How the Calorie Calculator Works
This calculator estimates how many calories you may need per day to maintain your current weight. It uses your basic body information and activity level to estimate your daily calorie needs.
Daily Calories = BMR × Activity Level
Example
A person with a daily maintenance need of 2,400 calories may need around 1,900 calories for weight loss or around 2,900 calories for weight gain.
Weight gain: maintenance + 500 calories
This tool gives an estimate only. Real calorie needs can vary depending on metabolism, muscle mass, health condition and lifestyle.
