As far as I have experienced, every war is -5%, whether you have 5 or 10 wars, thus 10 wars equals -50% morale influence.
I have never known it to be otherwise.
So lately I've been unwillingly testing wether it is true that no matter how many enemies you have, your morale can't drop more than 25 points because of ongoing wars. Now... actually it can, although it's not being projected like that.
In the projection below it says my morale will drop (daalt). Although the green numbers are higher than the red numbers and thus it should rise...

After day change it did drop....

It's not because of ecnonomical sabotage, I checked for that, however I noticed 1 thing in common for all my core provinces that I checked. The morale calculations would be correct if for every enemy that I have I would lose 5 morale points (so 45 in total instead of 25). Some have stabilazed 20 points lower than what is calculated. I can flood this toppic with screenshots of all of them, but I'm too lazy.
My neighbour seems to have the same problem. He has lvl 5 fortresses (=+25), he had 100% morale, so they are really good neighbours to each other (=~+12) and his morale is dropping as well. On another worldmap I "tested" it as well with the same result. Moral drops lower than what is calculated for.
This makes playing in certain situations a really big chalenge.
I can't explain the morale dropping other than that the projected values you see ingame are incorrect.

In that case, could Bytro maybe atleast project it correctly?
it states it correctly when I look at my stats. however, I ofc never have 10 simultaneous wars... 5 is already hard to maintain, in terms of moral. anyone who does have 10 simultaneous wars by his own doing anyway doesnt need the additional information provided, because if you do not know yet not to start 10 wars, then what use would the information be? 
That's not really important for the discussion Pontus, but I didn't start most of my wars and as many refuse peace there are only 2 ways to end them. I die, or they die. If you do to well or get to big the rest teams up.
The morale penalty because of wars should max out at -25 points if you have 5 or more wars ongoing. It says so in the morale display ingame under the "i" button, it is in reality it doesn't. In both my games the morale displayed in my provinces (dozens of provinces) would be correct if the -5 morale points for every enemy keeps stackingup. like -50 for 10 enemies. -35 for 7 enemies. My neighbour also has morale droppings because of laods of enemies despite lvl 5 fortifications. And it's not because of spies. I use tons of spies and I know how they work and wenn they are present.
Now I gess the guys from Bytro are mostly German computer engineers and so on and probably lack some communicative skills. I can't read your minds and know wether you are aware of it, are investing it or are working on it.
