Advanced BMR & TDEE Calculator
Calculate Your Basal Metabolic Rate and Total Daily Energy Expenditure
Advanced BMR Calculator – Accurately Calculate Your BMR and TDEE
Welcome to our free and advanced BMR Calculator! Accurately estimate how many calories your body burns at rest (BMR) and find out your Total Daily Energy Expenditure (TDEE) based on your age, gender, height, weight, and physical activity level. Knowing your BMR and TDEE can help you create a well-structured fitness or diet plan that matches your personal goals.
🔥 What is BMR (Basal Metabolic Rate)?
BMR represents the number of calories your body burns to maintain essential bodily functions like breathing, circulation, nutrient processing, and cell production while completely at rest. It is the minimum number of calories your body requires to function properly. Knowing your BMR can help you set realistic fitness, weight loss, or muscle gain goals.
Your BMR depends on several factors, including age, gender, height, weight, and body composition. As you age or lose muscle mass, your BMR tends to decrease. That’s why it becomes crucial to regularly monitor your BMR to align your nutrition and fitness strategies effectively.
🏃♂️ What is TDEE (Total Daily Energy Expenditure)?
Your TDEE is the total amount of calories you burn daily when you account for all activities such as walking, exercising, working, and even sleeping. TDEE includes your BMR plus calories burned through physical activity. Understanding your TDEE helps you plan how many calories you should consume depending on your goal – whether it’s weight loss, maintenance, or muscle gain.

📚 Factors Affecting Your BMR
- 🔹 Age: BMR decreases as you get older.
- 🔹 Gender: Men usually have a higher BMR due to more muscle mass.
- 🔹 Body Composition: More muscle mass equals a higher BMR.
- 🔹 Hormones: Thyroid hormones play a significant role in regulating metabolism.
- 🔹 Genetics: Your genes can influence your basal metabolic rate.
- 🔹 Diet: Eating habits and nutritional intake also influence metabolism speed.
💬 Frequently Asked Questions (FAQ)
Q: How often should I calculate my BMR and TDEE?
A: It’s recommended to recalculate your BMR and TDEE every 2-3 months or whenever you experience significant weight changes.
Q: Which formula is best for calculating BMR?
A: The Mifflin-St Jeor Equation is widely accepted for its accuracy in calculating BMR compared to other older methods like the Harris-Benedict Equation.
Q: Can BMR and TDEE calculations help in muscle building?
A: Yes! Understanding your TDEE helps you set a calorie surplus which is essential for muscle gain, while monitoring BMR ensures you’re not overeating.
Q: Is it possible to increase BMR naturally?
A: Yes, by building lean muscle mass, staying active, drinking enough water, eating enough protein, and avoiding drastic calorie cuts, you can boost your BMR naturally.
