Navy Body Fat Formula

For Men:


Body Fat % = 86.010 × log10(abdomen - neck) - 70.041 × log10(height) + 36.76

For Women:


Body Fat % = 163.205 × log10(waist + hip - neck) - 97.684 × log10(height) - 78.387

Example Calculation

Let's calculate body fat percentage for a male with the following measurements:

Height: 70 inches
Neck: 15 inches
Waist: 34 inches

Using the formula for men:

Body Fat % = 86.010 × log10(34 - 15) - 70.041 × log10(70) + 36.76
Body Fat % = 86.010 × log10(19) - 70.041 × log10(70) + 36.76
Body Fat % = 86.010 × 1.2788 - 70.041 × 1.8451 + 36.76
Body Fat % = 110.0 - 129.2 + 36.76 = 17.56%

This individual has a body fat percentage of 17.56%, which falls within the "Fitness" category for men according to Navy standards.

Frequently Asked Questions

How accurate is the Navy body fat method?

The Navy body fat method is considered reasonably accurate for population-level assessments, with studies showing correlations of 0.7-0.9 with more precise methods like DEXA scans. However, individual results may vary based on factors like body type, age, and fitness level. It's most useful for tracking changes over time rather than obtaining absolute values.

Why does the formula differ for men and women?

Men and women store fat differently due to hormonal differences. Women typically store more fat in the hip and thigh area (gynoid pattern), while men tend to store more abdominal fat (android pattern). The Navy formulas account for these different fat distribution patterns to provide accurate estimates for both genders.

What are the Navy body fat standards?

For men aged 17-39, the maximum allowable body fat is 22%; for ages 40+, it's 24%. For women aged 17-39, the maximum is 33%; for ages 40+, it's 34%. These standards ensure military personnel maintain the physical readiness required for their duties. Our calculator shows how your results compare to these standards.

How often should I measure my body fat?

For tracking progress, measure every 4-8 weeks. More frequent measurements may not show meaningful changes and can be discouraging. Always measure at the same time of day under similar conditions (preferably in the morning before eating or drinking) for consistency.

Can I use this calculator if I'm not in the military?

Absolutely! While developed for military use, the Navy body fat calculator is widely used by civilians for its practicality and reasonable accuracy. It's an excellent tool for anyone wanting to track body composition changes without specialized equipment.
