Calculate your Body Mass Index (BMI), Basal Metabolic Rate (BMR), and Total Daily Energy Expenditure (TDEE). Get personalized health insights and ideal weight recommendations instantly.
To lose weight safely, aim for a calorie deficit of 500-750 calories per day.
To maintain your current weight, consume calories equal to your TDEE.
To gain weight healthily, aim for a calorie surplus of 300-500 calories per day.
Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. It's a useful screening tool but doesn't directly measure body fat percentage or account for muscle mass.
Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production while at rest.
Total Daily Energy Expenditure (TDEE) is the total number of calories you burn in a day, including your BMR plus calories burned through physical activity and digestion.
This BMI calculator is for informational and educational purposes only. BMI has limitations and may not be accurate for athletes, pregnant women, elderly individuals, or those with high muscle mass. This tool does not provide medical advice, diagnosis, or treatment. Always consult with qualified healthcare professionals for personalized medical advice and health assessments.
Our advanced BMI calculator is designed to provide comprehensive health insights beyond just your Body Mass Index. Simply enter your weight, height, age, gender, and activity level to get instant results including BMI, BMR, TDEE, ideal weight range, and personalized calorie recommendations for weight loss, maintenance, or gain.
Understanding your BMR and TDEE is crucial for effective weight management. BMR tells you the minimum calories your body needs to function, while TDEE accounts for your activity level. This information helps you create accurate calorie targets for your health goals, whether you want to lose weight, maintain, or build muscle.
While BMI is a useful screening tool, it has limitations. It doesn't distinguish between muscle and fat mass, doesn't account for bone density, and may not be accurate for athletes, bodybuilders, pregnant women, or elderly individuals. For a complete health assessment, consider additional metrics like body fat percentage, waist circumference, and waist-to-hip ratio.
