Calculate Calories

How It Works

The Calorie Calculator uses the Mifflin-St Jeor Equation to estimate your Basal Metabolic Rate (BMR), which is the number of calories your body needs at rest. This value is then multiplied by your activity level to estimate your total daily calorie needs.

Formulas Used

• For Men: BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age (years) + 5
• For Women: BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age (years) - 161

To lose weight, subtract 500 calories per day to lose approximately 1 pound per week. To gain weight, add 500 calories per day.
