How to use the Calorie Calculator (BMR & TDEE)

Your BMR is the energy your body burns at complete rest. Multiplying by an activity factor estimates the calories you burn in a typical day. These are estimates — track your weight over a few weeks and adjust. Talk to a healthcare professional before making large dietary changes.

Formula

Mifflin-St Jeor: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + s, where s is +5 for men and −161 for women. TDEE = BMR × activity factor.
