What is Calorie Calculator?
The Calorie Calculator helps determine Total Daily Energy Expenditure (TDEE) and daily calorie needs based on your basal metabolic rate and activity level.
Calorie Calculation Methods
Harris-Benedict Equation
BMR × Activity Factor = Daily Calories
Mifflin-St Jeor Equation
TDEE = BMR × Activity Level

Frequently Asked Questions
How many calories should I eat to lose weight?
Create a 500-1,000 calorie deficit below your maintenance level. For example, if maintenance is 2,500 calories, eat 1,500-2,000 calories for weight loss.
What is TDEE?
Total Daily Energy Expenditure (TDEE) is the total calories you burn in a day, including basal metabolic rate and all activities.
How accurate are calorie calculators?
Calorie calculators are approximately 90% accurate for most people. Individual variations exist based on metabolism, body composition, and other factors.
