Examinations conducted in laboratory conditions, such as hydrostatic weighing and deuterium dilution, are more accurate and significantly more expensive. These methods are relatively easy and affordable, but not particularly reliable. In addition to the method provided by the calculators, skinfold measurement (pinch test) and electrical bioimpedance measurement can be used to measure fat percentage. The calculators provide you with a fat percentage estimate. The fat percentage calculation is based on a formula used by the United States army.

The fat percentage calculator based on measurements provides a more reliable estimate of your fat percentage. The first fat percentage calculator provides an estimate of your fat percentage based on statistics. Information About the Body Fat Percentage Calculator The ideal value for a normal fat percentage is about 15 percent for men, where the recommended range is between 13–18%, and about 22 percent for women. If muscle condition is poor, the BMI may indicate normal weight even when the fat percentage is higher than normal. For example, a bodybuilder's BMI may indicate that he/she is overweight although the fat percentage is low. The actual target weight may be different since lean body weight may increase (with exercise) or decrease (with diet or overtraining). It is somewhat better than BMI as an indicator for assessing weight, because BMI assumes that muscles are in average physical condition.

The fat percentage indicates the amount of fat in the total body weight as a percentage.
