What This Calculator Estimates
Calorie burn during exercise depends on activity type, intensity, duration, and body weight, with heavier individuals generally burning more calories for the same activity due to the additional energy required to move more body mass. This calculator uses MET (Metabolic Equivalent of Task) values — standardized intensity ratings for different activities — combined with your weight and duration to estimate calories burned for a specific activity session.
How to Use This Calculator
- Enter weight and activity duration.
- Select the activity that best matches your workout.
- Click Estimate Burn to view the result.
- Review the calorie estimate as a planning figure.
- Update the inputs when workout conditions change.

Tips for a More Accurate Estimate
- Remember calorie burn estimates are averages — individual results vary based on fitness level and exact intensity.
- Use a consistent activity and duration to track relative trends over time rather than exact totals.
- Consider a heart rate monitor or fitness tracker for more personalized estimates.
- Factor in that afterburn effect from intense workouts isn't captured in basic MET calculations.
- Combine calorie burn estimates with your TDEE for a complete picture of daily energy balance.
Frequently Asked Questions
What is a MET value?
A MET (Metabolic Equivalent of Task) is a standardized measure of how intense an activity is compared to resting, with higher MET values indicating more calories burned per unit of time.
Why does body weight affect calories burned?
Heavier individuals generally burn more calories doing the same activity because moving more body mass requires more energy.
Are calorie burn estimates precise?
No, they're estimates based on average MET values and population data — actual burn varies based on individual fitness level and exact intensity.
Does this account for afterburn effect (EPOC)?
No, this estimates calories burned during the activity itself, not the afterburn effect from intense exercise.
How can I get a more accurate calorie burn estimate?
Wearable fitness trackers with heart rate monitoring can provide more personalized estimates than generic MET-based calculations.
