Body Fat Calculator

Estimate your body fat percentage using the U.S. Navy method.

Weight alone doesn't tell the whole story of health. Two people can weigh the same, but one might have a high muscle mass while the other has a high body fat percentage. Understanding your body composition—the ratio of fat to lean mass—is a much better indicator of fitness and disease risk. While professional methods like DEXA scans are expensive, the U.S. Navy Body Fat formula provides a highly consistent estimate using just a tape measure. Our Body Fat Calculator uses this proven method to help you track your progress beyond the scale.

Hoe het werkt

The calculator uses a logarithmic formula that compares your height to the circumference of your neck and waist (and hips for women). These specific measurements correlate strongly with abdominal and visceral fat levels.
