How is the rakeback calculated in general?
If you have signed up for a deal which will give you 25% rakeback, you will simply recieve a quarter of the rake you have generated back directly to your poker account in the beginning of each month. For example, if you and another player play a hand where the total rake is $2, the two of you have been charged $1 each in rake and your rakeback from that pot would be $0,25 with 25% rakeback.
