🔥 BMR & TDEE Calculator

How many calories does your body burn each day? Your BMR is what you burn at complete rest; your TDEE adds your daily activity. Both are the starting point for any weight plan.

How to use the BMR & TDEE Calculator

  1. Select your gender and enter your age, weight (kg) and height (cm).
  2. Choose the activity level that matches your normal week.
  3. Press Calculate — your BMR and TDEE appear below.
Example: A 30-year-old man weighing 70 kg at 175 cm has a BMR of about 1,649 kcal. With moderate activity (exercise 3-5 days a week), his TDEE is about 2,556 kcal per day.

Frequently Asked Questions

What is the difference between BMR and TDEE?

BMR is the energy your body needs at complete rest just to stay alive. TDEE (Total Daily Energy Expenditure) multiplies BMR by your activity level to estimate your real daily burn.

Which formula is used?

The Mifflin-St Jeor formula, considered the most accurate general estimate: for men 10×weight + 6.25×height − 5×age + 5; for women the same but − 161.

Is this a medical measurement?

No — it is a well-tested estimate. Individual metabolism varies; a doctor or dietitian can measure yours more precisely.
