Your Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a single day — including exercise, daily movement, and basic biological functions. Knowing your TDEE is the single most important number for achieving your health goals: whether you want to lose weight, gain muscle, or simply maintain where you are. This calculator uses the scientifically validated Mifflin-St Jeor equation to estimate your Basal Metabolic Rate (BMR) and then applies an activity multiplier to give you an accurate, personalised TDEE.
