What is TDEE?

TDEE stands for Total Daily Energy Expenditure. It is the total number of calories your body burns in a single day based on your Basal Metabolic Rate (BMR) and your activity level. Understanding your TDEE is essential for anyone looking to lose weight, build muscle, or maintain their current physique. While BMR covers the calories burned while at rest, TDEE accounts for every movement, from walking to the kitchen to high-intensity gym sessions.

How to Use This TDEE Calculator

To get an accurate estimation of your daily caloric needs, simply enter your gender, age, weight, and height into the fields above. Selecting the correct activity level is crucial; most people tend to overestimate their physical activity. For the most accurate result, choose "Sedentary" if you have a desk job and do not exercise, and scale up only if you are consistently active throughout the week.

Frequently Asked Questions

Can I lose weight by eating my TDEE?

No, eating exactly your TDEE will result in weight maintenance. To lose weight, you need to create a caloric deficit, typically by consuming 500 calories less than your TDEE. Conversely, to gain weight, you should consume a surplus.

How accurate is this formula?

This tool uses the Mifflin-St Jeor Equation, which is widely considered the most accurate standard for calculating BMR and TDEE. However, individual factors like muscle mass and hormonal health can cause variations.

Should I adjust my TDEE as I lose weight?

Yes. As your body weight decreases, your TDEE will also drop because a smaller body requires less energy to function. It is recommended to recalculate your TDEE every 5-10 pounds lost.
