Estimate Total Daily Energy Expenditure and view maintenance, cutting, and bulking calorie targets.
Total Daily Energy Expenditure is the estimated number of calories burned across a full day. It combines resting energy needs with movement, exercise, and the energy cost of processing food.
TDEE is commonly used to set calorie targets for weight maintenance, fat loss, or muscle gain. It gives a structured starting point for nutrition planning.
Total Daily Energy Expenditure, usually shortened to TDEE, is the estimated number of calories burned in a day. It is a common tool in nutrition planning because it helps set calorie targets based on whether the goal is to maintain weight, lose body fat, or gain mass.
This calculator estimates both BMR and TDEE, then provides example calorie targets and macro splits for maintenance, cutting, and bulking.
TDEE is not just exercise calories. It reflects the total energy used in a full day and is usually thought of as including:
This calculator can use two different approaches depending on the information available.
The Mifflin-St Jeor equation uses age, sex, weight, and height and is commonly used for general estimates.
The Katch-McArdle equation can be used when body fat percentage is known and may be more useful for people whose body composition differs from general averages.
Once BMR is estimated, it is multiplied by an activity factor. That produces a rough estimate of total calorie needs across a normal day.
The activity choice matters a lot. An inaccurate activity estimate can shift calorie targets meaningfully.
Once TDEE is known, calorie targets can be adjusted to fit a goal.
This tool uses simple example multipliers for each of those phases. In practice, the best size of deficit or surplus depends on the person, the pace of change wanted, and how training and recovery are going.
Calories matter, but macronutrient distribution matters too. This calculator offers several example macro profiles:
These profiles are planning tools rather than medical prescriptions. Actual macro choices often depend on training style, food preferences, adherence, and health context.
TDEE is not fixed. As body weight changes, training changes, or lifestyle changes, daily calorie needs usually change too.
That is why calorie targets often work best when reviewed and updated rather than treated as permanent.
A TDEE calculator gives an estimate, not a direct metabolic measurement. It can be very useful, but it still has limits.
The best use of TDEE is often as a starting point followed by real-world adjustment based on body weight trends, training performance, hunger, and recovery.
TDEE stands for Total Daily Energy Expenditure. It is the estimated number of calories burned in a full day, including rest, digestion, movement, and exercise.
BMR is the energy needed at complete rest to keep the body functioning. TDEE builds on that by including activity and daily movement.
It is an estimate, not a direct measurement. Real calorie needs vary with routine, body composition, training load, and individual metabolism.
Yes. As body weight, activity level, or training volume changes, calorie needs usually change too, so targets often need updating.
No. The calculator can work without it using the Mifflin-St Jeor equation, but body fat can improve the estimate when known.

TDEE is most useful as a planning estimate. It helps set a rational starting point, but the best results usually come from checking progress over time and adjusting intake based on real outcomes.
