Introduction
Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a day, including all activities – from basic life-sustaining functions to exercise and movement. Understanding your TDEE is essential for effective weight management, nutrition planning, and achieving your fitness goals. Our free TDEE Calculator helps you estimate your daily calorie needs based on your age, gender, height, weight, and activity level. This tool provides clear, personalized insights to help you plan your nutrition for weight loss, maintenance, or muscle gain.
This powerful tool uses the Mifflin-St Jeor formula to calculate your Basal Metabolic Rate (BMR) and then multiplies it by your activity factor to determine your TDEE. It runs entirely in your browser, keeps your personal data private, and requires no sign‑up. Combine it with our BMR calculator to understand your metabolism, our calorie calculator for comprehensive nutrition planning, or our fitness calculator for complete wellness planning.
What Is a TDEE Calculator?
A TDEE (Total Daily Energy Expenditure) Calculator is a health and fitness tool that estimates the total number of calories you burn in a day. TDEE is the sum of your Basal Metabolic Rate (BMR) – the calories you burn at complete rest – plus the calories burned through physical activity and the thermic effect of food. Understanding your TDEE is the foundation of effective weight management.
The calculator helps you answer important questions like:
- 🔥 How many calories do I burn each day?
- 📊 What calorie intake do I need for weight loss?
- 📈 How does my activity level affect my calorie needs?
- 🔄 What calorie surplus do I need for muscle gain?
Our TDEE Calculator uses the Mifflin-St Jeor formula for BMR calculation and provides tailored calorie recommendations for weight loss, maintenance, and weight gain. Use it alongside our BMR calculator to understand your metabolism, or our calories burned calculator to track exercise expenditure.

TDEE Calculation
TDEE is calculated using two steps: first calculating your BMR, then multiplying by your activity factor.
| Step | Formula | Description |
|---|---|---|
| BMR (Male) | (10 × weight kg) + (6.25 × height cm) – (5 × age) + 5 | Calories burned at complete rest |
| BMR (Female) | (10 × weight kg) + (6.25 × height cm) – (5 × age) – 161 | Calories burned at complete rest |
| TDEE | BMR × Activity Factor | Total daily calorie burn |
Activity Levels
Your activity level significantly affects your TDEE. Choose the level that best describes your lifestyle:
| Level | Description | Factor | Example Activity |
|---|---|---|---|
| Sedentary | Little or no exercise | 1.2 | Desk job, no exercise |
| Lightly Active | Light exercise 1-3 days/week | 1.375 | Walking, light gym |
| Moderately Active | Moderate exercise 3-5 days/week | 1.55 | Running 3-5 miles/week |
| Very Active | Hard exercise 6-7 days/week | 1.725 | Daily gym, competitive sports |
| Extra Active | Very hard exercise & physical job | 1.9 | Athlete, construction worker |
Calorie Goals Based on TDEE
Once you know your TDEE, you can adjust your calorie intake to achieve your goals:
| Goal | Adjustment | Rate of Change | Best For |
|---|---|---|---|
| Weight Loss | TDEE – 300-500 calories | 0.5-1 lb/week | Sustainable weight loss |
| Aggressive Loss | TDEE – 500-1000 calories | 1-2 lb/week | Short-term goals |
| Maintenance | TDEE | 0 lb/week | Weight maintenance |
| Muscle Gain | TDEE + 300-500 calories | 0.5-1 lb/week | Lean muscle growth |
Advanced Features That Make TDEE Planning Easy

Advantages and Benefits of Using Our TDEE Calculator
Why use our tool instead of rough estimates?
How the TDEE Calculator Works Internally
The TDEE Calculator uses two steps to estimate your daily calorie needs:
- Step 1 – BMR Calculation: Uses the Mifflin-St Jeor formula to estimate your Basal Metabolic Rate.
- Step 2 – TDEE Calculation: Multiplies your BMR by your selected activity factor to determine total daily calorie burn.
The calculator then provides calorie recommendations based on your goal:
- Weight Loss: TDEE – 300-500 calories (0.5-1 lb/week)
- Maintenance: TDEE
- Weight Gain: TDEE + 300-500 calories (0.5-1 lb/week)
All calculations are performed client‑side using JavaScript, ensuring speed and zero data transmission.

- Ignoring macronutrients: Calories are important, but macronutrient balance matters too.
- Not tracking progress: Track your weight and adjust your intake based on results.
Deep Dive: Understanding Total Daily Energy Expenditure
Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a day. It is composed of three main components:
- BMR (60-75%): Calories burned at complete rest to maintain basic life functions.
- Physical Activity (15-30%): Calories burned through exercise and daily movement.
- Thermic Effect of Food (10%): Calories burned digesting and processing food.
For example, consider a 30-year-old female weighing 70 kg (154 lbs), 165 cm (5’5″) tall, who is moderately active:
- BMR: (10 × 70) + (6.25 × 165) – (5 × 30) – 161 = 1,401 calories
- TDEE (Moderately Active, 1.55): 1,401 × 1.55 = 2,172 calories
- Weight Loss (500 deficit): 2,172 – 500 = 1,672 calories/day
- Weight Gain (500 surplus): 2,172 + 500 = 2,672 calories/day
Our TDEE Calculator handles all these calculations automatically, giving you accurate calorie insights instantly.
