It is disappointing, but the Navy discontinued the use of their official PFA calculator. The Navy PRT Calculator and Elliptical calculator is now now behind a CAC login maintained by the Navy Personal Command.
Access the official Navy Elliptical Calorie Calculator from www.NPC.navy.mil
There are a few non-official PRT Calculators that I have found. Click here for my Top 4 Navy PRT Calculators.
For those of you computer savy, I am willing to pay someone who can come up with a calculator which can be used on this wordpress enabled site. If you are interested please contact me at: jc (-at-) navy-prt . com
