Calories Burned Calculator
How many calories you burn walking, running, cycling, lifting and 30+ other activities — based on published MET values.
What Determines Calories Burned?
The number of calories you burn depends on more than the exercise itself. Your body and the way you perform an activity both affect the final result. Understanding these factors makes it easier to interpret your calorie estimate.
- Body Weight: Heavier bodies usually burn more calories.
- Exercise Intensity: Harder activities require more energy.
- Workout Duration: Longer sessions increase total calorie burn.
- Activity Type: Different exercises have different energy demands.
- Fitness Level: Body efficiency changes calorie expenditure over time.
How to Calculate Calories Burned
What Is a MET?
A MET (Metabolic Equivalent of Task) measures how much energy an activity uses compared with resting. Sitting quietly equals 1 MET, while running at 6 mph is about 9.8 METs, meaning your body burns energy nearly ten times faster than at rest. Researchers developed these values in the Compendium of Physical Activities, a widely accepted reference that supports exercise studies and calorie calculations.
What Is Calories Burned Calculator?
Calories Burned Calculator estimates how many calories you burn during physical activities based on your weight, exercise type, and workout duration. It uses MET values to calculate calories burned for each session and projects your weekly total from your exercise frequency. The calculator also estimates the equivalent amount of body fat burned, giving you a clearer picture of how regular exercise contributes to your long-term fitness goals.

Understanding Your Results
Our Calories Burned Calculator displays calories burned per session to show the energy used during one workout. Your weekly total multiplies that value by the number of exercise sessions you complete each week. It also estimates a fat-loss equivalent, helping you understand how regular workouts may contribute to long-term weight management.
Remember that every result in Calories Burned Calculator is an estimate. Daily calorie burn can change with your workout intensity, body weight, movement efficiency, and other personal factors. Use these numbers as a practical guide and update your information whenever your exercise routine changes.
Burning Calories More Effectively
Burning more calories is not only about spending extra time exercising. Small changes to your workout habits and daily routine can make each session more productive. Some special tips below explain how to improve your calorie burn and use your exercise results more effectively.
Getting More Out Of the Same Minutes
- Body Weight: A 200-lb person burns about 30% more calories than a 150-lb person doing the same workout.
- Exercise Intensity: 20 minutes at 10 METs burns more calories than 40 minutes at 4 METs, making higher intensity more time-efficient.
- Daily Movement: Walking, climbing stairs, and household chores can burn more calories than many gym sessions across an entire week.
Should You Eat Back Exercise Calories?
You should think carefully before eating back every calorie your workout burns. If your TDEE already includes an active lifestyle, your exercise calories are already part of your daily energy needs. Adding them again may lead to overeating. Fitness watches and trackers can also overestimate calorie burn. A practical approach is to count only about 50–75% of your estimated exercise calories, or choose a lower activity level and let your workouts create the extra calorie deficit naturally.
Frequently asked questions
How many calories does a 30-minute walk burn?
A 30-minute brisk walk (3.5 mph) burns about 140–210 kcal, depending on your body weight. This equals roughly 4.3 METs, and Calories Burned Calculator adjusts the estimate to your weight.
How many calories do 10,000 steps burn?
Most adults burn around 300–500 kcal from 10,000 steps. The exact number depends on your weight, walking speed, and terrain, with these steps equal to about 4–5 miles.
Which exercise burns the most calories?
Running, jump rope, and vigorous cycling reach about 10–12 METs, making them some of the highest calorie-burning exercises. The best exercise is still the one you can do consistently.
Why does my watch show more calories than this?
Fitness watches estimate calories from your heart rate and movement, so the result may differ. Studies show they often overestimate calorie burn by 15–30% or more, while MET-based estimates provide a more consistent reference.
