Calories Burned Calculator | Calculate Exercise Energy Expenditure

Meet Alex, a 29-year-old fitness enthusiast. He just finished a 45-minute jog and wonders: “How many calories did I actually burn? Can I eat that slice of pizza guilt-free?”

Many people exercise without knowing the true energy cost of their workouts. That’s where the Calories Burned Calculator comes in. It estimates the calories you burn during different exercises based on your weight, activity type, intensity, and duration.

What is this Calculator?

The Calories Burned Calculator is a tool that helps you measure energy expenditure during physical activity. Instead of guessing, it uses your personal details to give a realistic estimate of calories burned.

It takes into account:

• Your body weight (heavier individuals burn more calories for the same activity).
  
• The type of activity (running, cycling, swimming, yoga, etc.).
  
• Exercise intensity (light, moderate, vigorous).
  
• Duration of exercise (in minutes).
  

The result helps you:

• Plan your meals accurately.
  
• Track progress toward weight loss or fitness goals.
  
• Understand how different activities impact your total daily energy expenditure.
  

Why is This Important?

1. Weight Management – Know how many calories your body burns to maintain, lose, or gain weight.
   
2. Exercise Planning – Adjust workout duration and intensity based on calorie goals.
   
3. Nutrition Accuracy – Helps prevent overeating or underfueling after workouts.
   
4. Motivation – Seeing calories burned in real numbers encourages consistency.
   
5. Health Tracking – Supports heart health, metabolism, and fitness improvements.
   

Formula to Calculate Calories Burned

Calories burned are calculated using METs (Metabolic Equivalent of Task), a standard way to measure energy expenditure:

Calories Burned = Duration (minutes) × MET × 3.5 × Weight (kg) ÷ 200

Where:

• Duration = time spent exercising in minutes
  
• MET = intensity value assigned to the activity
  
• Weight = body weight in kilograms
  

Example:
Alex weighs 70 kg, runs for 45 minutes at moderate intensity (MET = 8):

Calories Burned = 45 × 8 × 3.5 × 70 ÷ 200

                 = 441 calories

This means Alex burned roughly 441 calories in his run.

How the Calculator Works – Step by Step

1. Enter your body weight – in kilograms.
   
2. Select your activity type – running, cycling, swimming, walking, yoga, etc.
   
3. Choose intensity level – light, moderate, or vigorous.
   
4. Enter exercise duration – in minutes.
   
5. Press calculate – the tool instantly shows calories burned.
   
6. Apply results – use this number to adjust meals or track total energy expenditure for the day.
