TDEE Calculator

Understanding your Total Daily Energy Expenditure (TDEE) is the foundation of any successful fitness transformation. Our Free TDEE Calculator tells you exactly how many calories you burn in a 24-hour period based on your age, sex, height, weight, and most importantly your activity level.

Knowing your TDEE (also known as your "Maintenance Calories") allows you to eat with purpose. If you eat exactly your TDEE, your weight stays the same. To lose weight, you eat below it; to gain muscle, you eat above it. Our tool provides a precise roadmap so you can stop guessing and start seeing results.

What this tool calculates for you:

• Maintenance Calories: The daily energy required to keep your current weight.

• Basal Metabolic Rate (BMR): Your "coma calories" what you burn just by existing.

• Macronutrient Breakdown: Suggested grams of Protein, Fats, and Carbs for your goal.

• BMI (Body Mass Index): A quick check of your weight category.

• 100% Free & Fast: Professional-grade fitness math on HelpingWebTools.com.

What is the difference between BMR and TDEE? Your BMR (Basal Metabolic Rate) is the minimum energy your body needs to function (breathing, heart rate) while at rest. Your TDEE is your BMR plus the energy you burn through daily movement, work, and exercise.

Which activity level should I choose? Be honest! Most people overestimate their activity. If you work an office job and hit the gym 3 times a week, choose "Lightly Active." Only choose "Very Active" if you have a physical job (like construction) or train like an elite athlete daily.

Does TDEE change as I lose weight? Yes. As your body mass decreases, your body requires less energy to move. We recommend recalculating your TDEE every 2–4 weeks or after every 2kg (5 lbs) lost to keep your nutrition plan accurate.

Can I use this for my 2026 New Year's Resolution? Absolutely. Our formulas are updated for 2026 standards, ensuring you have the most accurate data to start your year off right.

Is my personal health data saved? No. At HelpingWebTools.com, we respect your privacy. Your height, weight, and age are used only for the calculation and are never stored on our servers.
