Your Basal Metabolic Rate
BMR is the energy your body uses just to stay alive: breathing, circulating blood and keeping warm. Enter your age, height and weight to see it calculated with three formulas, and add body fat for the Katch-McArdle result.
What you can do
- Mifflin-St Jeor, Harris-Benedict (revised) and Katch-McArdle, compared with bars.
- Calories burned per hour at rest.
- A table of daily calories (TDEE) for all five activity levels.
Good to know
- Mifflin-St Jeor is generally the most accurate for the general population. Katch-McArdle suits people who know their body fat.
- BMR differs from person to person, so treat the result as an estimate.
- Your measurements are saved only in your browser so the other health calculators remember them, and are never sent anywhere.
