BMR Calculator

This calculator calculates BMR(Basal Metabolic Rate).

BMR is the minimum number of calories necessary for sustaining basic functions for the body.

There are several ways of calculating BMR like the Mifflin-St Jeor Equation and the Revised Harris-Benedict Equation but a study has shown that the Mifflin-St Jeor Equation is more accurate.

Output values are rounded to the first decimal place.

Mifflin-St Jeor Equation

Male: BMR = 10W + 6.25H - 5A + 5

Female: BMR = 10W + 6.25H - 5A - 161


Revised Harris-Benedict Equation

Male: BMR = 13.397W + 4.799H - 5.677A + 88.362

Female: BMR = 9.247W + 3.098H - 4.33A + 447.593


BMI Equation

BMI = W ÷ H2
