The Calorie Calculator is a free online tool designed to estimate the number of daily calories required to maintain, lose, or gain weight. It allows you to perform these calculations quickly and accurately without manual computations.

Provide your statistics and active lifestyle level. Enter your body fat percentage to use the lean mass formula. Standard TDEE results and a customizable macronutrients breakdown table are generated. Once you enter these values, the calculator will automatically compute and display the results instantly.

The Calorie Calculator uses the following formula to calculate your results: BMR (Mifflin-St Jeor): Male = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) + 5 Female = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) - 161 BMR (Katch-McArdle, if body fat is entered): BMR = 370 + 21.6 * [ weight(kg) * (1 - body_fat/100) ] TDEE = BMR * Activity Multiplier This formula is standard and widely accepted for these types of calculations.

Sure! Here is a practical example: A 25-year-old male, 160 lbs (72.6 kg), 70 in (177.8 cm), active level 1.55, BMR = 1,692 kcal (using Mifflin). With 15% body fat BMR becomes 1,699 kcal (using Katch-McArdle). This example demonstrates how the inputs are processed through the formula to yield the final results.

To use the Calorie Calculator, you need to enter: Age, Gender, Weight (lbs), Height (inches), Activity Level, Body Fat Percentage (Optional). These inputs help the tool calculate precise results tailored to your situation.

The Calorie Calculator outputs the following details: Maintain Weight, Mild Weight Loss (-0.5 lb/wk), Weight Loss (-1 lb/wk), Weight Gain (+1 lb/wk). This comprehensive breakdown helps you understand the different aspects of the calculated figures.
