BMR Calculator

Estimate resting daily calorie burn with the Mifflin-St Jeor equation.

Basal Metabolic Rate is roughly how many calories your body burns at complete rest just keeping organs running. The Mifflin-St Jeor equation used here is the version most dietitians default to today.

Is BMR the same as calories I should eat?

No — BMR is rest-only burn. Multiply it by an activity factor (see the Calorie Needs calculator) to get a realistic daily target.
