What is BMR?
Basal Metabolic Rate is the number of calories your body needs just to keep functioning at complete rest — breathing, circulation, cell production. This calculator uses the Mifflin-St Jeor equation, widely considered more accurate than older formulas.
Formula (Mifflin-St Jeor)
Men: BMR = 10×weight(kg) + 6.25×height(cm) − 5×age + 5
Women: BMR = 10×weight(kg) + 6.25×height(cm) − 5×age − 161
Women: BMR = 10×weight(kg) + 6.25×height(cm) − 5×age − 161
