# How To Calculate How Many Calories You Need

Introduction: Determining the right amount of calories your body needs is essential for maintaining a healthy lifestyle. This calculator provides a personalized approach, taking into account your weight, height, age, gender, and activity level to estimate the daily calorie requirement.

Formula: The formula for calculating the Basal Metabolic Rate (BMR) is different for males and females. For males: BMR = 10 * weight + 6.25 * height – 5 * age + 5. For females: BMR = 10 * weight + 6.25 * height – 5 * age – 161. The Total Daily Energy Expenditure (TDEE) is then calculated by multiplying the BMR with an activity factor based on your selected activity level.

How to Use: Enter your weight, height, age, select your gender and activity level, and click the “Calculate” button. The result will show the estimated number of calories you need per day.

Example: For a 30-year-old female with a weight of 65 kg, height of 160 cm, and a moderately active lifestyle, the calculator might reveal a daily calorie requirement of approximately 2000 calories.
