Calorie Calculator

Calculate your daily calorie needs to maintain, lose, or gain weight based on your personal details and activity level.

Calculator implementation coming soon. This calculator is being developed and will be available shortly.

This calculator estimates your Total Daily Energy Expenditure (TDEE) using the Mifflin-St Jeor equation, considered the most accurate formula for most people.

How It Works

Mifflin-St Jeor Equation

TDEE = BMR × Activity Multiplier

Total Daily Energy Expenditure equals Basal Metabolic Rate multiplied by activity level.

BMR for men: (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5

BMR for women: (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161

TDEE is calculated by multiplying BMR by your activity level

Important Notes:

  • This calculator uses the Mifflin-St Jeor equation, considered most accurate for most people
  • Activity multipliers: Sedentary (1.2), Light (1.375), Moderate (1.55), Active (1.725), Very Active (1.9)
  • Individual variations in metabolism are not accounted for

Worked Example

A 30-year-old woman, 68 inches tall, weighing 150 pounds, with moderate activity.

Inputs:

  • gender:No
  • age:30
  • height:68
  • weight:150
  • activity Level:moderate

Result:

Her BMR is approximately 1,488 calories. With moderate activity, her TDEE is approximately 2,306 calories per day.

Who Is This Calculator For?

  • people tracking calories
  • weight loss goals
  • fitness enthusiasts

Frequently Asked Questions

BMR (Basal Metabolic Rate) is the number of calories your body needs at complete rest to maintain basic functions like breathing and circulation.
TDEE (Total Daily Energy Expenditure) is your BMR plus calories burned through physical activity. It represents your total daily calorie needs.
Eating 500 calories below your TDEE typically results in losing about 1 pound per week. A sustainable approach aims for 1-2 pounds of weight loss per week.
