Push-ups are a classic bodyweight exercise that builds upper-body strength, but they also burn calories and contribute to fat loss. This calculator estimates the fat you burn during a push-up session based on your body weight, exercise duration, and intensity level. It uses the Metabolic Equivalent of Task (MET) values from the Compendium of Physical Activities to provide a realistic estimate.
Whether you're doing a quick morning set, a timed challenge, or a full workout, this tool helps you track your effort. Simply enter your weight, choose your intensity, and set the duration. You'll get total calories burned, estimated fat grams, and a breakdown of the calculation. Perfect for fitness enthusiasts, beginners, and anyone curious about the energy cost of bodyweight training.

How to Use This Tool
Enter your body weight (in kilograms or pounds) and the total time you spent doing push-ups. Choose the intensity that best matches your effort: Light for slow, controlled reps with long rests; Moderate for a steady, continuous pace; Vigorous for fast, explosive push-ups or high-rep sets with minimal rest. The calculator then estimates the calories burned and the equivalent fat mass, assuming that 1 gram of body fat provides about 7.7 kcal of energy.
For the most accurate result, use your actual body weight and be honest about the intensity. If you're doing intervals (e.g., 30 seconds of push-ups, 30 seconds rest), choose the intensity that reflects the working effort, not the average over the whole session.
How It Works
The calculation uses the Metabolic Equivalent of Task (MET) values from the Compendium of Physical Activities. Push-ups are classified under calisthenics, with MET values ranging from about 3.5 for light effort to 8.0 for vigorous effort. The formula is:
Calories per minute = MET × 3.5 × (weight in kg) / 200
This is the standard equation used in exercise physiology to estimate energy expenditure. It assumes a resting metabolic rate of 3.5 ml of oxygen per kilogram per minute, and that 1 liter of oxygen consumed corresponds to roughly 5 kcal. The result is then multiplied by the duration in hours to get total calories.
To convert calories to fat grams, we divide by 7.7 kcal per gram of adipose tissue. This is a common approximation because body fat is not pure fat—it contains water and protein. The actual fat loss from a single session is usually much smaller than the estimate, but the number helps you understand the energy cost of your workout.
Worked Examples
Example 1: A 70 kg person does moderate push-ups for 10 minutes. MET = 5.0. Calories per minute = 5.0 × 3.5 × 70 / 200 = 6.125 kcal/min. Total = 6.125 × 10 = 61.25 kcal. Fat = 61.25 / 7.7 ≈ 7.95 g.
Example 2: A 155 lb person (about 70.3 kg) does vigorous push-ups for 15 minutes. MET = 8.0. Calories per minute = 8.0 × 3.5 × 70.3 / 200 = 9.84 kcal/min. Total = 9.84 × 15 = 147.6 kcal. Fat = 147.6 / 7.7 ≈ 19.2 g.
These examples show how intensity and duration directly affect the outcome. Doubling the MET value roughly doubles the calories burned, and increasing duration has a linear effect.
Tips & Best Practices
- Track your actual workout time—include only the time you're actively doing push-ups, not the rest between sets.
- Use a consistent intensity—if you're doing a mix of slow and fast reps, pick the intensity that matches the majority of your effort.
- Combine with a balanced diet—fat loss is primarily driven by a calorie deficit, not just exercise. Use this calculator to see how push-ups contribute to that deficit.
- Progress gradually—as you get stronger, you may naturally increase intensity, which will raise your calorie burn.
Factors Affecting Accuracy
The MET values are averages based on population studies. Your actual calorie burn depends on your age, gender, muscle mass, fitness level, and even your form. For example, a person with more muscle mass burns more calories at the same intensity because muscle tissue is metabolically active. Also, the MET values assume a steady-state effort; if you're doing very short bursts with long rests, the average intensity is lower than the peak.
This calculator is an estimate, not a medical measurement. For precise energy expenditure, you would need indirect calorimetry in a lab. However, for most people, the MET-based estimate is within 10-20% of the actual value, which is sufficient for tracking trends over time.
Frequently Asked Questions
How many push-ups do I need to do to burn 100 calories? That depends on your weight and intensity. A 70 kg person doing moderate push-ups burns about 6 kcal per minute, so 100 kcal would take about 16-17 minutes of continuous push-ups. At vigorous intensity, it would take about 10 minutes.
Does this calculator work for other bodyweight exercises? The MET values are specific to push-ups, but you can use similar calculators for other calisthenics. For example, our jumping jack calculator uses the same MET-based approach.
Why is the fat gram number so small? Because a single workout burns relatively few calories compared to the total daily energy expenditure. For example, 100 kcal is only about 13 grams of fat. That's why consistency and overall calorie balance matter more than any single session.
Can I use this for a push-up challenge? Yes, just enter the total time you spend doing push-ups each day. Over a week, you can sum the daily estimates to see your weekly calorie burn from push-ups alone.
