Estimate your Basal Metabolic Rate (BMR)- The energy necessary for maintenance of life processes such as heart beat, breathing and cell metabolic activities.

Enter the required information. Enter your Body Fat percentage if you know it. Click "Calculate".

To estimate your BMR, we use the Harris-Benedict equation (Sex, Age, Height and Weight) or the Katch-McArdle equation (Weight and Body Fat). The Harris-Benedict formula somewhat overestimates BMR for obese people.

If you have had your body composition tested and you know your body fat percentage, enter it to get more accurate BMR estimate.
