BMR stands for Basal Metabolic Rate. It estimates how many calories the body may burn at rest before exercise or daily activity is included.

Is BMR the same as TDEE?

No. BMR estimates resting calorie needs, while TDEE estimates total daily calorie needs after activity level is included.

Which formula does this BMR calculator use?

This calculator uses the Mifflin-St Jeor equation, which estimates resting calories from age, height, weight and formula option.

Can I use BMR for weight loss planning?

BMR can be a useful starting point, but daily calorie planning usually needs TDEE because TDEE includes activity level and daily movement.
