BMR Calculator

Estimate how many calories your body burns at rest to support essential functions.

What is BMR?

BMR stands for Basal Metabolic Rate. It estimates the calories your body would use over 24 hours at rest, just to keep you alive and functioning.

Your BMR covers essential processes such as breathing, circulation, organ function, and temperature regulation. It does not include normal daily movement or training.

BMR is a foundation for broader calorie estimates like TDEE, but on its own it should not be treated as a full daily calorie target.
