This activity based calorie burn calculator (also known as an "activity based caloric expenditure calculator") provides an estimate of the amount of calories that you burn while performing any selected activity from our database of over 600 activities.

Enter your gender, age, weight, and height into the calculator and then select your activity category from the "Activity Category" dropdown list. Once your activity category is chosen, select your specific activity from the "Activity" dropdown list and then enter the amount of time that you performed that activity for to estimate your calorie burn.

Note: This calculator provides gross calorie burn estimates. If you want to convert the estimate to net calorie burn, memorize the number and click here. If you want to learn more about net and gross calorie burn, read the Net Versus Gross Calorie Burn article.


This calculator is based on MET (Metabolic Equivalent) data for physical activities from "The Compendium of Physical Activities Tracking Guide" by B. E. Ainsworth. Each individual activity within this calculator has a MET value associated with it. A MET value represents the ratio of energy (i.e. calories) required to perform a particular activity relative to your BMR, where BMR is the amount of energy required to simply sit or lie quietly (while not digesting any food). The MET values are not displayed to you when you use the calculator, but they are entered into a formula that estimates your calorie burn by multiplying the MET value for your chosen activity by the duration time of your activity and by your calculated BMR. Estimation of BMR is based on the widely used and accepted Harris-Benedict equations. The equations used by this calculator are shown below:


For males: BMR = (13.75 x WKG) + (5 x HC) - (6.76 x age) + 66
For females: BMR = (9.56 x WKG) + (1.85 x HC) - (4.68 x age) + 655


BMR = Basal Metabolic Rate (over 24 hours)
MET = Metabolic Equivalent (for selected activity)
T = Activity duration time (in hours)
HC = Height (in centimetres)
WKG = Weight (in kilograms)
