TDEE Calculator
Knowing how many calories your body actually needs each day is the foundation of effective nutrition planning. The TDEE Calculator is a browser-based tool that helps you estimate your total daily energy expenditure based on your body measurements and activity level.
Instead of guessing calorie intake or following generic diet advice, this calculator gives you a clear daily calorie estimate that reflects how much energy your body uses. Whether your goal is weight maintenance, fat loss, or performance support, understanding your TDEE helps you make informed food and activity decisions.
What Is a TDEE Calculator?
A TDEE Calculator estimates the total number of calories your body burns in a day. This includes calories used for basic bodily functions as well as physical activity. TDEE stands for Total Daily Energy Expenditure.
TDEE is calculated by combining your basal metabolic rate (BMR) with an activity factor. BMR represents the calories your body needs at rest to maintain vital functions such as breathing, circulation, and temperature regulation.
Unlike simple calorie charts, a TDEE calculator adjusts for individual factors like age, gender, height, weight, and activity level. The result is a personalized estimate that helps guide daily calorie intake. For scientific background on energy expenditure, see Total daily energy expenditure on Wikipedia.
Why Use This TDEE Calculator?
Manually estimating calorie needs often leads to under- or over-eating. The TDEE Calculator simplifies calorie planning by applying established metabolic formulas and activity multipliers.
This tool is useful because it offers:
- Accuracy: Based on widely used metabolic equations
- Speed: Instant results with no calculations required
- Convenience: No apps, spreadsheets, or tracking tools
- Clarity: Results shown as daily calorie needs
For users already planning nutrition with a Macro Calculator or managing intake using a Protein Intake Calculator, this calculator provides the calorie baseline those tools rely on.
How to Use the TDEE Calculator

- Input your height and age.
- Select your gender.
- Choose your activity level.
- Click Calculate TDEE.
- View your estimated daily calorie expenditure.
For best accuracy, select the activity level that reflects your typical week, not occasional workouts.

TDEE Formula and Measurements
The TDEE (Total Daily Energy Expenditure) Calculator operates in two main steps.
Step 1: Calculate BMR
One commonly used equation is the Mifflin-St Jeor formula.
For men
BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) + 5
For women
BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) − 161
Step 2: Apply Activity Factor
TDEE = BMR × Activity Multiplier
Common multipliers:
- Sedentary: 1.2
- Lightly active: 1.375
- Moderately active: 1.55
- Very active: 1.725
- Extremely active: 1.9
Example
If BMR is 1,600 and activity level is moderate:
1,600 × 1.55 = 2,480 calories per day

Frequently Asked Questions
What does TDEE mean?
TDEE stands for Total Daily Energy Expenditure, the total calories burned in a day.
Is TDEE the same as BMR?
No. BMR measures calories burned at rest, while TDEE includes activity.
Can TDEE help with weight loss?
Yes. Knowing TDEE helps create a calorie deficit or surplus.
How often should I recalculate TDEE?
Recalculate when weight, activity level, or lifestyle changes.
Is TDEE accurate for everyone?
It provides an estimate. Individual metabolism may vary.
