Squats are one of the most effective bodyweight exercises for building lower-body strength, but how many calories do they actually burn? The answer depends on your weight, the intensity of your squat routine, and how long you train. This calculator uses the standard MET (Metabolic Equivalent of Task) method to estimate the calories and fat burned during squat sessions, whether you're doing slow bodyweight squats, weighted squats, or high-intensity jump squats.
Simply enter your body weight, choose your squat intensity, and set your workout duration. The tool instantly shows your estimated calories burned, the equivalent fat loss in grams, and a breakdown of the calculation so you can see exactly how the numbers add up. It's perfect for fitness enthusiasts, beginners tracking their progress, and anyone curious about the energy cost of this classic exercise.
Use the quick-fill presets to see typical values, or adjust the inputs to match your own routine. The calculator is based on widely accepted MET values from the Compendium of Physical Activities, giving you a reliable estimate to support your fitness goals.

How to Use This Tool
Using the squat calorie calculator is straightforward. Start by entering your body weight in kilograms or pounds — the calculator automatically converts to kilograms for the formula. Next, select the intensity that best matches your squat routine:
- Light — slow, controlled bodyweight squats with minimal effort (MET 3.5)
- Moderate — standard bodyweight squats at a steady pace (MET 5.0)
- Vigorous — weighted squats, jump squats, or high-rep fast-paced sets (MET 8.0)
Finally, enter the duration of your session in minutes or hours. Click Calculate to see your estimated calories burned, fat loss in grams, and a full breakdown of the math. Use the Reset button to clear all fields, or tap a quick-fill preset to see typical values for common scenarios.
Formula Explained
The calculator uses the standard MET (Metabolic Equivalent of Task) method, which is widely accepted in exercise science. The formula is:
Calories per minute = MET × 3.5 × (weight in kg) / 200
This equation estimates the energy cost of an activity relative to your resting metabolic rate. One MET equals the energy you burn at rest, roughly 1 kcal per kg of body weight per hour. The 3.5 factor represents the average oxygen consumption (in ml/kg/min) at rest, and dividing by 200 converts the result to calories per minute.
For fat loss, we use the approximation that 1 gram of body fat contains about 7.7 kcal of energy. This is a common estimate used in fitness tracking, though actual fat loss depends on many factors including diet and overall energy balance.
Worked Examples
Example 1: A 70 kg person does moderate bodyweight squats for 15 minutes.
MET = 5.0, weight = 70 kg
Calories/min = 5.0 × 3.5 × 70 / 200 = 6.125 kcal/min
Total = 6.125 × 15 = 91.9 kcal
Fat loss ≈ 91.9 / 7.7 = 11.9 g
Example 2: A 155 lb (70.3 kg) person does vigorous jump squats for 20 minutes.
MET = 8.0, weight = 70.3 kg
Calories/min = 8.0 × 3.5 × 70.3 / 200 = 9.84 kcal/min
Total = 9.84 × 20 = 196.8 kcal
Fat loss ≈ 196.8 / 7.7 = 25.6 g
Tips & Best Practices
- Maintain proper form — keep your chest up, back straight, and knees tracking over your toes to prevent injury and maximize muscle engagement.
- Control the tempo — a slow, controlled descent (2-3 seconds) and explosive ascent can increase calorie burn and muscle activation.
- Add resistance gradually — holding dumbbells or a barbell increases intensity and calorie burn, but start light to master form.
- Combine with other exercises — squats are great for lower-body strength, but a balanced routine includes cardio and upper-body work. For more calorie estimates, try our bodyweight calorie calculator or lunge calorie calculator.
- Track your progress — use the calculator weekly to see how your calorie burn changes as you get stronger and increase intensity.
Factors Affecting Accuracy
The MET values used here are averages from the Compendium of Physical Activities, a research-based resource. However, individual calorie burn can vary by up to 20-30% due to:
- Body composition — muscle burns more calories than fat, even at rest.
- Age and gender — metabolic rate naturally declines with age, and men often have higher muscle mass.
- Fitness level — trained individuals may burn fewer calories for the same exercise due to improved efficiency.
- Form and speed — the exact pace and depth of your squats affect the actual MET.
Treat the result as an estimate, not a precise measurement. For weight loss, focus on overall calorie balance rather than exact per-exercise numbers.
Frequently Asked Questions
How many calories do 100 squats burn?
It depends on your weight and intensity. For a 70 kg person doing moderate squats, 100 squats might take about 5-7 minutes, burning roughly 30-45 calories. Vigorous jump squats could double that.
Can squats help me lose belly fat?
Squats strengthen and build muscle in your legs and glutes, but they don't specifically target belly fat. Fat loss occurs throughout the body when you maintain a calorie deficit. Combining squats with a healthy diet and cardio is the most effective approach.
How often should I do squats?
For beginners, 2-3 times per week with rest days in between is recommended to allow muscle recovery. As you progress, you can increase frequency or intensity.
What is the best squat intensity for fat loss?
Higher intensity (vigorous) burns more calories per minute, but you may not sustain it as long. A mix of moderate and vigorous sessions works well. Listen to your body and avoid overtraining.
