TDEE Calculator | Total Daily Energy Expenditure Calculator
Calculate your TDEE (Total Daily Energy Expenditure) with our advanced calculator. Plan your calories for weight loss, maintenance, or muscle gain with detailed macronutrient breakdown.
The TDEE (Total Daily Energy Expenditure) Calculator is an essential fitness tool that helps you calculate how many calories your body burns in a day. TDEE represents the total number of calories you need to maintain your current weight, considering your basal metabolic rate (BMR) and activity level. This calculator helps you plan weight loss, maintenance, or muscle gain effectively.
What is TDEE?
Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a 24-hour period. It includes your Basal Metabolic Rate (BMR) - calories burned at rest, plus calories burned through physical activity, exercise, and digestion (thermic effect of food). Understanding your TDEE is crucial for effective weight management and fitness planning.
TDEE Calculation Formula
BMR Calculation (Mifflin-St Jeor Equation):
For Men: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(y) + 5
For Women: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(y) - 161

Activity Level Definitions
Sedentary
Little or no exercise, desk job (BMR × 1.2)
Lightly Active
Light exercise 1-3 days/week (BMR × 1.375)
Moderately Active
Moderate exercise 3-5 days/week (BMR × 1.55)
Very Active
Hard exercise 6-7 days/week (BMR × 1.725)

Calorie Scenarios
| Profile | Age | Activity Level | BMR | TDEE | Weight Loss (500cal deficit) |
|---|---|---|---|---|---|
| Male, 180cm, 80kg | 30 | Moderately Active | 1,800 cal | 2,790 cal | 2,290 cal |
| Female, 165cm, 60kg | 25 | Lightly Active | 1,350 cal | 1,856 cal | 1,356 cal |
| Male, 175cm, 70kg | 40 | Sedentary | 1,620 cal | 1,944 cal | 1,444 cal |
| Female, 170cm, 65kg | 35 | Very Active | 1,400 cal | 2,415 cal | 1,915 cal |
Weight Management Strategies
Weight Loss
- 500 calorie deficit = ~1 lb (0.45 kg) loss per week
- 750 calorie deficit = ~1.5 lb (0.68 kg) loss per week
- 1000 calorie deficit = ~2 lb (0.9 kg) loss per week
- Minimum recommended: 1200 calories/day for women, 1500 for men
Weight Maintenance
- Eat calories equal to your TDEE
- Monitor weight weekly
- Adjust ±100-200 calories as needed
- Focus on nutrient-dense foods
Muscle Gain
- 250-500 calorie surplus per day
- Focus on protein intake (1.6-2.2g/kg body weight)
- Combine with resistance training
- Expect 0.25-0.5 kg muscle gain per week
Macronutrient Guidelines
Protein
4 calories per gram. Essential for muscle repair and growth. Recommended: 1.6-2.2g per kg of body weight for active individuals, 0.8g per kg for sedentary.
Carbohydrates
4 calories per gram. Primary energy source. Recommended: 45-65% of total calories. Focus on complex carbs (whole grains, vegetables, fruits).
Fats
9 calories per gram. Essential for hormone production and nutrient absorption. Recommended: 20-35% of total calories. Focus on healthy fats (avocado, nuts, olive oil).
Important Considerations
- TDEE calculators provide estimates - individual metabolism may vary
- Adjust calories based on weekly progress and feedback
- Consult healthcare professional before starting extreme diets
- TDEE changes with weight loss/gain - recalculate every 4-6 weeks
- Account for non-exercise activity thermogenesis (NEAT)
- Quality of calories matters as much as quantity
Frequently Asked Questions
How accurate is the TDEE calculator?
TDEE calculators provide estimates based on population averages. Individual variations can be ±10-15%. The most accurate method is to track your food intake and weight for 2-3 weeks and adjust based on actual results.
How often should I recalculate my TDEE?
Recalculate every 4-6 weeks or after significant weight change (±5 kg/10 lbs). As you lose weight, your BMR decreases, so you'll need to adjust your calorie intake to continue progressing.
What's the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is calories burned at complete rest. TDEE (Total Daily Energy Expenditure) includes BMR plus calories burned through activity, exercise, and digestion. TDEE = BMR × Activity Multiplier.
How do I choose my activity level?
Be honest about your daily routine. Sedentary = desk job, little exercise. Lightly Active = light exercise 1-3 days/week. Moderately Active = moderate exercise 3-5 days/week. Very Active = hard exercise 6-7 days/week or physical job.
