Body Fat Calculator

This calculator estimates body fat percentage using common measurement-based methods. Body fat percentage gives a better idea of body composition than weight or BMI alone.

Common Methods

Popular equations include the U.S. Navy method and various skinfold formulas. The Navy method typically uses:

  • Men: height, neck, and waist circumference
  • Women: height, neck, waist, and hip circumference

Example (Conceptual)

A higher waist measurement relative to height and neck generally increases the estimated body fat percentage. Results should be treated as estimates because measurement technique strongly affects accuracy.

Important Notes

  • Results vary between different formulas.
  • Tape measurement position and tension must be consistent.
  • This is not a medical diagnosis tool.
