How do you determine the upkeep cost of a unit?

For non-sacred units, it's: (recruit cost) / 15.

For sacred units it's: (recruit cost) / 30

It's zero for most summoned units, however there are some exceptions. Mostly it only applies to ones that are recruitable for another version of that nation in a different age or from a magic site. Check Edi's unit database to be sure for summons.

Right, there are exceptions. Trolls are not very expensive (80/2 or a couple of Earth/Water gems), but their upkeep is extremely high. Summoned too! So be careful with using large troll armies - with all their bonuses, such army can crush your budget

I heard, that some summoned demons reuires upkeep too. Or it looks like there`s upkeep...Somebody knows?

See above.

And if you use the Transformation Ritual (Alt-7) do the transformed unit still have the upkeep of the original one or it becomes a free upkeep unit?
