Understand Your Daily Calorie Needs with WellCal

The Calorie Calculator by WellCal helps you discover exactly how many calories your body needs each day to maintain, lose, or gain weight. Whether your goal is to stay fit, lose fat, or build muscle, this smart tool provides accurate, science-backed calorie insights based on your body composition, activity level, and lifestyle.

How the Calorie Calculator Works

The WellCal Calorie Calculator uses the Mifflin-St Jeor equation — a trusted formula used by nutritionists worldwide. By entering your age, gender, height, weight, and activity level, the calculator estimates your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE).
Your BMR represents how many calories your body burns at rest, while your TDEE reflects how much energy you burn throughout the day, including exercise and movement.

Once you know your daily calorie needs, you can set realistic nutrition goals — whether that’s eating fewer calories for weight loss or increasing intake to support muscle growth.

How to Use the Calorie Calculator

  1. Enter your age, gender, weight, and height.

  2. Select your activity level (sedentary, moderate, or active).

  3. Click “Calculate” to see your personalized daily calorie target.

  4. Use the results to plan meals and track your health journey.

This tool helps you make smarter eating decisions and build long-term healthy habits. Combine it with WellCal’s BMI and Macro Calculators for a complete wellness experience.
