Understanding BMR Calculator
The BMR Calculator, or Basal Metabolic Rate Calculator, gives you an approximate number of calories per day your body needs at rest to maintain the basic physiological functions like breathing, circulation, etc. It is calculated based on age, gender, weight, and height, considering your body is totally at rest without any physical activity. The BMR calculator is also called the Harris Benedict calculator because it is based on the Harris Benedict equation, which is used to give an estimated basal metabolic rate. But recently the most used equation for BMR calculations is given by Mifflin-St Jeor. It is considered to be the most accurate and this BMR calculator is also based on this equation.
Formulas used for BMR calculators based on the Mifflin-St Jeor equation:
For Men:
BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) + 5
For Women:
BMR = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) – 161
As BMR calculator calculates basal metabolic rate which is the energy required when your body is at rest, if you want to calculate the calories required depending on your activity level then you can checkout our Calorie Calculator or TDEE Calculator.
