About This Calculator
This TDEE Calculator estimates your Total Daily Energy Expenditure, which is the number of calories your body burns each day through metabolism and physical activity. It uses the Mifflin-St Jeor formula to calculate your Basal Metabolic Rate (BMR), then multiplies it by your selected activity level.
BMR for women = 10 × weight (kg) + 6.25 × height (cm) − 5 × age − 161
TDEE = BMR × Activity Level
How to Use
- Enter your gender, age, height, and weight.
- Select your typical activity level.
- The calculator will show your estimated TDEE in kcal per day.
The result helps you understand how many calories your body needs to support your current routine without weight gain or loss.
