In Oklahoma, the bail bond premium is set by state law at 10% of the bond amount. On a $10,000 bond, the premium is $1,000. This fee is non-refundable — it is the cost of the bonding service, not a deposit, so it does not come back to after the case is over. The premium amount is the same at every licensed bail bond company in Oklahoma, so when you compare companies, compare service and terms, not the fee.
