How this calculator works

We estimate your basal metabolic rate (BMR) using a standard formula based on age, height, weight and sex. We then apply an activity multiplier to estimate daily calories for maintenance at your selected activity level.

This is a general estimate. Individual calorie needs vary due to factors such as body composition, metabolism and lifestyle.
