Calorie Calculator

The Calorie Calculator estimates your daily calorie needs for free based on your details and activity level, so you can plan eating for maintaining, losing or gaining weight.

How daily calorie needs are estimated

Your daily calorie target is based on your basal metabolic rate (the energy your body uses at rest) multiplied by an activity factor, then adjusted for your goal. It is a starting estimate — real needs vary, so track results and adjust over time.

2. Select your activity level and goal.
