Understanding your daily caloric needs is essential for maintaining a healthy weight. The Calories Weight Calculator is a handy tool that can help you estimate your daily calorie requirements based on your age, height, weight, and gender. In this article, we provide the calculator code and explain how it functions, offer guidance on using it effectively, provide an example, and answer frequently asked questions related to this keyword.


The Calories Weight Calculator utilizes the Harris-Benedict equation to estimate your Basal Metabolic Rate (BMR). The BMR is the number of calories your body needs to maintain basic functions at rest. The equation varies for males and females:

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

After calculating your BMR, the calculator provides an estimate of your daily caloric requirements.

How to Use

Utilizing the Calories Weight Calculator is straightforward. Follow these steps:

  1. Enter your age in years.
  2. Input your height in centimeters.
  3. Specify your weight in kilograms.
  4. Select your gender from the provided options.
  5. Click the “Calculate” button.

The calculator will determine your Basal Metabolic Rate (BMR) and display an estimate of your daily calorie requirements.


For example, if a 30-year-old female with a height of 160 cm and a weight of 65 kg uses the calculator, it would estimate her daily caloric requirements based on her BMR:

BMR = 447.593 + (9.247 x 65) + (3.098 x 160) – (4.330 x 30) = 1352.73 calories per day.
