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.

Bevaboo   I am LOLing at a lot of these posts about this calculator being 'rigged', mostly because I was looking at this and thinking that, surely, I have more than 22% body fat. But, according to many of you, this calculator is off in the opposite direction, and I'm actually, what, about 13% body fat? It sounds to me like this is a good tool for general calculation, but if you are a special snowflake, someone with big muscles or big boobs, for example, you're better off paying for the hydrostatic test. I'm not a special snowflake, so I'm inclined to trust this. I'm still going to compare its results with other methods of measuring body fat percentage, but I think we should all keep in mind that math doesn't change as time passes. Pythagorus developed his theorem in 5th century BCE, and you know what? It's still valid. If you had 25% body fat with a given waist and hip size in 1949, you're going to have 25% body fat in 2015. Math doesn't change. - 1/14/2015 3:13:24 PM

FutureSailorWerner   Dunking is accurate, this table is generated off of most standards, however, I am not above 6'0" and weigh 225. I can run a mile in 7.55 and pass the PFT no problem once I'm in. - 1/4/2015 1:08:14 PM

Retired24Years   I am 67-years old, retired Navy and continued to be active and fit. I have been dunked and used the tables. I have found the tables to be within 1/2% of the dunk tank BF percentages. The table are quit accurate. The table where first used as a replacement of the MBI calculations that where once used and did not consider body composition. Thus, highly fit individuals where no passing the test in the early 1970s. One half inch increase or decrease (on me) equals one percent body fat (+/-). In reading some of the other comments my reactions are that if you have a waist over 38" you have a problem. If you are over 220# and not 6'-4" you have a problem. If you have a problem with the table; get dunked. Dunking doesn't lie. - 12/18/2014 7:18:42 AM

Shaaki   Thanks navy seal lol - 11/20/2014 5:20:11 PM

HN Graham   This is rigged, LOL. - 11/13/2014 10:00:54 AM

kk   to lmao: 40" waist 19" neck 240# I'm not saying I'm solid muscle but at age 48 I don't think I could lose more than 20 pounds. At age 18 I had a 38" waist at 225". These scales are only a general guide. - 11/3/2014 8:16:52 AM

kim   i love cheese - 11/3/2014 7:50:36 AM

becky sucks   they say a 100 lb 23 yrs old female has 85 % lean mass with 15 % being fat. probably if u cut off my boobs i bet i weight a crap ton less. claims im athletic. so true cant sit my ass down. yeah had a kid too. whats ur excuse!stay jealous! sum how mine is perfect.i didnt have an issue using it. - 10/27/2014 11:44:00 AM

forreal   I work around Navy Sailors and I say this is some CRAP! The Navy has alot of FAT SAILORS walking around here. Iwould not trust this at all - 10/6/2014 5:13:12 PM

lmao   lol at everyone frauding their stats. Sorry but if you have a 40in waist then you are not solid muscle at all! And 18% on calipers but 34% based on waist to neck ratio?.....yeaaahhh suuurre lol next time have a professional do the calipers. For all the heavier set people on here the tape will actually be more accurate for you. Accept your bf and lose the weight! - 10/5/2014 5:46:30 PM

Christine   This is one of the craziest tables I've seen. I'm a very average female and calipers place me at 25%, which medical tables say is right smack in the middle of the healthy range. - 9/17/2014 11:31:36 PM

CL   This calculation measurement is antiquated and does poorly to measure body fat. I tried this method and came back at 34%. Calipers place me at 18%. - 8/26/2014 4:04:56 PM

jon   Navy standards are complete crap. I'm 6'2 216 and almost solid muscle but according to the navy I'm over my body fat percentage. But you see fat bodies walking around making tape that look like bag nasties in their uniforms. So I get punished for being physically fit and healthy and fat asses get to keep skating by. - 8/9/2014 9:41:39 PM

Lori   I'm 5'-4" and 129 pounds, and this calculator says I'm obese. I'm a size 6, the smallest size at most stores. Here's a recent photo of me: - 7/12/2014 6:30:18 AM

Becca   I love it. i was navy for 4.5 yrs and knowing my make up helps me to manage my life and be able to see the changes as they happen. i love that i can do it online quickly too. i will always suggest looking at body fat make up in sted of just pounds. pounds have always been an issue for me. - 7/2/2014 9:50:53 AM

Erin   I would love more info in opening and starting a fitness center. - 5/29/2014 12:06:39 AM

name   don't know what bob is talking about. 5'4", 96 lb male with a 26 inch waist and 13 inch neck comes out to 6% body fat and athletic body fat category. - 5/28/2014 12:27:42 PM

Chief   To clear up confusion: for the Navy the weight/height is conducted first, if you pass you do not conduct the measurements. If you do not pass the weight/height then measurements are conducted. For (waist/neck) measurements weight is not a factor, but height is. Although it is true that the measurements are to be taken with Navy Standard PT gear on, the tape portion is done against the bare skin and the amount of weight that the standard PT gear adds is negligible. There is one spot that isnt accurate on the tool, though. Next to neck it says "at narrowest". The instruction states: "The neck measurement will be taken on bare skin, at the point just below the Adam's Apple and perpendicular to the long axis of the neck." which may not necissarily be at the narrowest point. So, buff up that neck people! - 5/19/2014 8:15:49 AM

Mike   Far from accurate. Few years back the navy(Released in an issue of NavyTimes) even admitted it isn't accurate but it is still the standard they use because it requires no training/equipment(other than a tape measure) to administer. Oh and to the TM person current standards are from bare skin not through a shirt. - 5/15/2014 2:17:05 PM

TM   Actually, measurements for the Navy test are supposed to be taken clothed with a light tee shirt and shorts. Bet that will mess up your results even more! - 5/9/2014 10:16:25 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.
