What is BMR?
Basal Metabolic Rate is the number of calories your body needs to maintain basic functions — breathing, circulation, cell production — while completely at rest.
Formula used
This calculator uses the Mifflin-St Jeor equation, widely regarded as one of the most accurate BMR formulas for the general population.
Frequently asked questions
Is BMR the same as calories I should eat?
No — BMR is calories burned at complete rest. Your actual daily needs (TDEE) are higher once you factor in activity, which the Calorie Calculator accounts for.
