TotalBody Fat Calculator
Body fat percentage tells you more than weight alone, because it separates fat from muscle and bone. Measure with a soft tape, relaxed, at the widest part of the waist.
How it works
This uses the US Navy circumference method, which estimates body fat from the ratio between your waist, neck and height. Women also need a hip measurement.
This is a general estimate for healthy adults, not medical advice. Formulas cannot account for body composition, medical conditions or medication. Talk to a doctor or dietitian before making significant changes.
