Total Daily Energy Expenditure (TDEE), i.e. total daily energy expenditure, is the estimated number of calories you burn during the day, taking into account basic life functions and all your activity. Our TDEE calculator helps you check in just a few seconds how much energy you really need to maintain weight, lose weight or build muscle mass - without guessing or counting "by eye".

What is TDEE?
TDEE (Total Daily Energy Expenditure), in Polish total daily energy expenditure, is the sum of all the calories your body burns during the day:
- calories needed for breathing, heart function, regeneration - the so-calledBMR,
- energy used for everyday activities (walking, work, home),
- calories burned during training and sports activity,
- cost of digestion and absorption of meals (the so-called thermic effect of food).
Knowledge of TDEE is the foundation of any sensible dietetics and training planning. Until you know how many calories you are actually burning, it is very difficult to:
- build an effective calorie deficit on cutting,
- set a reasonable surplus on muscle mass,
- maintain your current weight without fluctuations up and down.
The TDEE calculator allows you to quickly estimate your daily calorie requirement, based on standard and proven equations (including BMR + activity multiplier), and then provides the result in a form that you can immediately use in practice - in the menu, in a calorie counting application or in a training plan.
How to use the TDEE Calculator step by step
In order for the calculator to give you the most accurate result, it needs some basic information about you. The whole process takes less than a minute:
- Select the measurement system
Decide whether you want to enter data in the following system:- metric- kilograms and centimeters,
- imperial- pounds and inches.
- Enter gender
Select whether you arefemaleormale. The BMR and TDEE equations take into account physiological differences, so gender has a real impact on the result. - Enter age
Enter yourcurrent age. With age, basal metabolism most often gradually decreases, so this parameter is important in calculations. - Enter weight and height
Enter:- weight(in kg or lb),
- height(in cm or inches).
- Specify your level of physical activity
Select the option that best describes your typical week:- sedentary lifestyle- mainly office work, little exercise,
- slightly active- walking, occasional training 1-2 times a week,
- moderately active– regular training 3-4 times a week,
- very active– intensive training 5-6 times a week, physical work,
- extremely active– competitive sport, several training units a day.
- (Optional) Enter your body fat percentage
If you know your approximate% body fat%, you can enter it toincrease the accuracy of your BMR. The percentage of body fat can be estimated:- using a simple caliper,
- based on circumference measurement and online calculators,
- based on body composition analysis (e.g. in a fitness club).
- Click "Calculate"
After completing the fields, run the calculator. In a few seconds you will see:- estimated TDEE,
- BMR - basal metabolic rate,
- BMI - body mass index,
- proposed macronutrient distribution (protein, fat, carbohydrates).
All calculations are performed automatically - you don't need to know formulas or manually calculate calories. You enter your data, select the activity, click "Calculate" and you have a ready base for creating a diet tailored to your goal.
How to read TDEE calculator results?
After the calculation, the calculator presents several key values. Each of them says something different about your body and helps you make sensible diet and training decisions.
TDEE - Total Daily Energy Expenditure
This is the number of calories that - according to the model - you burnon average during the day, at the given activity level. If:
- you eat less than your TDEE - you create adeficitand over time you lose weight,
- you eat as much as your TDEE - in the long run you maintain your weight,
- you eat more than your TDEE - you create asurplus, which is conducive to weight gain.
TDEE is therefore the starting point for: reduction, weight and maintenance. The calorie plan tailored to your goal is based on this number.
BMR - Basal Metabolic Rate
BMR (Basal Metabolic Rate)is the number of calories that the body burns atrestif you just lay down, breathed and maintained basic life functions (organ function, body temperature, regeneration) all day long.
BMR shows how much energy your body uses "in the background", regardless of exercise or work. Too low a calorie intake below BMR for a long time may negatively affect:
- well-being,
- energy level,
- hormones,
- regeneration and training effects.
BMI – Body Mass Index
BMI (Body Mass Index)is a simple indicator that compares your weight to your height. It doesn't distinguish between muscle and fat, but it does give you a general idea of whether your weight is within the typical range for your height.
BMI can be helpful asquick screening, especially for people not involved in competitive sports. In athletes with a lot of muscle mass, this indicator may be less reliable.
Macronutrients - protein, fat, carbohydrates
Based on your TDEE, the calculator can proposedistribution of energy into macro:
- protein- crucial for muscles, satiety and regeneration,
- fat- important for hormones, nervous system and absorption of vitamins,
- carbohydrates- the main fuel during training and exercise.
