Body Fat Percentage Calculator

Find your body fat percentage and where it sits against healthy ranges for your sex.

Quick answer: Body fat percentage is your fat mass as a share of total weight. Fitness ranges are roughly 14–24% for men and 21–31% for women; athletic ranges are lower. Enter tape measurements to estimate yours.

Tape-based body fat estimates are typically accurate to within about 3–4 percentage points when measured carefully. Measure at the same time of day, keep the tape level and snug without compressing the skin. This is an estimate, not a medical assessment.

What is Body Fat Percentage Calculator?

This calculator focuses on the body fat percentage figure itself and how it compares with healthy ranges. Body fat percentage expresses fat mass relative to total body weight, so it answers a different question from BMI: not 'how heavy am I for my height' but 'how much of me is fat'. That distinction matters most for people with above-average muscle, where BMI misleads. Ranges differ by sex because women carry more essential fat for reproductive health. Use the same measurement technique each time so that the trend, rather than any single reading, tells the story.

Common Uses for Body Fat Percentage Calculator

  • Find your body fat percentage and healthy band
  • Compare men's and women's reference ranges
  • Track fat loss independently of scale weight
  • Set a body-composition target for a training block

Frequently Asked Questions

What is a good body fat percentage?
For general health, roughly 14–24% for men and 21–31% for women. Athletes often sit at 6–13% (men) and 14–20% (women). Below essential fat levels is unsafe and should be avoided.
Why do women have higher healthy body fat?
Essential fat is higher in women (about 10–13% versus 2–5%) because of reproductive physiology. Healthy ranges are therefore shifted upward by roughly 6–8 percentage points.
Can I target fat loss in one area?
No. Spot reduction does not work; fat is lost systemically. Where you lose it first is largely genetic. A calorie deficit plus resistance training preserves muscle while fat comes off overall.
