Calorie Calculator
Estimate daily calorie needs (BMR & TDEE).
About this tool
The Calorie Calculator estimates how many calories your body needs each day. It computes your BMR (Mifflin-St Jeor) and multiplies by an activity factor to give your TDEE, plus suggested targets for losing or gaining weight.
Frequently asked questions
BMR is the energy you burn at complete rest; TDEE adds your daily activity. TDEE is the figure to use for maintenance.
A deficit of about 500 calories/day tends to lose ~0.5 kg per week; a surplus does the reverse. These are estimates — adjust based on real results, and consult a professional for medical advice.
