It would probably be cheaper (and more convenient and faster) to take the train from Amsterdam to Paris.
You can leave from either central Amsterdam or Schiphol and arrive at either Gare du Nord or CDG.
The fare is only 90.50 in second class and €147 in first.
A great thing about train travel is that you don't have to pay the exorbitant airport taxes that can sometimes literally comprise 50% or more of the base fare.
