BMR-Calorie Calculator: What are Your Daily Calorie Needs?

Your metabolism plays a major role in how quickly you burn calories. Your BMR (Basal Metabolic Rate) is the number of calories burned when completely at rest.

Using your BMR as a starting point, you can learn how many calories your body will burn at your activity level. Learn more with this BMR and calorie calculator.

Quick Facts About the Basal Metabolic Rate:
  • The BMR is also commonly refered to as RMR, for Resting Metabolic Rate.
  • It's never a good idea to cut your calorie intake below your BMR. This puts your body in "starvation mode", where your body slows your metabolism down to conserve energy. This is a common mistake among dieters.
  • Your BMR depends on many physical factors, such as your weight, gender, age, and height.
  • As you lose weight, your BMR will decrease, because the body needs less fuel (calories) to survive.
  • This tool uses the popular Harris-Benedict equation to calculate your BMR (calories burned at rest).
