Welcome to tdeeclculator.com, your trusted source for accurate, easy-to-use calorie, macro, and body metric calculations. Whether you’re aiming to maintain your weight, build lean muscle, or create a sustainable fat-loss plan, our tool is designed with your goals in mind.
Why It Matters
Your total daily energy expenditure (TDEE) is the number of calories you burn each day, based on your body and how you move. Knowing your TDEE is the first step to tailoring a plan for weight loss, muscle gain, or maintenance. Our calculation handles everything from your basal metabolic rate (BMR) to activity levels, ideal weight formulas, and macro-targets—all in one place.
What Makes Us Different
Science-backed formulas & expanded metrics – We use the highly respected Mifflin-St Jeor equation to determine BMR, then apply standard activity multipliers. On top of that, we estimate ideal weight using multiple formulas (Hamwi, Devine, Robinson, Miller), assess BMI categories, and even estimate “maximum muscular potential” at 5 %, 10 % and 15% body fat.
One-page, no clutter interface – We know you don’t want extra steps or confusing dashboards. Our tool puts everything on a single responsive page with a clean layout and intuitive tabs (Metric or Imperial units).
Full transparency – You’ll always see how your numbers are derived, the formulas used, and how your activity level affects results. No hidden inputs, no surprise outcomes.
User-friendly design – Designed to work beautifully on any device, desktop, tablet, or mobile phone, so you can use it wherever you are without frustration.
