Calculate your Basal Metabolic Rate in a few simple steps.
Input your current weight in the weight field.
Select male or female for accurate BMR calculation.
Provide your height using the available height input.
Input your age as BMR changes with age.
Review your Basal Metabolic Rate and daily calorie needs.
Basal Metabolic Rate (BMR) is the number of calories your body burns at rest to maintain basic physiological functions like breathing, circulation, and cell production.
Your BMR helps you understand your baseline calorie needs. Multiply your BMR by your activity level to determine daily calorie requirements for weight maintenance, loss, or gain.
The Mifflin-St Jeor equation is considered most accurate for modern populations. The calculator may show results from multiple formulas for comparison.
