TDEE Calculator
Calculate your Total Daily Energy Expenditure using the Mifflin-St Jeor formula — the most accurate method for estimating daily calorie needs.
What is TDEE?
Your Total Daily Energy Expenditure (TDEE)is the total number of calories your body burns in a day — including exercise, daily movement, and basic bodily functions. It's the single most important number for body composition.
How is it calculated?
We use the Mifflin-St Jeor formula to calculate your Basal Metabolic Rate (BMR), then multiply by an activity factor. This is the formula most commonly used by registered dietitians and has the highest accuracy across populations.
