If you ever wondered what is your body fat percentage, this is a perfect place to find out.

It is actually adipose tissue; its main function is to store energy in the form of lipids, but it cushions and insulates your body, too. Your body stores two types of fat: essential and storage body fat. The former is necessary to support life and reproductive functions. Essential body fat is substantially higher for women because of childbearing and hormonal functions. Storage body fat is the mass of additional accumulated fat. It does not mean that this type of body fat is unnecessary, though - part of it protects your abdomen and internal organs.
You can estimate your body fat with our body fat percentage calculator. Remember that no calculator, however complicated, can replace a visit in a doctor's office. You should treat this result as a rough estimate; it can only tell you if your body fat percentage is drastically too high, but there's no reason to panic if the result differs just slightly from the recommended value.
To calculate the body fat percentage, you need to take the following measurements:
Once you have taken all of the measurements, you can input them all into the body fat calculator. If you are interested how it works, there are the formulas we use:
lean body mass (men) = (weight * 1.082) + 94.42 - Waist * 4.15
lean body mass (women) = (weight * 0.732) + 8.987 + wrist / 3.140 - waist * 0.157 - hip * 0.249 + forearm * 0.434
body fat weight = weight - lean body mass
body fat percentage (BFP) = body fat weight / weight
Both equations for lean body mass use weight in pounds and all other measurements in inches. If you are using other units, you need to transform the formulas accordingly.
Once you calculated your body fat percentage, you should compare it with the recommended values. The list below comes from the American Council on Exercise and shows the average percentages in specified groups.
