Initial bond amounts vary by County in Florida. Many counties will release you on pre-trial release (PTR) for a first offense non-violent third degree felony. The reality is that it is generally better to be able to post bond than to be released on PTR because bond is less restrictive.
In Broward County, a typical bond for a third degree Grand Theft charge is $1500. A failure to appear or new arrest will result in a bond revocation. If you are turning yourself in, go see a bondsman first to process the paperwork in advance.
