What is BMR?
Calculate BMR (Basal Metabolic Rate) to understand your body's minimum energy requirements at rest. Knowing your BMR helps in weight management, diet planning, and fitness goals. Our BMR calculator uses the Mifflin-St Jeor equation for accurate results. Discover how many calories your body needs daily to maintain basic functions like breathing and circulation.

BMR: calories/day
Daily Calorie Needs: calories/day
BMR Calculation Formula
The Mifflin-St Jeor equation used to calculate BMR:
Men: (10 × weight) + (6.25 × height) - (5 × age) + 5
Women: (10 × weight) + (6.25 × height) - (5 × age) - 161

BMR Calculator FAQs
1. What's the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is your resting calorie needs, while TDEE (Total Daily Energy Expenditure) includes physical activity. Our calculator shows both metrics for complete energy expenditure understanding.
2. How accurate is this BMR calculator?
Our calculator uses the clinically validated Mifflin-St Jeor equation, providing 90-95% accuracy for most adults. Individual variations may occur based on muscle mass and health conditions.
