Daily calorie estimate
This calculator estimates calorie needs using BMR and an activity multiplier. It gives simple targets for maintenance, weight loss and weight gain.
Formula used
Maintenance calories = BMR x activity factor. Weight loss estimate = maintenance - 500 calories. Weight gain estimate = maintenance + 500 calories.
Important note
Calorie needs vary by lifestyle, body composition and health status. Use this as a planning estimate, not medical advice.
