What is the cost of RCI Platinum membership?

I'm curious to know, what exactly is the financial obligation one faces when they decide to become an RCI Platinum member? I understand that this level of membership comes with a range of benefits and privileges, but I'm particularly interested in the monetary aspect of it. Could you please clarify the cost of acquiring an RCI Platinum membership? I'm eager to weigh the costs against the potential rewards before making a decision.
