Calories Burned Calculator
Stop guessing your output. Whether you're lifting weights, running, or doing office work, our advanced calculator uses industry-standard MET Values and clinical Heart Rate Formulas to tell you exactly how much you've burned.
The Science of Calorie Burning
Whether your goal is weight loss, maintaining a healthy lifestyle, or athletic performance, understanding energy expenditure is crucial. Our Calories Burned Calculator goes beyond the standard web tools by offering two robust, scientifically-backed methods to track your progress: The MET system and the Heart Rate system.
By knowing your numbers, you can easily balance your caloric intake and optimize your workouts, ensuring every minute of your sweat equity counts.
Why our tool is different
- ✓Two Calculation Methods: Choose between Activity (MET) or precise Heart Rate formulas.
- ✓Food Equivalents: Instantly visualize your burn in real-world foods (e.g., Pizza, Apples).
- ✓Consistency Projections: See how a 3-day-a-week routine translates into monthly weight loss.
Did you know?
1 pound of body fat equals approximately 3,500 calories!
MET stands for Metabolic Equivalent of Task. It is a ratio that compares the working metabolic rate of a specific activity to your resting metabolic rate.
One MET is the energy you spend sitting quietly. Therefore, an activity with a MET value of 5 implies you are expending 5 times the energy you would sitting on the couch.
Calories = Duration (in mins) × (MET × 3.5 × Weight in kg) / 200
If you use an Apple Watch, Garmin, or WHOOP strap, you know your average heart rate during a workout. Because heart rate directly correlates with oxygen consumption (VO2), this method provides a highly customized calorie output specific to your cardiovascular effort.
We use the standard Keytel et al. (2005) formulas for calculating energy expenditure from heart rate.
Female: [(-20.4022 + (0.4472 × HR) - (0.1263 × W) + (0.074 × Age)) / 4.184] × Time
Are You Actually in a Calorie Deficit?
Burning calories during workouts is only part of fat loss. To lose body fat consistently, you must maintain a calorie deficit — meaning you burn more calories than you consume. Use our Calorie Deficit Calculator to see how your daily intake and activity levels work together.
