About This Calculator
This calorie calculator helps you determine your Basal Metabolic Rate (BMR) and daily calorie needs based on your age, height, weight, and activity level. Whether your goal is to lose weight, gain muscle, or maintain your current physique, understanding your calorie requirements is essential. Our tool is based on the Mifflin-St Jeor formula—considered one of the most accurate equations for calculating calorie expenditure.
Use the results to plan your diet and fitness goals effectively. For weight loss, aim for a 15% calorie deficit, and for weight gain, target a 15% surplus. Always consult a healthcare professional before making significant changes to your diet or exercise routine.
Learn More About BMR and Caloric Needs
Your BMR represents the number of calories your body needs to maintain basic functions like breathing, circulation, and cell production at rest. The activity multiplier adjusts this value to account for your lifestyle, from sedentary to very active. By understanding your maintenance calories, you can make informed decisions about your nutrition and fitness goals.
