TDEE Calculator

Use TDEE calculator to determine your Total Daily Energy Expenditure and (BMR). Get accurate calorie needs for weight loss, maintenance, or muscle gain.

What is TDEE (Total Daily Energy Expenditure)?

TDEE (Total Daily Energy Expenditure) is a scientific way to analyze the amount of calories your body burns each day. The calories your body uses when you are just at rest is called BMR (Basal Metabolic Rate) ; and when you add all your daily activities (movement, work, walking, exercise, etc.) to it, it becomes TDEE.

Why is it important to know TDEE?

For most health-conscious people in the United States, especially those looking to lose weight or gain muscle, knowing TDEE is an essential step. Because if you don’t know how many calories your body burns daily, you can never accurately follow a meal plan or fat loss/muscle gain program.

For example, if your TDEE is 2500 calories, then to lose weight you need to eat 20–25% fewer calories per day (calorie deficit), and to gain muscle you need a 10–15% more calorie intake (calorie surplus).

 TDEE vs BMR – What is the difference?

• BMR : This is the calculation of the number of calories your body needs each day to maintain its basic functions (breathing, blood circulation, cell repair, etc.).
• TDEE : This is the combined calorie expenditure of BMR + all types of activities (walking, working, exercising, digestion etc.).

Simply put: BMR is your body’s minimum calorie requirement TDEE is your actual calorie burn throughout the day

 From the combined EEAT and Semantic perspective:

• If you know your TDEE, you can accurately create a personalized calorie plan .
• It works primarily based on “daily calorie burn” , which also helps determine your “metabolism boosting strategies” .

How to Use the TDEE Calculator

The TDEE Calculator is extremely easy to use, but you will need to provide some basic inputs to get accurate results.

Initial input to be given:

1. Age – because metabolism slows down with age
2. Gender – BMR and muscle mass are different for men and women.
3. Weight – Input in pounds or kilograms.
4. Height – in feet+inches or centimeters
5. Activity Level – Select this according to your lifestyle:

Activity Level	Description
Sedentary	Sitting (very little/no exercise)
Lightly Active	Light walking or occasional workout
Moderately Active	Exercising 3–5 days a week
Very Active	Exercise 6–7 days a week
Extra Active	Intense exercise or physical work twice daily

This level determines your activity multiplier factor , which plays an important role in TDEE calculations.

 Activity Multiplier Factors: (NEAT, EAT, TEF explained)

1. NEAT (Non-Exercise Activity Thermogenesis) Daily involuntary movements—such as walking, working, standing
   
2. EAT (Exercise Activity Thermogenesis) Planned exercise—such as gym, cardio, weight training
   
3. TEF (Thermic Effect of Food) is the amount of calories your body burns while digesting food. It depends on the protein, fat, and carbs.
   

What is the formula used to calculate it?

One or more of the following formulas are used to determine TDEE:

1. Mifflin‑St Jeor Equation

The most common and proven method that takes into account weight, height, age and gender.

2. Katch‑McArdle Formula

It gives more accurate results for those who know their lean body mass.

3. Harris‑Benedict Equation

An early method, now somewhat outdated but still reliable.

How to Understand Your TDEE Results

What does Maintenance Calories mean?

Maintenance calories are the specific number of calories you eat each day that will keep your weight the same. This means you will neither gain nor lose weight. This number is the basis for calculating your TDEE. If you know that your maintenance level is 2,400 calories, then this will be your nutritional reference point.

Example (USA context): Maintenance calories for a 30-year-old, moderately active man might be around 2,500–2,800 calories, while for a woman it might be 1,900–2,200 calories.

 How to create a calorie deficit to lose weight?

The most scientific way to lose weight is to create a calorie deficit . This means that you eat fewer calories than your TDEE each day . Generally, eating 15–25% fewer calories is safe and effective.

Example: If your TDEE is 2,400 kcal, then for fat loss you can eat:

• ~2,000 kcal (medium deficit)
• ~1,800 kcal (aggressive but safe short term)

Thus, to lose 1 pound of weight, you need to create a deficit of ~3,500 calories per week.

Semantic inclusion:

• “Calorie requirements for weight loss”
• “calculate BMR and TDEE”

   

 How does calorie surplus work for muscle gain?

To build muscle, exercise alone isn’t enough— you need to give your body extra nutrition. This requires a calorie surplus , meaning you eat more calories than your TDEE.

Typically, a 10–15% calorie surplus is sufficient for muscle gain:

• If your TDEE is 2,400 kcal → then 2,650–2,800 kcal is required for muscle gain

This will only work if you are doing strength training or resistance workouts.

 Personalized Macro Goals এবং Planning

Knowing TDEE is not just about knowing calories—it helps you create the right Macronutrient split (Protein, Carb, Fat) .

Example:

• Weight Loss Macro Ratio: 40% protein / 30% fat / 30% carbs
• Muscle Gain Macro Ratio: 30% protein / 25% fat / 45% carbs

This ratio can change depending on your calorie intake. The results from the TDEE calculator in this section help you create an individualized meal plan .

 How to Create a Calorie Target Plan

How to set Daily/Weekly Calorie Goal?

After knowing TDEE, you have to decide—

• Do you want to lose weight?
• Or do you want to gain muscle?
• Or do you want to maintain your weight?

Your calorie guidelines according to your goal will be:

Goal	Daily Calorie Target	Weekly Change
Maintain	= TDEE	Weight unchanged
Fat Loss	TDEE – 500 (avg.)	~1 lb/week loss
Muscle Gain	TDEE + 250–300	~0.5 lb/week gain

This way you can easily create a practical & measurable goal.

