How This Calorie Calculator Works
This calculator uses a common BMR equation and your selected activity level to estimate how many calories you burn each day. It then adjusts that number based on your goal.
Why Daily Calories Matter
Daily calorie intake affects your body weight, energy levels, and nutrition plan. Eating fewer calories than you burn may help with weight loss, while eating more may support weight gain.
Calories for Weight Loss, Maintenance, and Gain
Maintenance calories are the estimated number of calories needed to keep your current weight. For weight loss, calorie intake is usually lower than maintenance. For weight gain, it is usually higher.
