What Is the BMR Calculator?
Your Basal Metabolic Rate (BMR) is the number of calories your body burns at complete rest just to maintain basic functions like breathing, circulation, and cell production. It accounts for about 60-75% of your daily calorie burn.
The Formula
Mifflin-St Jeor: Men 10xweight(kg)+6.25xheight(cm)-5xage+5. Women 10xweight+6.25xheight-5xage-161.
Example
A 35-year-old man at 5 foot 10 inches (178 cm) and 175 pounds (79 kg) has a BMR of approximately 1,765 calories per day using the Mifflin-St Jeor equation. A 30-year-old woman of identical height and weight has a BMR of roughly 1,600 calories.
Common Uses
Weight management, meal planning, fitness programming, nutrition coaching.
