TDEE Calculator
About the TDEE Calculator
Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a day, including rest, digestion, and physical activity combined.
Formula Used
How It Works
This calculator computes your BMR using the Mifflin-St Jeor equation, then multiplies it by an activity multiplier that reflects how much you move throughout the day.
Step by Step
- Calculate BMR using the Mifflin-St Jeor equation.
- Choose the activity multiplier matching your weekly exercise level.
- Multiply BMR by the multiplier to get your Total Daily Energy Expenditure.
Worked Example
Example: BMR of 1577.5 kcal, moderately active (×1.55):
TDEE = 1577.5 × 1.55 = 2445 kcal/day
Reference Table
| Activity Level | Multiplier |
|---|---|
| Sedentary | 1.2 |
| Light | 1.375 |
| Moderate | 1.55 |
| Active | 1.725 |
| Very Active | 1.9 |
Frequently Asked Questions
How is TDEE different from BMR?
BMR only measures calories burned at complete rest, while TDEE adds in calories burned through daily activity and exercise.
How do I use TDEE for weight loss?
Eating below your TDEE creates a calorie deficit needed for weight loss, while eating above it supports weight gain.
Should I recalculate TDEE as I lose weight?
Yes, TDEE changes as your weight changes, so it's a good idea to recalculate every few weeks during a weight loss or gain phase.
