BMR & TDEE Calculator
Calculate your Basal Metabolic Rate and Total Daily Energy Expenditure
About this calculator
The BMR & TDEE Calculator helps you determine your Basal Metabolic Rate (BMR) - the calories your body burns at rest - and your Total Daily Energy Expenditure (TDEE) - the total calories you burn including physical activity. This information is essential for creating effective weight loss, weight gain, or maintenance plans. Understanding your metabolic rate allows you to set appropriate calorie targets based on your individual physiology and lifestyle, making your fitness and nutrition goals more achievable and scientifically sound.
How to use
Enter your age, gender, height, and weight to calculate your BMR. Then select your activity level (sedentary, lightly active, moderately active, very active, or extremely active) to determine your TDEE. The calculator will instantly display both values, showing how many calories you burn daily at rest and with your current activity level.
Frequently asked questions
What's the difference between BMR and TDEE?
BMR is calories burned at rest for basic body functions. TDEE includes BMR plus calories burned through daily activities and exercise.
How accurate are BMR calculations?
BMR calculators provide estimates within 10-15% accuracy for most people. Individual metabolism can vary based on genetics, muscle mass, and health factors.
How often should I recalculate my BMR and TDEE?
Recalculate every 10-15 pounds of weight change, significant activity level changes, or every 3-6 months for accurate calorie targets.
