Daily Calorie Calculator

How to Use This Daily Calorie Calculator

Your Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a day. It is calculated from your Basal Metabolic Rate (BMR) — the calories needed to maintain basic body functions — multiplied by an activity factor. Knowing your TDEE is the foundation of any nutrition plan. Enter your measurements above for an instant result based on established health guidelines.

Understanding Your Results

Sedentary: BMR × 1.2

Lightly active: BMR × 1.375

Moderately active: BMR × 1.55

Very active: BMR × 1.725

The Formula

BMR (Mifflin-St Jeor): Men: 10×weight(kg) + 6.25×height(cm) − 5×age + 5
