Calorie Burn Calculator

Estimate how many calories you burn during workouts and everyday activities using MET values.

Frequently Asked Questions

How are calories burned calculated?

Calories burned are calculated using the formula: Calories = MET x Body Weight (kg) x Duration (hours). MET (Metabolic Equivalent of Task) represents the energy cost of an activity relative to rest. A MET of 1 equals resting metabolism, so an activity with a MET of 5 burns 5 times more calories than sitting still.

What are MET values?

MET (Metabolic Equivalent of Task) values are standardized measures of exercise intensity published by the Compendium of Physical Activities. One MET equals the energy expenditure at rest (approximately 3.5 mL of oxygen per kg per minute). Walking has a MET of about 3.5, jogging is 7, and running at 8 mph is 11.8.

How many calories does walking burn?

Walking burns approximately 80-140 calories per mile depending on your body weight and walking speed. A 150-pound person walking at 3 mph (moderate pace) burns about 100 calories per mile or 300 calories per hour. Walking faster or uphill increases calorie burn significantly. Walking has a MET value of 3.0-5.0 depending on speed.

How many calories does running burn per mile?

Running burns approximately 80-140 calories per mile, with the exact amount depending primarily on body weight rather than speed. A 155-pound person burns about 100 calories per mile regardless of pace. However, running faster burns more calories per hour because you cover more miles. A general estimate is about 0.63 calories per pound per mile.

Does weight affect calories burned?

Yes, body weight significantly affects calories burned during exercise. Heavier individuals burn more calories performing the same activity for the same duration because more energy is required to move a larger body. A 200-pound person burns roughly 50% more calories than a 130-pound person doing identical exercise at the same intensity and duration.

How accurate are calorie burn calculators?

Calorie burn calculators using MET values are generally accurate within 15-20% for most people. Factors that can affect accuracy include individual fitness level, body composition, exercise technique, and environmental conditions. Heart rate-based monitors tend to be more accurate for cardio activities. MET-based calculations provide reliable estimates for planning and tracking purposes.

What exercise burns the most calories?

High-intensity activities burn the most calories per hour. Running at 10 mph burns about 1,200 calories/hour (MET 14.5), jumping rope burns about 800-1,000 calories/hour (MET 12.3), and vigorous cycling burns about 700-900 calories/hour (MET 10-12). Swimming, rowing, and HIIT workouts are also among the highest calorie-burning exercises.

What is a Calorie Burn Calculator?

A calorie burn calculator estimates the number of calories you expend during physical activity. It uses the Metabolic Equivalent of Task (MET) system, which assigns a standardized value to each activity based on its energy expenditure relative to rest. By combining your body weight, activity type, and exercise duration, the calculator provides an accurate estimate of your total energy expenditure — invaluable for weight management, fitness tracking, or workout planning.

Calorie Burn Formula

The core formula is:

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

Where:

  • MET — Metabolic Equivalent of Task (dimensionless; 1 MET = resting metabolism)
  • Weight (kg) — body weight in kilograms
  • Duration (hours) — exercise time expressed in hours

Weight conversion: If your weight is in pounds, it is first converted to kilograms using:

Weight (kg) = Weight (lbs) × 0.453592

Example calculation: A 160 lb (72.6 kg) person running at 6 mph (MET 9.8) for 30 minutes:

Calories = 9.8 × 72.6 × 0.5 = 355 kcal

MET Values by Activity

MET values are standardized measures published by the Compendium of Physical Activities. One MET equals the energy expenditure at rest (approximately 3.5 mL of oxygen per kg per minute).

Calorie Burn Examples

30-Minute HIIT Workout

A 150 lb person doing 30 minutes of HIIT (MET 8.0) burns approximately 272 kcal. This is equivalent to about 1 pizza slice or almost 2 beers.

60-Minute Moderate Cycling

A 180 lb person cycling at a moderate pace (MET 8.0) for 60 minutes burns approximately 653 kcal. To burn the same amount walking, it would take about 112 minutes.

45-Minute Yoga Session

A 140 lb person practicing yoga (MET 3.0) for 45 minutes burns approximately 143 kcal. While lower intensity, yoga provides flexibility and stress-reduction benefits beyond calorie burn.

How to Use This Calculator

  1. Enter your body weight and select the unit (pounds or kilograms).
  2. Choose your activity from the categorized dropdown menu — covering running, cycling, swimming, gym workouts, sports, and daily activities.
  3. Enter the duration of your exercise in minutes.
  4. Click "Calculate Calories Burned" to see your results.

Your results include:

  • Calories burned in kilocalories (kcal)
  • Food equivalents — how many common food items your burn equals
  • Duration comparison — how long walking or running would take to burn the same amount

Tips for Accurate Results

  • MET values are population averages; your actual burn may vary based on fitness level, age, and exercise intensity.
  • Weigh yourself at a consistent time (e.g., morning before eating) for the most accurate input.
  • For mixed workouts, calculate each activity segment separately and add the totals.
  • Heart rate monitors tend to be more accurate for cardio activities; MET-based calculations are reliable for planning and tracking purposes.
  • Use the food equivalents as a helpful reference, but remember that nutrition quality matters as much as calorie count.
