It varies, but there is free parking available further from the arena.
The cost of parking close to the arena I think most likely depends on the event & well how close you actually want to be....I was there just a couple of weeks ago and I seen signs for parking as low as $7 but as high as $40.
They have free parking, if you want to park up close it costs but not sure how much. We just parked in the free stuff.
