The Basal Metabolic Rate (BMR) Calculator is an essential tool for anyone interested in understanding how many calories their body burns at rest. Whether you’re planning a weight loss program, designing a fitness routine, or simply curious about your body’s energy needs, this calculator gives you the accurate insights you need to make smarter health decisions.
Your BMR is the number of calories your body requires to perform basic life-sustaining functions like breathing, circulation, and cell production — even when you’re doing absolutely nothing. This value is calculated using the Mifflin-St Jeor Equation, one of the most widely accepted formulas in modern nutrition science. It takes into account your age, gender, weight, and height to estimate how much energy your body uses in a 24-hour resting state.
BMR Calculator
Our BMR Calculator is designed to be simple, responsive, and intuitive. You can toggle between Metric (kg/cm) and Imperial (lbs/ft+in) units depending on your preference or location. After entering your basic information, one click of the calculate button instantly provides your BMR in calories per day. The result is displayed in a clean, styled box that helps you understand your result at a glance.
While the BMR itself is not your total daily calorie needs, it serves as the foundation for further calculations like TDEE (Total Daily Energy Expenditure) or Calorie Needs. For example, by applying an activity multiplier to your BMR, you can estimate how many calories you should consume to maintain, lose, or gain weight.
Whether you’re a fitness coach, a diet planner, or an individual working toward a healthier lifestyle, this BMR Calculator helps you start with precision. No sign-up required, no app to download—just accurate results, right when you need them.
