Body Fat Calculator

Want to know your body fat percentage? This calculator uses the U.S. Navy method, which is a quick way to estimate body fat using a tape measure and a few stats. It’s not as precise as a DEXA scan, but it’s a solid ballpark for most people.

How does the U.S. Navy method work?

The U.S. Navy body fat formula uses your height, neck, and waist measurements (plus hips for women) to estimate your body fat percentage. It’s not perfect, but it’s a lot more accessible than a DEXA scan or hydrostatic weighing. For more on the method, check out the official Navy calculator.

Healthy body fat ranges vary by age and gender. The American Council on Exercise (ACE) recommends 6-24% for men and 16-31% for women, but athletes and older adults may fall outside these ranges.

Remember, body fat percentage is just one piece of the health puzzle. For a full picture, consider talking to a healthcare provider or registered dietitian.