 Safe Calorie Deficit Range for Weight Loss

• 15% Deficit = Sustainable fat loss
• 20–25% Deficit = Faster result but short term
• 30%+ Deficit = Unsustainable, risk of muscle loss

Especially for USA-based users who have a sedentary lifestyle (low mobility), too much deficit can be dangerous.

 Muscle Gain vs Fat Loss: Which should you do first?

• If you have high body fat (BMI > 25 or Waist/Hip ratio > 0.9), then lose fat first.
• If you are a lean body type, you can start with muscle gain.

One Goal At A Time = Best Result Cutting (fat loss) and Bulking (muscle gain) cannot be done together.

 “Protein Thermic Effect” and its importance

The body burns the most calories while digesting protein—this is called the Thermic Effect of Protein . So whether you want to lose weight or gain muscle, you need to increase your protein intake.

• 1g protein = 4 kcal, but its thermic effect is highest (~20–30% calories burned during digestion)

So for those who are trying to lose weight, a high protein diet is scientific & effective.

Summary

Your TDEE result isn’t just a number—it’s the foundation of a nutrition plan . Whatever your goal—to lose weight, gain weight, or maintain it—this number gives you a chance to understand your body.

Expert Tips to Boost Your Metabolism Scientific Ways to Increase Metabolism

Increasing your basal metabolic rate means your body burns more calories – even at rest. If you want to lose weight, increase your strength, or stay fit for the long term, knowing how to increase your metabolism is crucial. Below are some effective tips based on the opinions of US-based health experts and scientific research.

 1. Choose the right foods – “Metabolism Boosting Tips”

Eat high-protein foods: Eating protein causes the body to burn more calories in the digestive process. This is called the thermic effect of food (TEF) . Examples: Chicken breast, Greek yogurt, eggs, tuna, spinach, nuts.
Spicy foods: Capsaicin, a substance found in chili peppers, helps boost metabolism in the short term. However, consuming too much can cause digestive problems.
Green tea and coffee: Both the catechins and caffeine in green tea help increase metabolic rate. You can drink 2 cups of green tea a day.

 2. Personalize the right type of exercise

HIIT (High-Intensity Interval Training): This type of workout increases post-exercise oxygen consumption, which means the body burns calories even after exercise. Doing HIIT 3-4 days a week can yield quick results.
Weight Training/Resistance Training: Building muscle naturally increases your metabolism, as muscle tissue burns more calories than fat. Do weight lifting at least 2 days a week.

 3. The effects of sleep and stress

Lack of sleep slows down metabolism: According to research from the USA-based Harvard Medical School , not getting enough sleep reduces insulin sensitivity, which slows down metabolism. Ensure you get at least 7-8 hours of sleep a day.
Reduce stress: Chronic stress increases the hormone cortisol, which helps store fat and slows down metabolism. Follow activities like meditation, yoga, or walking.

 Use the right tools – accurate and personalized approach

Use an accurate calorie calculator: How many calories you should eat per day depends on your age, weight, height, and activity level. Our Calorie Calculator Tool does this job perfectly.

Set personalized macro goals: It’s important to know exactly how much carbs, protein, and fat you need each day. Our Macro Calculator will give you customized advice.

 Conclusion: There is no magic formula to boost metabolism, but if you develop science-based habits, you will definitely get long-term results. Proper diet, customized exercise, sleep, stress management – these are the 4 pillars that will help you improve your metabolic rate.

🔸 Frequently Asked Questions (FAQ)

How is TDEE calculated?

To calculate TDEE (Total Daily Energy Expenditure), you first need to determine your BMR (Basal Metabolic Rate), which is determined based on your age, weight, height, and gender. Then, the TDEE is calculated by applying a specific multiplier to BMR based on the level of physical activity you engage in every day—such as walking, exercising, running, or sitting at an office desk.

Example: If your BMR is 1500 and you are moderately active (do light exercise 3–5 days a week), then your TDEE will be approximately 1500 × 1.55 = 2325 calories.

This is an average calculation of how many calories you can eat per day to maintain your weight.

How do I reduce calories to lose weight?

To lose weight, you need to eat 15% to 25% fewer calories than your TDEE, creating a calorie deficit. This calorie deficit forces your body to burn stored fat for energy.

For example, if your TDEE is 2400 calories, you can eat about 1800–2000 calories per day to lose weight. This calorie reduction plan should include a diet rich in protein and fiber, plenty of water, and regular exercise.

How many calories are needed for muscle gain?

To gain muscle, you need to be in a calorie surplus, meaning you need to eat a little more calories than your body burns. Generally, eating 10%–15% more calories than your TDEE is considered optimal for muscle gain.

If your TDEE is 2600 calories, then you can eat 2850–3000 calories per day to gain muscle. But it’s not just about increasing calories—daily protein intake, progressive strength training, and adequate sleep are also important.

Are TDEE and BMR the same?

No, TDEE and BMR are not the same thing. BMR (Basal Metabolic Rate) refers to how many calories the body burns each day while at rest—to maintain things like breathing, blood circulation, hormone secretion, etc. It is a measure of the energy required to keep the body’s basic functions running.

TDEE (Total Daily Energy Expenditure) is the total daily calorie expenditure, which includes physical activity, exercise, digestion of food, and minor movements in addition to BMR.

In short:

• BMR = Resting state calorie expenditure
• TDEE = Total Daily Calorie Expenditure including all activities
