TDEE Calculator

Total Daily Energy Expenditure is the total number of calories you burn in a full 24-hour cycle. TDEE comprises four primary components: BMR (~70%), NEAT (~15%), EAT (~5-10%), and TEF (~10%).

Formula & Calculation Methodology

TDEE = BMR × Activity Multiplier. Activity levels are indexed: Sedentary (desk work, minimal movement) = 1.2; Light (1-2 workouts/wk or active walking) = 1.375; Moderate (3-5 workouts/wk) = 1.55; Heavy (6-7 intense sessions/wk) = 1.725; Athlete (twice-daily training) = 1.9.

Formula Model: Physical Activity Level (PAL) Multipliers

Practical Example & Interpretation

If your BMR is 1,500 kcal and you work an office job but train with weights 4 times per week (Moderate Activity = 1.55), your estimated TDEE is 2,325 kcal/day.

Assumptions & Clinical Disclaimers

People frequently overestimate exercise burn and underestimate non-exercise movement. If your weight does not change after two weeks at your calculated TDEE, treat your actual intake as your real maintenance level.
