Calorie Calculator
About Calorie Calculator
The Calorie Calculator helps you estimate how many calories you need per day to maintain, lose, or gain weight. It uses your age, gender, weight, height, and activity level to calculate your daily energy needs accurately.
Formula (Simple Explanation)›
TDEE = BMR × Activity Factor
BMR (Basal Metabolic Rate) represents the calories burned at rest. The Activity Factor adjusts it based on your lifestyle — sedentary, light, moderate, or active.
Example:
Input: A 30-year-old woman weighing 60 kg, height 165 cm, with moderate activity level
Output: Daily calorie requirement ≈ 2,000 calories to maintain weight.
Steps to Use:
- Select your gender.
- Enter your age, height, and weight.
- Choose your daily activity level (sedentary to very active).
- Click 'Calculate' to view your daily calorie requirement for maintenance, weight loss, or gain.
Frequently Asked Questions
What does the Calorie Calculator do?›
It estimates your Total Daily Energy Expenditure (TDEE) — the total number of calories you burn in a day based on your metabolism and activity level.
How is this calculator different from the BMR calculator?›
BMR shows the calories your body burns at rest, while the Calorie Calculator adds your activity level to estimate total daily calorie needs.
What is a calorie deficit?›
A calorie deficit happens when you consume fewer calories than you burn. It’s essential for healthy weight loss.
How accurate is this calorie calculator?›
It provides a close estimate using scientifically validated equations like Harris-Benedict or Mifflin-St Jeor. Results may vary slightly by individual metabolism.
Can this calculator help me gain weight?›
Yes. To gain weight, consume 300–500 calories more than your maintenance calories calculated here.
