influence how many calories you burn. Hot yoga, for instance, may raise your heart rate and calorie burn, but the MET value already accounts for the vigorous nature of the practice.
Also, yoga is not just about calories. It improves flexibility, balance, and mental focus, and it can be an excellent complement to other forms of exercise. If you're using this number for weight management, remember that the total daily energy balance matters more than any single session.
Frequently Asked Questions
Why does yoga burn fewer calories than running? Yoga is a low-impact activity with lower MET values than running. Running at a moderate pace has a MET of about 8-10, while even vigorous yoga tops out around 6. That's why a 20-minute run typically burns more calories than a 20-minute yoga session.
Can I lose weight with yoga alone? Yes, but it's slower than with higher-intensity activities. A consistent practice combined with a balanced diet can support weight loss, especially if you progress to more vigorous styles like power or hot yoga.
How many calories does a 20-minute hot yoga class burn? For a 70 kg person, hot yoga at vigorous effort burns about 147 calories in 20 minutes. The heat increases sweat and heart rate, but the calorie burn is still driven by the intensity of the poses.
Is this calculator suitable for all yoga styles? It covers the most common styles: Hatha, Vinyasa, Power/Ashtanga, Hot, and Restorative. If you practice a different style, choose the closest match and adjust the effort slider.
