The BMR Calculator is a free online tool designed to calculate your basal metabolic rate (bmr)—the energy expended at complete rest. It allows you to perform these calculations quickly and accurately without manual computations.

Enter your biological gender, age, height, and weight. The result is the absolute baseline calorie burn before accounting for active energy output. Once you enter these values, the calculator will automatically compute and display the results instantly.

The BMR Calculator uses the following formula to calculate your results: BMR (Mifflin-St Jeor Formula): Male: 10w + 6.25h - 5a + 5 Female: 10w + 6.25h - 5a - 161 (weight in kg, height in cm) This formula is standard and widely accepted for these types of calculations.

Sure! Here is a practical example: A 30-year-old female weighing 170 lbs (77.1 kg) and measuring 68 in (172.7 cm) has an estimated BMR of 1,515 kcal/day. This example demonstrates how the inputs are processed through the formula to yield the final results.

To use the BMR Calculator, you need to enter: Age, Gender, Weight (lbs), Height (inches). These inputs help the tool calculate precise results tailored to your situation.

The BMR Calculator outputs the following details: Basal Metabolic Rate. This comprehensive breakdown helps you understand the different aspects of the calculated figures.
