BMI Calculator (Body Mass Index)

A formula that uses weight and height to estimate body fat and gauge health risks due to carrying too much weight. The BMI is only one factor in determining a person's health risk. A BMI in the "healthy" range does not necessarily mean that you are fit and healthy!

BMI does not take into account lean body mass or body frame. A muscular, large-framed person's BMI could indicate obesity, but other indicators would show that this is not the case.

Note: not a good indicator for those who are under 18, very muscular, large-framed or pregnant.

Your BMI is:
  • BMI less than 18.5 = underweight *
  • BMI 18.5 to 24.9 = healthy
  • BMI 25.0 to less than 29.9 = overweight
  • BMI 30.0 or greater = obese

* Note: there is some controversy regarding the under- weight indicator. Studies show that a low BMI is considered a risk factor. However, by eliminating those in the studies who are underweight due to a fatal disease, chronic illness and such, there are indications that a low BMI is not necessarily a risk factor if you are otherwise fit and healthy.
