Calories Burned Calculator

Estimate calories burned during physical activities based on your weight, duration, and activity type using metabolic equivalent (MET) values.

This helps fine-tune the calculation for your personal effort level.

About the Calories Burned Calculator

The Calories Burned Calculator estimates the energy expenditure from various physical activities based on your weight, the activity type, intensity level, and duration. This calculator uses the Metabolic Equivalent of Task (MET) values, which represent the energy cost of physical activities as a multiple of resting metabolic rate.

Understanding METs (Metabolic Equivalent of Task):

A MET is a measure of energy expenditure, with 1 MET representing the energy expended while sitting quietly at rest:

  • 1 MET = 1 kcal/kg/hour = the energy cost of sitting quietly
  • Light Activity: 1.5 to 3 METs (e.g., slow walking, light housework)
  • Moderate Activity: 3 to 6 METs (e.g., brisk walking, cycling at a moderate pace)
  • Vigorous Activity: 6+ METs (e.g., running, swimming laps, heavy lifting)

Benefits of Tracking Calories Burned:

  • Weight Management: Understanding energy expenditure helps create a balanced approach to calorie intake vs. output.
  • Fitness Goal Setting: Tracking calories burned can help set realistic fitness goals and track progress.
  • Exercise Planning: Knowledge of calorie expenditure can help optimize workout routines for specific fitness objectives.
  • Motivation: Seeing the calories burned from activities can provide motivation to maintain an active lifestyle.
  • Health Awareness: Regular physical activity has numerous health benefits beyond calorie burning, including improved cardiovascular health, better mood, and increased strength.

How the Calculation Works:

The formula used to calculate calories burned is:

Calories Burned = MET × Weight (kg) × Duration (hours)

Where:

  • MET is the metabolic equivalent value for the activity
  • Weight is your body weight in kilograms
  • Duration is how long you performed the activity in hours

Activity Intensity Levels:

IntensityDescriptionMET AdjustmentSigns During Exercise
LightActivity that doesn't cause noticeable changes in breathing rateLower MET valueCan easily talk and sing; minimal sweating
ModerateActivity that makes you breathe somewhat harder than normalStandard MET valueCan talk but not sing; light sweating
VigorousActivity that makes you breathe hard and fastHigher MET valueCan only say a few words without pausing; heavy sweating

Factors Affecting Calorie Expenditure:

  • Body Composition: People with more muscle mass tend to burn more calories, even at rest.
  • Age: Metabolic rate generally decreases with age, affecting calorie expenditure.
  • Fitness Level: More fit individuals may burn fewer calories doing the same activity as they become more efficient.
  • Environmental Conditions: Temperature, humidity, and altitude can all affect how many calories you burn.
  • Genetics: Some people naturally burn calories at different rates due to genetic factors.

Tips for Increasing Daily Calorie Burn:

  • Incorporate High-Intensity Intervals: Short bursts of intense activity can significantly increase calorie burn and metabolic rate.
  • Add Strength Training: Building muscle increases your resting metabolic rate, helping you burn more calories even when not exercising.
  • Stay Active Throughout the Day: Take walking breaks, use stairs, or do quick exercises during otherwise sedentary periods.
  • Try New Activities: Your body adapts to repetitive movements, so varying your workouts can help maximize calorie burn.
  • Focus on Duration and Intensity: Either exercise longer or more intensely to increase overall calorie expenditure.
  • Stay Hydrated: Proper hydration helps your body function efficiently during exercise.
