Tape-test-style body fat estimate, checked against typical age-banded maximum standards.
Standards table is a commonly-cited approximation — always check the current official regulation for the exact, up-to-date limits.
No — it uses the same US Navy circumference formula as the main Body Fat Calculator, checked against commonly-cited age-banded maximum allowances. Always check the current official regulation for the exact, up-to-date limits.
The maximum allowed body fat percentage is looked up from your age bracket (e.g. under 20, 21–27, 28–39, 40+) and sex, using typical published limits — men's limits are lower than women's at each age band.
It's the difference between the age band's maximum allowed body fat % and your estimated body fat % — a positive margin means you're under the limit, and the label switches to 'Over limit by' once your estimate exceeds it.
