About TDEE Calculator
Empowering your fitness journey with accurate, science-based calculations
Our Mission
At TDEE Calculator, we believe that understanding your body's energy needs is the foundation of any successful fitness journey. Whether you're looking to lose weight, gain muscle, or maintain your current physique, knowing your Total Daily Energy Expenditure (TDEE) is crucial for making informed decisions about your nutrition and exercise.
Our mission is to provide you with accurate, science-based tools and information that empower you to take control of your health and fitness goals. We combine the precision of the Mifflin-St Jeor equation with user-friendly design to make calorie calculation accessible to everyone.
What is TDEE?
Total Daily Energy Expenditure (TDEE) represents the total number of calories you burn in a day, including:
- Basal Metabolic Rate (BMR): The calories your body needs at rest to maintain basic functions
- Physical Activity: Calories burned through planned exercise and sports
- Non-Exercise Activity: Energy used in daily activities like walking, typing, and fidgeting
- Thermic Effect of Food: Energy required to digest, absorb, and process food
By understanding your TDEE, you can create a personalized nutrition plan that aligns with your specific goals, whether that's creating a caloric deficit for weight loss, a surplus for muscle gain, or maintaining your current weight.
