Total Daily Energy Expenditure Calorie Calculator

How This Calculator Works

This calculator estimates your daily calorie needs using the Mifflin-St Jeor Equation, one of the most widely accepted methods for calculating Basal Metabolic Rate (BMR).

BMR (Basal Metabolic Rate) is the number of calories your body needs to stay alive at complete rest. It includes essential functions such as breathing, heart activity, brain function, and cell repair. In simple terms, BMR represents the calories you burn doing nothing all day.

Step 1: Calculate BMR

Men: BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) + 5
Women: BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) − 161

Step 2: Adjust for Activity Level

TDEE = BMR × Activity Level
  • Sedentary: 1.2
  • Light activity: 1.375
  • Moderate activity: 1.55
  • Active: 1.725

Step 3: Goal-Based Adjustments

  • Fat Loss: TDEE − 500 calories
  • Maintenance: TDEE
  • Gain Weight: TDEE + 250 calories

This TDEE calculator provides an estimate of your daily calorie needs based on standardized formulas and self-reported inputs such as age, weight, height, and activity level. Actual energy expenditure may vary due to factors including metabolism, body composition, hormonal balance, and lifestyle.
