Mifflin-St Jeor Formula Male ( 10 x Weight in KGs ) + ( 6.25 x Height in CMs ) - ( 5 x Age ) + 5 Female ( 10 x Weight in KGs ) + ( 6. Click the Estimate Your Level button to find your physical activity level. A Biometric Study of Human Basal Metabolism. This formula excludes the activity level factor usually included in the above formulas to provide an accurate BMR calculation. The NIH Body Weight Planner calculates a personalized calorie level to help. The difference between the equations shown above and those on the Daily Caloric Expenditure Calculator is illustrative of the actual meaning of BMR. In the Daily Caloric Expenditure Calculator, BMR was multiplied by the "Activity Level Factor" to account for daily physical activity levels and the thermic effect of food (thereby providing an estimate of the total amount of calories you burn in a day), but these factors are not a consideration when determining BMR. The equations above are exactly the same as those used for our Daily Caloric Expenditure Calculator, except that the "Activity Level Factor" that is used for the Daily Caloric Expenditure Calculator has been removed here. This calculator will tell you the number of calories per day you should consume to maintain your existing weight based on the resting BMR. These factors are used to determine your resting BMR. These include age, gender, weight and height.

After you find your BMR use one of these multipliers to find the amount. There are several variables that are used in the BMR calculation. Male (metric): BMR = (13.75 x WKG) + (5 x HC) - (6.76 x age) + 66 The activity factor takes into account everything you do in a day not just training.This calculator is based on the widely used and accepted Harris-Benedict equations for BMR.
