BMR Online Calculator

What is BMR Online?

BMR (Basal Metabolic Rate) Online is a free calculator that determines how many calories your body burns at complete rest. This is the minimum number of calories needed to maintain basic bodily functions like breathing, circulation, and cell production.

Our BMR Online calculator uses the Mifflin-St Jeor Equation, which is considered the most accurate method for calculating BMR. It's essential for anyone planning a diet, weight loss program, or nutrition plan.

Understanding Your BMR Results

Your BMR represents the calories your body needs at complete rest. However, most people are active throughout the day, so the calculator also shows your TDEE (Total Daily Energy Expenditure) based on different activity levels:

• Sedentary (1.2x BMR): Little or no exercise, desk job
• Light Activity (1.375x BMR): Light exercise 1-3 days/week
• Moderate Activity (1.55x BMR): Moderate exercise 3-5 days/week
• Very Active (1.725x BMR): Hard exercise 6-7 days/week
• Extra Active (1.9x BMR): Very hard exercise, physical job, or training twice/day
