Body Fat Percentage Calculator

Body fat vs BMI

BMI uses only height and weight, so it cannot distinguish muscle from fat. Body fat percentage targets the thing that actually matters for many health goals. Estimation methods range from tape-measure formulas to scales and DEXA scans; simple estimates are convenient but less precise than clinical measurement.

Frequently asked questions

What is a healthy body fat percentage?

Roughly 14–24% for men and 21–31% for women is typical for general fitness, though ranges vary by age and goals.

Why is body fat better than BMI?

Because two people with the same BMI can have very different amounts of fat and muscle. Body fat percentage measures composition, not just weight.

How accurate are body fat estimates?

Tape-measure and formula-based estimates are convenient but can be off by several points. For precision, methods like DEXA scans are more reliable.
