Calories Burned Calculator
Calculate calories burned during exercise using MET values. Supports 30+ activities from walking to swimming with adjustable duration and weight.
Select an activity, enter your weight and duration.
How Does the Formula Work?
The calories burned calculator uses the MET (Metabolic Equivalent of Task) system to estimate energy expenditure during physical activity. MET values from the Compendium of Physical Activities; a widely used research database; quantify the intensity of each activity relative to sitting quietly. Combined with your body weight and exercise duration, MET values provide a reliable estimate of total calorie burn.
MET = Metabolic Equivalent of Task
1 MET ≈ 1 kcal/kg/hour (resting energy)
Examples (70 kg person, 30 minutes):
Walking (3.8 MET): 3.8 × 70 × 0.5 = 133 kcal
Jogging (7.5 MET): 7.5 × 70 × 0.5 = 262.5 kcal
Running 10km/h (9.3 MET): 9.3 × 70 × 0.5 = 325.5 kcal
Swimming laps (8.0 MET): 8.0 × 70 × 0.5 = 280 kcal
Jump rope (11.0 MET): 11.0 × 70 × 0.5 = 385 kcal
Understanding MET Values
MET tells you how many times more energy an activity uses than sitting quietly, which is 1.0 MET. The CDC treats an activity as moderate when it costs 3 to 5.9 METs and as vigorous from 6 METs up. On that scale, walking at 5 km/h (3.8 MET) is moderate, jogging (7.5 MET) and jump rope (11.0 MET) are vigorous, and Hatha yoga (2.3 MET) sits below the moderate band. This calculator includes 38 activities across 9 categories with MET values from the Compendium of Physical Activities.
Using Calorie Burn for Weight Management
Combining this calculator with a BMR/TDEE calculator gives a fuller picture of your daily energy balance: body weight falls when you burn more energy than you take in. The food equivalents make that trade concrete. A 70 kg person jogging (7.5 MET) burns 8.75 kcal a minute, so the 235 kcal of a 44 g milk chocolate bar take about 27 minutes.
Activity Categories
The calculator organizes 38 activities into 9 categories: walking (4 activities from slow to hiking), running (4 from jogging to sprinting), cycling (5 including stationary bike), swimming (3 intensity levels), gym/strength (4 including HIIT and CrossFit), sports (6 popular sports), flexibility (4 from stretching to power yoga), dance/cardio (3 including jump rope), and other (5 including rowing, elliptical, and household chores). Each activity shows its MET value so you can compare intensities at a glance.
Methodology and Sources
MET values come from the Compendium of Physical Activities (Ainsworth et al., 2024), the reference used by the American College of Sports Medicine. The Compendium lists multiple MET values for the same activity depending on pace and effort, so the labels here represent common scenarios rather than a single fixed value. For a more detailed breakdown by swimming stroke or cycling speed, use our dedicated swimming and cycling calculators. Individual calorie burn can differ from these estimates due to fitness level, technique, terrain, and environment. The intensity bands are the CDC's, and the food portions come from USDA FoodData Central.
Tips & Recommendations
From walking to HIIT, organized in 9 categories with MET values from the Compendium of Physical Activities research database.
Calories scale linearly with body weight. A heavier person burns proportionally more calories doing the same activity for the same duration.
See your calorie burn in bananas, chocolate bars, and pizza slices, with portion sizes from USDA FoodData Central.
Try different activities to see which burns more. Jump rope (MET 11) burns over 4× more than walking (MET 2.3) per minute.
Frequently Asked Questions
How are calories calculated?
Using the MET formula: Calories = MET × weight(kg) × duration(hours). MET (Metabolic Equivalent of Task) values come from the Compendium of Physical Activities, a research database of exercise intensities.
What is MET?
MET stands for Metabolic Equivalent of Task. 1 MET equals the energy cost of sitting quietly (approximately 1 kcal/kg/hour). An activity with MET 7 burns 7 times more energy than sitting.
How accurate is this calculator?
MET-based calculations provide good estimates for average-intensity exercise. Actual calorie burn varies based on fitness level, body composition, exercise intensity, temperature, and individual metabolism.
Why does weight matter?
Heavier people burn more calories doing the same activity because more energy is needed to move more mass. The relationship is linear: a 90 kg person burns 90 ÷ 70 ≈ 1.286 times as much as a 70 kg person, about 28.6% more.
What are the food equivalents?
The result is restated in three foods, using USDA FoodData Central portions: a medium banana (118 g, 105 kcal), a 44 g milk chocolate bar (235 kcal) and a 107 g slice of cheese pizza (285 kcal). Real foods vary by brand and recipe.
