Rake vs Bonus question

[EsandWhizz]

I play on HollyWood Poker with no rake but i got a $1250 bonus payed in $250 increments. Iv cleared $500 dollars of it so far and estimate it takes around 12000 hands at 6max 50nl to make $250 dollars. Is this equivalent to 25-30% rakeback? I want to stay on the Ongame skin as im beating it and move about the various sites taking bonus. Obviously if i would make more with rakeback on a different site i will have to think about moving on. Thanks for any replies.
