Unfortunately, there is no "average bail amount" for such matters. Bail is set on a case by case basis, and it not only depends on the type of criminal charge (the theory generalizes that when there is a greater risk of punishment - long time in jail or capital murder crime - there is a greater likelihood of flight risk or breaking bail) but it also depends on the character of the defendants. When bail is set, there is usually a history of the defendant (and his or her record as regards showing up for court, having warrants for missing court dates, trial; breaking bond conditions in the past, etc.) that is read to the presiding court officer (judge or magistrate). It is the latter that generally determines the amount of bail. Good luck.
