About the Calorie Calculator
Estimate how many calories you burn per day, free. This calorie calculator uses the research-backed Mifflin-St Jeor equation to compute your BMR (basal metabolic rate), then multiplies by your activity level to get your TDEE — the maintenance calories that keep your weight steady. You'll also see suggested targets for losing or gaining roughly 0.5 kg (1 lb) per week. Pair it with the BMI calculator to set realistic goals.

Frequently asked questions
What is TDEE?
Total Daily Energy Expenditure — the calories you burn per day including activity. Eat at TDEE to maintain weight.
How do I lose or gain weight?
A deficit of ~500 kcal/day typically loses about 0.5 kg (1 lb) per week; a surplus does the reverse.
What's the difference between BMR and TDEE?
BMR is what you'd burn at complete rest; TDEE adds daily activity and exercise. Eat around TDEE to maintain, below it to lose.
