Daily Calorie Needs Calculator (US Units)

How We Calculate Caloric Needs

BMR Formula (Mifflin-St Jeor Equation):

• Male: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5
• Female: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 161

Total Daily Calories = BMR × Activity Factor

Activity Factors: Sedentary=1.2, Lightly active=1.375, Moderately active=1.55, Very active=1.725, Extra active=1.9
