BMR Calculator: Calculate Your Basal Metabolic Rate & Calorie Requirements

BMR Calculator
A BMR (Basal Metabolic Rate) calculator estimates the number of calories your body needs to maintain basic physiological functions while at rest, such as breathing, circulation, and cell production. This calculation is based on several factors, including age, gender, weight, and height. Knowing your BMR can help you understand your daily caloric needs and manage your weight more effectively.

BMR and Daily Calorie Calculator

This BMR calculator tool is highly accurate, using two well-established formulas to determine your daily calorie needs.

  1. Basal Metabolic Rate (BMR) Formula The BMR formula calculates your calorie requirements based on variables such as height, weight, age, and gender, assuming no physical activity.
  2. Harris Benedict Formula The Harris Benedict Formula adjusts the BMR value by considering your activity level, providing a more personalized calorie requirement.

However, this tool does not account for lean body mass or the muscle-to-fat ratio. Leaner bodies typically require more calories, so the calculator may slightly underestimate needs for very muscular individuals and overestimate for those who are significantly overweight. Despite this, the tool remains highly accurate for most users.
