Where can I find unit costs?

[UknowsI]

I have some trouble finding the cost and stats of different units. The stats can be found on Civworld Wiki, but I haven't found the costs anywhere except after I invent them.

I am wondering if I should try to invent tanks, artillery, submarines, fighters or battleship, but difficult when I don't have the cost of the units. So where can I find all the stats for all the units?

I wish they were listed in the Wiki too, but they can be found in the game's Civilopedia.
