Body fat percentage calculator lets you estimate your body fat percentage quickly and accurately. It’s based on the Jackson & Pollock body density equations and only requires 4 measurements with a skinfold caliper, like this one.
This body fat calculator is a tool designed to help you estimate what percentage of your total body weight is body fat.
The composition of human body
More than 98% of the human body is composed of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Potassium, sulfur, sodium, chlorine, and magnesium are responsible for almost another 1%. These are the 11 most important, so called non-trace, elements. Regarding the molecules, the most common molecule in the human body is of course water, which takes about 65% of mass, followed by proteins and lipids. Other molecules which have a decent percent of mass are hydroxyapatite, carbohydrates and nucleic acids.
What is body fat?
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.

Is my body fat percentage normal?
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.
- Essential fat: 10–13% (women), 2–5% (men)
- Athletes: 14–20% (women), 6–13% (men)
- Fitness: 21–24% (women), 14-17% (men)
- Average: 25–31% (women), 18–24% (men)
- Obese: 32%+ (women), 25%+ (men)
This data means that if your body fat percentage is lower than 31% for women and 24% for men, you are in the average range and you have nothing to worry about. Higher levels of body fat may be dangerous for you.
Why should I control my body fat?
You need some body fat to regulate the production of hormones. An excessive percentage of body fat, however, can cause multiple health problems, such as:
- Heart diseases: obesity and high levels of body fat can lead to high blood pressure and high levels of bad cholesterol, which are also risk factors for heart diseases. In extreme cases, they can lead to strokes, the third most common cause of death in the United States.
- Male hormones problems: high body fat level in a woman’s body can lead to an excessive production of male hormones, causing facial hair growth and acne.
- Diabetes: high body fat can lead to type 2 diabetes. There’s a strong correlation between diabetes and being overweight; people most at risk for developing type 2 diabetes are those who have a high body mass index (BMI) and a high body fat percentage.
- Pregnancy complications: Women with high body fat levels are more likely to give birth prematurely or have children with health problems, including obesity. They are also more likely to need a Cesarean delivery.
