BMR Calculator

Calculate your BMR

To determine your current BMR, please provide the following information:

What is your BMR?

Your BMR (Basal Metabolic Rate) is an estimate of how many calories you'd burn if you were to do nothing but rest for 24 hours. It represents the minimum amount of energy needed to keep your body functioning, including breathing and keeping your heart beating.

Your BMR does not include the calories you burn from normal daily activities or exercise.

Our calculator uses the Mifflin-St. Jeor equations to estimate your BMR which is believed to be more accurate than the more commonly used Harris-Benedict equation.
