At this rate, he won't have to explain with no new subscribers. :p

This is what i found somewhere:
Total CPU power: 8x 2500 MHz
total memory: 2048 MB
Total diskspace: 170 GB
Total bandwidth: 2000 GB
IP Addresses: 10
350.48 Euros for 1 month.

the servers they have are probably less which means its about 100-200 euros, per month per server

These are just brief quotes from the player account Battousai90290 asking via support tickets as to why Graal doesn't advertise for new players?

"But yeah, I'm going to start advertising outside of graal, to try to get more players back. I just don't know how to go about that yet... "

Me: As a player, you shouldn't have to worry about that. But I know your dedication as well others, we want to see more players... :\

"Yeah, it shouldn't be my place to do so, but Stefan told me that he isn't going to advertise, so if we want more players, we have to get them ourselves. Pretty sad. "

"He doesn't care. He made his money, for all he cares it can die. He said advertising would be "a waste of money. if you want more players, help advertise yourself like Tig does "

There's part of the answer.

This is offtopic, sorry. You don't need to care about the costs which we have. If you have fun playing or developing then do it, but we will not discuss the details of running everything especially in a thread which only purpose seems to be to question prices or strategy.
You can find enough information about the hardware and software on the forums and we often give details when talking to players and developers.
