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.
