Calculate Your Resting Metabolic Rate

Calculate Your Resting Metabolic Rate

The calculators below estimate your Resting Metabolic Rate (RMR) using the Mifflin-St. Jeor equation  and your weight, height, and age. Choose the calculator that uses the units (e.g., pounds or kilograms) that you’re most familiar with, then input your values into the green cells.




The Mifflin-St. Jeor equations are perfect, but they have been shown to be the most accurate relative to other popular RMR formulas. (See, for example, Frankenfield, D. et al., “Comparison of Predictive Equations for Resting Metabolic Rate in Healthy Nonobese and Obese Adults: A Systematic Review,”
Journal of the Academy of Nutrition and Dietetics, Volume 105, Issue 5 (2005), pgs. 775–789.)
