Free BMR Calculator
Find out your Basal Metabolic Rate (BMR) to understand the minimum calories your body needs at rest. A key metric for weight management and fitness planning.
What Your BMR Tells You
Your Basal Metabolic Rate (BMR) is a measure of the energy your body uses just to stay alive. It's the number of calories you would burn if you stayed in bed all day. Understanding your BMR is the first step in creating a successful diet or fitness plan, as it helps you calculate your total daily calorie needs.
BMR vs. TDEE
While BMR is your baseline calorie burn, your Total Daily Energy Expenditure (TDEE) accounts for your activity level. To get a full picture of your daily calorie needs for weight loss or maintenance, you can use your BMR as a starting point and then use our all-in-one Health Calculator to determine your TDEE.
