Calculate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) based on your stats and activity level.
Your Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic functions at complete rest — breathing, circulation, cell production, and temperature regulation.
This calculator uses the Mifflin-St Jeor equation, the most accurate formula for most adults according to modern research. Your TDEE (Total Daily Energy Expenditure) multiplies your BMR by an activity factor to estimate your real-world calorie needs.
