    OP: Thanks for posting this...

    I know that 'Individual Results Vary' but if anyone is curious, this equation was within1/2 a percent of my BodPod reading! (Only 0.4 % difference).

    Just an aside for those of you that mention wanting to get a BodPod anaylsis,
    I splurged on a reading for my 40th birthday, but forgot that I'd have to pay yet again to find out if my body fat % improves or not! :laugh: What I should do is get a home body fat scale, note how it compares to / or calibrate to the BodPod analysis number and keep track that way.

    I was thinking that the body fat calculator probably isn't as accurate because it only takes weight and waist size into account, but now that it gave me a 21% body fat percentage, Im a believer!! LOL

    None of these calculations are accurate but it's a decent estimate most of the time.

    I found this equation shortly after I started here at MFP and I've used it ever since. Recently updated it and it made me smile. :smile:

    pretty sure i did it wrong... second to last number was 33.4, which sounded right to where i am now on body fat, but last number is 17.3 is that where i should be? and if so, how do i calculate what body weight that is for me? Sorry if this is redundant, just got on here for a quick second

    With the healthstatus.com calculator and rounding up on all the half inch #s -
    your body fat percentage is estimated to be 21.31 % using the U.S. Army body fat algorithm, or 14.18 % using the U.S. Marine body fat algorithm, or 16.56 % using the U.S. Navy body fat algorithm, or 15.84 % using the formula developed by the YMCA.

    These methods are not as accurate as a water displacement test, but is usually within 1-3% for most people. If you have a very small waist, it will show a low value. On the other hand, if you carry all your extra weight around your middle, you may have an elevated percentage.

    I guess I'll stick with the mirror method. :wink:

    I finally did the calculation and it's a lot better than my tanita scale (which I know I shouldn't count on anyway)! 27ish %.

    I'm missing something:

    Factor 1 = (125*.732)+8.987 = 100.487
    Factor 2 = 6/3.14 = 1.91
    Factor 3 = 27*.1257 = 4.24
    Factor 4 = 36*.249 = 8.96
    Factor 5 = 8.25*.434 = 3.58
    Factor 1 + 2 - 3 - 4 + 5 = 92.78

    You're missing calculating your body fat weight (total body weight minus lean body mass) and then multiplying your body fat weight by 100 and dividing that by your total body weight. I come up with 26% (rounded up) for you.

    well than I must have done something wrong, because based on my last caliper test I had 13%, and 111 of my 127 (at that time) that was lean mass. Since then the scale hasn't moved, but I've added more lean mass.

    Where the heck is my waist anyway? Since I am one of those men that is pretty lean except for a belly, it's hard to tell. I wear a size 36 pants, but my belly extends a good bit past that!
