The only thing that I know of that has "upkeep" are troops which consume food. If you hover the cursor over the Food icon at the top of the screen (referring to computer browser access, don't know what mobile app looks like), it will show you what you are producing in excess of what the troops are consuming. If the food count is red, then the troops are consuming more than you are producing.
