Try it nowBody fat percentage is the proportion of your body weight that consists of fat tissue.
Maintaining healthy body fat levels can improve cardiovascular health, boost energy, and enhance overall well-being.
For best results, measure in the morning before eating and use a flexible measuring tape.
This calculator uses the U.S. Navy circumference method, which estimates body fat from your height plus neck, waist, and (for women) hip measurements.
For men, roughly 10–20% is considered healthy, and for women roughly 18–28%. Athletes are often lower. Essential fat is about 3–5% for men and 10–13% for women.
The Navy method is typically within 3–4% of a DEXA scan when measurements are taken carefully, making it a practical, no-equipment estimate for tracking trends over time.
