How much does Navy Federal require you to deposit to open a bank account?

Both brothers are active duty in the Marine core and both recommend that I open an account with Navy Federal. I finally got my first job working at Walgreen and will get my first pay check next Friday ... I'd like to open a bank account with that first check so I can set up direct deposit as soon as I can... I'm sixteen, does my age matter when it comes to opening my own account?? I mean I am hired as a full time employee and I'm trying to save up to buy a 2011 Kia Soul(: Easy questions I just want a more solid answer to, thanks! (:
