About Calorie & TDEE Calculator

Free Online Calorie & TDEE Calculator

Calculate maintenance calories, BMR, weight loss deficits, and macronutrient targets. Designed for creators, developers, students, and business professionals who demand high-speed processing, absolute privacy, and seamless usability without software installation.

What is Calorie & TDEE Calculator?

The Calorie and TDEE Calculator determines your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) using the scientifically validated Mifflin-St Jeor equation. Whether your goal is weight loss, muscle gain, or weight maintenance, knowing your daily energy requirements is the foundation of effective nutrition planning. Enter your age, gender, height, weight (Metric or Imperial), and physical activity level to calculate maintenance calories, structured weight loss deficits (-250 kcal mild, -500 kcal standard), weight gain surpluses (+250 kcal, +500 kcal), and optimal daily macronutrient targets (Protein, Carbohydrates, and Healthy Fats).

Calorie & TDEE Calculator Formula & Calculation Method

Mathematical Equation

BMR (Men) = 10W + 6.25H - 5A + 5 | BMR (Women) = 10W + 6.25H - 5A - 161

Mifflin-St Jeor equation calculates Basal Metabolic Rate and daily TDEE energy needs.

Variables & Breakdown

Weight in kilograms.

Height in centimeters.

Age in years.

TDEE

Total Daily Energy Expenditure = BMR × Activity Multiplier (1.2 to 1.9).

Worked Example Calculation

Input Data: Male, Weight = 75kg, Height = 180cm, Age = 30, Lightly Active

Step Calculation: BMR = (10×75) + (6.25×180) - (5×30) + 5 = 1730 kcal; TDEE = 1730 × 1.375

Final Result: Daily Maintenance Calories = 2,378 kcal

Frequently Asked Questions

What is the difference between BMR and TDEE?

BMR (Basal Metabolic Rate) is the number of calories your body burns at complete rest to stay alive. TDEE (Total Daily Energy Expenditure) is your BMR multiplied by your physical activity level to reflect total daily calorie burn.

How many calories should I cut for safe weight loss?

A moderate deficit of 500 kcal per day typically results in safe, sustainable fat loss of approximately 0.5 kg (1 lb) per week.

What macronutrient split is recommended?

A balanced macro distribution is 30% Protein, 40% Carbohydrates, and 30% Healthy Fats, which provides energy for workouts while supporting muscle retention.

Is Calorie & TDEE Calculator completely free to use?

Yes, Calorie & TDEE Calculator is 100% free with no hidden fees, subscriptions, or usage limits. You can use it as many times as you need without creating an account.
