US Navy Calculator - Body Fat Calculator

What is my navy fitness level when measuring body fat using the Navy Body Fat Test and Navy Body Fat Chart?

This Body Fat Navy Calculator uses the U.S. Navy fitness formula to get an estimated measuring of body fat percent. Use a tape measure then enter your waist, hip, and neck measurements. Combine these measurements with your gender and height and this navy calculator will estimate body fat percent, lean mass, fat mass, and your general navy fitness category. (You can see the Navy Body Fat Chart by clicking the down arrow icon right under the results.) The water displacement test is the most accurate way to determine body fat percent, but the Navy Body Fat test or YMCA formula is accurate within 1-3% for most people.

Unreal   Mine says I'm 12% body fat but I look more like 20%. - 7/22/2016 1:59:35 PM

Ann   How does this calculate hour glass women? My chest to breast difference is rather large, additionally my largest chest measurement is the same as my hip. These parts are not ALL muscle. Does this calculator account for that? Does any tape measure calculator account for that? - 7/20/2016 11:58:02 AM

John   Steve and Ralph you need to be under 10% or under to be able to see your abs....Don't want to say what my BF is! - 7/15/2016 5:06:06 AM

Jamar   @Steve and @Ralph. That's perfectly normal. Abs depend on body type as well but normally (with a few rare exceptions) abs are only visible at 10% or less. If you want to go ryan reynolds like you should aim at about 6%. I'm at 8% or 9% depending on how I calculate and even then they're there but not all that visible. So 14% and a little tummy is perfectly normal. - 6/3/2016 4:48:33 AM

Waleed fahmy   how much is the accuracy deviation of this method ? it gives me 17% fat percentage while when it is measured by bathroom fat scale it gives 24% which is more accurate ? - 5/30/2016 4:41:05 PM

jeremy clark   I think people have false assumptions as to what percent they will start seeing abs. My buddy who competes every year in men's physique has 4.5% and all of his midsection looks ripped. Everyone is different but percentage of fat is only fat/total weight. If you have 12% body fat but keep most of that fat in your but, your butt will look bigger and your abs shredded. If you are like me who tends to keep body fat in the stomach area, then even at 12% (which I am) i will not look shredded in the ab section. The rest of my body looks really cut, but abs are the sticking point and if at 180 lbs and 12% body fat you have 21 lbs of fat, that's still a lot of fat, especially if it is sticking around the mid section. I mean has anyone seen what 10 lbs of pure fat looks like? - 5/6/2016 11:11:44 AM

tracy   When I had my fat percentage done at the gym using caliphers they had me at 27 percent body fat. The rest of my body is pure muscle. I am a female. If I were a male I would be acceptable using these calculations. I do have big hips, breast and butt though. Hourglass figure - 5/5/2016 8:25:37 AM

raquelf   Hola - 5/4/2016 12:24:02 PM

Glenn   I'm so frustrated with this. I'm literally 1 inch either way from being 'ok' by these standards. 17 inch neck and 42 inch waist is 26% but if I go up just ONE inch in neck or down just ONE inch in waist I'm magically 2% less bf and 'within standards' according to the new rules. I'm not in the best of shape, i'll admit, I definitely need to lose the love handles, but it's just incredible how much difference a single inch can make or break a career. getting old sucks, but this system sucks just as much :(. Maybe I'm just hating because I'm not skinny anymore lol... - 4/15/2016 1:21:52 PM

Doc   I'm a chiropractor, and a clinical dietician. After using calipers and electronic scales or hand grips, my practice shows that this method is by far the most reliable. I usually do multiple (5) methods and average them, this one almost always is within 1% error ratio. - 4/7/2016 7:50:15 AM

Ralph   Steve, I think so too, I'm scoring a 14% bf, but I still got a tummy, no visible abs either. - 4/4/2016 3:39:58 AM

sigh   If I was a male I'd be considered fit...but add in my damn hips and I'm obese :( - 4/1/2016 5:58:49 PM

Steve   i dont believe this is accurate says im 14% Bf but i dont have visible abs i think this is very un lickly and would score my self at 17% - 3/15/2016 10:13:46 AM

PopeyeUK   This matches my BIA machine and they track each other with changes. i.e. waist decreases % here always matches my BIA within 0.2% - 3/14/2016 2:23:25 AM

Maria   Danika, no, overweight is not the same as obese. Obese means being at large risk for disease. It's when you're so overweight it starts being dangerous. - 3/5/2016 3:11:39 PM

Jochen   Blah - 2/25/2016 10:34:26 PM

Danika   Debbie Rodriguez, over weight is not acceptable, over weight is obese. - 2/5/2016 8:17:59 AM

DZ   Is this accurate? - 1/27/2016 9:33:32 AM

Debbie Rodriguez   sorry, not seeing a category between Acceptable and Obese. Does Acceptable include overweight? Thanks. - 1/6/2016 11:21:47 PM


The Body Fat Navy Calculator is a Good Tool for Measuring Body Fat and Navy Fitness Level

The comments show passionate emotions and controversial disussions over this Body Fat Navy Calculator! Whether you like the results or not, we've had a couple of recruiters tell us they use it all the time. Please keep in mind that we did not develop the Navy fitness criteria, we just created this Body Fat Navy Calculator using their formulas and interpreted from their body fat chart as a way to help people who are monitoring and measuring body fat. I haven't been able to verify this, but I would guess the Navy's body fat test was developed decades ago by men and during a time when it was only used on male recruits because female servicewomen were not in combat roles.

No body fat percent calculator will be very accurate for people with a very muscular build. There is no argument that a hydrostatic or underwater test is by far the most accurate tool for body fat test tool, but it is not a practical tool to measure ongoing progress due to cost and availability.

There are other formulas for measuring body fat. You may also be interested in another body fat percent calculator: YMCA Body Fat Calculator, 3 Skinfold Body Fat Calculator, 4 Skinfold Body Fat Calculator, and 7 Skinfold Body Fat Calculator.
