The ACC falls behind when it comes to TV deals and payouts per school. Notre Dame is only a partial member so they only get part of the money. In 2019, Notre Dame was paid $7.9 million from the ACC deal. Full ACC members were paid $29.5 million each.
For comparison, the Big Ten paid out 54 million per school, the SEC paid 43.1 million per team and the Big 12 paid 33.6 million. These are just the payouts for TV deals and the ACC is closer to the Pac 12 than the Big Ten/SEC.
Notre Dame gets paid $15 million annually from NBC and the $7.9 million from the ACC puts them around $23 million. If you add in the $9.0 million a year from the Under Armour deal, that still puts Notre Dame behind the Big 12 in just TV revenue.
Now Notre Dame football isn't hurting financially, far from it actually. Notre Dame is a private institution and they don't report their financial numbers, but Forbes estimates Notre Dame made $112 million in revenue in 2018. That puts them in the top 10 earners in college football.
