RMR Calculator

Use this RMR calculator to estimate resting metabolic rate with the Revised Harris-Benedict equation from age, sex, height, and weight.

This RMR calculator provides a general estimate only and is not medical advice. Use it as an informational starting point, not as a diagnosis, treatment guide, or precise prescription for eating more or less. If you have a history of disordered eating, unexplained weight change, pregnancy, a metabolic or endocrine condition, or any reason to think your resting energy needs may be unusual, speak with a qualified healthcare professional before making health decisions based on the result.
