The Calorie Needs Calculator is a powerful online application designed to help you know how many calories you need each day to maintain your weight. Whether it is weight loss, muscle building, or the maintenance of health, calorie needs in a day establish the very first phase of your own tailored program on nutrition and exercise.
Using the scientifically validated Mifflin-St Jeor equation, this calculator estimates your Basal Metabolic Rate (BMR)—the number of calories your body burns at rest—and then multiplies it by your selected activity level to determine your Total Daily Energy Expenditure (TDEE). The result is a highly accurate estimate of how many calories you need to consume daily to maintain your current weight.
What sets this calculator apart is its comprehensive input structure. It allows users to input their age, gender, weight, height, and choose between Metric (kg/cm) or Imperial (lbs/ft+in) units. Additionally, the activity level selector makes it suitable for both sedentary individuals and highly active users like athletes or physical laborers.

This feature makes the tool suitable not just for personal use, but also for trainers, dietitians, and healthcare professionals.
