Max Nerds
There's no shortcut to figure it out other than to actually hit the maximum. On Saturdays at 2pm, ea has been sending reinforcements, which will show you the maximum. That would be the best bet if you don't want to waste any nerds.
Otherwise, you can find a chart that shows you what you get at each castle upgrade level and calculate it from there. The max maximum is 130 (if all three castles are at level 19 or higher).
