However, in modern poker rooms, rakeback has evolved, and now just a few sites pay direct rakeback and choose different options: For example, if you pay $1,000 in rake per month, and the rakeback offer is 35%, you will get $350. Rakeback is a reimbursement of a percentage of such fees paid.
For cash games, it's a percentage of the pot (usually 5% capped at a few big blinds), and in tournaments, it's a fee related to the buy-in of the event, usually from 6% to 10%.
Rake is the commission or fee that a poker room charges for offering its services.
