Understanding what is a tdee calculator is essential for anyone serious about weight management. Whether how do i calculate my tdee for weight loss, muscle gain, or maintenance, our tool provides accurate results using the Mifflin-St Jeor formula with optional body fat adjustment.

📐 2. How to Calculate TDEE
How to calculate TDEE in two simple steps:
📌 Step 1: Calculate Your BMR
Men: BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) + 5
Women: BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) − 161
📌 Step 2: Multiply by Activity Level
Sedentary (1.2): Little or no exercise
Lightly Active (1.375): Light exercise 1-3 days/week
Moderately Active (1.55): Moderate exercise 3-5 days/week
Very Active (1.725): Hard exercise 6-7 days/week
Extra Active (1.9): Athlete or physical job
TDEE = BMR × Activity Factor
Our tdee calculator does all this automatically. Just enter your details and get instant results!
📊 3. TDEE Formula Explained
The TDEE formula uses the Mifflin-St Jeor equation, considered the most accurate for general populations:
Formula
Male
Female
Mifflin-St Jeor
(10×W) + (6.25×H) - (5×A) + 5
(10×W) + (6.25×H) - (5×A) - 161
Katch-McArdle
370 + (21.6 × Lean Body Mass)
W = weight in kg, H = height in cm, A = age in years
For best results, use the tdee calculator with body fat option which uses the Katch-McArdle formula for greater accuracy.
