MyFatCalc

MyFatCalc is a free online body fat calculator that puts several established estimation methods in one place: CUN-BAE, the U.S. Navy method, BMI-based estimation, and skinfold approaches, depending on which measurements you have. Enter the relevant age, sex, height, weight, circumference, or skinfold values, and review an estimated body fat percentage together with related figures such as lean mass and a goal-weight reference. Seeing multiple methods in one comparison view makes the point that body fat calculations are estimates and that results vary with the formula and the measurements used. The site is meant for personal education, fitness tracking, and general planning rather than diagnosis or medical treatment. There is nothing to install and no account to create, and method-specific guidance keeps each input clear.
