How the Calorie Calculator Works

    The First Step to Controlling Your Weight

    Understanding how many calories your body needs per day is the first step towards any goal, whether it's losing weight, gaining mass, or simply maintaining a healthy lifestyle. Calories are the energy your body uses to function.

    To find out your personalized caloric goal, use our Calorie Calculator .

    Important Concepts: BMR and TDEE

    Basal Metabolic Rate (BMR)

    The number of calories your body burns at complete rest, just to keep vital organs functioning.

    Represents 60-70% of your total daily expenditure.

    Total Daily Energy Expenditure (TDEE)

    The total number of calories you burn in a day, including BMR and physical activities.

    TDEE = BMR × Activity Level

    How the BMR Calculation is Done

    Mifflin-St Jeor Equation (most accurate)

    For Men

    BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5

    For Women

    BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161

    Example (woman, 30 years, 60kg, 165cm):
    BMR = (10 × 60) + (6.25 × 165) - (5 × 30) - 161 = 1320 kcal

    Activity Levels (TDEE Multiplier)

    Sedentary

    Little to no exercise

    BMR × 1.2

    Lightly Active

    Light exercise 1-3 days/week

    BMR × 1.375

    Moderately Active

    Moderate exercise 3-5 days/week

    BMR × 1.55

    Very Active

    Intense exercise 6-7 days/week

    BMR × 1.725

    Extremely Active

    Very intense exercise/physical job

    BMR × 1.9

    Setting Your Goal

    Lose Weight

    Create a calorie deficit. Start with 15-20% less than your TDEE.

    TDEE - 500 kcal/day

    Maintain Weight

    Consume an amount of calories equal to your TDEE.

    TDEE

    Gain Mass

    Create a calorie surplus. Start with 10-15% more than your TDEE.

    TDEE + 300 kcal/day
