About This Tool
The Calorie Calculator estimates your Total Daily Energy Expenditure (TDEE) — the number of calories your body needs each day based on age, weight, height, sex and activity level.
Frequently Asked Questions
What formula does this calculator use?
This calculator uses the Mifflin-St Jeor equation, currently considered the most accurate BMR formula for most adults.
What is BMR vs TDEE?
BMR (Basal Metabolic Rate) is the calories burned at complete rest. TDEE (Total Daily Energy Expenditure) adds calories burned through daily activity.
How many calories should I eat to lose weight?
A common guideline is to eat 500 calories below TDEE per day to lose approximately 0.5 kg (1 lb) per week, though individual results vary.
