TDEE Calculator

What is TDEE (Total Daily Energy Expenditure)?

TDEE represents the total number of calories your body burns in a day, including all activities from basic metabolic functions to physical exercise. Understanding your TDEE is crucial for effective weight management, whether your goal is to lose, maintain, or gain weight.

TDEE is calculated by combining your BMR (Basal Metabolic Rate) with your activity level. BMR is the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production, while activity calories account for everything from walking to intense workouts.

How to Calculate Your TDEE

Our calculator makes TDEE calculation simple and accurate:

Select Your Unit System: Choose between Metric (cm, kg) or Imperial (inches, pounds)
Enter Your Age: Input your current age in years
Select Your Gender: Choose Male or Female (this affects BMR calculation)
Enter Your Height: Input your accurate height measurement
Enter Your Weight: Input your current weight
Select Activity Level: Choose from:
- Sedentary: Little or no exercise
- Light: Exercise 1-3 days per week
- Moderate: Exercise 3-5 days per week
- Active: Exercise 6-7 days per week
- Very Active: Hard exercise daily or physical job

The Formula:

Our calculator uses the Mifflin-St Jeor Equation to calculate BMR:

Men: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(years) + 5
Women: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(years) - 161

TDEE = BMR × Activity Multiplier

Understanding Your TDEE Results

BMR (Basal Metabolic Rate)

This is the number of calories your body burns at complete rest. It accounts for 60-75% of your total daily calorie expenditure and represents the energy needed for basic bodily functions.

Activity Calories

These are the additional calories burned through daily activities and exercise. The more active you are, the higher this number will be.

Calorie Goals

Based on your TDEE, we provide three calorie targets:

Weight Maintenance: Eat at your TDEE to maintain current weight
Weight Loss: 500 calories below TDEE (approximately 1 lb/week loss)
Weight Gain: 500 calories above TDEE (approximately 1 lb/week gain)

Activity Levels Explained

Accurately selecting your activity level is crucial for getting the right TDEE calculation:

Sedentary (Multiplier: 1.2)

Little or no exercise, desk job. Most of your day is spent sitting.

Light (Multiplier: 1.375)

Light exercise 1-3 days per week. You might take walks or do light household activities.

Moderate (Multiplier: 1.55)

Moderate exercise 3-5 days per week. Regular workouts like jogging, cycling, or gym sessions.

Active (Multiplier: 1.725)

Hard exercise 6-7 days per week. Intense workouts or physically demanding job.

Very Active (Multiplier: 1.9)

Very hard exercise daily or physical job. Professional athletes or extremely active individuals.

Tips for Using Your TDEE

•
Be Honest About Activity Level: Overestimating your activity can lead to consuming too many calories, while underestimating may cause excessive calorie restriction.
•
Recalculate Regularly: As your weight changes, your TDEE changes. Recalculate every 5-10 pounds of weight change.
•
Start with Maintenance: If you're new to calorie tracking, start by eating at your TDEE for a week to see how your body responds.
•
Adjust Based on Results: TDEE is an estimate. Monitor your weight and adjust your calorie intake based on actual results.
•
Consider Professional Guidance: For significant weight changes or health conditions, consult with a registered dietitian or healthcare provider.

Frequently Asked Questions About TDEE

Q: What is TDEE?

A: TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns in a day, including your BMR (Basal Metabolic Rate) and calories burned through physical activity.

Q: How is TDEE calculated?

A: TDEE is calculated by multiplying your BMR (calculated using the Mifflin-St Jeor equation) by an activity multiplier based on your daily physical activity level.

Q: What's the difference between BMR and TDEE?

A: BMR (Basal Metabolic Rate) is the number of calories your body burns at rest. TDEE includes BMR plus calories burned through daily activities and exercise.

Q: How accurate is the TDEE calculator?

A: Our calculator uses the scientifically validated Mifflin-St Jeor equation for BMR calculation, which is considered one of the most accurate formulas. However, individual results may vary based on metabolism, body composition, and other factors.

Q: Should I eat my TDEE to maintain weight?

A: Yes, consuming calories equal to your TDEE will help you maintain your current weight. To lose weight, create a calorie deficit (typically 500 calories per day for 1 lb/week loss). To gain weight, consume more than your TDEE.

Q: How often should I recalculate my TDEE?

A: Recalculate your TDEE when your weight changes significantly (5-10 lbs), when your activity level changes, or every few months to ensure accuracy as your body composition may change.
