TDEE Calculator

Calculate your total daily energy expenditure — the calories you actually burn per day including activity.

About this calculator

TDEE combines your basal metabolic rate with the energy cost of daily movement and exercise. It’s the anchor number for any calorie-based nutrition plan — deficits and surpluses are measured against it.

Formula

TDEE = BMR (Mifflin-St Jeor) × activity factor (1.2 – 1.9)
