TDEE Calculator: Estimate Calories fast in Under 2 Minutes

Use this TDEE calculator to estimate how many calories you burn per day based on your age, weight, height, gender, and activity level.

Your Total Daily Energy Expenditure (TDEE) represents the number of calories your body needs to maintain your current weight. Whether your goal is weight loss, muscle gain, or maintenance, knowing your TDEE gives you a clear starting point. This TDEE calculator gives you a fast, structured estimate you can use for realistic planning.

How to Use This TDEE Calculator

Select your preferred unit system (metric or imperial).
Enter your body weight.
Select your gender.
Enter your age.
Choose your activity level.
Enter your height.
The TDEE calculator will instantly display your estimated daily calorie requirement.

You can use this number to plan weight loss, maintenance, or muscle gain in a structured and evidence-based way.

How This TDEE Calculator Works

This TDEE calculator estimates how many calories your body needs each day to maintain your current weight in two steps:

It calculates your BMR (Basal Metabolic Rate)
It adjusts that number based on your activity level to estimate your TDEE

This approach is practical because your daily calorie needs depend both on your baseline metabolism and how active you are.

What Is BMR?

Before calculating TDEE, we first estimate your BMR (Basal Metabolic Rate).

BMR is the number of calories your body burns at complete rest. Even if you stayed in bed all day, your body would still need energy for:

Breathing
Circulation
Brain function
Organ function
Cell repair

Your BMR does not include exercise or movement. It only represents the calories required to keep you alive.

Factors that influence your BMR include:

Age
Gender
Height
Weight
Muscle mass

Generally, individuals with more muscle mass have a higher BMR.

What Is TDEE?

TDEE stands for Total Daily Energy Expenditure. It represents the total number of calories your body burns in a full 24-hour day.

This includes:

Calories burned at rest
Calories burned through daily movement
Calories burned during exercise
Energy used for digestion

Your TDEE is your body’s total energy output. If you consistently eat the same number of calories as your TDEE, your weight should remain stable over time.

If you eat less than your TDEE, you will gradually lose weight.
If you eat more than your TDEE, you will gain weight.

How Is TDEE Calculated?

TDEE is your BMR plus the calories you burn through daily activity such as walking, working, and exercise. The TDEE calculator uses your activity level to apply an appropriate multiplier, which turns a resting calorie estimate into a realistic daily number.

BMR vs TDEE: What’s the Difference?

Understanding the difference between BMR and TDEE is important:

BMR = Calories burned at rest
TDEE = BMR + activity + movement

Think of BMR as your baseline.
TDEE represents your full daily energy expenditure.

For practical diet planning, TDEE is the number you should focus on — and this TDEE calculator is designed specifically for that.

How to Use Your TDEE Results

Once you know your TDEE, you can adjust your calorie intake based on your goal.

For Weight Loss

Consume 300–500 calories below your TDEE.
This creates a sustainable calorie deficit for steady fat loss.

For Maintenance

Eat approximately your TDEE to maintain your current weight.

For Muscle Gain

Consume 200–300 calories above your TDEE.
A small surplus helps support muscle growth while limiting excess fat gain.

For best results, combine proper calorie intake with adequate protein and resistance training.
