Before any of my home game starts (Say 15mins before right until the "live" game starts) in the "Manage My Team" page I can see how much money I will have after the game. So I can tell how much money I will get from attendance. I can also see this while the game is on.
It's only on the "Manage My Team" page, if I click on Finances it shows what I believe to be the correct amount.
