TDEE Calculator

Calculate your Total Daily Energy Expenditure and find out how many calories to eat.

What is TDEE?

TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns in a day, including your base metabolism, daily activities, and exercise. Knowing your TDEE helps you determine how many calories to eat to lose weight, maintain weight, or build muscle. This calculator uses the Mifflin-St Jeor equation, which is considered the most accurate formula for estimating metabolic rate.

How This Works

Your body burns calories just by existing. To lose weight, eat fewer calories than you burn. To gain weight, eat more. It's that simple.

Tips for Success

  • • Track your food for at least a week
  • • Weigh yourself weekly, same time each day
  • • Adjust calories if you're not seeing results after 2-3 weeks
  • • Eat plenty of protein to preserve muscle
