TOOL: When are buildings worth their money

[Shivatis]

I made an excel sheet to determine ROI of buildings.
It includes churches/cathedrals, workshops/counting houses and manufactories.
It works for any nation (even mutapa).
Just type in some numbers/modifiers (dev, autonomy, production efficiency etc.) into the blue boxes and it will tell you in the green boxes, when you will make profit.
I thought I would share it with the community. You find it in the attachment. Have fun.

Can someone explain why Mutapa is an extra slot?
Is that just because of the 3 buildings you buy during the disaster?

Mutapa has a mission, which (after completion) grants extra dev, whenever you build something.

Wait, that stays for the entire game?
Or rather does the decrease in dev also stay?
Because that would be way more interesting.

Upgrade it to give ROI estimates when taking loans to build buildings

this mechanic stays for the entire game, unless you form another tag. and you keep the dev (unless you delete a building).
for example:
building church/cathedral: +1/2 base tax
building workshop/counting houses: +1/2 base production
building manufactory: +2 base production
etc.
