What is TDEE and why does it matter?

TDEE (Total Daily Energy Expenditure) is the total calories your body burns daily at rest plus activity. Knowing your TDEE helps you set accurate calorie targets for weight loss, maintenance, or gain.

How accurate is this calorie calculator?

This calculator uses the Mifflin-St Jeor equation, the most accurate formula for estimating TDEE. Results are typically within 10-20% of your actual needs; individual variation depends on metabolism, muscle mass, and genetics.

What activity levels should I select?

Sedentary = desk job, no exercise; Lightly Active = 1-3 workouts/week; Moderately Active = 3-5 workouts/week; Very Active = 6-7 workouts/week; Extremely Active = physical job or twice-daily training.

Does this calculator work on mobile?

Yes, works perfectly on iPhone, Android, tablets, and desktop. The responsive design adapts to any screen size with easy-to-tap buttons and readable input fields.

Is my personal data saved or shared?

No. All calculations happen in your browser only. Your age, weight, and other data are never stored, logged, or sent to servers. Complete privacy guaranteed.

How do I calculate calories for weight loss?

Take your TDEE result and subtract 500 calories for 1 pound per week loss, or 750 calories for 1.5 pounds per week. Never go below 1,200 calories (women) or 1,500 calories (men) daily.

Can I use this calculator if I'm overweight or underweight?

Yes, this calculator works for all body types and weight ranges. It calculates your personal TDEE based on current measurements, making it accurate whether you're underweight, normal weight, or obese.
