What is Body Fat Calculator?

▾

A body fat percentage calculator estimates fat mass as a proportion of total body weight using skinfold measurements, circumference methods (US Navy), or BMI-derived formulas.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

Frequently Asked Questions

▾
Q

What's a healthy body fat percentage?

A

Athletes: 6-13% (male), 14-20% (female). Fitness: 14-17% (male), 21-24% (female). Varies by age and sport.

Q

Is BMI the same as body fat %?

A

No. BMI = weight/height² and doesn't distinguish muscle from fat. Body fat % is more accurate for health.

Q

How accurate is the Navy method?

A

Accurate within ±2-3%. DEXA scan (clinical) is more precise but requires equipment and cost.
