Usage

In informal use, it is quite common for the on to be dropped in sentences such as it all depends how you look at it (rather than it all depends on how you look at it), but in well-formed written English, the on should be retained. In more formal writing, and sometimes for sound, rhythm, or other rhetorical effect, upon is the preferred preposition: You may depend upon it
