Health Calculators/BMR Calculator

BMR Calculator

Find your Basal Metabolic Rate: the calories your body burns at complete rest.

BMR Calculator

Understanding BMR

What BMR covers

  • Breathing and circulation
  • Keeping your body temperature steady
  • Brain and nervous system activity
  • Building and repairing cells

What moves your BMR

  • Muscle: more muscle burns more at rest
  • Age: BMR slowly declines over the years
  • Size: taller and heavier bodies burn more
  • Crash diets: very low intakes can lower it over time

BMR vs TDEE

BMR is only your resting burn. Multiply it by your activity level, or use the TDEE calculator, to get the calories you need each day.

Good to know

Mifflin-St Jeor is the most reliable everyday equation for adults, but individual metabolisms vary.
