Body Fat Calculator

Your body weight consists of lean muscle mass, fat, organs, bones, and fluids. When we talk about “losing weight,” it’s really only fat we want to lose (though many people end up losing lots of lean muscle mass and water weight. Because whether your main concern is health or looking fabulous in a bathing suit, your body composition–specifically the amount of fat you’re carrying–is more important than your overall body weight. This calculator will help you estimate your body fat percentage.

How Much Body Fat Is Healthy?

So how low is low enough? Purely from a health perspective, anything under 30% body fat for women and 25% body fat for men is considered acceptable. However, women should aim for less than 25% body fat and men for less than 20%. If your goal is to look toned and sculpted with some abdominal definition, you’ll need to drop even lower: under 20% for most women and under 14% for most men. Going for a totally chiseled six-pack? Most guys will need to get down to around 8% body fat to achieve that look, while most women need to drop to around 15%. By the way, top male bodybuilders compete at 3-6% body fat and top female bodybuilders and fitness models compete at 8-12%. Note, however, that body fat levels this low aren’t sustainable year round, and women will generally stop menstruating at or near competition weight.

Limitations

Our Body Fat calculator will provide the most accurate results for individuals with average body composition who are neither excessively overweight nor excessively underweight. If you are obese, super skinny, or an athlete/bodybuilder with very low body fat, your results will likely be off. Additionally, the girth measurements utilized by the calculator are less accurate than several other body fat measurement techniques. Leading the pack in accuracy are dual energy X-ray absorptiometry (DXA) and hydrostatic (underwater) weighing. Unfortunately these methods are not easily accessible. The most accurate body fat measurement devices you can use at home are skinfold calibers and bioelectrical impedance analysis (BIA) scales.
