On the Itinerary Details Page when you hover over the Information Button next to Selling Price you will see the different components that makeup the Selling Price. 

Note: Your client will not be able to see the cost breakdown, only you will be able to access this from the Itinerary Details Screen. 

Supplier Cost: The cost Wilderness charges to book the trip

Upfront Cost: Gorilla Permits, international and commercial flights, etc., 

My Margin: The 22% or 20% you have set for YZ or 15% for Wilderness Direct  **This will change soon due to an upcoming itrvl update that will change our pricing from rack + 5% & 7%

Escrow Service Fees: This is technically a credit card fee but we do not call it this when talking to clients. You should only ever be exposed on this when you are doing a full cost breakdown for a client. Chat to James, Em or K on how to handle this. The clients do get the opportunity to take this off if they pay by wire transfer.
