Just a rough estimate, lets look at this year first!
This season 2011-12: Coppa+Serie A
Serie A; 19 Home games
Coppa italia; 3 home games
Revenue so far
~22 mio euro
3 games to go, so around 26mio euro maybe?
I have not taken into consideration what a coppa italia win would give in prize money and the same goes for a Scudetto.
Next season
Season 2012-13; Coppa+Serie A+CL
Just for easy math lets say at least the same income for Serie A + Coppa(Semi finale spot)
roughly 26 mio euro
+ CL money
Income in CL
Revenue for attendance: 1.4 mio euro for each game? : 4.2 mio euro
Group stage: €3,900,000
For each match in group stage: €550,000
= 11.4 mio euro for participating in CL!
+
depending on how we are doing in each match an extra income of either Group match victory: €800,000 or Group match draw: €400,000
So
6 losses = 0 extra
6 wins = 4.8 mio euro extra
and qualifying from the group stage:
Round of 16: €3,000,000
Quarter-finals: €3,300,000
SO...
2011-12 : ~26 mio euro + prize money for coppa and scudetto
2012-13 : ~37.4 mio euro + 4.8(max)+ 3+1.5(qualifying+extra match income)+3.3+1.5(qualifying further+extra match income) = ~53mio euro (for six victories in Group phase and reaching the quarter finale in CL
Just a simple calculation on how much revenue could (should) increase next year
