How Many Calories I Need Per Day Calculator







Introduction

Knowing how many calories you need each day is crucial for managing your weight and overall health. Whether you want to maintain your current weight, lose weight, or gain weight, understanding your daily calorie requirements is the first step. Our “How Many Calories I Need Per Day Calculator” can help you determine the approximate number of calories you should consume to meet your goals.

Formula

This calculator uses the Harris-Benedict equation to estimate your Basal Metabolic Rate (BMR) based on your gender, age, weight, and height. The BMR represents the number of calories your body needs at rest. Then, it calculates your daily calorie requirements by applying an activity factor to your BMR. The formula is as follows:

For males: BMR = 66 + (6.23 * weight in pounds) + (12.7 * height in inches) – (6.8 * age in years)

For females: BMR = 655 + (4.35 * weight in pounds) + (4.7 * height in inches) – (4.7 * age in years)

Activity factors:

  • Sedentary (little or no exercise): BMR * 1.2
  • Lightly active (light exercise or sports 1-3 days a week): BMR * 1.375
  • Moderately active (moderate exercise or sports 3-5 days a week): BMR * 1.55
  • Very active (hard exercise or sports 6-7 days a week): BMR * 1.725
  • Super active (very hard exercise, physical job, or training): BMR * 1.9
