Tai chi is a gentle, low-impact practice that combines slow, flowing movements with deep breathing and mindfulness. While it may look effortless, a 25-minute session can still burn a meaningful number of calories — especially when you maintain proper posture and engage your core throughout. This calculator estimates your energy expenditure based on your body weight, the intensity of your practice, and your age.
Whether you're a beginner exploring the basics or an experienced practitioner moving through a vigorous routine, this tool gives you a realistic calorie estimate for your 25-minute session. Simply enter your details, choose your intensity level, and hit calculate to see your results — along with a breakdown of how the numbers are derived.

How to Use This Tool
Enter your body weight in kilograms or pounds, select the intensity level that matches your tai chi practice, and optionally provide your age for a slightly more personalized estimate. The calculator uses the standard metabolic equivalent (MET) values for tai chi to estimate calories burned over a 25-minute session. If you're unsure about intensity, choose "Moderate" as a safe default — it reflects a typical tai chi class with steady, flowing movements.
How It Works
The calculation is based on the widely used formula: Calories burned = MET × 3.5 × weight (kg) / 200 × duration (minutes). MET (Metabolic Equivalent of Task) represents how many times more energy an activity uses compared to resting. For tai chi, the Compendium of Physical Activities assigns MET values of approximately 1.5 for slow, gentle practice, 3.0 for moderate practice, and 4.0 for vigorous practice. These values are derived from research on energy expenditure during traditional Chinese exercises.
Your age is used as a minor adjustment factor, since basal metabolic rate tends to decline slightly with age. The adjustment is capped to keep estimates realistic. The result gives you both the total calories for the 25-minute session and a per-minute rate, which can help you compare different activities or plan your weekly energy expenditure.
Worked Examples
Example 1: A 70 kg person practicing moderate tai chi for 25 minutes.
Calories = 3.0 × 3.5 × 70 / 200 × 25 = 91.9 kcal (before age adjustment).
Example 2: A 60 kg person doing vigorous tai chi for 25 minutes.
Calories = 4.0 × 3.5 × 60 / 200 × 25 = 105 kcal.
Tips & Best Practices
- Maintain proper posture and engage your core to maximize the workout benefit.
- Focus on slow, controlled breathing — this enhances the mind-body connection and can slightly increase energy expenditure.
- If you're new to tai chi, start with light intensity and gradually progress to moderate or vigorous as your balance and stamina improve.
- Combine tai chi with other gentle activities like walking or yoga for a well-rounded routine. You might also explore our qigong calorie calculator for a similar practice.
Factors Affecting Accuracy
Individual calorie burn can vary due to muscle mass, fitness level, and how faithfully you perform the movements. The MET values are averages from research studies, so your actual burn may be higher or lower. This estimate is best used as a general guide for tracking activity, not as a precise medical measurement.
Frequently Asked Questions
Is tai chi a good workout for weight loss? Tai chi is primarily a low-impact exercise that improves balance, flexibility, and mental well-being. While it burns fewer calories than high-intensity workouts, it can contribute to a calorie deficit when combined with a healthy diet and other activities.
How does tai chi compare to walking? Moderate tai chi (MET 3.0) burns calories at a similar rate to brisk walking (MET ~3.5). A 25-minute session can be comparable to a short walk, making it an excellent option for those who prefer a gentler, meditative approach.
Can I use this calculator for other durations? The formula is linear, so you can estimate other durations by multiplying the per-minute result by your desired minutes. For example, a 50-minute session would be roughly double the 25-minute estimate.
