Yesterday I saw above the details of a deal, a new field call "Choose a billing plan" and in general it seems that you can enter recurring revenue in different periods (weekly, monthly, annually, etc.).  

Does these values affect directly the deals total value amount or is more an internal reference value for the user?  

The reason I'm asking is because we always register the total contract amount in the total value but the total amount is divided between one-time setup fees, monthly fees and annual fees; we have created it custom fields to show these numbers, but doesn't have any direct impact to the total value field (see below) .  

Any information will be appreciated.
