I added a link to my modified version of Stoneford's T5 calculator at the end of his stickied thread in the strategy section. PS: I do use a version with projected stats and costs for the lvl2 and lvl3 T6 buildings (there seems to be a pretty consistent 15% increase of stats between T5 and T6). I didn't post that inofficial version though
