Estimate Your Daily Calorie Needs for Weight Management

Understanding your daily calorie needs is the foundation of any successful weight management plan. This calculator uses the Mifflin-St Jeor equation, widely considered one of the most accurate methods, to estimate your Basal Metabolic Rate (BMR) and your Total Daily Energy Expenditure (TDEE).

How It Works

The calculation is a two-step process:

  • Basal Metabolic Rate (BMR): This is the number of calories your body needs to perform basic, life-sustaining functions at rest. The calculator uses your age, gender, height, and weight to determine this value.
  • Total Daily Energy Expenditure (TDEE): This is your total daily calorie need, which is calculated by multiplying your BMR by an activity level multiplier. The more active you are, the higher your TDEE will be.
  • Simply enter your details and select your activity level to receive a personalized estimate of the calories you need to maintain your current weight, as well as targets for mild and standard weight loss or gain.
