What is BMR and TDEE?

Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions. Total Daily Energy Expenditure (TDEE) is the total calories burned in a day including activity.

Formula Used

This calculator uses the Mifflin-St Jeor Equation, considered the most accurate BMR formula:

• Men: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(y) + 5
• Women: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(y) - 161

TDEE = BMR × Activity Factor

When to Use This Calculator

• Weight loss or gain planning
• Understanding daily calorie needs
• Fitness and nutrition tracking
• Meal planning and diet management

Examples

Example 1: 70 kg, 175 cm, 25 y, male, sedentary → BMR: 1652.5 kcal, TDEE: 1983.0 kcal

Example 2: 60 kg, 165 cm, 30 y, female, moderate → BMR: 1288.0 kcal, TDEE: 1996.4 kcal
