How to use it

  1. Enter your sex, age, weight and height.
  2. Choose a formula. Mifflin-St Jeor is the most commonly used today.
  3. Read your BMR in kilocalories per day.

Examples

  • Female, 30, 65 kg, 165 cm → about 1,370 kcal/day (Mifflin-St Jeor).

BMR is an estimate of energy use at complete rest, not how much you should eat. Actual needs depend on activity; use the Calorie Calculator for that. Valid for ages 15 to 100. This is general information, not medical advice.
