BMR & Calorie Calculator
Estimate how many calories your body burns at rest and in total each day. Enter your age, gender, height, weight and activity level to get your BMR and TDEE.
How It Works & Formula
BMR is estimated using the Mifflin-St Jeor equation, and TDEE is BMR x activity factor. Your activity level adjusts calories for daily movement and exercise.
