The calculator uses a different one-site equation and limit table for each selection.<\/li>\n<li>Enter <strong>Age<\/strong> in whole years. The calculator accepts ages 17 and older and uses your age to select a body fat limit.<\/li>\n<li>Enter <strong>Body weight<\/strong> in pounds. Use a current measurement rather than an old or target weight.<\/li>\n<li>Measure around your abdomen at the navel and enter <strong>Abdominal circumference<\/strong> in inches, to the nearest 0.5 inch. Keep the tape level and avoid pulling it tight enough to compress the skin.<\/li>\n<li>Read <strong>Estimated body fat<\/strong>, <strong>Maximum allowed for your age<\/strong>, and <strong>Meets the body fat limit<\/strong>. Check <strong>Difference from limit<\/strong> to see how far the rounded estimate is from the maximum.<\/li>\n<\/ol>\n<h2>What the Army body fat estimate means<\/h2>\n<p>Body fat percentage describes the estimated share of body weight made up of fat. This calculator applies a one-site equation using abdominal circumference and body weight; it does not measure body composition directly. Age does not change the estimate itself, but it changes the maximum used for comparison.<\/p>\n<p>The result is rounded to a whole percent before the limit check. An estimate equal to the maximum is shown as within the limit. A negative difference means the estimate is below the maximum, zero means it is at the maximum, and a positive difference means it is above the maximum. These differences are <em>percentage points<\/em>, not pounds of body fat.<\/p>\n<p>The calculator uses these limits for its comparison:<\/p>\n<table>\n<thead>\n<tr>\n<th>Age (years)<\/th>\n<th>Male maximum<\/th>\n<th>Female maximum<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>17\u201320<\/td>\n<td>20%<\/td>\n<td>30%<\/td>\n<\/tr>\n<tr>\n<td>21\u201327<\/td>\n<td>22%<\/td>\n<td>32%<\/td>\n<\/tr>\n<tr>\n<td>28\u201339<\/td>\n<td>24%<\/td>\n<td>34%<\/td>\n<\/tr>\n<tr>\n<td>40 and older<\/td>\n<td>26%<\/td>\n<td>36%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>For example, the worked example\u2019s unrounded estimate is 21.08%, but the comparison uses 21%. Since the limit is 22%, the displayed difference is \u22121 percentage point. If a measurement places you close to a cutoff, even a small change in the entered circumference or weight could change the rounded result.<\/p>\n<h2>Measurement tips and limitations<\/h2>\n<p>Measure abdominal circumference at the navel as requested by this calculator, and record it to the nearest half inch. Use the same measurement method when checking progress: a different tape position, tape tension, posture, or time of day can change the reading. Enter pounds and inches only; the equations are not designed to accept kilograms or centimeters without conversion.<\/p>\n<p><strong>This is an estimate, not an official Army tape-test result.<\/strong> An official determination requires a certified measurement performed under the applicable Army procedures. Other eligibility rules or assessment steps may also apply. Do not use a calculator result alone to establish compliance or make a personnel decision.<\/p>\n<p>The equation is intended for plausible body measurements. If the entered values produce an estimate below 0% or above 100%, the calculator reports an error rather than displaying an impossible percentage. It also cannot describe where fat is distributed or replace a clinical body-composition assessment.<\/p>\n<p>For a separate measure of body proportions, try the <a href=\"https:\/\/wpcalc.com\/en\/beauty\/waist-to-hip-ratio-calculator\/\">waist-to-hip ratio calculator<\/a>.
