At the moment, not at all.  Ballpark calculation:

An older version of a Falcon 9 reportedly had 488 tons of total
fuel, 147 of it RP-1 (a modified kerosene).  Liquid oxygen is
quite cheap, and if we give RP-1 a cost of 1 dollar per kg,
we probably are in the right ballpark.  So, around 150 000 Dollar
per launch.

This is _very_ low compared to all the other costs.  A launch
cost around 50 to 60 million dollars now, if I remember the
figures right.
