This tool calculates your total daily calorie needs based on your height, weight, age, gender, and activity level.
How to Use This TMI Calorie Calculator
This tool helps you estimate the number of calories you need to maintain your current weight based on your age, gender, weight, height, and activity level.
- Age: Enter your age in years.
- Gender: Select your gender from the dropdown.
- Weight: Enter your weight in kilograms.
- Height: Enter your height in centimeters.
- Activity Level: Select your daily activity level from the dropdown.
- Press the “Calculate” button to see your estimated daily calorie needs.
How It Calculates the Results
The calculation uses the Mifflin-St Jeor Equation which is a widely-accepted formula to estimate Basal Metabolic Rate (BMR), then multiplies the BMR with the Activity Factor to estimate Total Daily Energy Expenditure (TDEE).
BMR for men: (10 * weight) + (6.25 * height) – (5 * age) + 5
BMR for women: (10 * weight) + (6.25 * height) – (5 * age) – 161
TDEE: BMR * Activity Level
Limitations
This calculator provides an estimate and may not be accurate for all individuals. Factors such as muscle mass, hormonal imbalances, and metabolic adaptations can affect actual calorie needs. It’s recommended to use this tool as a general guide and consult a healthcare provider for personalized advice.
