Calories Burned Calculator
Select an activity, enter your weight and duration to estimate how many calories you burned during exercise.
Estimate only Estimate only. Actual calories burned varies with intensity, fitness level and individual metabolism.
Calories Burned Calculator
Estimate calories burned by activity
Calories burned = MET × weight(kg) × duration(hours). MET values vary by activity intensity.
⚠️ Double-check important results. This is an educational estimate, not professional advice — and where it uses a rate, bracket or fee, those change over time. Verify anything you'll rely on, especially in legal, financial, tax or medical matters, and read our full disclaimer. Think a result is wrong? Tell us so we can fix it.
How Calories Burned Are Estimated
Calories burned are estimated using MET (Metabolic Equivalent of Task) values:
Calories = MET × weight(kg) × duration(hours)
One MET is the energy cost of sitting quietly (~1 kcal/kg/hour). Activities with higher MET values burn more calories: - Walking 3.5 mph: 3.5 MET - Running 6 mph: 9.8 MET (approx) - Cycling 12–14 mph: 8.0 MET - Swimming moderate: 6.0 MET - Weight lifting moderate: 3.5–4.0 MET
**Note**: These are estimates. Actual burn varies with intensity, body composition, fitness level and environmental conditions.
- MET × weight × duration
- Higher MET = more calories per hour
- Estimate — individual results vary
- Duration in minutes converted to hours
Worked Example
Example: 70 kg person running at 5 mph (7.0 MET) for 30 minutes.
- Duration = 30 min = 0.5 hours - Calories = 7.0 × 70 × 0.5 = 245 kcal - Per hour = 245 × 2 = 490 kcal/hr

Does this account for afterburn (EPOC)?
No. This estimates calories burned during the activity only. High-intensity exercise can increase post-exercise calorie burn (EPOC), which isn't included here.
Why does weight matter?
Heavier bodies require more energy to move the same distance, so a heavier person burns more calories doing the same activity for the same time.
