Calorie Calculator
Estimate daily maintenance calorie expenditure (TDEE) based on your Basal Metabolic Rate and physical activity level.
TDEE estimates daily maintenance calorie expenditure based on activity multipliers. This is an informational estimate, not clinical medical advice.
Estimate your daily maintenance calorie needs (Total Daily Energy Expenditure / TDEE) based on your BMR and activity level.
[!NOTE] Calorie calculations are general estimates for healthy adults. They are not intended as clinical dietary prescriptions or medical advice.
Formula & Method
- TDEE Formula:
Daily Maintenance Calories = BMR × Activity Multiplier
Activity Multipliers:
- Sedentary:
1.20 - Light Exercise (1-3 days/wk):
1.375 - Moderate Exercise (3-5 days/wk):
1.55 - Very Active (6-7 days/wk):
1.725 - Extra Active:
1.90
Worked Example
For a 30-year-old male (BMR = 1,730 kcal) with moderate exercise:
TDEE = 1,730 × 1.55 ≈ 2,682 kcal/day
Frequently Asked Questions
What is Total Daily Energy Expenditure (TDEE)?+
TDEE represents the total number of calories your body burns in a 24-hour period, combining your Basal Metabolic Rate (BMR) with calories burned during physical activity and exercise.
How are activity multipliers calculated?+
Standard physical activity multipliers range from 1.2 (sedentary lifestyle) to 1.9 (heavy physical work or extreme training).
Are calorie targets exact prescriptions?+
No. Calorie calculations provide statistical estimates. Individual metabolic rates, body composition, and genetics vary.
