BMI & Calorie Calculator
BMI category, BMR (Harris-Benedict) and daily calorie needs (TDEE)
Comprehensive Health Metrics
Our BMI and Calorie Calculator provides a comprehensive analysis of your physical profile by combining several key metrics. By inputting your height, weight, and gender, the tool calculates your Body Mass Index (BMI) to determine your health category. It also utilizes the Harris-Benedict formula to calculate your Basal Metabolic Rate (BMR), which represents the energy your body requires at rest. This provides a solid foundation for understanding your unique metabolic needs.
Personalized Calorie Goals
The tool goes beyond basic metrics by calculating your Total Daily Energy Expenditure (TDEE) based on your specific activity level. Whether you have a sedentary lifestyle or are extremely active, the calculator adjusts your daily calorie needs accordingly. Furthermore, it provides clear targets for weight management, showing you exactly how many calories to consume if you want to lose weight or gain weight by a target of 500 calories per day.
Frequently asked questions
What is BMI?
Body Mass Index (BMI) is a standard measure used to determine if your weight is healthy relative to your height. The tool categorizes results into groups such as underweight, normal weight, overweight, or obesity, helping you understand where you stand on the health spectrum based on your specific measurements.
How are my daily calories calculated?
The calculator uses the Harris-Benedict formula to determine your Basal Metabolic Rate (BMR), which is the energy needed at rest. It then factors in your activity level—ranging from sedentary to extremely active—to calculate your Total Daily Energy Expenditure (TDEE), providing a personalized estimate of calories burned daily.
How many calories should I eat to lose weight?
To lose weight, it is common to aim for a deficit of 500 calories below your TDEE. The tool calculates this specifically for you based on your profile and activity level, providing a clear target to help you manage your daily intake effectively for sustainable weight loss.
What are the different activity levels?
The tool includes various activity levels to ensure accuracy. These range from 'Very little movement' for desk-based roles to 'Moderately active' and 'Very active' for regular exercise, up to 'Extremely active' for those performing intense physical labor or training twice daily.
