Calories Burned Calculator
Estimate calories burned during exercise and daily activities based on activity type, duration, and body weight.
A calories burned calculator estimates energy expenditure during physical activities using MET values, helping you plan workouts and balance your calorie intake.
Examples
Running 30 minutes at 170 lbs
Frequently Asked Questions
What are MET values?
Are these calorie estimates accurate?
Quick Tips
- •Use calorie burn estimates for relative comparisons between activities rather than exact tracking.
- •Combine higher-MET activities with strength training for the most efficient calorie burning over time.
- •A heart rate monitor provides a more personalized calorie burn estimate than MET-based formulas.

How to Use This Calculator
Select your activity from the dropdown, enter the duration in minutes, and provide your weight. Click Calculate to see an estimate of calories burned based on MET (Metabolic Equivalent of Task) values.
Understanding the Formula
Calories Burned = MET x Weight (kg) x Duration (hours). MET values represent the energy cost of physical activities as a multiple of resting metabolic rate.
Examples
Running 30 minutes at 170 lbs
A 170 lb (77 kg) person running at 6 mph (MET 9.8) for 30 minutes burns approximately 9.8 x 77 x 0.5 = 377 calories.
Frequently Asked Questions
What are MET values?
MET (Metabolic Equivalent of Task) is a measure of the energy cost of physical activity. 1 MET equals the energy you burn at rest. An activity with a MET of 5 burns 5 times the energy of sitting still.
Are these calorie estimates accurate?
MET-based calculations provide reasonable estimates but actual calories burned depend on factors like fitness level, body composition, exercise intensity variations, and environmental conditions. They are most useful for relative comparisons between activities.
Assumptions & Limitations
- MET values are population averages — actual calorie burn varies with fitness level, intensity, and technique.
- Does not account for the afterburn effect (excess post-exercise oxygen consumption) from high-intensity workouts.
- Body composition affects results — muscular individuals may burn more calories than the estimate suggests.
