The simple answer for this type of question is "it depends". Obviously someone who plays $0.10/$0.20 no-limit holdem once a week won't get as much rakeback as one playing $5/$10 pot-limit Omaha for five hours a day, and then there are all those poker players in between.
Thankfully, there's a very easy way to figure out approximately how much you will make on average using our rakeback calculator. The results you get from the calculator are not exact - you have to factor in things like hands per hour (table speed) and your playing style. If you are a loose and aggressive players who frequently splashes the pot, you will automatically pay more rake and hence get more rakeback (not necessarily a good thing, just a fact).
Still, the numbers you get from the rakeback calculator provide a pretty good average and should give you a fair estimate of how much you can make on average.
How to Use the Rakeback Calculator:
It's very simple and straightforward.
Remember, that if you haven't played with rakeback before, the sum you're getting can be considered money lost on every poker session without rakeback. It also points out how big a difference you can count on when getting a better rakeback deal.
Again, these are no exact figures, but reasonably accurate for most players.
