BMR Calculator


Result :


A Basal Metabolic Rate (BMR) calculator is a valuable tool that helps estimate the number of calories your body burns while at rest. It's a fundamental component in understanding your overall energy expenditure. By taking into account essential factors like age, weight, height, and gender, this calculator provides insights into your body's fundamental caloric needs. The calculation method for BMR depends on your gender.

If you are a male, the BMR is calculated as follows:

[BMR = 88.362 + (13.397 * weight in kilograms) + (4.799 * height in centimeters) - (5.677 * age in years)]

If you are a female, the BMR calculation is slightly different:

[BMR = 447.593 + (9.247 * weight in kilograms) + (3.098 * height in centimeters) - (4.33 * age in years)]

Whether you're male or female, it's essential to note that BMR is an estimate and may vary among individuals due to factors like muscle mass, body composition, genetics, and more. It serves as a valuable starting point, best used alongside guidance from a healthcare professional to gain a more accurate understanding of your specific calorie requirements and health objectives.

BMR represents the number of calories your body requires to maintain essential physiological functions, such as breathing, circulation, and cell production, when at rest. It signifies the energy needed to sustain life in a state of complete rest.


For example, let's consider a 30-year-old female who weighs 65 kilograms and is 1.65 meters tall. Substituting these values into the formula for a female:

[BMR = 447.593 + (9.247 * 65) + (3.098 * 165) - (4.33 * 30)]

Simplifying this equation:

[BMR = 447.593 + 601.055 + 511.77 - 129.9]

[BMR = 1430]

Therefore, this individual's estimated BMR is approximately 1430 calories per day. This represents the number of calories her body requires to maintain essential functions in a state of complete rest.

Understanding your BMR serves as a foundational step in determining your daily calorie needs. To maintain, gain, or lose weight, you must take into account your activity level and total daily energy expenditure (TDEE). By factoring in physical activity, you can calculate the number of calories needed to maintain your current weight or reach your desired objectives. Nonetheless, it's crucial to bear in mind that BMR is a starting point, and consulting with a healthcare professional or registered dietitian is highly recommended for personalized guidance on your nutritional and health journey.
