Calorie Calculator

Calculate your daily calorie needs (TDEE)

How to Use This Calculator

This calculator uses the Mifflin-St Jeor equation to estimate your Basal Metabolic Rate (BMR) and then applies an activity factor to determine your Total Daily Energy Expenditure (TDEE).

Understanding the Results

  • Maintain Weight: This is your TDEE. Eating this amount will keep your weight stable.
  • Lose Weight: A deficit of 500 calories per day typically results in 1 lb (0.45 kg) of weight loss per week.
  • Gain Weight: A surplus of 500 calories per day helps in building muscle and gaining weight.
