Daily Calorie Needs Calculator (TDEE)
Your daily calorie needs combine your basal metabolic rate (BMR) with your daily activity level.
The Mifflin-St Jeor formula is widely regarded today as one of the more reliable formulas for estimating basal metabolic rate.
How Are Daily Calorie Needs Calculated?
Your daily calorie needs consist of two components: your basal metabolic rate (BMR) — the energy your body uses at complete rest to maintain basic life functions — plus your daily physical activity. This calculator uses the Mifflin-St Jeor equation, considered one of the more reliable formulas available today, to estimate your BMR, then multiplies it by a factor (between 1.2 and 1.9) matching your activity level to estimate your total daily energy expenditure (TDEE). This figure can vary from person to person depending on muscle mass, hormonal status, genetics and sleep quality. If you have a specific goal such as weight management, it's recommended to review this general reference together with a nutrition professional.
Frequently Asked Questions
What's the difference between BMR and TDEE?
BMR is the energy your body uses at complete rest; TDEE adds your daily activity and exercise on top of that to give your total calorie needs.
