The calorie calculator first determines your basal metabolic rate (BMR) using multiple factors, including height, weight, age and sex. It then multiplies that value by an activity factor that helps take into account your daily activities. This produces a value that approximates your total daily calorie requirement for maintaining your weight. The calculator will add or subtract a scientifically estimated amount of calories to or from the total.
