Estimate your Total Daily Energy Expenditure (TDEE) using the Mifflin-St Jeor Formula.
Reaching your fitness goals—whether that means losing weight, building lean muscle, or maintaining your current physique—starts with understanding your body’s daily energy burn. Trying to guess your daily calorie needs often leads to stalled progress, unexpected weight gain, or unnecessary fatigue from under-eating.
Instead of following generic meal plans or guessing numbers, an accurate TDEE Calculator provides clear, personalized target calories based on your body metrics and daily movement. Our free web utility evaluates your age, gender, height, weight, and activity level to reveal your total daily energy expenditure in seconds.
Â
Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns over a full 24-hour period. Your total daily burn is made up of four primary components:
Â
Using a dedicated TDEE Calculator Tool combines these variables into a unified daily total, helping you establish an accurate baseline for weight management.
Â
Calculating energy expenditure accurately involves different mathematical formulas depending on available data:
Â
Our Free TDEE Calculator automates these equations, serving as a flexible Calories Per Day Calculator that helps you find your ideal balance without doing manual algebra.
Â
Calculating your daily energy burn requires realistic entries. A few frequent mistakes can skew your results:
Â
Refining your daily energy targets over time ensures steady, predictable progress toward your fitness targets:
Â
Using a structured Calorie Intake Calculator helps you adjust calorie targets smoothly whenever your training schedule or goals shift.
Â
BMR is the baseline energy your body burns at complete rest, while TDEE includes BMR plus all calories burned through daily movement, work, and exercise.
To lose weight steadily, subtract 300 to 500 calories from your calculated TDEE. This creates a sustainable deficit of roughly 0.5 to 1 pound of weight loss per week.
Recalculate your energy expenditure every time you lose or gain 5 to 10 pounds, or whenever your regular weekly exercise routine changes noticeably.
If you work a sedentary desk job and exercise 3 times a week, select “Lightly Active” rather than “Moderate” to prevent overestimating your daily burn.
Yes. Muscle tissue requires more metabolic energy to maintain than fat tissue, meaning increasing muscle mass naturally boosts your baseline BMR and overall expenditure.
Yes. The interface is fully responsive and works smoothly on smartphones, tablets, and desktop web browsers.
No. All calculations process locally inside your active web browser tab session. We do not track, collect, or store any of your private body metrics.
Â
Understanding your body’s daily energy burn takes the guesswork out of nutrition planning, meal preparation, and weight management. By using an accurate online tool to process your body metrics and daily activity levels, you gain total control over your calorie targets and fitness journey.
