What is a Calorie Calculator?
A calorie calculator estimates the number of calories your body needs daily to maintain your current weight based on your age, gender, weight, height, and activity level. This is also known as your Total Daily Energy Expenditure (TDEE).
How to Use This Calculator
Enter your age, gender, weight, height, and select your activity level from sedentary to very active. The calculator will estimate your daily calorie needs for maintenance, weight loss, or weight gain.
Activity Level Guide
- Sedentary: Little or no exercise
- Lightly active: Light exercise 1-3 days/week
- Moderately active: Moderate exercise 3-5 days/week
- Very active: Hard exercise 6-7 days/week
- Extra active: Very hard exercise, physical job
Using Your Calorie Number
To lose weight, eat 250-500 calories below your maintenance level. To gain weight, eat 250-500 calories above. Aim for gradual changes of 1-2 lbs per week for sustainable results.
