BMR Calculator

The BMR Calculator (Basal Metabolic Rate) is a powerful and easy-to-use tool that helps you estimate the number of calories your body burns at rest. Your BMR represents the energy your body requires to perform basic life-sustaining functions such as breathing, circulation, and cell production — even when you’re not moving. Understanding your BMR is essential for managing weight, planning meals, and setting fitness goals.

This free online calculator uses the Mifflin-St Jeor equation, considered one of the most accurate methods for calculating BMR based on your gender, age, weight, and height. Whether you want to maintain, lose, or gain weight, knowing your BMR gives you the foundation for calculating your Total Daily Energy Expenditure (TDEE), which incorporates your activity level.

Perfect for fitness enthusiasts, nutritionists, or anyone interested in healthy living, our BMR calculator is mobile-friendly and delivers instant results. Take the guesswork out of your health plan and start optimizing your calorie intake today.
