What is a body fat calculator?
Body fat percentage is the proportion of body weight that is made up of fat. Measuring body fat percentage is important because even if your BMI is normal, you can still have 'skinny fat,' a condition where body fat is high.
BMI-based body fat percentage formula (Deurenberg formula)
Body Fat Percentage (%) = 1.2 × BMI + 0.23 × Age − 10.8 × Gender (Male: 1, Female: 0) − 5.4

Frequently Asked Questions
What is a healthy body fat percentage?
14–241 TP3T for men and 21–311 TP3T for women are generally classified as the healthy range. Athletes may have lower values than this.
What is the difference between body fat percentage and BMI?
BMI is calculated based solely on height and weight and does not reflect muscle mass. Body fat percentage measures the actual proportion of fat, allowing for a more accurate identification of conditions such as "skinny fat.".
What should I do to reduce body fat?
It is effective to combine aerobic and strength training and maintain a calorie deficit. If you consume sufficient protein, you can reduce body fat without losing muscle.
