About This Tool
The Calorie Calculator uses the Mifflin-St Jeor equation, considered the most accurate formula for estimating daily caloric needs. It factors in your age, gender, weight, height, and activity level.
Understanding your daily calorie requirements is essential for weight management, whether you want to lose, maintain, or gain weight. The calculator provides maintenance calories plus adjusted values for weight loss and gain.
Activity levels range from sedentary (little or no exercise) to extra active (very hard exercise or physical job). Choose the level that best matches your typical week for the most accurate results.