Thanks to this, you not only know how many calories to consume per day, but also how to divide them more or less into individual groups of ingredients to make the diet more functional and easier to maintain.
How to use TDEE for weight loss, weight loss and weight maintenance?
The TDEE score itself is just a starting point. Below you will find the simplest way you can "translate" your calorie count into a practical action plan - depending on your goal.
Reduction - you want to lose weight
If your goal isto reduce body fat, the starting point is to create acaloric deficitrelative to TDEE. The typical approach is:
- a deficit of approximately 10-20% below TDEE,
- slow, steady weight loss without drastic cuts,
- maintaining an adequate protein intake to protect muscles.
Example: if your TDEE is 2400 kcal, start with approximately 1900-2100 kcal per day and monitor the rate of weight loss and how you feel. If necessary, you can slightly adjust your caloric intake every few weeks.
Mass - you want to gain weight or build muscle
Toincrease yourbody mass (especially muscle mass), you need acaloric surplusover your TDEE. It is usually recommended to:
- a surplus of approximately 5-15% above TDEE,
- combine it with resistance (strength) training,
- control the rate of weight gain to minimize fat storage.
Example: TDEE 2400 kcal - start with approximately 2600-2800 kcal per day and monitor the increase in weight and strength during training.
Maintenance - You want to maintain your current weight
If you are happy with your current weight and body shape, you can use TDEE as yourcalorie goalon a daily basis. All you need to do is:
- eat an amount of calories close to the calculated TDEE,
- ensure a minimum dose of exercise per week,
- control your weight from time to time, correcting your diet by small amounts.
Slight fluctuations in weight from week to week are natural - long-term trends are important, not individual measurements.
Recomposition – fat reduction and muscle building at the same time
For some people (especially beginners or after a break),recompositionis possible, i.e. simultaneous improvement of body composition without major changes in weight. TDEE will help you:
- set your calories close to zero balance (close to TDEE),
- select the appropriate macro distribution with an emphasis on protein,
- combine it with strength training and sensible regeneration.
In this approach, the weight may remain the same, but the circumference, appearance and strength significantly improve.
Top Benefits of Knowing Your TDEE
Knowing your TDEE is more than just a number. It is a practical tool that allows you to make decisions based on data, not guesswork.
- More effective weight management– you know how much to eat to move in the planned direction.
- Better diet planning- you choose the calorie and macro content consciously, instead of "by feel".
- Adjusting the training plan– you can match the training volume with the energy supply.
- Awareness of your own body- you see how age, weight and lifestyle affect your metabolism.
- Health support– it is easier to avoid extreme diets and the yo-yo effect.
Example scenarios of using the TDEE calculator
Below are some simple examples of how you can use the calculator in practice:
- Start reducing:calculate TDEE, subtract about 15% of calories, set a diet and observe how the scale reacts for 2-3 weeks.
- After you have finished the diet:you use your TDEE as a reference point to gradually return to a maintenance calorie level and avoid rapid weight gain.
- When planning your training season:you check your TDEE at the beginning of your training period and update it as your weight or activity changes.
- When working with a trainer or dietician:the result from the calculator serves as a basis for further individual adjustment of the plan.
- Progress check every few months:as your weight, age and shape change, you update your TDEE so that the diet is still adequate to your situation.
Frequently Asked Questions (FAQ)
How often should I calculate my TDEE?
It is worth converting TDEE whenever one of the key parameters changes: weight, activity level, lifestyle or goal (reduction, mass, maintenance). In practice, for most people, updating every few months or after a weight change of a few kilograms is enough.
Is TDEE important if I don't train?
Yes.TDEE matters for every, even in the absence of regular training. It helps you choose the amount of calories so as not to unconsciously gain weight and maintain a healthy energy balance in everyday life.
Is the TDEE from the calculator 100% accurate?
Each TDEE calculator is amathematical model– gives a very good approximation, but does not know all the details of your physiology. Treat the result as a starting point, and then monitor your weight, circumference and well-being for several weeks. If necessary, adjust calories up or down by small amounts.
What if I don't know my body fat percentage?
Entering body fat % isoptional. Without it, the calculator will still calculate your BMR and TDEE based on your age, height, weight and gender. If you later know your approximate BF%, you can repeat the calculation to make the result a little more precise.
Does TDEE change as I lose or gain weight?
Yes. As your weight, body composition and activity level change, your daily energy expenditure changes. Therefore, after a major weight change, it is worth using the calculator again and adjusting the calorie content of the diet to the current situation.
