The weekly costs for the Academy will be listed as "Youth expenses" in your weekly financial report.The academy does not have any other staff, they rely on their parents taking care of transport, bruises, injuries etc - which they do without any additional cost.At the same time youth academies have no income either, the only spectators are usually just parents and friends to the youth players.

Apart from that the only additional cost you will get is if you tell your scout to search for players in another region, then you might have to pay for his plane ticket.
