Body Fat Calculator

Know your body. Track your progress.

Body fat percentage is one of the best ways to understand your physique beyond the scale.

Using the trusted US Navy Method, this calculator estimates your body fat with reliable accuracy from simple circumference measurements — no expensive equipment or invasive tests needed.

Why This Exists:

• To help beginners get a clear baseline of their body composition.
• To give intermediates and advanced lifters a consistent way to track changes over time.
• To provide insight beyond weight, so you can make smarter training and nutrition decisions.

This isn’t guesswork or gimmicks — it’s real data you can act on. Combine it with your training and nutrition plan for the best results.
