Navy Body Fat formulas

Imperial Units

for man: % Body Fat = 86.01 x log10 (waist - neck) - 70.041 x log10 (height) + 36.76

for women: % Body Fat = 163.205 x log10 (waist + hip - neck) - 97.684 x log10 (height) - 78.387

Height - height in inches, waist - waist circumference in inches, neck - neck circumference in inches, hip - circumference of the women hips at the largest horizontal measure in inches.

Metric Units

for man: % Body Fat = 495/(1.0324-0.19077(log10(waist-neck))+0.15456(log10(height)))-450

for women: % Body Fat = 495/(1.29579-0.35004(log10(waist+hip-neck))+0.221(log10(height)))-450

Height - height in centimeters, waist - waist circumference in centimeters, neck - neck circumference in centimeters, hip - circumference of the women hips at the largest horizontal measure in centimeters.

Calculating Navy Body Fat Percentage

Let's calculate the body fat percentage using the U.S. Navy Method for a 28-year-old man:

Height: 6 feet (72 in)

Waist circumference: 34 inches

Neck circumference: 16 inches

U.S. Navy Method:

Body Fat (%) = (86.01 × log10(34 - 16)) - (70.041 × log10(72)) + 36.76 ≈ 14.6% (check with the calculator )

Navy	Male	22	22	22	23
	Female	33	33	33	34
Marine Corps	Male	18	18	18	18
	Female	26	26	26	26
Air Force	Male	20 (17–29 y)		24 (30+ y)
	Female	28 (17–29 y)		32 (30+ y)

FAQ

✅ What is the Navy Body Fat Calculator used for?

The Navy Body Fat Calculator is a tool used to estimate an individual's body fat percentage based on specific measurements and formulas developed by the U.S. Navy. It helps determine if potential recruits and active-duty personnel meet the Navy's body composition standards.

✅ How does the Navy calculate body fat percentage?

The Navy utilizes circumference-based methods rather than just height and weight. For men, it measures neck and waist circumferences. For women, it's neck, waist, and hips. These measurements get plugged into Navy-derived equations to estimate body fat.

✅ Why does the Navy use a specialized body fat formula?

The Navy aims for calculation methods that reliably predict body fat across a wide range of age, gender, ethnicity and fitness levels. Their formulas were developed using data from thousands of Navy members to increase accuracy for a military population.

✅ Do I need any special equipment to use the Navy calculator?

You'll need a flexible tape measure to get your circumference measurements. Make sure to follow the Navy's specific instructions for measuring locations to get precise numbers. A small error can significantly impact the body fat estimate.

✅ What body fat percentage does the Navy consider acceptable?

The allowable ranges vary by age and gender, but generally the Navy wants men under 26% body fat and women under 36% body fat. However, limits increase slightly for personnel over age 40.

✅ I got my body fat percentage - what's next?

If your result puts you within the Navy's acceptable limits for your age and gender, great! If not, you may need to adjust your diet, increase exercise, or potentially seek other methods like water weight-loss to meet the standards.

✅ Is the Navy calculator accurate for civilians too?

While designed for a military population, the circumference-based Navy calculations can provide reasonably accurate body fat estimates for non-military individuals as well compared to other techniques. Just be sure to follow the measurement protocol closely.

✅ Will being very muscular skew my Navy body fat results?

Possibly. The equations don't inherently distinguish between fat and lean muscle mass. If you're an outlier in terms of extreme muscularity, the Navy calculator could overestimate your true body fat percentage simply due to your larger circumferences.

✅ How does the Navy body fat test compare to other methods?

The circumference-based approach is considered more accurate than simple height/weight formulas but not as precise as techniques like DEXA scans or hydrostatic weighing. Its affordability and ease of use make it valuable for military-wide screening purposes.

✅ Do any special situations affect using the calculator?

Yes, the Navy has different policies regarding body composition evaluations during pregnancy, within 9 months postpartum, and for certain medical conditions. Consult the official instructions if any of those scenarios apply.

The Navy Body Fat Calculator can serve as a good initial screener of overall body composition, whether you're enlisting or just a fitness buff. While no formula is perfect, following the Navy's standardized protocols should give you a reasonable estimate compared to other basic methods.
