TDEE Calculator

Estimate your daily calorie needs using the Mifflin-St Jeor formula, the same method used by nutrition professionals worldwide. Enter your age, height, weight, biological sex, and activity level ranging from sedentary to very active and the app calculates your Basal Metabolic Rate and Total Daily Energy Expenditure in seconds. Results include four ready-to-use calorie targets: maintenance, mild cut for gradual weight loss, fat loss for a stronger deficit, and lean gain for muscle building. Metric and imperial measurements are both fully supported.
