Jumping — whether it's jumping jacks, jump rope, or plyometric hops — is a surprisingly effective way to burn calories and improve cardiovascular fitness. This calculator estimates the fat and total calories you burn during any jumping session based on your body weight, the intensity of the activity, and the duration of your workout.
Using the standard metabolic equivalent (MET) values published in the Compendium of Physical Activities, the tool applies a widely accepted formula to convert your effort into kilocalories. You can choose from several jumping activities, adjust your weight in pounds or kilograms, and even factor in your resting metabolic rate to see the net calories burned above baseline.
Whether you're planning a HIIT routine, tracking your daily movement, or just curious about your jump rope workout, this calculator gives you a quick, evidence-based estimate. It's perfect for fitness enthusiasts, coaches, and anyone looking to understand the energy cost of playful, low-impact exercise.

How to Use This Tool
Enter your body weight (in kilograms or pounds), select the jumping activity that matches your workout, and specify how long you exercised. The calculator uses the metabolic equivalent (MET) values from the Compendium of Physical Activities to estimate the calories you burn. You can also check the option to subtract your resting metabolic burn, which gives you the net calories attributable to the exercise itself — useful if you're tracking your daily energy balance.
For quick entry, use the preset buttons to fill in common weights (70 kg or 155 lb) and durations (10 or 30 minutes). The result shows both total calories and estimated fat mass burned, along with a step-by-step breakdown of the calculation.
Formula Explained
The calculator applies the standard formula for estimating energy expenditure:
Calories burned = MET × weight (kg) × duration (hours)
MET (Metabolic Equivalent of Task) is a ratio of your working metabolic rate to your resting metabolic rate. For example, a MET of 8.0 means you're burning energy at 8 times your resting rate. The MET values used here are drawn from the Compendium of Physical Activities, a widely cited research resource. For fat mass, we use the common approximation that 1 gram of body fat yields about 7.7 kcal of energy, so fat burned (g) = net calories ÷ 7.7.
Worked Examples
Example 1: A 70 kg person does jumping jacks for 20 minutes. MET = 8.0, duration = 0.333 hours. Calories = 8.0 × 70 × 0.333 = 186.7 kcal. Fat burned ≈ 24.2 g.
Example 2: A 155 lb (70.3 kg) person jumps rope vigorously for 15 minutes. MET = 12.3, duration = 0.25 hours. Calories = 12.3 × 70.3 × 0.25 = 216.2 kcal. Fat burned ≈ 28.1 g.
Tips & Best Practices
- For accurate results, weigh yourself in the morning before eating, and use your actual body weight — not an ideal weight.
- If your session includes rest breaks, reduce the duration accordingly or choose a lower MET value.
- Use the net calorie option if you want to know the extra calories burned beyond what you'd burn sitting still.
- Combine jumping with strength training and a balanced diet for sustainable fat loss.
Factors Affecting Accuracy
MET values are averages based on population studies. Your actual calorie burn can vary with fitness level, age, gender, and how efficiently you move. Beginners often burn more calories than trained individuals at the same activity because they are less efficient. Also, the fat-burned estimate assumes that all net calories come from fat, which is only true during low-intensity, steady-state exercise. During high-intensity intervals, your body uses more carbohydrates. Use the results as a reasonable estimate, not a precise measurement.
Frequently Asked Questions
How many calories does 100 jumping jacks burn?
It depends on your weight and pace. A 70 kg person doing jumping jacks at a moderate pace (MET 8.0) burns about 9.3 kcal per minute. If 100 jumping jacks take about 2 minutes, that's roughly 18.6 kcal. For a more precise number, use the calculator with your actual duration.
Is jumping rope better than running for fat loss?
Both are excellent. Jumping rope at a vigorous pace has a MET of 12.3, which is higher than running at 6 mph (MET 9.8). However, running is easier to sustain for longer periods. The best choice is the one you enjoy and can do consistently.
Can I lose belly fat by jumping?
Spot reduction is a myth. Jumping burns overall body fat, and with a calorie deficit, you'll eventually lose fat from all areas, including your belly. Consistency and diet are key.
