What Is The Formula For Calculating Calories

When it comes to maintaining a healthy lifestyle, understanding your daily calorie needs is crucial. Whether you’re trying to lose, gain, or maintain your weight, knowing the number of calories your body requires can be a game-changer. In this article, we will provide a simple calculator to determine your daily calorie needs and explain the formula behind it.


The formula for calculating daily calorie requirements is based on various factors, including weight, height, age, and gender. Here’s the formula in plain text:

  • For males:
    • Calories = 88.362 + (13.397 * weight in kg) + (4.799 * height in cm) – (5.677 * age in years)
  • For females:
    • Calories = 447.593 + (9.247 * weight in kg) + (3.098 * height in cm) – (4.330 * age in years)

This formula provides an estimate of the number of calories your body needs to maintain your current weight.

How to Use

To calculate your daily calorie requirements, follow these simple steps:

  1. Enter your weight in kilograms in the “Enter Weight” field.
  2. Enter your height in centimeters in the “Enter Height” field.
  3. Enter your age in years in the “Enter Age” field.
  4. Select your gender from the dropdown list.
  5. Click the “Calculate” button.

The result will be displayed below, indicating the number of calories you need per day.


Let’s say you are a 30-year-old male weighing 75 kilograms and standing 175 centimeters tall. Using the formula for males:

Calories = 88.362 + (13.397 * 75) + (4.799 * 175) – (5.677 * 30) Calories ≈ 1763.55 calories per day

So, a 30-year-old male with these measurements would need approximately 1763.55 calories per day to maintain their current weight.
