In the journey toward better health, knowing how many calories you burn during exercise is as crucial as counting what you consume. That’s where our Exercise Calorie Burn Calculator comes in — a smart, fast, and reliable tool that gives you accurate estimates of your energy expenditure based on your weight, activity level (MET), and duration of workout.
Whether you’re a beginner trying to lose weight, an athlete optimizing your performance, or a fitness enthusiast curious about your output, this tool empowers you with the insights you need to stay on track.
Exercise Calorie Burn Calculator
🧠 What Is the Exercise Calorie Burn Calculator?
The Exercise Calorie Burn Calculator is a web-based tool that calculates how many calories you burn during a physical activity based on three inputs:
- Your weight (in kg)
- MET value of the activity
- Duration (in minutes)
It uses a scientifically proven formula based on MET (Metabolic Equivalent of Task) to determine energy expenditure. MET values are established estimates of how much energy different activities use — for example, walking might be 3.5 METs, while running can range from 7 to 12 METs depending on speed.
🧮 How the Calculation Works
The formula used is:
Calories Burned = (MET × 3.5 × Weight in kg / 200) × Duration (in minutes)
This formula is backed by fitness science and widely accepted across academic and health institutions.
For example:
- Weight: 70 kg
- MET: 8 (e.g., vigorous cycling)
- Duration: 30 minutes
Calories Burned = (8 × 3.5 × 70 / 200) × 30 = 294 kcal
This calculation gives you a highly accurate estimate of how many calories you've used.
🛠️ How to Use the Calorie Burn Calculator
Using the calculator is simple and beginner-friendly. Here's how:
Step 1: Enter Your Weight (in kg)
Add your current body weight. This is crucial because calorie burn is directly related to how much mass you move during activity.
Step 2: Enter the MET Value
Input the MET value of the activity. You can find MET values for hundreds of activities online or through fitness databases. For example:
- Light walking: 3.0 METs
- Jogging: 7.0 METs
- Intense swimming: 10.0 METs
Step 3: Enter Duration (in minutes)
Put in how long you performed the activity. The longer you exercise, the more calories you'll burn.
Step 4: Click "Calculate"
The calculator will instantly show the number of calories burned in a visually clean and user-friendly display.
Step 5: Reset (Optional)
Click "Reset" to clear all fields and start fresh.
✅ Benefits of Using This Tool

🧪 Real-Life Example
Let's say Sarah is a 65 kg woman who goes for a 45-minute jog.
- MET value for jogging: 7
- Weight: 65 kg
- Duration: 45 minutes
Calories Burned = (7 × 3.5 × 65 / 200) × 45 = 358.31 kcal
Sarah burns approximately 358 kcal during her jog. She can now log this into her fitness app or diet tracker to stay on top of her goals.
⚖️ What Are MET Values and Where to Find Them?
MET (Metabolic Equivalent of Task) is a unit that estimates how much energy an activity uses compared to sitting quietly. 1 MET is the rate of energy expenditure at rest.
Here are some common MET values:
| Activity | MET Value |
|---|---|
| Sleeping | 0.9 |
| Sitting quietly | 1.0 |
| Walking (3 mph) | 3.5 |
| Cycling (moderate) | 6.0 |
| Running (6 mph) | 9.8 |
| Jump rope (fast) | 12.3 |
You can get comprehensive MET charts from fitness databases, government health websites, or sports medicine journals.
🧠 Tips to Use the Calculator Effectively
- Round your weight to the nearest 0.1 kg for better accuracy.
- Always choose the MET value that closely matches your intensity level.
- Break long workouts into segments if intensity changes.
- Use it to compare which exercises burn more calories.
- Combine it with your calorie intake tracking for better weight control.
📚 Frequently Asked Questions (FAQs)

10. What if I don’t know the MET value?
You can look it up based on the type and intensity of your activity.
11. Is it safe to rely only on this for weight loss?
Use it as a guide. Always consult health professionals for medical advice.
12. What is the formula used?
Calories = (MET × 3.5 × Weight in kg / 200) × Duration
