Your TDEE is the number of calories you burn per day. Eat below it to lose weight, above it to gain, or right at it to maintain. Our calculator uses the Mifflin-St Jeor formula — the most scientifically accurate BMR equation — and multiplies by your activity level.

Choose from five activity levels: sedentary (desk job, no exercise), light activity (1-3 days/week), moderate (3-5 days), active (6-7 days), or very active (physical job + training).

Formula
TDEE = BMR (Mifflin-St Jeor) × Activity Factor

FAQ

What is TDEE?
TDEE (Total Daily Energy Expenditure) is the total number of calories you burn each day — from basic functions (BMR) plus daily activity and exercise.
How accurate is this?
Mifflin-St Jeor BMR is ~95% accurate. Activity factors are broad guidelines; for precision, track calories with a food scale for 2-3 weeks.
