Rakeback is a certain percentage of the rake automatically refunded to you at designated intervals. At some rooms, there's a minimum threshold that must be reached before any RB payment occurs. At others, you'll obtain whatever rakeback you've earned when the time for payment rolls around no matter how small it is.
Almost all rakeback deals include tournament and sit-n-go fees within the total sum on which the RB is calculated. However, bonuses and other promotional winnings may be deducted from this total.
If you have the option to play with rakeback but you elect not to exercise it, then you may be costing yourself hundreds or thousands of dollars per month. For more information about rakeback and to sign up at the best online poker rakeback sites, check out our list of RB offers.
