Army Body Fat Calculator: Check Body Fat %

The Army Body Fat Calculator is an online tool that allows you to see an estimate of your body fat percentage using the measurement criteria set by the United States Army. This can help current service members, those wishing to join the military, National Guard members and those wishing to prepare for military fitness tests.

The United States Army have certain requirements regarding the body composition of their service members. While body weight is measured to help determine if someone is fit for service, it often isn’t enough to give a full view of someone’s physical make-up. Two people can be the same height and weight but still have very different body compositions.

The Army Body Fat Calculator can give an estimate of your body composition. This can be calculated using your height, neck measurements, waist measurements and hip measurements (if required). This can vary depending on the calculation method and your gender.
This calculator can be very beneficial for many.

Enter a few body measurements to get an estimate of your body fat percentage. This can then be compared to the required requirements set by the United States Army.

Please note this is for informative purposes only. Any official Army calculations must be done using the current guidelines set out by the Department of the Army.

Army Body Fat Calculator Formula

The United States Army have used a number of methods to calculate body fat using circumferences. This will involve measuring your height and body.

One popular method is the following:

Using Circumference Measurements

Many online military body fat calculators use the traditional US navy method. Please remember this is just an estimate.

Male Body Fat Formula

One popular formula for males is:

BF% = 86.010 Log10 (Waist – Neck) -70.041 Log10(Height) +36.76

All measurements must be in Inches.

Where:

BF% – Estimated body fat percentage

Waist – Stomach circumference (inches)

Neck – Neck circumference (inches)

Height – Height (inches)

Log10 – Log base 10.

Female Body Fat Formula

One popular formula for females is:

BF% = 163.205 Log10 (Waist + Hip – Neck) -97.684 Log10(Height) -78.387

All measurements must be in Inches.

Where:

BF% – Estimated body fat percentage

Waist – Waist circumference (inches)

Hip – Hip circumference (inches)

Neck – Neck circumference (inches)

Height – Height (inches)

Please note these are popular formulas to estimate body fat using circumferences. These should not be used as a replacement for the current Army approved body fat calculation. Always refer to the official Army guidelines.

Example Calculation

Let’s look at an example.

A male military applicant provides the following measurements.

Measurement Value

Height 70 Inches

Waist 34 Inches

Neck 16 Inches

Age 28 Years

We can plug these into the male formula:

BF% = 86.010 Log10 (34 – 16) -70.041 Log10(70) +36.76

Calculate the Waist – Neck:
34-16=18

Now we can plug our numbers in:

BF% = 86.010 Log10 (18) -70.041 Log10(70) +36.76

This gives us an estimated body fat percentage of:
18.9%

This means they have an estimated body fat of 18.9% of their total body weight.

This is just an example of a popular circumference formula. This is not an official Army assessment.

Understanding Your Army Body Fat Calculator Results

Once you’ve entered your measurements, you’ll see an estimated body fat percentage.

This can help you understand your body composition.

Your body fat percentage shows:

An estimate of how much fat you have as a percentage of your total body weight.

If you have an estimated body fat of 20%, this means you have approximately 20% of your total body weight as fat. The remainder will be made up of muscle, bones, organs, water and other tissues.

Army Body Fat Requirements – The Army have certain maximum body fat requirements. This can vary depending on the policy, age and gender. It’s important to meet the correct requirements.

Tracking Fitness – If you regularly calculate your body fat percentage you’ll be able to see any changes and see if your fitness routine is working.

Having a low body fat percentage doesn’t necessarily mean you’ll perform better in the military. Strength, stamina, mobility, recovery and overall fitness are all important.

What Affects Your Results?

There are many things that can affect your estimated body fat percentage.

• Incorrect Measurements – Getting incorrect measurements for your waist, neck and/or hip will greatly affect your results. Small differences can create different percentages.
• Muscle – If you have a high amount of muscle, your body composition may be different even though you have similar height and weight.
• Fat Distribution – Some people naturally have more fat around their stomach. Others will have more around their hips and thighs. The formulas will use these measurements to calculate your body fat.
• Age – As you age your body composition can change. You may have different muscle levels, fat distribution and metabolism.
• Hydration – Your hydration levels, food, exercise and temporary stomach changes can affect your measurements.
• Body Positioning – How you position your body, where you put your tape, how you breathe and how tight your tape is can affect your results.
  Try to take your measurements from the same place and in the same conditions.
